Nursing Elites

1. At what age is binocularity, the ability to fixate on one visual field with both eyes simultaneously, typically achieved?

• A. 1 month
• B. 3 to 4 months
• C. 6 to 8 months
• D. 12 months

Correct answer: B

Rationale: Binocularity, the ability to fixate on one visual field with both eyes simultaneously, is typically achieved by the age of 3 to 4 months. Achieving binocularity at 1 month is too early for most infants as their visual system is still developing. Similarly, 6 to 8 months and 12 months are beyond the normal age range for achieving binocularity, and delayed achievement could indicate potential issues like strabismus, which may lead to visual impairment if not addressed.

2. Which family theory explains how families react to stressful events and suggests factors that promote adaptation to these events?

• A. Interactional theory
• B. Family stress theory
• C. Erikson's psychosocial theory
• D. Developmental systems theory

Correct answer: B

Rationale: Family stress theory explains how families respond to stress and identifies factors that help families adapt to and manage stressful events effectively.

3. The nurse is teaching a parent of a 6-month-old infant with gastroesophageal reflux (GER) before discharge. What instructions should the nurse include?

• A. Elevate the head of the bed in the crib to a 90-degree angle while the infant is sleeping.
• B. Hold the infant in the prone position after a feeding.
• C. Discontinue breastfeeding so that a formula and rice cereal mixture can be used.
• D. Prescribed cimetidine (Tagamet) should be given 30 minutes before feedings.

Correct answer: D

Rationale: Cimetidine is an H2 blocker that reduces stomach acid, helping manage GER. Holding the infant in the prone position is not recommended due to the risk of SIDS. Breastfeeding should not be discontinued unless advised by a physician. Elevating the head to 90 degrees is excessive.

4. What is the most common cause of bronchiolitis in infants?

• A. Adenovirus
• B. Influenza virus
• C. Respiratory syncytial virus
• D. Parainfluenza virus

Correct answer: C

Rationale: The correct answer is C, Respiratory syncytial virus (RSV). RSV is the leading cause of bronchiolitis, a common respiratory condition in infants that results in inflammation of the small airways in the lung. It is highly contagious and can cause severe respiratory distress in young children, particularly those under 2 years old. Choice A, Adenovirus, is not the most common cause of bronchiolitis in infants. Choice B, Influenza virus, may cause respiratory infections but is not the primary cause of bronchiolitis. Choice D, Parainfluenza virus, can cause croup and other upper respiratory infections but is not the main cause of bronchiolitis in infants.

5. What is the first step in managing a child with anaphylaxis?

• A. Administer antihistamines
• B. Establish IV access
• C. Administer epinephrine
• D. Monitor vital signs

Correct answer: C

Rationale: The correct answer is to administer epinephrine. Administering epinephrine is the crucial first step in managing anaphylaxis as it helps reverse the severe allergic reaction by constricting blood vessels and relaxing airway muscles, preventing a life-threatening situation. Antihistamines (Choice A) are not the first-line treatment for anaphylaxis and should not delay the administration of epinephrine. Establishing IV access (Choice B) may be necessary but is not the initial step in managing anaphylaxis. Monitoring vital signs (Choice D) is important but should not take precedence over administering epinephrine in the acute management of anaphylaxis.
