Pharmacology for LPN

Correct Answer: C

Rationale: Before administering a calcium channel blocker to a client with hypertension, the healthcare provider should check the client's blood pressure. Calcium channel blockers are used to lower blood pressure, making it essential to assess the current blood pressure to ensure it is within the appropriate range for administration. Checking the apical pulse (choice A) is not the priority before administering a calcium channel blocker, as the focus should be on blood pressure. Serum calcium level (choice B) is not directly related to the administration of calcium channel blockers for hypertension. Respiratory rate (choice D) is not the primary parameter to check before administering a calcium channel blocker in this scenario.

Correct Answer: B

Rationale: Oatmeal with fresh fruit is a suitable choice for a client with coronary artery disease on a low-cholesterol diet as it is low in cholesterol and provides heart-healthy benefits. Eggs and bacon, cream of chicken soup, and grilled cheese sandwich are higher in cholesterol and may not be as heart-healthy for this client. Eggs and bacon are high in cholesterol, cream of chicken soup may contain saturated fats, and a grilled cheese sandwich typically contains high amounts of fat and cholesterol, making them less suitable choices for a client with coronary artery disease on a low-cholesterol diet.

Correct Answer: B

Rationale: Yellow or blurred vision can be a sign of digoxin toxicity. These visual disturbances are concerning as they indicate a potential adverse reaction to the medication. Recognizing this symptom promptly is crucial to prevent serious complications. Increased appetite, increased urination, and diarrhea are not typically associated with digoxin toxicity. Therefore, option B is the correct choice in this scenario.

Correct Answer: B

Rationale: The correct answer is B. Crossing the legs can further impede blood flow in clients with PAD, worsening symptoms. Avoiding leg crossing helps maintain adequate blood flow and reduces the risk of complications associated with peripheral artery disease. Choices A, C, and D are incorrect because elevating the legs, wearing tight compression stockings, and applying heat can exacerbate symptoms in PAD by restricting blood flow or causing potential harm.

Correct Answer: C

Rationale: The most critical instruction for a client after a myocardial infarction is to continue taking prescribed medications even if they feel well. This is essential in preventing another myocardial infarction or other complications. Discontinuing medications prematurely can be detrimental to the client's recovery and may increase the risk of further cardiovascular events. Choices A, B, and D are incorrect because engaging in sexual activity, physical activity, or returning to work are important aspects of the client's recovery, but not as crucial as ensuring medication compliance to prevent further cardiac issues.
