LPN Pharmacology Practice Test
1. A healthcare professional is reviewing laboratory results for a client with rheumatoid arthritis prescribed methotrexate. Which of the following laboratory results should the healthcare professional report to the provider?
- A. WBC count 1,200/mm³
- B. Hemoglobin 14 g/dL
- C. Platelets 150,000/mm³
- D. Blood glucose 110 mg/dL
Correct answer: A
Rationale: A WBC count of 1,200/mm³ indicates leukopenia, a serious side effect of methotrexate that can lead to increased risk of infections. It is crucial to report this finding promptly to the provider for further evaluation and possible adjustments in the treatment plan. Choices B, C, and D are within normal ranges and do not represent significant concerns related to methotrexate therapy in this context.
2. A client's serum calcium level is 7.9 mg/dL. The nurse is immediately concerned, knowing that this level could lead to which complication?
- A. Stroke
- B. Cardiac arrest
- C. High blood pressure
- D. Urinary stone formation
Correct answer: B
Rationale: A serum calcium level below normal (hypocalcemia) can lead to cardiac arrhythmias and potentially cardiac arrest. Calcium plays a crucial role in cardiac muscle contractility, and low levels can disrupt normal heart function, potentially leading to fatal arrhythmias and cardiac arrest. Choices A, C, and D are incorrect as hypocalcemia is not directly associated with stroke, high blood pressure, or urinary stone formation. The immediate concern with low serum calcium levels is the risk of cardiac complications.
3. A client with a history of heart failure is admitted with a diagnosis of pulmonary edema. Which intervention should the LPN/LVN expect to assist with first?
- A. Administer a diuretic as prescribed.
- B. Place the client in a high Fowler's position.
- C. Prepare the client for intubation.
- D. Insert an indwelling urinary catheter.
Correct answer: B
Rationale: In a client with pulmonary edema, placing them in a high Fowler's position is the priority intervention. This position helps to improve ventilation and oxygenation by decreasing venous return, reducing the workload on the heart, and facilitating fluid redistribution from the lungs. It is crucial to optimize respiratory function and oxygenation before considering other interventions like administering medications, preparing for intubation, or inserting a urinary catheter. Administering a diuretic, preparing for intubation, or inserting a urinary catheter may be necessary but should follow the priority of improving oxygenation through positioning.
4. A client with a diagnosis of hypertension is prescribed atenolol (Tenormin). The nurse should monitor the client for which common side effect of this medication?
- A. Tachycardia
- B. Dry mouth
- C. Hypotension
- D. Increased appetite
Correct answer: C
Rationale: Corrected Rationale: Atenolol is a beta-blocker that commonly causes hypotension by lowering blood pressure. Therefore, monitoring for hypotension is crucial to prevent potential complications in the client receiving this medication. The other options are incorrect: A) Tachycardia is not a common side effect of atenolol as it typically reduces heart rate, B) Dry mouth is not a typical side effect of atenolol, and D) Increased appetite is not commonly associated with atenolol use.
5. A client has a new prescription for sertraline. Which of the following instructions should the nurse include?
- A. Take the medication in the morning.
- B. Avoid consuming grapefruit juice.
- C. Take the medication with a full glass of water.
- D. Monitor for signs of weight gain.
Correct answer: B
Rationale: The correct instruction for the nurse to include is to 'Avoid consuming grapefruit juice.' Grapefruit juice can increase sertraline levels, leading to an elevated risk of side effects. Instructing the client to avoid grapefruit juice is crucial to prevent potential interactions that could impact the effectiveness and safety of the medication. The other options are not directly related to sertraline administration. Taking the medication in the morning may vary depending on individual preferences or the prescriber's directions. Taking the medication with a full glass of water is a general instruction for many medications and not specific to sertraline. Monitoring for signs of weight gain is important but not a direct instruction related to taking sertraline.
