Correct Answer: C

Rationale: Administering antibiotics is a crucial nursing intervention after a tonsillectomy because it helps prevent infections, which are a common postoperative complication. Encouraging deep breathing exercises (Choice A) is also important for promoting lung expansion and preventing respiratory complications. Encouraging the child to eat (Choice B) may not be appropriate immediately after a tonsillectomy due to the risk of throat irritation and discomfort. Applying ice to the throat (Choice D) is generally not recommended post-tonsillectomy as it may cause vasoconstriction and hinder the healing process.

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 for a 5-year-old child admitted to the hospital with bacterial meningitis is to isolate the child. Isolating the child is crucial to prevent the spread of infection to others, as bacterial meningitis is highly contagious. Administering antibiotics (Choice A) is important in the treatment of bacterial meningitis, but isolating the child takes precedence to protect others. Monitoring vital signs (Choice C) and administering fluids (Choice D) are essential aspects of care for a child with meningitis but are not the priority intervention to prevent the spread of the infection.

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 as cellular metabolism instability does not directly relate to the infant's condition described. Choice B is inaccurate as the proportion of water in the body is not the primary issue causing the infant's symptoms. Choice C is incorrect as renal function being immature does not explain the sudden change in the infant's health status; it is more related to fluid balance and dehydration.

Correct Answer: D

Rationale: Promoting perianal skin integrity is crucial when caring for a young child with severe diarrhea to prevent skin breakdown from the irritation caused by frequent bowel movements. Maintaining the IV (Choice A) may be important for hydration but is not directly related to managing skin integrity. Taking daily weights (Choice B) is important for monitoring fluid balance but does not address the immediate need to prevent skin breakdown. While replacing lost calories (Choice C) is important, it is not the priority when a child is experiencing severe diarrhea and skin integrity is at risk.
