Correct Answer: A

Rationale: The most important nursing assessment for a patient with suspected deep vein thrombosis (DVT) is to check for leg pain. Leg pain is a cardinal symptom of DVT and is often the initial indicator of a blood clot. While assessing for warmth, swelling, and redness are also important in DVT evaluation, leg pain is the most crucial as it can prompt further diagnostic testing and interventions. Performing Homan's sign test is no longer recommended due to its low specificity and potential to dislodge a clot, causing complications. Monitoring for redness is important but may not always be present in DVT cases. Assessing for warmth and swelling is relevant but still secondary to the assessment of leg pain in suspected DVT cases.

Correct Answer: B

Rationale: The correct answer is B: Apply a hydrocolloid dressing. Applying a hydrocolloid dressing helps create a moist environment that promotes healing in clients with stage 2 pressure injuries. Choice A, cleansing the wound with povidone-iodine, is not recommended for stage 2 pressure injuries as it can be too harsh on the skin. Performing debridement as needed, as mentioned in choice C, is not typically indicated for stage 2 pressure injuries, which involve partial-thickness skin loss. Keeping the wound open to air, as stated in choice D, is also not the preferred approach for managing stage 2 pressure injuries, as maintaining a moist environment is key to promoting healing.

Correct Answer: C

Rationale: Dependent edema is a common finding in clients with pneumonia due to fluid retention and decreased mobility. Bradycardia (Choice A) is not typically associated with pneumonia. Crackles in the lung bases (Choice B) are more commonly heard in conditions like heart failure or pulmonary edema. A productive cough (Choice D) can be seen in pneumonia but is not as specific as dependent edema.

Correct Answer: B

Rationale: The correct answer is B. Eating more leafy green vegetables can increase vitamin K intake, which may reduce the effectiveness of warfarin. This can lead to fluctuations in the International Normalized Ratio (INR) levels, affecting the medication's efficacy. Choices A, C, and D are correct statements. Taking warfarin every other day, using a soft toothbrush to prevent gum bleeding, and having regular INR checks are all appropriate and important actions when taking warfarin.

Correct Answer: A

Rationale: Administering oxygen is the primary nursing action for a patient with confusion post-surgery because it helps address any potential hypoxia that may be contributing to the patient's confusion. While repositioning the patient, monitoring vital signs, and checking oxygen saturation are important nursing interventions, administering oxygen takes precedence in ensuring adequate oxygenation levels, which is crucial in managing post-surgery confusion.
