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: Tachypnea is an early sign of congestive heart failure that nurses should recognize. Tachypnea refers to rapid breathing, which can be an indication of the body's attempt to compensate for decreased cardiac output in congestive heart failure. Bradycardia (choice B) is a slow heart rate and is not typically associated with congestive heart failure. Inability to sweat (choice C) and increased urinary output (choice D) are not specific early signs of congestive heart failure and are not typically recognized as such.

Correct Answer: C

Rationale: Tetralogy of Fallot is characterized by a combination of four specific cardiac defects: right ventricular hypertrophy, ventricular septal defect, pulmonic stenosis, and overriding aorta. Choice A is incorrect as it includes mitral valve stenosis, which is not typically part of tetralogy of Fallot. Choice B describes transposition of the great arteries rather than tetralogy of Fallot. Choice D includes an atrial septal defect, which is not part of the classic presentation of tetralogy of Fallot.

Correct Answer: B

Rationale: The priority nursing intervention when caring for a child with nephrotic syndrome is to monitor urine output. This is essential to assess kidney function and evaluate the effectiveness of treatment. Administering diuretics (Choice A) may be a part of the treatment plan but should not be the priority over monitoring urine output. Administering corticosteroids (Choice C) is a common treatment for nephrotic syndrome, but monitoring urine output takes precedence. Restricting fluid intake (Choice D) may be necessary in some cases, but it is not the priority intervention compared to monitoring urine output.

Correct Answer: C

Rationale: In type 1 diabetes, extra snacks are needed before exercise to prevent hypoglycemia. It is important to provide additional carbohydrates to maintain blood glucose levels during physical activity. Choices A, B, and D are incorrect. Exercise typically lowers blood glucose levels in individuals with diabetes; however, proper management and adjustments in insulin and food intake are necessary to prevent hypoglycemia. Exercise should not be restricted in individuals with type 1 diabetes but should be planned in coordination with healthcare providers to ensure safety and optimal glucose control. While some individuals may need adjustments in insulin dosages during exercise, the general statement that extra insulin is required during exercise in type 1 diabetes is not accurate.
