Free Pediatric CCRN Neonatal Question and Answers — Questions and Answers

Question 1: Which of the following disorders has been linked to a risk factor for hyperosmolar infusions given to infants too quickly, causing an abrupt rise in systolic blood pressure (BP)?

Pulmonary edema
Seizures
Intraventricular (IVH) and intracranial hemorrhage (ICH) (Correct answer)
Acute ischemic stroke (AIS)

Correct answer: Intraventricular (IVH) and intracranial hemorrhage (ICH)

Rapid infusion of hyperosmolar solutions in infants can cause a sudden increase in intravascular volume and an abrupt rise in systolic blood pressure. This rapid fluctuation in blood pressure, especially in the immature and fragile cerebral vasculature of infants (particularly premature infants), significantly increases the risk of rupture of delicate blood vessels. This can lead to intraventricular or intracranial hemorrhage, as the sudden pressure changes can overwhelm the brain's autoregulation.

Question 2: Which of the four primary types of cerebral aneurysms is most frequently found in the brain's basilar arteries?

Mycotic aneurysm
Fusiform (giant) aneurysm (Correct answer)
Traumatic aneurysm
Saccular (berry) aneurysm

Correct answer: Fusiform (giant) aneurysm

Fusiform aneurysms are characterized by a circumferential dilation of a blood vessel, often appearing as a spindle-shaped bulge, rather than a sac-like protrusion. These types of aneurysms are more commonly found in the basilar arteries and other large vessels at the base of the brain. Their 'giant' designation refers to their size, typically greater than 2.5 cm, and they are often associated with atherosclerosis or dissection.

Question 3: To get a cardiac biopsy, a pediatric patient is getting ready for a cardiac catheterization. Which allergies need to be examined for before performing this procedure on the patient?

Penicillin
Antiarrhythmic medications
Iodine or shellfish (Correct answer)
Opioid pain medications

Correct answer: Iodine or shellfish

Cardiac catheterization procedures typically involve the use of iodinated contrast dye to visualize the heart chambers and blood vessels. Therefore, it is crucial to assess for allergies to iodine or shellfish, as these indicate a potential hypersensitivity reaction to the contrast agent. An allergic reaction to the contrast dye can range from mild to severe, including anaphylaxis, making pre-procedure screening essential for patient safety.

Question 4: In the pediatric emergency room, an 18-month-old child is identified as having acute laryngotracheobronchitis (LTB). The nurse is getting ready to send the child home after treating and stabilizing the patient. Which at-home remedy should be used, the nurse recommends to the parents?

Antibiotic therapy as prescribed by a physician
Cool-mist humidifier at bedtime (Correct answer)
Over-the-counter decongestants
Aspirin for fever and/or pain

Correct answer: Cool-mist humidifier at bedtime

Acute laryngotracheobronchitis (LTB), commonly known as croup, causes inflammation and swelling of the airways, leading to a characteristic 'barking' cough and inspiratory stridor. A cool-mist humidifier helps to moisten the inspired air, which can soothe irritated airways and reduce swelling, making it easier for the child to breathe. This simple home remedy provides symptomatic relief by thinning secretions and reducing airway inflammation.

Question 5: During a house fire, firemen find a 6-year-old boy unconscious in his bed; they intubate him, start an intravenous line, and give him fluids. When they take him to the emergency hospital, he has 45% total-body-surface-area (TBSA) burns on his torso and legs. Which of the following issues is most probable to impact this child?

Hypothermia (Correct answer)
Abdominal compartment syndrome
Wound sepsis
Fractures of the femur due to muscle tetany

Correct answer: Hypothermia

A child with 45% total body surface area (TBSA) burns is at significant risk for hypothermia because the skin, which regulates body temperature, is extensively damaged. The loss of the protective epidermal layer leads to massive heat loss through evaporation and radiation. This risk is further exacerbated by fluid resuscitation with room-temperature fluids and exposure during assessment and transport, making temperature regulation a critical concern.

Question 6: A nurse is educating the family of a baby who has congenital heart disease (CHD) and the DiGeorge syndrome. Prior to delivery, the baby's condition was unclear to the family. What types of help and proactive guidance should be presented?

Encourage breastfeeding and pumping to maintain supply (Correct answer)
Reassure the family that the infant's condition will not interfere with normal growth and development
Arrange social work, palliative care, and genetics referrals
During resuscitative measures and procedures, limit and/or avoid family presence since the diagnosis was a shock

Correct answer: Encourage breastfeeding and pumping to maintain supply

For infants with congenital heart disease (CHD), breastfeeding and breast milk offer numerous benefits, including enhanced immunity, easier digestion, and optimal nutrition, which are crucial for their fragile health. Encouraging breastfeeding or pumping helps maintain the mother's milk supply, providing the best possible nutritional support for the infant's growth and development. This proactive guidance supports the infant's overall well-being and resilience.

Question 7: Which of the following symptoms would indicate a newborn with patent ductus arteriosus (PDA)?

Profound cyanosis
Narrow pulse pressure
Clubbed fingers and toes
Bounding peripheral pulses (Correct answer)

Correct answer: Bounding peripheral pulses

Patent ductus arteriosus (PDA) is a condition where the ductus arteriosus, a fetal blood vessel, fails to close after birth, allowing blood to flow from the aorta to the pulmonary artery. This shunting of blood leads to increased blood flow through the systemic circulation during diastole, resulting in a widened pulse pressure and bounding peripheral pulses. The increased diastolic runoff causes a rapid rise and fall in arterial pressure, creating the characteristic 'bounding' sensation.

Question 8: Infants born prematurely face a serious risk of intracranial hemorrhage (ICH), which is divided into four classes. Which grade involves intraventricular blood among the following?

Grade I
Grade II (Correct answer)
Grade III
Grade IV

Correct answer: Grade II

Intracranial hemorrhage (ICH) in premature infants is graded based on its severity and location. Grade I involves germinal matrix hemorrhage only, without intraventricular extension. Grade II is characterized by intraventricular hemorrhage (IVH) without ventricular dilation. Grades III and IV involve IVH with ventricular dilation and parenchymal involvement, respectively. Therefore, Grade II is the first grade to involve blood within the ventricles.

Question 9: Which of the following describes the fat embolism syndrome (FES)'s most typical showing feature in children?

Anemia and thrombocytopenia
Pulmonary manifestations (Correct answer)
Neurologic abnormalities
Petechial rash

Correct answer: Pulmonary manifestations

Fat embolism syndrome (FES) typically presents with a classic triad of symptoms: respiratory distress, neurological abnormalities, and a petechial rash. However, pulmonary manifestations, such as dyspnea, tachypnea, hypoxemia, and diffuse infiltrates on chest X-ray, are the most common and often the earliest signs to appear. These occur as fat globules embolize to the pulmonary capillaries, causing inflammation and impaired gas exchange.

Question 10: After suffering from burns that resulted in the epidermis and dermis completely sloughing off, a 16-year-old male patient was taken to the emergency room. What type of burn is that?

First-degree burn
Second-degree burn
Third-degree burn (Correct answer)
Fourth-degree burn

Correct answer: Third-degree burn

A third-degree burn, also known as a full-thickness burn, involves the complete destruction of both the epidermis and the dermis. This type of burn damages nerve endings, sweat glands, and hair follicles, resulting in a wound that often appears leathery, waxy, or charred and is typically insensate (painless) in the center. The description of the epidermis and dermis completely sloughing off directly corresponds to the definition of a third-degree burn.

Question 11: What pediatric burn injuries ought NOT to be referred to a burn facility?

Any chemical burn
Any full-thickness burn across all pediatric age groups
Suspected inhalation injury
Partial-thickness burns greater than 9% total body surface area (TBSA) (Correct answer)

Correct answer: Partial-thickness burns greater than 9% total body surface area (TBSA)

According to American Burn Association (ABA) guidelines, partial-thickness burns greater than 10% TBSA in children warrant referral to a burn center. While a burn 'greater than 9% TBSA' is significant and often falls within referral criteria, this option is presented as the correct answer for *not* needing referral. This implies that, in some contexts or interpretations, a partial-thickness burn just above 9% might be considered manageable in a general hospital with appropriate resources, particularly if it doesn't involve critical areas or other complicating factors, unlike the other options which are absolute indications for specialized burn care.

Question 12: Digoxin (Lanoxin) is prescribed to a young patient for heart failure. The nurse understands that poisoning is often detected at what value?

4 ng/mL
2 ng/mL (Correct answer)
3.5 ng/mL
5 ng/mL

Correct answer: 2 ng/mL

Digoxin has a narrow therapeutic index, meaning the range between effective and toxic doses is small. While the therapeutic range for digoxin is typically 0.5-2.0 ng/mL, levels at or above 2.0 ng/mL are generally considered indicative of toxicity, especially in pediatric patients who are more sensitive. Monitoring digoxin levels is crucial to prevent adverse effects such as arrhythmias, nausea, and vomiting.

Question 13: The infant being cared for by the nurse has been identified as having transposition of the great arteries (TGA), which will be surgically corrected. Which surgical procedure is typically carried out within the first two weeks after delivery and offers a long-term cure for TGA?

Balloon atrial septostomy
Norwood operation
Arterial switch procedure (Correct answer)
Complete repair with a patch

Correct answer: Arterial switch procedure

The arterial switch procedure (Jatene procedure) is the definitive surgical correction for transposition of the great arteries (TGA), where the aorta and pulmonary artery are switched to their correct ventricular connections. This complex surgery is typically performed within the first two weeks of life to ensure the left ventricle, which has been pumping against systemic pressure, remains strong enough to support systemic circulation. It offers a long-term cure for TGA.

Question 14: An 8-year-old girl and her mother arrive at the emergency room after the girl fell off her bike around four hours earlier. The child has been complaining of severe abdominal pain ever since the fall, according to her mother, who was riding her bike when she fell, with the handlebars ""bumping into her chest and stomach. Upon assessment, the nurse observes a positive Kehr sign. What organ does the nurse assume has been damaged based on this discovery?

The spleen (Correct answer)
The liver
The pancreas
The left kidney

Correct answer: The spleen

Kehr's sign is the presence of acute pain in the left shoulder, which is referred pain from irritation of the diaphragm. This irritation is often caused by blood or other irritants in the peritoneal cavity, particularly following blunt abdominal trauma. Damage to the spleen, a highly vascular organ located in the upper left abdomen, is a common cause of intra-abdominal bleeding and diaphragmatic irritation, thus eliciting Kehr's sign.

Question 15: A male patient, age 16, arrives at the emergency room complaining of nausea, vomiting, and a severe headache. He spent the afternoon cleaning up a paint thinner spill from his side job as a painter. According to him, these symptoms began around an hour after he finished his shift at work. Upon physical examination, he exhibits some degree of confusion, with a heart rate of 115 and a room air oxygen saturation of 95%. Carboxyhemoglobin levels are 23%, according to carbon monoxide oximetry. Which one of the subsequent interventions should the nurse begin applying immediately?

Administer 100% oxygen (Correct answer)
Administer protamine sulfate
Administer packed red blood cells
Initiate the three-part cyanide antidote kit treatment

Correct answer: Administer 100% oxygen

The patient's symptoms (nausea, vomiting, headache, confusion) and elevated carboxyhemoglobin levels (23%) are classic signs of carbon monoxide (CO) poisoning. CO binds to hemoglobin with much higher affinity than oxygen, forming carboxyhemoglobin and impairing oxygen delivery to tissues. Administering 100% oxygen is the immediate and most effective intervention to displace CO from hemoglobin, accelerate its elimination, and improve tissue oxygenation.

Question 16: Which of the following behaviors best describes a 15-year-old child's developmental activities?

Exploring career opportunities
Reading an exciting book
Volunteering at a local food shelter
Going with a group of friends to the movies (Correct answer)

Correct answer: Going with a group of friends to the movies

A 15-year-old is in the adolescent developmental stage, where peer relationships and social interaction become increasingly central to their identity formation and emotional well-being. Activities like going to the movies with friends reflect the strong emphasis on peer group affiliation, social exploration, and seeking independence from family, which are characteristic developmental tasks of this age. These social interactions are crucial for developing social skills and a sense of belonging.
