Correct Answer: A

Rationale: The correct nursing priority for a patient experiencing an asthma exacerbation is to administer a bronchodilator. Bronchodilators help in relieving bronchoconstriction and improving breathing. While encouraging deep breathing, providing oxygen therapy, and monitoring oxygen saturation are essential aspects of managing asthma exacerbation, the priority is to administer a bronchodilator to address the acute bronchoconstriction.

Correct Answer: C

Rationale: The correct answer is C: Decreased bowel sounds. In hypokalemia, decreased bowel sounds are common due to slowed peristalsis. Hyperactive reflexes (choice A) and increased deep tendon reflexes (choice D) are more indicative of hyperkalemia. A strong, bounding pulse (choice B) is not typically associated with hypokalemia.

Correct Answer: C

Rationale: Identifying environmental hazards in the client's home is the priority during the initial visit with an older adult living alone. This action is crucial to prevent accidents, falls, and ensure the client's safety. While educating the client about their medical diagnosis, referring them to a meal delivery program, and arranging transportation for follow-up appointments are essential, addressing environmental hazards takes precedence as it directly impacts the client's immediate safety and well-being.

Correct Answer: B

Rationale: The correct answer is B because avoiding perfumed lotions is important to prevent skin irritation after radiation therapy. Using a heating pad (A) can further damage the skin, applying cold compresses (C) may not be recommended, and scrubbing the area daily with soap and water (D) can be too harsh on the skin, leading to further irritation and damage.

Correct Answer: D

Rationale: The correct instruction is to use the peak flow meter after using the rescue inhaler. This ensures accurate monitoring of asthma control during symptoms. Choice A is incorrect because peak flow measurements should be done before taking medications. Choice B is incorrect as the client should blow into the meter quickly and forcefully to get an accurate reading. Choice C is also incorrect as peak flow should be measured regularly, not just when feeling short of breath.
