LPN Pharmacology Practice Questions
1. The client is receiving heparin therapy for deep vein thrombosis (DVT). Which lab test should be monitored to evaluate the effectiveness of heparin?
- A. Prothrombin time (PT)
- B. International normalized ratio (INR)
- C. Activated partial thromboplastin time (aPTT)
- D. Fibrinogen levels
Correct answer: C
Rationale: Activated partial thromboplastin time (aPTT) is the appropriate lab test to monitor the therapeutic effectiveness of heparin therapy. Heparin affects the intrinsic pathway of the coagulation cascade, and monitoring aPTT helps ensure the client is within the therapeutic range to prevent clot formation. Prothrombin time (PT) and International normalized ratio (INR) are used to monitor warfarin therapy, a different anticoagulant that affects the extrinsic pathway of the coagulation cascade. Fibrinogen levels are not specific to monitoring heparin therapy.
2. A client has a new prescription for alendronate. Which of the following instructions should be included in the teaching?
- A. Take the medication with a full glass of water.
- B. Lie down for 30 minutes after taking the medication.
- C. Take the medication at bedtime.
- D. Avoid dairy products while taking the medication.
Correct answer: A
Rationale: The correct instruction for taking alendronate is to take it with a full glass of water to prevent esophageal irritation. This helps ensure proper absorption and reduces the risk of irritation to the esophagus. Choice B is incorrect because patients should remain upright for at least 30 minutes after taking alendronate to prevent esophageal irritation. Choice C is incorrect as alendronate should be taken in the morning on an empty stomach. Choice D is also incorrect as there is no specific requirement to avoid dairy products while taking alendronate.
3. A client with heart failure is prescribed an angiotensin-converting enzyme (ACE) inhibitor. What instruction should the nurse reinforce to the client?
- A. Take the medication at bedtime.
- B. Report a persistent dry cough.
- C. Increase potassium-rich foods in the diet.
- D. Avoid taking the medication with meals.
Correct answer: B
Rationale: The correct answer is B. A persistent dry cough is a common side effect of ACE inhibitors and should be reported to the healthcare provider. This symptom can indicate a potential issue with the medication that may require adjustment or discontinuation. Choices A, C, and D are incorrect. Taking the medication at bedtime or with meals is not a specific instruction for ACE inhibitors. Increasing potassium-rich foods in the diet is not directly related to ACE inhibitor therapy and may not be suitable for all patients.
4. The client is receiving intravenous heparin for the treatment of a pulmonary embolism. Which medication should the nurse ensure is readily available?
- A. Protamine sulfate
- B. Vitamin K
- C. Calcium gluconate
- D. Magnesium sulfate
Correct answer: A
Rationale: Protamine sulfate is the antidote for heparin, used to reverse its anticoagulant effects. It should be readily available in case of bleeding complications, as it can rapidly neutralize the effects of heparin and prevent excessive bleeding. Vitamin K is used to reverse the effects of warfarin, not heparin (Choice B). Calcium gluconate is used to treat calcium deficiencies, not indicated for heparin therapy (Choice C). Magnesium sulfate is used for conditions like preeclampsia and eclampsia, not for reversing heparin effects (Choice D).
5. A client who had a myocardial infarction (MI) two days ago reports chest pain radiating to the left arm. What should the nurse do immediately?
- A. Administer morphine
- B. Obtain an electrocardiogram (ECG)
- C. Apply oxygen via nasal cannula
- D. Administer sublingual nitroglycerin
Correct answer: B
Rationale: Obtaining an ECG is crucial in this situation because it helps in assessing for potential complications, such as a recurrent MI or ongoing ischemia. This diagnostic test provides valuable information to guide further interventions and treatment. Administering morphine, oxygen, or nitroglycerin may be necessary but obtaining an ECG takes precedence to evaluate the cardiac status and determine the appropriate course of action. Administering morphine without assessing the current cardiac status through an ECG can mask important diagnostic clues. Applying oxygen and administering nitroglycerin are supportive measures that can follow the ECG to address potential hypoxia and ischemic pain relief, respectively.
