Pediatric HESI 2023

Correct Answer: B

Rationale: Live vaccines, like the measles, mumps, and rubella (MMR) vaccine, should not be administered to immunosuppressed infants, such as those undergoing chemotherapy. The weakened immune system of these infants may not be able to handle live vaccines safely, potentially leading to severe complications. Therefore, it is crucial to avoid giving live vaccines like MMR to infants receiving chemotherapy. Choice A is incorrect as delaying the MMR vaccine until the infant reaches 2 years of age is not the main concern in this scenario. Choice C is incorrect because although MMR vaccination is important for disease prevention, it should not be given to immunosuppressed infants. Choice D is incorrect as immediate action is needed to prevent potential harm from live vaccines in immunosuppressed infants.

Correct Answer: A

Rationale: The correct answer is 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 for the child. Rest is crucial as it allows the child's body to fight the infection and recover. Choice B, Exercise, is incorrect as strenuous physical activity may further strain the child's respiratory system. Choice C, Nutrition, is important but providing rest takes precedence initially. Choice D, Elimination, is not the priority concern in this scenario compared to ensuring rest for recovery from pneumonia.

Correct Answer: A

Rationale: The priority nursing diagnosis for a 7-year-old boy with diabetes insipidus is deficient fluid volume related to dehydration. Diabetes insipidus leads to excessive urination and fluid loss, which can result in dehydration. This diagnosis should take precedence as restoring fluid balance is crucial in managing this condition. Choices B, C, and D are less of a priority in this case. Excess fluid volume related to edema is not typically associated with diabetes insipidus. Deficient knowledge about fluid intake and imbalanced nutrition related to excess weight may be important but addressing the dehydration and fluid volume deficit is the most critical aspect in the immediate care of a child with diabetes insipidus.

Correct Answer: C

Rationale: Peripheral edema is often the last sign of heart failure in infants and children as it indicates significant fluid retention and circulatory compromise. Tachypnea (Choice A) and tachycardia (Choice B) are early signs of heart failure due to the body's compensatory mechanisms. Periorbital edema (Choice D) can occur in heart failure but is not typically the last sign; it is more commonly associated with renal or hepatic dysfunction.

Correct Answer: B

Rationale: For a 2-year-old child, the maximum recommended amount of fluid for an isotonic enema is between 155 to 250 mL. This range is considered safe to prevent overdistension and potential harm to the child's rectum. Choices A, C, and D exceed the safe range for a 2-year-old child and can lead to complications such as bowel perforation or electrolyte imbalances.
