LPN Pharmacology Questions
1. A client is taking haloperidol. Which of the following findings should the nurse report to the provider?
- A. Weight gain
- B. Dry mouth
- C. Tremors
- D. Tardive dyskinesia
Correct answer: D
Rationale: The correct answer is D: Tardive dyskinesia. Tardive dyskinesia is a serious side effect associated with the long-term use of haloperidol. It is characterized by involuntary movements of the face, tongue, and extremities. Early detection is crucial as tardive dyskinesia may be irreversible and should be reported promptly to the healthcare provider for further evaluation and management. Choices A, B, and C are incorrect because weight gain, dry mouth, and tremors are common side effects of haloperidol but are not as concerning as tardive dyskinesia. While they should still be monitored and managed, tardive dyskinesia requires immediate attention due to its potentially irreversible nature.
2. The client with atrial fibrillation is receiving warfarin (Coumadin). Which laboratory test should be monitored to determine the effectiveness of the therapy?
- A. Prothrombin time (PT) and international normalized ratio (INR)
- B. Activated partial thromboplastin time (aPTT)
- C. Complete blood count (CBC)
- D. Fibrinogen level
Correct answer: A
Rationale: Monitoring Prothrombin time (PT) and international normalized ratio (INR) is crucial when a client is on warfarin therapy. These tests assess the clotting ability of the blood and help determine the appropriate dosage of warfarin to prevent complications such as bleeding or clotting events. PT and INR values within the therapeutic range indicate the effectiveness of warfarin in managing atrial fibrillation. Choice B, activated partial thromboplastin time (aPTT), is not typically used to monitor warfarin therapy; it is more commonly used to assess the effectiveness of heparin therapy. Choice C, complete blood count (CBC), does not directly assess the anticoagulant effect of warfarin. Choice D, fibrinogen level, is not a primary test for monitoring warfarin therapy; it is more relevant in assessing conditions like disseminated intravascular coagulation.
3. The LPN/LVN is assisting in the care of a client who has been prescribed enoxaparin (Lovenox) for the prevention of deep vein thrombosis (DVT). Which instruction should the nurse reinforce with the client?
- A. Avoid consuming foods high in vitamin K while taking this medication.
- B. Administer the injection in the same site each time for consistency.
- C. Report any unusual bleeding or bruising to your healthcare provider.
- D. Do not take aspirin if you experience any mild pain or discomfort.
Correct answer: C
Rationale: The correct instruction for the nurse to reinforce with the client is to report any unusual bleeding or bruising to their healthcare provider. This is crucial because unusual bleeding or bruising may indicate excessive anticoagulation, a potential side effect of enoxaparin. Prompt reporting to a healthcare provider is necessary to prevent complications. Choices A, B, and D are incorrect. Choice A is not directly related to enoxaparin and vitamin K interactions. Choice B is incorrect as rotating injection sites is essential for preventing tissue damage and irritation. Choice D is also incorrect as aspirin can increase the risk of bleeding when taken with enoxaparin.
4. The LPN/LVN is reinforcing instructions to a client on the use of a metered-dose inhaler. The nurse should recognize that the client is using the inhaler correctly if the client takes which action?
- A. Takes a deep breath and then exhales just before administration
- B. Holds the mouthpiece 1 to 2 inches from the mouth
- C. Inhales the medication and then exhales immediately after administration
- D. Performs 3 short inhalations and then exhales deeply after administration
Correct answer: A
Rationale: When using a metered-dose inhaler, the client should take a deep breath and then exhale just before administration. This technique helps ensure that the medication is inhaled effectively. By exhaling before administration, the client can fully inhale the medication into the lungs, maximizing its therapeutic effects. Choice B is incorrect because holding the mouthpiece 1 to 2 inches from the mouth is not a crucial step for using a metered-dose inhaler correctly. Choice C is incorrect because inhaling the medication and then exhaling immediately after administration would not allow the medication to be adequately absorbed into the lungs. Choice D is incorrect because performing 3 short inhalations and then exhaling deeply after administration is not the correct technique for using a metered-dose inhaler.
5. A client is admitted to the emergency department with a suspected myocardial infarction (MI). The nurse should prepare the client for which immediate diagnostic test?
- A. Chest x-ray
- B. Electrocardiogram (ECG)
- C. Echocardiogram
- D. Coronary angiography
Correct answer: B
Rationale: An Electrocardiogram (ECG) is the most immediate and essential test to diagnose a myocardial infarction (MI) and assess the extent of heart damage. An ECG can quickly identify changes in the heart's electrical activity, allowing prompt initiation of appropriate interventions. A chest x-ray (Choice A) may show other conditions affecting the heart, but it is not the immediate test of choice for diagnosing an MI. An echocardiogram (Choice C) and coronary angiography (Choice D) are valuable in further assessing cardiac function and anatomy post-MI but are not the first-line diagnostic tests due to their time-consuming nature compared to an ECG.
