Correct Answer: B

Rationale: The correct instruction when taking levothyroxine is to take it on an empty stomach. This enhances absorption and ensures the medication's effectiveness. Taking it with food or other substances, such as milk or antacids, can interfere with its absorption. Therefore, choices A, C, and D are incorrect.

Correct Answer: A

Rationale: The correct way for a healthcare provider to monitor a patient with suspected deep vein thrombosis (DVT) is to check for leg swelling. Leg swelling is a common symptom of DVT and monitoring for this sign is crucial for early detection and intervention. Encouraging ambulation may be beneficial for preventing DVT but is not the recommended method for monitoring an existing condition. Checking for redness may be useful in cases of superficial thrombophlebitis but is not specific to DVT. Monitoring oxygen saturation is more relevant for respiratory or cardiovascular conditions, not for DVT.

Correct Answer: C

Rationale: The correct action the nurse should take is to apply cold packs to the affected joints in the morning. Rheumatoid arthritis is characterized by inflammation, and applying cold packs can help reduce inflammation and stiffness in the joints. Encouraging the client to avoid physical activity in the morning (Choice A) may worsen stiffness, as movement is beneficial for joint mobility. While NSAIDs (Choice B) can help with pain and inflammation, applying cold packs directly to the affected joints is more targeted and effective. Performing passive range-of-motion exercises (Choice D) can be helpful, but applying cold packs is the priority for reducing inflammation and stiffness.

Correct Answer: B

Rationale: In a client with severe pain like the one described, the priority medication to administer is a potent analgesic like hydromorphone. Hydromorphone is a strong opioid pain medication that can effectively manage severe pain. Promethazine (Choice A) is an antiemetic and antihistamine, not a pain medication. Ketorolac (Choice C) is a nonsteroidal anti-inflammatory drug (NSAID) that is contraindicated in end-stage renal disease due to its potential to cause kidney damage. Amitriptyline (Choice D) is a tricyclic antidepressant used for conditions like depression and neuropathic pain, but it is not the first-line treatment for severe acute pain.

Correct Answer: D

Rationale: The correct answer is D. A platelet count of 100,000/mm3 is lower than the normal range, indicating thrombocytopenia, which is concerning in clients receiving chemotherapy. Thrombocytopenia can lead to an increased risk of bleeding and bruising. Choices A, B, and C fall within the normal range and would not be a cause for concern in a client receiving chemotherapy.
