Correct Answer: A

Rationale: The correct answer is A: Sterility. Mumps can lead to serious complications such as sterility, especially in adolescent males. Vaccination is essential to prevent this potential outcome. Hypopituitarism (Choice B) is not a typical complication of mumps. Choices C and D, decrease in libido and decrease in androgens, are not directly associated with mumps complications, particularly in the context of adolescents.

Correct Answer: D

Rationale: The correct answer is to test the temperature of water before bathing. This is crucial in preventing burns, which is a significant risk for infants due to their sensitive skin. Infants have delicate skin that can be easily burned by water that is too hot. Removing small objects from the floor (Choice A) is important to prevent choking hazards but not directly related to burns. Covering electric outlets with safety plugs (Choice B) is essential to prevent electrocution but does not address the risk of burns specifically. Removing toxic substances from low areas (Choice C) is necessary to prevent poisoning but is not directly related to burns. Therefore, the priority in this scenario is to prevent burns by ensuring the water temperature is safe for the infant.

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, increasing the risk of infections. Detecting and managing infections promptly is crucial to prevent complications and improve outcomes. Providing nutritional support is important, but infection prevention takes precedence due to the immediate threat it poses to the child's health. Monitoring for signs of bleeding is relevant in leukemia due to decreased platelet count, but infection surveillance is more critical. Monitoring for signs of pain is essential, but addressing infections promptly is the priority to prevent further deterioration in the child's condition.

Correct Answer: B

Rationale: Cellulitis is characterized by warmth at the site of skin disruption, indicating an infection. The correct answer is choice B. Choice A, 'Red, raised hair follicles,' is more indicative of folliculitis rather than cellulitis. Choice C, 'Papules progressing to vesicles,' is more characteristic of conditions like chickenpox, not cellulitis. Choice D, 'Honey-colored exudate,' is typical of wound infections with bacteria like Staphylococcus aureus, not cellulitis.

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.
