LPN Pharmacology Practice Questions

Correct Answer: A

Rationale: Limiting alcohol intake is an essential lifestyle modification recommended for managing hypertension. Excessive alcohol consumption can raise blood pressure, so limiting it to one drink per day is beneficial in controlling hypertension. Alcohol moderation is a key part of a heart-healthy lifestyle for individuals with high blood pressure. Choice B is incorrect because increasing sodium intake can actually worsen hypertension by retaining water and increasing blood pressure. Choice C is incorrect because while exercise is important for overall health, moderate-intensity exercise is recommended for individuals with hypertension to avoid excessive strain on the heart. Choice D is incorrect because high potassium foods like bananas are actually beneficial for individuals with hypertension as they can help lower blood pressure.

Correct Answer: C

Rationale: The correct first action for the nurse to take is to check the client's status and lead placement. This step is crucial to ensure that the alarm is not triggered by a simple issue such as lead displacement. Calling a code blue (choice A) is premature without assessing the client first. Contacting the healthcare provider (choice B) can be done after ruling out basic causes for the alarm. Pressing the recorder button (choice D) is not as urgent as checking the client's status and lead placement in this scenario.

Correct Answer: B

Rationale: In a client with coronary artery disease (CAD) experiencing dyspnea at rest, the priority intervention should be to elevate the head of the bed to at least 45 degrees. This position helps reduce the work of breathing, optimizes lung expansion, and can alleviate symptoms of dyspnea by improving oxygenation and ventilation. Providing a walker for ambulation, monitoring oxygen saturation, and having an oxygen cannula at the bedside are important interventions but not the priority when the client is experiencing dyspnea at rest. Elevating the head of the bed is crucial to improve respiratory function and should be prioritized in this situation.

Correct Answer: B

Rationale: Spinach is high in vitamin K, which can interfere with the effectiveness of warfarin. It is important for clients taking warfarin to maintain consistent levels of vitamin K intake to ensure the medication works properly. Foods rich in vitamin K, such as spinach, can counteract the effects of warfarin, leading to potential complications. Therefore, clients on warfarin are advised to either avoid or consume vitamin K-rich foods, like spinach, in consistent amounts to maintain the medication's efficacy. Bananas, oranges, and yogurt are not high in vitamin K and do not significantly impact the effectiveness of warfarin, making them safe options for clients taking this medication.

Correct Answer: A

Rationale: In this case, the nurse should check the client's smoking history next. Smoking is a significant risk factor for peripheral vascular disease, leading to the development of thrombophlebitis and claudication. It is important to assess this risk factor as it can significantly impact the client's vascular health and the progression of their current symptoms. Choices B, C, and D are incorrect because they are not directly related to the symptoms described by the client. Recent exposure to allergens or insect bites would typically present with different symptoms, and familial tendency toward peripheral vascular disease is not the immediate concern in this case.
