Inflammation and ulceration of mucous membranes, most common with high-dose chemotherapy and head/neck radiation (Correct answer)
Muscle inflammation from immunotherapy
Bone marrow suppression from surgery
A skin rash from targeted therapy

Correct answer: Inflammation and ulceration of mucous membranes, most common with high-dose chemotherapy and head/neck radiation

Mucositis is painful inflammation and ulceration of the mucosal lining of the GI tract (especially the mouth), most commonly caused by high-dose chemotherapy, head and neck radiation, and stem cell transplant conditioning regimens.

Question 6: Allopurinol is administered prophylactically before chemotherapy in high-risk hematologic malignancy patients primarily to prevent:

Uric acid nephropathy from tumor lysis syndrome (Correct answer)
Mucositis
Cardiotoxicity
Neutropenic fever

Correct answer: Uric acid nephropathy from tumor lysis syndrome

Allopurinol blocks xanthine oxidase, reducing uric acid production and preventing urate crystal deposition in renal tubules during TLS.

Question 7: Which of the following can contribute to peristomal candidiasis?

Daily soap washing
Overexposure to sunlight
Excessive moisture (Correct answer)
Dry skin

Correct answer: Excessive moisture

Peristomal candidiasis, a fungal infection, thrives in warm, moist environments. Excessive moisture around the stoma, often due to leakage from an ill-fitting pouch or inadequate skin drying, creates ideal conditions for yeast growth. Maintaining dry, clean peristomal skin is crucial for preventing this common complication.

Question 8: What is the primary goal of cytoreductive (debulking) surgery in ovarian cancer management?

To relieve bowel obstruction caused by pelvic tumor masses
To establish a definitive tissue diagnosis of the cancer
To reduce tumor burden to optimal residual disease to enhance chemotherapy effectiveness (Correct answer)
To cure the cancer through complete removal of all visible disease

Correct answer: To reduce tumor burden to optimal residual disease to enhance chemotherapy effectiveness

Cytoreductive surgery aims to reduce residual tumor to less than 1 cm, which significantly improves response rates and overall survival with subsequent platinum-based chemotherapy.

Question 9: Which skill is most essential for a COCN when teaching self-care to patients?

Billing and coding knowledge

The metabolic tetrad of hyperkalemia, hyperphosphatemia, hyperuricemia, and hypocalcemia is diagnostic of tumor lysis syndrome.

Question 32: What is the difference between neoadjuvant and adjuvant chemotherapy?

There is no clinical difference between the two
Neoadjuvant is given before surgery; adjuvant is given after surgery (Correct answer)
Neoadjuvant uses oral drugs; adjuvant uses IV drugs
Neoadjuvant treats metastatic disease; adjuvant treats primary tumors

Correct answer: Neoadjuvant is given before surgery; adjuvant is given after surgery

Neoadjuvant chemotherapy is administered before the primary treatment (usually surgery) to shrink tumors, while adjuvant chemotherapy is given after primary treatment to eliminate remaining cancer cells.

Question 33: What is brachytherapy and how does it differ from external beam radiation?

Radiation delivered only to the brain
Radiation delivered from a source placed inside or next to the tumor, versus from a machine outside the body (Correct answer)
A type of chemotherapy given during radiation
A form of immunotherapy combined with radiation

Correct answer: Radiation delivered from a source placed inside or next to the tumor, versus from a machine outside the body

Brachytherapy involves placing radioactive sources directly inside or adjacent to the tumor (intracavitary, interstitial, or surface), delivering high-dose radiation to the tumor while minimizing exposure to surrounding healthy tissues.

Question 34: What does the WOCN recommend regarding patient education?

Provide only written instructions
Demonstrate care and allow patient practice (Correct answer)
Refer all training to pharmacists
Avoid demonstrations

Correct answer: Demonstrate care and allow patient practice

The WOCN (Wound, Ostomy and Continence Nurses Society) strongly advocates for a hands-on approach to patient education, recommending that nurses demonstrate ostomy care procedures and then allow patients to practice these skills themselves. This active learning approach builds confidence, reinforces learning, and promotes self-efficacy in managing their ostomy independently. It ensures practical competence.

Question 35: According to the WHO analgesic ladder, what is the first step for managing mild cancer pain?

Non-opioid analgesics such as acetaminophen or NSAIDs (Correct answer)
Radiation therapy for pain control
Nerve blocks
Strong opioids like morphine

Correct answer: Non-opioid analgesics such as acetaminophen or NSAIDs

A key aspect of their role is educating patients and their families on self-care, appliance management, and lifestyle adjustments to promote independence and quality of life. They are experts in managing the physical and psychological aspects of living with an ostomy.

Question 45: What is tumor lysis syndrome (TLS)?

A metabolic emergency caused by rapid cancer cell death releasing intracellular contents (Correct answer)
A side effect of radiation therapy on the skin
A chronic fatigue condition in cancer patients
A psychological disorder following cancer diagnosis

Correct answer: A metabolic emergency caused by rapid cancer cell death releasing intracellular contents

TLS occurs when large numbers of cancer cells die rapidly (often after initiating chemotherapy), releasing potassium, phosphorus, and uric acid into the blood, potentially causing kidney failure, cardiac arrhythmias, and seizures.

Question 46: What is the most appropriate action if the patient reports frequent pouch leakage?

Reassess pouching system fit (Correct answer)
Change brands of adhesive remover
Ignore unless skin irritation occurs
Use alcohol wipes more frequently

Correct answer: Reassess pouching system fit

Frequent pouch leakage is a common and distressing issue for ostomy patients, often indicating an improper fit of the pouching system. The most appropriate action is to reassess the stoma size, shape, and peristomal skin contour to ensure the barrier opening is correct and the system adheres securely. A well-fitting system is crucial for preventing leakage and protecting the skin.

Question 47: When assessing a patient's discharge readiness after colorectal cancer surgery with a newly formed ostomy, which factor is most important to verify?

The patient has memorized all dietary restrictions related to the ostomy
The patient can describe all potential long-term complications of colorectal cancer
The patient can independently demonstrate proper pouching system application (Correct answer)
A family member has agreed to manage all ostomy care for the patient

Correct answer: The patient can independently demonstrate proper pouching system application

The ability to independently demonstrate pouching system application using return demonstration confirms the patient has the skill necessary for safe self-care at home.

Question 48: How should a nurse address a cancer patient's misconceptions about pain medication addiction?

Avoid discussing the topic entirely
Recommend alternative medicine instead of opioids
Educate about the difference between physical dependence, tolerance, and addiction in the context of cancer pain (Correct answer)
Agree that addiction is likely and minimize opioid use

Correct answer: Educate about the difference between physical dependence, tolerance, and addiction in the context of cancer pain

Nurses should clarify that physical dependence (withdrawal symptoms if stopped abruptly) and tolerance (needing higher doses) are normal physiological responses different from addiction (compulsive use despite harm), which is rare in cancer patients taking opioids as prescribed.

Question 49: A patient with a new colostomy after sigmoid colon resection for cancer is on postoperative day 2. Which assessment finding indicates the colostomy is functioning properly?

No stool or flatus output during the first 72 hours
Passage of flatus through the colostomy (Correct answer)
Dark purple discoloration of the stoma mucosa
Bright red bleeding noted from the stoma surface

Correct answer: Passage of flatus through the colostomy

Passage of flatus through the colostomy within 24–72 hours postoperatively indicates the return of gastrointestinal motility and is an expected, reassuring finding.

Question 50: Which nutrient is most important for wound healing around a stoma?

Protein (Correct answer)
Starch
Caffeine
Cholesterol

Correct answer: Protein

Protein is a fundamental nutrient essential for all stages of wound healing, including around a stoma. It provides the building blocks for tissue repair, collagen synthesis, and immune function, all critical for healthy skin and stoma integrity. Adequate protein intake supports cellular regeneration and helps prevent complications like skin breakdown.

Question 51: What does recent literature recommend to reduce risk of peristomal moisture-associated dermatitis?

Use of alcohol-based adhesives
Applying petroleum jelly
Proper fitting appliance and skin barrier (Correct answer)
Frequent soap scrubbing

Correct answer: Proper fitting appliance and skin barrier

Recent literature consistently emphasizes that a properly fitting appliance and skin barrier are the most critical factors in preventing peristomal moisture-associated dermatitis. A well-fitted barrier prevents stoma output from contacting the skin, thereby protecting it from irritation and breakdown caused by moisture and enzymes. Ensuring a snug, secure fit is paramount.

Question 52: What are common coping mechanisms observed in cancer patients?

Exclusively seeking second opinions
Problem-focused coping, emotion-focused coping, and meaning-making (Correct answer)
Immediate acceptance without distress
Only denial and anger

Correct answer: Problem-focused coping, emotion-focused coping, and meaning-making

Cancer patients use various coping strategies including problem-focused approaches (seeking information, treatment planning), emotion-focused methods (support groups, counseling), and meaning-making (finding purpose, spiritual growth).

Question 53: Which nursing assessment finding in a patient with acute leukemia would prompt the nurse to immediately notify the physician?

Mild fatigue after ambulation
Sudden onset of severe headache and visual changes (Correct answer)
ANC of 1800/mm³
Platelet count of 90,000/mm³

Correct answer: Sudden onset of severe headache and visual changes

Sudden headache and visual changes in a leukemia patient suggest CNS leukemia or intracranial bleeding, requiring urgent evaluation.

Question 54: Which opioid rotation (equianalgesic conversion) consideration is most important when switching a cancer patient from morphine to hydromorphone?

No dose adjustment is needed since opioids are interchangeable
A 25–50% dose reduction from the calculated equianalgesic dose is recommended to account for incomplete cross-tolerance (Correct answer)
Hydromorphone requires a higher dose than morphine
Hydromorphone should only be used IV, never subcutaneously

Correct answer: A 25–50% dose reduction from the calculated equianalgesic dose is recommended to account for incomplete cross-tolerance

Incomplete cross-tolerance between opioids means the calculated equianalgesic dose should be reduced by 25–50% to prevent overdose.

Question 55: How should chemotherapy spills be managed in a healthcare facility?

Using a chemotherapy spill kit with absorbent materials and proper PPE per facility protocol (Correct answer)
Wiping with regular cleaning supplies
Asking housekeeping to clean it during regular rounds
Covering the spill and leaving it until end of shift

Chemotherapy spills require immediate response using a designated spill kit containing absorbent materials, PPE, waste disposal bags, and decontamination agents, following the facility's hazardous drug spill protocol.

Question 56: A patient is in the immediate postoperative period following cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (HIPEC). What is the nurse's primary concern?

Preventing deep vein thrombosis with sequential compression devices
Assessing for fluid and electrolyte imbalances (Correct answer)
Monitoring for oral mucositis from chemotherapy exposure
Managing systemic photosensitivity reactions

Correct answer: Assessing for fluid and electrolyte imbalances

HIPEC involves extensive abdominal surgery and direct chemotherapy perfusion, causing significant third-spacing and fluid shifts that place patients at high risk for fluid and electrolyte imbalances.

Question 57: A patient with terminal cancer refuses further treatment and asks about hospice. Medicare hospice benefit requires a physician-certified prognosis of life expectancy of:

3 months or less
12 months or less
6 months or less if the disease runs its normal course (Correct answer)
1 month or less

Correct answer: 6 months or less if the disease runs its normal course

Medicare hospice eligibility requires physician certification that life expectancy is 6 months or less if the illness follows its expected course.

Question 58: What is breakthrough pain in cancer patients?

Pain caused by physical therapy exercises
The initial pain felt at cancer diagnosis
Pain that breaks through the skin surface
Transient flares of pain that occur despite around-the-clock analgesic therapy (Correct answer)

Correct answer: Transient flares of pain that occur despite around-the-clock analgesic therapy

Breakthrough pain is a temporary flare of moderate to severe pain that occurs despite adequate background pain control with around-the-clock medications, requiring fast-acting rescue medications.

Question 59: Which Enhanced Recovery After Surgery (ERAS) protocol element is most effective in reducing postoperative ileus in cancer surgery patients?

Early ambulation within 24 hours of surgery (Correct answer)
Prolonged NPO status beginning 12 hours before surgery
Bed rest for the first 48 hours to preserve energy
Routine nasogastric tube insertion postoperatively

Correct answer: Early ambulation within 24 hours of surgery

Early ambulation within 24 hours is a core ERAS component that stimulates gastrointestinal motility and significantly reduces the duration of postoperative ileus.

Question 60: A patient with stage IV cancer shows signs of imminent death (mottling, Cheyne-Stokes respirations, unresponsive). Family is asking if fluids should be started. The nurse's response should prioritize:

Explaining that terminal dehydration is a natural part of the dying process and IV fluids may increase discomfort (Correct answer)
Starting IV fluids to prevent dehydration as a comfort measure
Requesting aggressive hydration per hospital protocol
Deferring entirely to the family's wishes without guidance

Correct answer: Explaining that terminal dehydration is a natural part of the dying process and IV fluids may increase discomfort

Terminal dehydration reduces secretions and edema, and forced hydration can increase respiratory congestion, nausea, and discomfort at end of life.

Question 61: A patient with known breast cancer develops sudden shortness of breath, tachycardia, pleuritic chest pain, and hypoxia. The priority nursing action is:

Notify the physician immediately and prepare for diagnostic workup for pulmonary embolism (Correct answer)
Administer a bronchodilator and wait for resolution
Apply warm compresses and reassure the patient
Encourage incentive spirometry and ambulation

Correct answer: Notify the physician immediately and prepare for diagnostic workup for pulmonary embolism

Cancer patients have significantly elevated VTE risk; these symptoms are classic for pulmonary embolism requiring urgent evaluation.

Question 62: Palliative sedation for refractory symptoms at end of life requires that other symptom management options have been:

Refused by the family but not the patient
Not yet tried to conserve resources
Only tried once each
Exhausted or deemed inappropriate before sedation is initiated (Correct answer)

Correct answer: Exhausted or deemed inappropriate before sedation is initiated

Palliative sedation is ethically justified only when all other reasonable symptom-relief options have failed or are inappropriate.

Question 63: A patient with CLL develops hemolytic anemia and thrombocytopenia caused by autoimmune destruction. This is known as:

Graft-versus-host disease
Evans syndrome (Correct answer)
Richter transformation
Tumor lysis syndrome

Correct answer: Evans syndrome

Question 64: A patient with multiple myeloma is at highest risk for which skeletal complication?

Pathologic fractures (Correct answer)
Osteosarcoma
Osteoporosis without fracture risk
Joint effusions

Correct answer: Pathologic fractures

Myeloma cells stimulate osteoclasts and inhibit osteoblasts, leading to lytic lesions and pathologic fractures.

Question 65: What is the purpose of simulation in radiation therapy planning?

To simulate the patient's emotional response to treatment
To determine if radiation therapy is covered by insurance
To test whether the patient can tolerate lying still
To map the treatment area precisely and create a customized treatment plan (Correct answer)

Correct answer: To map the treatment area precisely and create a customized treatment plan

Simulation uses CT scanning and positioning devices to precisely map the tumor and surrounding anatomy, create custom immobilization devices, and define treatment fields for accurate, reproducible radiation delivery.

Question 66: Which assessment finding indicates worsening cardiac tamponade requiring emergency pericardiocentesis?

Mild tachycardia without blood pressure change
Isolated JVD without other changes
Mild ankle edema
Increasing pulsus paradoxus (>10 mmHg) with hemodynamic instability (Correct answer)

Correct answer: Increasing pulsus paradoxus (>10 mmHg) with hemodynamic instability

Progressive pulsus paradoxus with hemodynamic compromise indicates critical tamponade physiology requiring immediate drainage.

Question 67: A patient is in the early postoperative period following radical prostatectomy for prostate cancer. Which nursing intervention is the highest priority?

Maintain urinary catheter patency and monitor for excessive hematuria (Correct answer)
Start a high-fiber diet to prevent postoperative constipation
Encourage the patient to begin Kegel exercises immediately
Apply ice packs directly to the perineal area for comfort

Correct answer: Maintain urinary catheter patency and monitor for excessive hematuria

After radical prostatectomy, urinary catheter patency must be maintained because blood clots can obstruct the catheter, causing bladder distension and risk of anastomotic disruption.

Question 68: What nursing assessment tool is appropriate for evaluating pain in non-verbal cancer patients?

FLACC scale or behavioral pain assessment tools (Correct answer)
Brief Pain Inventory

Question 70: Which laboratory value is most critical to monitor before administering myelosuppressive chemotherapy?

Serum albumin
Serum sodium
Absolute neutrophil count (ANC) (Correct answer)
Blood glucose

Correct answer: Absolute neutrophil count (ANC)

The ANC is the most critical value because myelosuppressive chemotherapy further decreases white blood cell production, and administering treatment with an already low ANC increases the risk of life-threatening neutropenic infections.

Question 71: Which electrolyte imbalance is NOT a feature of tumor lysis syndrome (TLS)?

Hypercalcemia (Correct answer)
Hyperuricemia
Hyperkalemia
Hyperphosphatemia

Correct answer: Hypercalcemia

TLS causes hypocalcemia (not hypercalcemia) due to phosphate binding calcium as phosphate is released from lysed cells.

Question 72: Which intervention is most appropriate to prevent surgical site infection in a patient undergoing colorectal cancer surgery?

Question 73: A patient with lung cancer develops pulsus paradoxus, hypotension, and muffled heart sounds. The nurse recognizes this as:

Pleural effusion
Pulmonary embolism
Congestive heart failure
Cardiac tamponade (Correct answer)

Correct answer: Cardiac tamponade

Beck's triad (hypotension, muffled heart sounds, distended neck veins) plus pulsus paradoxus is classic for cardiac tamponade.

Question 74: A cancer patient on chronic opioids develops constipation. The first-line treatment is:

Bulk-forming laxatives (psyllium)
Fiber supplements only
Increased oral fluid intake alone
Stimulant laxatives (senna) with or without stool softeners (Correct answer)

Correct answer: Stimulant laxatives (senna) with or without stool softeners

Stimulant laxatives are the recommended first-line treatment for opioid-induced constipation (OIC), as bulk agents may worsen the condition.

Question 75: What is anticipatory grief in cancer patients?

Grief that occurs only after treatment is complete
Grief experienced before the actual loss, often related to anticipated death or loss of function (Correct answer)
A normal response to scheduling treatment appointments
Excessive worry about minor side effects

Correct answer: Grief experienced before the actual loss, often related to anticipated death or loss of function

Anticipatory grief is the mourning process that occurs before an expected loss, which may include impending death, loss of body parts, loss of independence, or loss of future plans and expectations.

Question 76: Why is documentation important in ostomy care?

Compassion fatigue is a state of physical and emotional exhaustion that develops from repeated exposure to patients' suffering, potentially leading to decreased empathy, emotional numbness, burnout, and reduced quality of care.

Question 82: What is the purpose of a belt with an ostomy pouching system?

To provide electric stimulation
To secure the pouch and prevent leakage (Correct answer)
To carry personal items
To compress the abdomen

Correct answer: To secure the pouch and prevent leakage

An ostomy belt is designed to provide additional security and support to the pouching system, helping to keep the skin barrier firmly in place against the abdomen. This added pressure can improve the seal, especially for active individuals or those with irregular abdominal contours, thereby reducing the risk of leakage and extending wear time. It is not meant for compression or carrying items.

Question 83: When should patient education about chemotherapy side effects ideally begin?

Only if the patient asks specific questions
After side effects have already occurred
Before the first treatment cycle during the treatment planning phase (Correct answer)
At the end of the last treatment cycle

Correct answer: Before the first treatment cycle during the treatment planning phase

Proactive education before treatment begins allows patients to prepare for potential side effects, understand when to seek medical attention, and arrange support systems, improving treatment adherence and outcomes.

Question 84: How often should ostomy appliances typically be changed?

Every 3–5 days (Correct answer)
Once a month
Every 24 hours
Every 12 hours

Correct answer: Every 3–5 days

2000/mm³
1500/mm³

Correct answer: 500/mm³

Neutropenic fever requires ANC <500/mm³ (or <1000/mm³ expected to fall), combined with fever, as per IDSA guidelines.

Question 90: A patient with multiple myeloma has a serum calcium of 12.8 mg/dL. Which nursing intervention is the priority?

Encourage a high-calcium diet
Apply warm compresses to the extremities
Restrict oral fluids to 1L/day
Administer IV normal saline hydration (Correct answer)

Correct answer: Administer IV normal saline hydration

Aggressive IV hydration with normal saline is the first-line treatment for hypercalcemia to promote renal calcium excretion.

Question 91: A patient develops syndrome of inappropriate antidiuretic hormone (SIADH) secondary to small cell lung cancer. The primary nursing concern is:

Dehydration prevention
Hypernatremia management
Hyponatremia and fluid restriction (Correct answer)
Hyperkalemia correction

Correct answer: Hyponatremia and fluid restriction

SIADH causes dilutional hyponatremia; fluid restriction is the primary treatment to reduce water retention.

Question 92: When a cancer patient's family asks if 'increasing the morphine will hasten death,' the nurse's best response is based on which ethical principle?

Principle of justice — it is unjust to withhold pain relief
Beneficence only — whatever benefits the patient is acceptable
Doctrine of double effect — the intent is relief of suffering, not hastening death (Correct answer)
Autonomy — the patient decides dose regardless of outcome

Correct answer: Doctrine of double effect — the intent is relief of suffering, not hastening death

The doctrine of double effect holds that an action intended to relieve suffering is ethical even if death could be an unintended secondary effect.

Question 93: A nurse caring for a patient after right hemicolectomy observes that the stoma appears dark purple-brown on postoperative day 2. What is the most appropriate nursing action?

Document as a normal postoperative finding
Apply warm compresses to improve circulation

Question 102: According to best practices, what is the recommended frequency for assessing peristomal skin?

At every routine care session (Correct answer)
Only during appliance changes
Every six months
Only when the patient complains

Correct answer: At every routine care session

Best practices dictate that peristomal skin should be assessed at every routine care session, particularly during each appliance change. This frequent assessment allows for early detection of any irritation, breakdown, or complications, enabling prompt intervention and prevention of more severe skin issues. Consistent monitoring is key to maintaining skin health.

Question 103: Which ethical principle underlies a patient's right to refuse cancer treatment, including life-sustaining measures?

Autonomy (Correct answer)
Non-maleficence
Beneficence
Justice

Correct answer: Autonomy

Autonomy is the ethical principle affirming patients' right to make informed decisions about their own care, including refusal of treatment.

Question 104: A patient with SVC syndrome presents with facial swelling, plethora, and dyspnea. The priority nursing intervention is:

Restrict IV fluids to prevent fluid overload
Position the patient flat with legs elevated
Administer aggressive diuretic therapy immediately
Elevate the head of the bed to 45 degrees and administer oxygen (Correct answer)

Correct answer: Elevate the head of the bed to 45 degrees and administer oxygen

Elevating the head reduces venous pressure in the upper body and supplemental oxygen addresses hypoxia in SVC syndrome.

Question 105: The Philadelphia chromosome, resulting from a translocation between chromosomes 9 and 22, is the hallmark of which leukemia?

Acute lymphoblastic leukemia
Chronic myeloid leukemia (CML) (Correct answer)
Chronic lymphocytic leukemia
Hairy cell leukemia

Correct answer: Chronic myeloid leukemia (CML)

The t(9;22) translocation creates the BCR-ABL fusion gene, which drives CML and is targeted by imatinib.

Question 106: Reed-Sternberg cells are pathognomonic for which lymphoma type?

Mantle cell lymphoma
Diffuse large B-cell lymphoma
Hodgkin lymphoma (Correct answer)
Follicular lymphoma

Correct answer: Hodgkin lymphoma

Large binucleated Reed-Sternberg cells with prominent owl-eye nucleoli are the defining histologic feature of Hodgkin lymphoma.

Question 107: What cultural considerations should oncology nurses address in patient education?

The patient's employment status
Only dietary restrictions
The patient's level of formal education
Language preferences, health beliefs, decision-making practices, and spiritual needs (Correct answer)

Correct answer: Language preferences, health beliefs, decision-making practices, and spiritual needs

Culturally competent education considers the patient's language and literacy, cultural health beliefs and practices, family roles in decision-making, spiritual and religious considerations, and preferred communication styles.

Question 108: What is the recommended action if the stoma retracts below skin level?

Use a flat barrier
Switch to a convex barrier (Correct answer)
Apply powder only
Discontinue pouch use

Correct answer: Switch to a convex barrier

If a stoma retracts below skin level, a convex skin barrier is recommended. Convex barriers have a dome shape that gently presses into the peristomal skin, pushing the stoma outward and creating a better seal. This helps to prevent effluent from seeping under the barrier and irritating the skin, which is a common problem with retracted stomas.

Question 109: Which patient behavior is linked to higher appliance failure, according to clinical observations?

Routine exercise
Strict adherence to diet
Hydration maintenance
Inconsistent appliance changes (Correct answer)

Correct answer: Inconsistent appliance changes

Inconsistent appliance changes are strongly linked to higher rates of appliance failure, including leakage and skin irritation. When appliances are not changed regularly, the adhesive can degrade, the barrier can erode, and the risk of stoma output contacting the skin significantly increases, leading to complications. Adhering to recommended change schedules is vital for optimal care.

Question 110: Which statement accurately describes the timing of breast reconstruction surgery following mastectomy for breast cancer?

Reconstruction may be performed immediately at mastectomy or delayed, depending on patient preference and adjuvant treatment needs (Correct answer)
Only implant-based reconstruction is suitable following total mastectomy
Radiation therapy after mastectomy has no significant impact on reconstructive outcomes
Reconstruction must always be performed immediately at the time of mastectomy

Correct answer: Reconstruction may be performed immediately at mastectomy or delayed, depending on patient preference and adjuvant treatment needs

Breast reconstruction can be immediate (at the time of mastectomy) or delayed; the decision depends on patient preference, need for postmastectomy radiation, and overall oncologic treatment planning.

Question 111: Which of the following is a common complication of ostomies?

Joint dislocation
Peristomal skin irritation (Correct answer)
Nasal congestion
Tooth decay

Correct answer: Peristomal skin irritation

Peristomal skin irritation is a very common complication for ostomy patients, occurring when the skin around the stoma becomes inflamed or damaged. This can be due to exposure to stoma output, adhesive trauma, or an improperly fitting appliance. COCNs are trained to prevent and manage this issue through proper skin care and appliance selection.

Question 112: Which of the following best describes a healthy stoma?

Pale and dry
Moist and pink (Correct answer)
Dark and sunken
Blue and crusted

Correct answer: Moist and pink

A healthy stoma should appear moist, shiny, and pink or beefy red, similar to the mucous membrane inside the mouth. This indicates good blood supply and tissue viability. Any deviation, such as paleness, dryness, or a dark/blue color, could signal complications and requires further assessment.

Question 113: A patient is undergoing sentinel lymph node biopsy for breast cancer. Which statement best explains the purpose of this procedure?

To remove all axillary lymph nodes for comprehensive staging
To identify the first lymph node(s) receiving drainage from the primary tumor (Correct answer)
To stage distant metastasis throughout the body
To inject chemotherapy directly into the lymphatic channels

Correct answer: To identify the first lymph node(s) receiving drainage from the primary tumor

Sentinel lymph node biopsy identifies the first draining lymph node(s) from the primary tumor; if these are cancer-free, further axillary dissection is often avoided.

Question 114: Which finding on a peripheral blood smear is characteristic of chronic myeloid leukemia (CML)?

Left shift with cells at all stages of myeloid maturation (Correct answer)
Auer rods
Smudge cells
Blast crisis only

Correct answer: Left shift with cells at all stages of myeloid maturation

Head and neck radiation commonly causes oral mucositis, xerostomia, dysphagia, and taste changes, making regular oral assessment, swallowing evaluation, and nutritional monitoring essential nursing responsibilities.

Question 119: Which sign is associated with hypocalcemia seen in tumor lysis syndrome when a blood pressure cuff causes carpal spasm?

Chvostek sign
Trousseau sign (Correct answer)
Kernig sign
Cullen sign

Correct answer: Trousseau sign

Trousseau sign is carpal spasm elicited by inflating a BP cuff above systolic pressure, indicating hypocalcemia-induced neuromuscular irritability.

Question 120: Which material is typically used in ostomy skin barriers?

Rubber latex
Hydrocolloid (Correct answer)
Paper tape
Silicone sealant

Correct answer: Hydrocolloid

Hydrocolloid is the most common material used in ostomy skin barriers due to its excellent adhesive properties and ability to absorb moisture. This material protects the peristomal skin from effluent, promotes a secure seal, and can even help heal irritated skin. Its flexibility and skin-friendly nature make it ideal for long-term wear.
