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 coarctation 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 findings are consistent with coarctation of the aorta, where narrowing of the aorta leads to decreased blood flow to the lower extremities. This results in higher blood pressure in the arms compared to the lower extremities, pounding brachial pulses, and slightly palpable femoral pulses. Choices A, C, and D are incorrect because they do not align with the pathophysiological mechanisms of coarctation of the aorta, which specifically involves narrowing of the aortic lumen reducing blood flow to the lower extremities.

2. When developing a behavior modification program for an extremely aggressive 10-year-old boy, what should the nurse do first?

• A. Identify what activities, foods, and toys the child enjoys
• B. Assess the child's previous reactions to punishment
• C. Offer the child positive feedback
• D. Involve other children on the unit in describing the token system

Correct answer: A

Rationale: The first step in developing a behavior modification program for an extremely aggressive 10-year-old boy is to identify what activities, foods, and toys the child enjoys. Understanding the child's motivations is crucial in creating an effective behavior modification plan tailored to his interests and preferences, which can help in positively reinforcing desired behaviors.

3. The healthcare provider is assessing an infant with pyloric stenosis. Which pathophysiological mechanism is the most likely consequence of this infant's clinical picture?

• A. Metabolic alkalosis.
• B. Respiratory acidosis.
• C. Metabolic acidosis.
• D. Respiratory alkalosis.

Correct answer: A

Rationale: Pyloric stenosis leads to obstruction at the outlet of the stomach, causing frequent vomiting and loss of stomach acids. This results in a loss of hydrochloric acid and hydrogen ions, leading to metabolic alkalosis due to an increase in serum bicarbonate levels. Therefore, the correct answer is metabolic alkalosis. Choice B, respiratory acidosis, is incorrect as it is not typically associated with pyloric stenosis. Choice C, metabolic acidosis, is incorrect because the loss of stomach acids in pyloric stenosis leads to metabolic alkalosis, not acidosis. Choice D, respiratory alkalosis, is also incorrect as it is not the usual consequence of pyloric stenosis.

4. The caregiver is caring for a 3-year-old child with a diagnosis of gastroenteritis. The child has had several episodes of vomiting and diarrhea over the past 24 hours. What is the caregiver's priority assessment?

• A. Monitor the child's weight
• B. Assess the child's hydration status
• C. Evaluate the child's nutritional intake
• D. Check the child's temperature

Correct answer: B

Rationale: The correct answer is B: Assess the child's hydration status. In children with gastroenteritis, assessing hydration status is crucial as they are at risk of dehydration due to vomiting and diarrhea. Monitoring hydration helps prevent complications and guides appropriate interventions to maintain the child's fluid balance. Monitoring the child's weight (Choice A) is not the priority in this situation compared to assessing hydration status. Evaluating nutritional intake (Choice C) is important but not the priority when the child is at risk of dehydration. Checking the child's temperature (Choice D) is relevant but not the priority over assessing hydration status in a child with gastroenteritis.

5. The nurse is preparing to administer an immunization to a 5-year-old child. The parent asks if the vaccine can be given in a different way because the child is afraid of needles. What is the nurse’s best response?

• A. We can apply a numbing cream before the injection
• B. There is no other way to administer this vaccine
• C. We can give the vaccine as a nasal spray
• D. We can skip the vaccine if the child is too afraid

Correct answer: C

Rationale: Administering the vaccine as a nasal spray provides an alternative method of delivery that avoids the use of needles, addressing the child's fear while ensuring immunization. Nasal sprays are effective for certain vaccines and can be a suitable option in this scenario. Choice A is not the best response as it only addresses pain management but does not eliminate the use of needles. Choice B is incorrect as there are alternative delivery methods like nasal sprays. Choice D is incorrect as skipping the vaccine would leave the child unprotected and is not a recommended course of action.
