Pediatric HESI Quizlet

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.

Correct Answer: B

Rationale: In cystic fibrosis, thick mucus obstructs the airways, making it difficult to clear from the lungs. Cough suppressants can help reduce the discomfort associated with persistent coughing, allowing the child to cough more effectively to clear the mucus, thus promoting pulmonary function. Chest physiotherapy, not exercise, helps mobilize the mucus. Oxygen therapy may be needed but is not the most important for promoting pulmonary function in this case.

Correct Answer: D

Rationale: In cases of digoxin toxicity, IV digoxin immune fab (Digibind) is the antidote and should be administered first to counteract the effects of digoxin poisoning. This intervention is crucial in managing digoxin overdose and should be initiated promptly to improve patient outcomes. Activated charcoal and gastric lavage are not effective in treating digoxin poisoning and may not be beneficial at this stage. While obtaining an electrocardiogram is important to assess cardiac function, administering the antidote should take precedence to address the immediate life-threatening effects of digoxin toxicity.

Correct Answer: D

Rationale: Severe skin breakdown in the diaper area is a significant finding indicating a potential health issue that needs immediate attention. It may be a sign of a skin condition, such as a diaper rash, which can cause discomfort and pain for the infant. Addressing this concern promptly is crucial to prevent further complications and ensure the baby's well-being. The other choices may also be important in assessing the overall situation of the family, but in terms of immediate care for the infant, the severe skin breakdown takes priority.

Correct Answer: B

Rationale: The correct answer is explaining the association between drinking soda and dental caries. Soda consumption can lead to tooth decay and cavities, so it is crucial to educate the mother about this to prevent dental issues in the child.
