What is the most important nursing assessment for a patient with suspected deep vein thrombosis (DVT)?

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: A

Rationale: The correct answer is A: Administer analgesics regularly. Postoperative pain management often requires a scheduled, around-the-clock administration of analgesics to maintain a consistent level of pain relief and minimize the risk of breakthrough pain. Choice B, administering pain medication PRN (as needed), may lead to inadequate pain control as the medication is not given preemptively. Choice C, encouraging deep breathing exercises, can be beneficial for pain management but should be used as an adjunct to analgesic therapy. Choice D, providing distraction techniques, may help some patients cope with pain but should not be the primary method of pain management postoperatively.

Correct Answer: C

Rationale: The correct answer is to monitor aPTT for a patient receiving heparin therapy. The activated partial thromboplastin time (aPTT) is used to assess and adjust heparin dosage to ensure the patient is within the therapeutic range for anticoagulation. Monitoring the aPTT helps in preventing both clotting and bleeding complications. Platelet count (Choice A) is important to monitor for patients receiving antiplatelet therapy, not heparin. PT/INR (Choice B) is typically monitored for patients on warfarin therapy, not heparin. Monitoring the complete blood count (CBC) (Choice D) is essential for various conditions but is not specific to monitoring heparin therapy.

Correct Answer: A

Rationale: The correct answer is A, Bradycardia. Bradycardia, or a slower than normal heart rate, is a classic sign of digoxin toxicity. Digoxin is a medication commonly used to treat heart conditions, but an excess of digoxin in the body can lead to toxicity. This toxicity can manifest as various symptoms, with bradycardia being one of the most common ones. Hypertension (high blood pressure) and tachycardia (fast heart rate) are not typical signs of digoxin toxicity. Tachypnea, which refers to rapid breathing, is also not a common sign of digoxin toxicity.

Correct Answer: B

Rationale: When administering opioids, monitoring the respiratory rate is crucial to detect any signs of respiratory depression, which is a serious side effect of opioid use. Monitoring blood pressure, heart rate, and oxygen saturation are important parameters to assess a patient's overall condition, but they are not the primary focus when administering opioids.
