Correct Answer: A

Rationale: When assessing for infection in a patient post-surgery, checking the surgical site is crucial. Changes in the appearance of the surgical site, such as redness, swelling, warmth, or drainage, can indicate an infection. While checking for fever (Choice B) is also important as it can be a sign of infection, it is a more general symptom and may not always be present. Checking for abnormal breath sounds (Choice C) and skin color (Choice D) are not typically direct indicators of infection in a post-surgery patient.

Correct Answer: A

Rationale: The most important assessment for a patient with suspected pneumonia is to monitor lung sounds. Lung sounds provide crucial information about the severity of pneumonia, such as crackles or decreased air entry. This assessment helps in evaluating the effectiveness of ventilation and oxygenation. While checking oxygen saturation is important, monitoring lung sounds gives more direct information about the lung involvement in pneumonia. Assessing for cough and fever are also relevant but do not provide as direct and critical information as monitoring lung sounds in the context of suspected pneumonia.

Correct Answer: C

Rationale: Corrected Rationale: The nurse should monitor the client's INR to determine the effectiveness of warfarin therapy. INR monitoring is crucial as it reflects the blood's ability to clot properly. Warfarin is commonly used as an anticoagulant, and maintaining the INR within the therapeutic range ensures that the client is protected from both clotting and bleeding events. Monitoring serum calcium levels, platelet count, or WBC count is not directly related to assessing the effectiveness of warfarin therapy.

Correct Answer: A

Rationale: The most crucial nursing action for a patient post-surgery is to monitor vital signs. Monitoring vital signs helps in detecting early signs of complications such as hemorrhage, shock, or infection. While monitoring the surgical site is important for assessing wound healing and signs of infection, it is secondary to monitoring vital signs. Checking blood pressure and oxygen saturation are also important, but they are components of monitoring vital signs.

Correct Answer: C

Rationale: The correct answer is C because the client stating they should only take the inhaler when feeling short of breath indicates a need for further teaching. Clients with asthma should use their inhaler as prescribed, not just when short of breath. Choices A, B, and D demonstrate good asthma management practices. Choice A indicates understanding of using the albuterol inhaler before exercise to prevent exercise-induced symptoms. Choice B mentions the importance of not overusing the inhaler, which can indicate poor asthma control. Choice D shows awareness of rinsing the mouth after using a corticosteroid inhaler to prevent oral thrush.
