Pediatric HESI Practice Questions

Correct Answer: C

Rationale: Circumoral cyanosis should alert the nurse to perform further assessment in a 2-month-old infant with Down syndrome. This finding may indicate cardiac or respiratory issues, such as inadequate oxygenation. Small, low-set ears and a protruding furrowed tongue are common physical characteristics associated with Down syndrome and may not necessarily warrant immediate further assessment. A flat occiput is a normal variation in infant anatomy and is not typically a cause for immediate concern in this context.

Correct Answer: B

Rationale: The correct answer is B: Signs of dehydration. Assessing for signs of dehydration is crucial in infants with hypertrophic pyloric stenosis (HPS) because they are at high risk due to frequent vomiting. Dehydration can lead to serious complications if not promptly addressed. Choices A, C, and D are not the priority assessments for HPS. While the quality of the cry can provide some information on the infant's distress level, dehydration assessment takes precedence. Coughing up feedings may not be specific to HPS, and characteristics of the stool, although important in general assessments, are not the priority in this situation.

Correct Answer: C

Rationale: A moist sterile dressing should be used to protect the exposed bladder tissue from infection and injury. Exstrophy of the bladder requires careful management to prevent complications such as infection. A loose diaper (Choice A) may not provide adequate protection or prevent infection. Dry gauze dressing (Choice B) may not be ideal as it could adhere to the exposed area and cause trauma upon removal. Petroleum jelly gauze pad (Choice D) may not be suitable as it can trap moisture and increase the risk of infection.

Correct Answer: D

Rationale: The correct answer is D: Serum immunoglobulin E (IgE) level. An elevated serum IgE level is commonly associated with atopic dermatitis, reflecting an allergic response. Choice A, erythrocyte sedimentation rate, is not typically used to diagnose atopic dermatitis. Choice B, potassium hydroxide prep, is used to identify fungal infections like ringworm, not for diagnosing atopic dermatitis. Choice C, wound culture, is performed to identify microorganisms in a wound, not to diagnose atopic dermatitis.

Correct Answer: C

Rationale: The most appropriate nursing diagnosis for a child with acute glomerulonephritis is 'Fluid volume excess related to decreased plasma filtration.' Acute glomerulonephritis is characterized by inflammation in the glomeruli, leading to decreased plasma filtration and retention of fluid. This results in fluid volume excess rather than deficit, making choice C the correct answer. Choice A is incorrect because acute glomerulonephritis is not primarily associated with a malignant process. Choice B is incorrect as the condition typically presents with fluid volume excess rather than deficit. Choice D is also incorrect as fluid accumulation in tissues and third spaces is not a typical manifestation of acute glomerulonephritis.
