Pediatric HESI 2023

Correct Answer: A

Rationale: The correct answer is A: Rest. When a child is admitted to the hospital with pneumonia, the priority need in the nursing plan of care is to ensure adequate rest. Rest is crucial as it allows the child's body to fight the infection and recover. Choice B, Exercise, would not be appropriate as the child needs rest to conserve energy and promote healing. Choice C, Nutrition, is important for overall health but may not be the immediate priority when the child is acutely ill with pneumonia. Choice D, Elimination, is important but is not the priority need in this scenario compared to ensuring rest to aid recovery from pneumonia.

Correct Answer: C

Rationale: In pyloric stenosis, a palpable olive-like mass in the abdomen is a classic finding. This mass is due to the hypertrophied pyloric muscle. Abdominal rigidity (choice A) is associated with conditions like peritonitis, substernal retraction (choice B) is typically seen in respiratory distress, and marked distention of the lower abdomen (choice D) is more characteristic of conditions like intestinal obstruction rather than pyloric stenosis.

Correct Answer: B

Rationale: The correct answer is B. Live vaccines like MMR should not be given to immunosuppressed infants because their weakened immune systems may not handle the vaccine safely. Choice A is incorrect as delaying the MMR vaccine until the infant reaches 2 years of age does not address the issue of immunosuppression. Choice C is incorrect because administering live vaccines to an immunosuppressed individual could lead to serious complications. Choice D is incorrect as immediate action is required to prevent potential harm to the immunosuppressed infant.

Correct Answer: D

Rationale: The correct answer is D, Rheumatic fever. Rheumatic fever can develop as a complication of untreated strep throat caused by beta-hemolytic streptococcus. It is characterized by inflamed joints and can lead to serious complications such as heart infections. Tetanus (choice A) is caused by a bacterial toxin affecting the nervous system, Influenza (choice B) is a viral respiratory illness, and Scarlet fever (choice C) is also caused by streptococcus but is characterized by a sandpaper-like rash and strawberry tongue. However, in the scenario described, the nurse is most concerned about the child developing rheumatic fever due to the potential serious consequences associated with it.

Correct Answer: D

Rationale: Rheumatic fever is the most concerning illness in this case. It can develop as a complication of untreated strep throat caused by beta-hemolytic streptococcus. If not properly treated, rheumatic fever can lead to serious complications such as inflamed joints and heart infections. Tetanus is caused by a toxin produced by Clostridium tetani bacteria and is not related to the symptoms described in the scenario. Influenza is a viral respiratory illness and does not typically lead to rheumatic fever. While scarlet fever is also caused by streptococcus bacteria, in this case, the symptoms described are more indicative of rheumatic fever than scarlet fever.
