Correct Answer: A

Rationale: The correct answer is A: Crackles in the lung bases. In a client with pneumonia, crackles in the lung bases can indicate fluid accumulation, suggesting worsening respiratory status. This finding should be reported to the provider for further evaluation and management. Choice B, an oxygen saturation of 95%, is within the normal range and does not require immediate reporting. Choice C, a heart rate of 88/min, is also within normal limits and does not indicate an urgent need for intervention. Choice D, a frequent productive cough, is a common symptom in pneumonia and may not require immediate reporting unless it is severe or worsening. Therefore, crackles in the lung bases are the most concerning finding that warrants prompt attention.

Correct Answer: C

Rationale: The correct answer is C. Clients on warfarin therapy need to have their International Normalized Ratio (INR) checked regularly to monitor the medication's effectiveness and prevent complications like clotting or bleeding. Option A is incorrect because increasing leafy green vegetables can affect INR levels due to their vitamin K content. Option B is incorrect as grapefruit juice is not a significant concern with warfarin. Option D is important for medication adherence but does not specifically address the monitoring aspect required for warfarin therapy.

Correct Answer: C

Rationale: The correct intervention for a client with DVT is to apply cold packs to the affected extremity. Cold packs can help reduce swelling and pain by constricting blood vessels. Massaging the affected extremity can dislodge a clot and worsen the condition. Elevating the affected extremity helps with blood flow but is not the priority intervention for DVT. Performing range-of-motion exercises on the affected extremity can also dislodge a clot and is contraindicated.

Correct Answer: C

Rationale: The correct answer is C, Serum albumin level. Monitoring the serum albumin level helps assess the nutritional effectiveness of total parenteral nutrition (TPN). Serum albumin is a protein that reflects the long-term nutritional status of a patient. Serum calcium level (choice A) is not directly related to TPN effectiveness. Blood glucose level (choice B) is important to monitor in diabetic patients but is not the primary indicator of TPN efficacy. Serum sodium level (choice D) is more related to fluid balance and electrolyte status rather than the effectiveness of TPN.

Correct Answer: C

Rationale: The correct action the nurse should take for a client at risk for developing DVT is to apply sequential compression devices to the client's legs. This intervention helps prevent venous stasis by promoting circulation and reducing the risk of DVT. Encouraging the client to remain on bed rest (Choice A) can actually increase the risk of DVT due to immobility. Massaging the client's legs every 4 hours (Choice B) can dislodge blood clots and is contraindicated in DVT prevention. While administering anticoagulants as prescribed (Choice D) is a treatment for DVT, it is not a preventive measure for a client at risk.
