Mixed Deck — All LVN Topics Flashcards

Which growth measurement is most reflective of long-term nutritional status in children?

Answer: Length/height for age

Height/length for age reflects chronic nutritional status because stunting (short stature) results from prolonged nutritional deficiency.

Which route of administration is used for vaccines?

Answer: Intramuscular

Intramuscular (IM) injection is the primary route for administering many vaccines because it delivers the antigen into muscle tissue, which has a rich blood supply and immune cells. This allows for effective absorption and a robust immune response, leading to better vaccine efficacy.

A patient has a DNR order on file. The patient goes into cardiac arrest and a family member demands that CPR be started. The LVN should:

Answer: Honor the DNR order and provide comfort measures

A valid DNR order reflects the patient's wishes and must be honored even over family objections; the legal document takes precedence.

A toddler swallowed a button battery 30 minutes ago. Which nursing action is most urgent?

Answer: Prepare for emergency endoscopic removal

Button batteries lodged in the esophagus can cause tissue necrosis within 2 hours; emergency endoscopic removal is required.

A nurse notes that a surgical wound has separated along the suture line with intestines visible through the opening. This is termed:

Answer: Evisceration

Evisceration is the protrusion of internal organs through a wound opening and requires emergency intervention.

A newborn has an Apgar score of 4 at 1 minute. What is the priority nursing action?

Answer: Begin positive pressure ventilation

An Apgar score of 4–6 indicates moderate distress and requires stimulation and positive pressure ventilation if breathing is inadequate.

Which patient is the most appropriate candidate for protective (reverse) isolation?

Answer: A neutropenic patient receiving chemotherapy with ANC < 500

Protective isolation shields severely immunocompromised patients (like those with severe neutropenia) from environmental pathogens and staff/visitor organisms.

Which mineral is essential for insulin synthesis and glucose metabolism?

Answer: Zinc

Zinc is required for the synthesis, storage, and secretion of insulin by pancreatic beta cells.

Which action best prevents ventilator-associated pneumonia (VAP)?

Answer: Elevating the head of the bed to 30–45 degrees

Elevating the head of the bed 30–45 degrees reduces gastric reflux and aspiration of oral secretions into the lungs, the primary mechanism of VAP.

A 2-year-old with intussusception is most likely to present with which classic symptom pattern?

Answer: Sudden intermittent abdominal pain, vomiting, and currant jelly stools

Intussusception classically presents with sudden episodic colicky pain, vomiting, and currant jelly stools (blood mixed with mucus).

Which behavior by a long-term care staff member constitutes elder abuse?

Answer: Yelling at a resident to hurry up during morning care

Yelling at a resident is psychological/emotional abuse, which is a form of elder abuse and violates residents' rights.

An LVN administers the wrong medication due to a misread order. Which action is legally required after notifying the supervisor?

Answer: Complete an incident/variance report documenting the error

Incident reports are a legal requirement to document medication errors and initiate follow-up for patient safety.

How should LVN professionals handle confidential information related to leadership & team collaboration?

Answer: Follow established protocols for data protection, access control, and disclosure in accordance with applicable regulations

Confidential information must be handled according to established protocols, regulatory requirements, and professional ethics standards, including proper access control and disclosure procedures.

Which observation indicates a therapeutic response to a bronchodilator like albuterol?

Answer: Decreased respiratory rate and improved breath sounds

A therapeutic response to albuterol includes improved airflow, indicated by decreased respiratory rate and clearer breath sounds.

Which complication is MOST associated with excessive vitamin A supplementation during pregnancy?

Answer: Fetal teratogenicity and birth defects

Excessive vitamin A (especially preformed retinol) is teratogenic and can cause serious fetal abnormalities, particularly in the first trimester.

A medication order reads: 'Amoxicillin 500 mg PO TID x 10 days.' How many total doses will the patient receive?

Answer: 30 doses

TID means three times daily; 3 doses/day × 10 days = 30 total doses.

An LVN notices signs of nurse burnout in a team member. The most helpful initial response is to:

Answer: Privately express concern and encourage the nurse to seek support resources

Expressing concern privately and directing a colleague to support resources is the most supportive and professional response.

A breastfeeding mother asks the LVN about calcium needs. The recommended daily calcium intake for a lactating woman is:

Answer: 1,000 mg

The recommended dietary allowance for calcium in lactating women is 1,000 mg per day, the same as for non-pregnant adult women.

A tunneling wound is documented as having a tunnel at 3 o'clock position, 4 cm deep. Using the clock face method, where is 3 o'clock located relative to the patient?

Answer: Toward the patient's right side

Using the clock face with 12 o'clock toward the patient's head, 3 o'clock corresponds to the patient's right side.

Which IV fluid is considered isotonic and is most commonly used for fluid resuscitation?

Answer: 0.9% NaCl (Normal Saline)

0.9% NaCl (Normal Saline) is isotonic and remains in the vascular space, making it the standard choice for fluid resuscitation.
