Nursing Elites

1. The nurse is conducting an admission assessment of an 11-month-old infant with CHF who is scheduled for repair of restenosis of coarction of the aorta that was repaired 4 days after birth. Findings include blood pressure higher in the arms than the lower extremities, pounding brachial pulses, and slightly palpable femoral pulses. What pathophysiologic mechanisms support these findings?

• A. The aortic semilunar valve obstructs blood flow into the systemic circulation
• B. The lumen of the aorta reduces the volume of the blood flow to the lower extremities
• C. The pulmonic valve prevents adequate blood volume into the pulmonary circulation
• D. An opening in the atrial septum causes a murmur due to a turbulent left-to-right shunt

Correct answer: B

Rationale: The correct answer is B. Coarctation of the aorta causes narrowing of the aorta, reducing blood flow to the lower extremities. This narrowing results in higher blood pressure in the arms compared to the lower extremities, along with stronger brachial pulses and slightly palpable femoral pulses. Choices A, C, and D are incorrect because they do not align with the pathophysiological mechanism of coarctation of the aorta, which specifically leads to reduced blood flow to the lower extremities.

2. A 6-year-old boy with bronchial asthma takes the beta-adrenergic agonist albuterol (Proventil). The child’s mother tells the nurse that she uses this medication to open her son’s airway when he is having trouble breathing. What is the nurse’s best response?

• A. Recommend that the mother bring the child in for immediate evaluation
• B. Advise the mother that overuse of the drug may cause chronic bronchitis
• C. Assure the mother that she is using the medication correctly
• D. Confirm that the medication helps to reduce airway inflammation

Correct answer: C

Rationale: The correct response is to assure the mother that she is using the medication correctly. Albuterol is a beta-adrenergic agonist that helps open the airways during an asthma attack. By reassuring the mother, the nurse reinforces the correct usage of the medication, which is crucial in managing the child's asthma symptoms effectively. Option A is incorrect because immediate evaluation may not be necessary if the child's symptoms are being managed effectively with albuterol. Option B is incorrect as chronic bronchitis is not typically associated with the overuse of albuterol. Option D is incorrect as albuterol primarily acts as a bronchodilator and does not directly reduce airway inflammation.

3. The nurse is assessing a 6-month-old infant. Which response requires further evaluation by the nurse?

• A. Has doubled birth weight.
• B. Turns head to locate sound.
• C. Plays peek-a-boo.
• D. Demonstrates startle reflex.

Correct answer: D

Rationale: At 6 months old, the startle reflex should diminish, so its persistence warrants further evaluation by the nurse. Choices A, B, and C are appropriate developmental milestones for a 6-month-old infant. By 6 months, infants typically double their birth weight, exhibit localization of sound by turning their head, and engage in interactive play like peek-a-boo.

4. The mother calls the clinic and tells the practical nurse (PN) that her child cannot swallow a prescribed tablet that was dispensed by the local pharmacy as a whole tablet. How should the PN respond?

• A. You can crush the tablet and mix it with food.
• B. You should not force the child to swallow the tablets by holding her nose closed.
• C. If a liquid form is available, the pharmacist can be contacted for a prescription change.
• D. Do not advise the child to chew the tablet if she cannot swallow it.

Correct answer: C

Rationale: When a child is unable to swallow a tablet, the appropriate response is to consider if a liquid form of the medication is available. This is a safer and more effective alternative than forcing the child to swallow or chew the tablet. Contacting the pharmacist for a prescription change can provide a suitable solution that ensures the child receives the medication in a more manageable form. Choices A, B, and D are incorrect because crushing the tablet and mixing it with food may alter the medication's effectiveness or taste, forcing the child to swallow or holding her nose closed can be distressing and ineffective, and advising the child to chew the tablet is not recommended as an alternative to swallowing it.

5. The nurse is caring for a 4-year-old child who has been diagnosed with measles. Which intervention should the nurse implement to prevent the spread of infection?

• A. Administer antipyretics as prescribed
• B. Place the child in airborne isolation
• C. Encourage fluid intake
• D. Teach the parents about hand hygiene

Correct answer: B

Rationale: Measles is an airborne infection, so placing the child in airborne isolation is crucial to prevent the spread of the virus to others. Airborne isolation precautions help contain infectious respiratory droplets and reduce the risk of transmission to healthcare workers, other patients, and visitors. Administering antipyretics, encouraging fluid intake, and teaching parents about hand hygiene are important aspects of care but do not directly address the prevention of the spread of measles, which requires airborne precautions.
