Correct Answer: C

Rationale: Increased use of a rescue inhaler like albuterol may indicate worsening asthma symptoms. The nurse should first assess the client's respiratory status to determine the severity of the issue and the next steps in care. Option A is not the first action because assessing the client's condition should precede notifying the healthcare provider. Option B, scheduling a pulmonary function test, is not the priority as immediate assessment of the client's respiratory status is crucial. Instructing the client to decrease inhaler use should come after assessing the client's condition to ensure the appropriate intervention.

Correct Answer: C

Rationale: Irrigating and redressing a leg wound is a common task within the PN's scope of practice, making this assignment appropriate. Tasks like testing stool specimens for occult blood and assisting with ambulation of a client with a chest tube may require a higher level of training and assessment, typically performed by RNs. Admitting a client from the emergency room involves a comprehensive assessment and decision-making process, which is usually within the RN's responsibility.

Correct Answer: B

Rationale: An increase in urine output is a reliable indicator that the client's hydration status is improving. This reflects adequate fluid replacement and improved kidney function. Choice A is subjective and may not always indicate improved hydration. Choice C, while a positive sign, may be influenced by other factors such as medications or pain. Choice D, skin turgor returning to normal, is a delayed indicator of hydration status and may take time to improve even after hydration is initiated.

Correct Answer: A

Rationale: The correct answer is side-lying on the left with the head elevated 10 degrees. This position maximizes ventilation and promotes better perfusion to the unaffected lung. Placing the client in this position helps to optimize oxygenation and reduce pressure on the affected lung. Choices B, C, and D are incorrect because lying on the left side with the head elevated is essential to facilitate better lung expansion and gas exchange in the unaffected lung, while lying on the right side could further compromise the affected lung by increasing pressure on it.

Correct Answer: B

Rationale: The correct first action when a 6-year-old child steps on a rusty nail is to instruct the parent about tetanus boosters. This is important because stepping on a rusty nail increases the risk of tetanus infection. Choice A is incorrect as cleansing the foot comes after addressing the tetanus risk. Choice C is not the first action and should be done after addressing the immediate risk of tetanus. Choice D is not necessary as the priority is to prevent tetanus infection.
