Correct Answer: A

Rationale: The priority nursing intervention for a child with leukemia receiving chemotherapy is monitoring for signs of infection. Chemotherapy can suppress the immune system, putting the child at a higher risk of developing infections. Early detection of signs of infection is crucial to prevent serious complications and initiate timely treatment. Providing nutritional support is important for overall health but is not the priority when the child is at risk of infection. Monitoring for signs of bleeding is essential, but infection surveillance takes precedence due to the immediate threat it poses to the child's health. Monitoring for signs of pain is important for comfort but is not the priority over infection prevention and management.

Correct Answer: B

Rationale: The correct dietary instruction for a 2-year-old child with GERD is to avoid gluten. Gluten is a protein found in wheat, barley, and rye that can worsen GERD symptoms. Avoiding gluten can help reduce inflammation and discomfort in the esophagus. Choices A, C, and D are incorrect because spicy foods, high-fat foods, and dairy products can exacerbate GERD symptoms. Spicy foods can irritate the esophagus, high-fat foods delay stomach emptying leading to increased acid reflux, and dairy products can stimulate acid production, all of which can worsen GERD symptoms.

Correct Answer: B

Rationale: The correct answer is B. Tap water enemas can cause significant fluid and electrolyte imbalances, particularly in infants, making them unsafe for this age group. Choice A is incorrect because tap water enemas do not directly lead to loss of necessary nutrients. Choice C is incorrect as it focuses on emotional impact rather than physiological risks. Choice D is incorrect as shock from a sudden drop in temperature is not a common consequence of a tap water enema in this scenario.

Correct Answer: C

Rationale: In a severe asthma attack, the child is likely to develop respiratory acidosis due to impaired respirations leading to the retention of carbon dioxide, which combines with water to form carbonic acid. This results in the pH imbalance characterized by an excess of carbonic acid. Choices A, B, and D are incorrect. Metabolic alkalosis (Choice A) is not typically associated with severe asthma attacks; respiratory alkalosis (Choice B) would involve a decrease, not an increase, in carbon dioxide levels; and metabolic acidosis (Choice D) is not the primary acid-base imbalance seen in severe asthma attacks.

Correct Answer: D

Rationale: For a child with diabetes mellitus, following a specific meal plan is crucial for managing blood glucose levels effectively. This helps in maintaining stable blood sugar levels and preventing complications associated with the condition. Monitoring blood glucose levels daily and recognizing signs of hypoglycemia are also important aspects of managing diabetes; however, adherence to a specific meal plan plays a fundamental role in overall diabetes care. Administering insulin based on blood glucose levels alone is not recommended without a specific plan provided by healthcare providers.
