A client with hypertension is receiving teaching from a healthcare provider. Which statement demonstrates comprehension of the instruction?

Correct Answer: C

Rationale: Choice C is the correct answer because taking hypertension medication at the same time each day ensures its effectiveness in managing blood pressure. Consistency in medication intake is crucial to control hypertension. Option A focuses on dietary management, which is essential but not directly related to medication adherence. Option B is incorrect as stopping hypertension medication abruptly can lead to complications. Option D addresses the importance of exercise, which is beneficial for hypertension but not directly related to medication adherence.

Correct Answer: B

Rationale: The correct answer is B. Potassium levels above 5.0 mEq/L can lead to cardiac issues, and a level of 6.5 mEq/L requires immediate intervention. Hyperkalemia can cause life-threatening cardiac arrhythmias. Choices A, C, and D are within normal ranges and do not require immediate intervention in the context of hemodialysis monitoring.

Correct Answer: B

Rationale: The correct recommendation to prevent hypoglycemic episodes in a client with diabetes who reports frequent episodes is to monitor blood glucose levels frequently. By monitoring blood glucose levels, the nurse can make necessary adjustments to insulin dosage and diet to maintain blood sugar levels within the target range. Increasing protein intake (Choice A) is not directly related to preventing hypoglycemia; it is more important to focus on balancing carbohydrates and insulin. Increasing the dose of insulin (Choice C) without proper monitoring can lead to further hypoglycemic episodes. Similarly, reducing carbohydrate intake (Choice D) should be done cautiously as carbohydrates are a main source of energy and sudden reduction can cause hypoglycemia in diabetic patients.

Correct Answer: A

Rationale: The correct answer is A: "Blockage in a blood vessel supplying the brain." Ischemic stroke is caused by a blockage in a blood vessel supplying the brain, leading to reduced blood flow. Hemorrhagic stroke, on the other hand, is caused by bleeding in the brain due to a ruptured blood vessel. Choices B, C, and D are incorrect. Administering thrombolytics, avoiding anticoagulants, and preparing for surgery are specific management strategies that may apply to ischemic or hemorrhagic strokes but do not define the main differences between the two types of strokes.

Correct Answer: A

Rationale: When a patient is exhibiting signs of acute myocardial infarction (AMI), the priority action is to call for emergency assistance immediately. This ensures that the patient receives prompt and appropriate care, including interventions such as administering oxygen, nitroglycerin, and monitoring cardiac rhythm. Administering nitroglycerin should only be done if prescribed by a healthcare provider after assessment and confirmation of AMI. Monitoring the patient's cardiac rhythm is important but not the initial action needed in this critical situation. Administering oxygen and preparing for an ECG are important interventions but should follow the immediate step of calling for emergency assistance.
