Correct Answer: D

Rationale: Toddlers subjected to prolonged hospitalization with limited parental visits often exhibit a limited emotional response to the environment. This behavior is a common coping mechanism in young children facing such situations. While cheerful interactions with staff members (choice A) may occur occasionally, the overall response tends to be subdued. Indications of sadness throughout the day (choice B) and excessive crying when parents are not present (choice C) are less typical in this scenario, as the child may have learned to suppress emotions due to the challenging circumstances.

Correct Answer: D

Rationale: The correct answer is D. Infants have a higher extracellular fluid requirement per unit of body weight, making them more susceptible to dehydration and electrolyte imbalances during illnesses such as diarrhea. Choice A is incorrect because cellular metabolism being unstable is not the primary explanation for the symptoms described. Choice B is incorrect as the proportion of water in the body alone does not fully explain the increased risk of dehydration in infants. Choice C is incorrect because while renal function is immature in children, it is not the most relevant factor in this scenario compared to the increased fluid requirements.

Correct Answer: A

Rationale: The primary goal of therapy during the acute phase of Kawasaki disease is to prevent coronary artery aneurysms, which are a serious complication of this condition. Coronary artery aneurysms can lead to long-term cardiovascular issues, making prevention crucial. While reducing fever and improving cardiac function are important aspects of managing Kawasaki disease, the primary focus in the acute phase is on preventing coronary artery aneurysms. Dehydration prevention is also essential but not the primary goal during the acute phase of this disease.

Correct Answer: D

Rationale: Toddlers subjected to prolonged hospitalization with limited parental visits usually exhibit a limited emotional response to the environment. This behavior can be a coping mechanism for the child in dealing with the separation from their primary caregivers. The child might not show the same level of engagement or emotional expression as they would if their parents were present. Choices A, B, and C are less likely because the child's emotional response is typically more subdued and withdrawn in such circumstances, rather than being cheerful, consistently sad, or excessively crying.

Correct Answer: A

Rationale: The priority nursing intervention when caring for a child with cystic fibrosis is administering pancreatic enzymes. Cystic fibrosis is a genetic disorder that affects the digestive and respiratory systems. Administering pancreatic enzymes is crucial in aiding digestion as patients with cystic fibrosis often have pancreatic insufficiency. While providing respiratory therapy and encouraging physical activity are important aspects of care for individuals with cystic fibrosis, administering pancreatic enzymes takes precedence in addressing the malabsorption issues associated with the condition. Encouraging frequent handwashing is also essential in infection control, but it is not the priority intervention specifically related to managing cystic fibrosis.
