Correct Answer: A

Rationale: Corrected Rationale: Tremors can indicate lithium toxicity, which should be reported to the provider for further evaluation. Tremors are a significant sign of lithium toxicity and can lead to serious complications if not addressed promptly. Increased thirst, weight gain, and diarrhea are common side effects of lithium but are not typically indicative of toxicity. Therefore, the nurse should prioritize reporting tremors as it requires immediate attention.

Correct Answer: C

Rationale: The correct way to monitor a patient who has been prescribed digoxin is by checking digoxin levels. Digoxin is a medication used to treat various heart conditions, and monitoring its levels in the blood is crucial to prevent toxicity. Monitoring potassium levels (Choice A) is important as well, as digoxin can affect potassium levels, but checking digoxin levels is more specific to monitoring the medication itself. Monitoring heart rate (Choice B) is relevant but does not directly assess the medication levels. Checking blood glucose levels (Choice D) is not typically indicated specifically for patients prescribed digoxin.

Correct Answer: C

Rationale: The correct answer is C. Regular exercise is an essential component in managing hypertension. Exercising for at least 30 minutes a day, at least 5 days a week, can help control blood pressure. Checking blood pressure regularly (choice A) is important, but not as indicative of understanding the teaching as the commitment to regular exercise. Avoiding foods high in potassium (choice B) is not a typical recommendation for managing hypertension. Taking medication only when feeling dizzy (choice D) is incorrect and potentially dangerous; medications should be taken as prescribed by the healthcare provider.

Correct Answer: A

Rationale: The best intervention for a patient with suspected deep vein thrombosis (DVT) is to administer anticoagulants. Anticoagulants help prevent further clot formation and reduce the risk of complications such as pulmonary embolism. Applying compression stockings can help manage symptoms but does not address the underlying issue of clot formation. Encouraging ambulation is beneficial for overall circulation but may not be sufficient to treat DVT. Monitoring oxygen saturation is important, but it is not the primary intervention for suspected DVT.

Correct Answer: A

Rationale: Providing education on the importance of medication is crucial in managing hypertension in patients who are non-compliant. By educating the patient about the significance of taking medication as prescribed, the healthcare professional can help improve the patient's understanding and motivation to adhere to the treatment plan. Referring the patient to a specialist (Choice B) may be necessary in some cases but addressing non-compliance should start with education. Discontinuing the medication (Choice C) without addressing the root cause of non-compliance can worsen the patient's condition. Exploring alternative treatment options (Choice D) should come after ensuring the patient understands the importance of the current treatment regimen.
