Correct Answer: D

Rationale: The correct answer is D. Congenital hypothyroidism in infants often leads to lethargy and difficulty staying awake due to low thyroid hormone levels. Assessing the child's ability to stay awake is crucial in identifying signs of hypothyroidism. Choices A, B, and C are incorrect because above-normal growth, being active and playful, and having healthy-looking skin are not typical manifestations of congenital hypothyroidism. Instead, infants with hypothyroidism may exhibit poor weight gain, decreased activity, and dry, pale skin.

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: Testing the temperature of water before bathing is crucial to prevent burns, which is a significant risk for infants due to their sensitive skin. Infants have delicate skin that can easily be burned by water that is too hot. Testing the water temperature before bathing ensures that the water is at a safe and comfortable level for the infant. While choices A, B, and C are also important in accident prevention, such as reducing choking hazards, preventing electric shocks, and avoiding poisoning, testing the water temperature before bathing is the most immediate and direct action to prevent harm to the infant during bathing.

Correct Answer: B

Rationale: A cross-cut nipple is the most appropriate choice for feeding an infant with a unilateral cleft lip and palate. Using a cross-cut nipple helps regulate the flow of milk, making feeding easier for the infant and reducing the risk of aspiration. Plastic spoons, parenteral infusion, and rubber-tipped syringes are not recommended for feeding infants with cleft lip and palate as they can pose risks such as choking, aspiration, or inadequate milk intake. It is essential to choose a feeding method that minimizes these risks and ensures proper nutrition for the infant.

Correct Answer: B

Rationale: The priority nursing intervention for a child hospitalized for acute lymphoblastic leukemia (ALL) is preventing infection. Children with ALL have compromised immune systems, making them highly vulnerable to infections. Preventing infections through strict aseptic techniques, isolation precautions, and proper hygiene is crucial to safeguard the child's health. Administering antibiotics (choice A) may be necessary if an infection occurs, but the primary focus should be on infection prevention. While providing nutritional support (choice C) is important, preventing infection takes precedence due to its direct impact on the child's survival. Managing pain (choice D) is essential for the child's comfort but is not the priority over preventing life-threatening infections in this scenario.
