LPN Pharmacology Practice Test
1. A client has been taking levothyroxine for 6 months. Which of the following findings indicates that the medication is effective?
- A. Weight gain
- B. Increased heart rate
- C. Decreased TSH levels
- D. Elevated blood pressure
Correct answer: C
Rationale: In a client taking levothyroxine for thyroid hormone replacement, decreased TSH levels indicate that the medication is effective. TSH levels decrease as the thyroid hormone levels are adequately replaced by levothyroxine, signaling a positive response to treatment. Choices A, B, and D are incorrect because weight gain, increased heart rate, and elevated blood pressure are not expected findings indicating the effectiveness of levothyroxine therapy. Weight gain may suggest inadequate dosing, while increased heart rate and elevated blood pressure could indicate over-replacement or side effects of the medication.
2. When teaching a client about the use of lisinopril, which of the following instructions should the nurse include?
- A. Monitor your blood pressure regularly.
- B. Take the medication with food.
- C. Increase your intake of potassium-rich foods.
- D. Avoid grapefruit juice.
Correct answer: A
Rationale: The correct answer is to instruct the client to monitor their blood pressure regularly when taking lisinopril. Lisinopril is known to cause hypotension, so monitoring blood pressure is crucial to ensure it stays within a safe range. This monitoring helps in early detection of any potential issues related to low blood pressure, allowing for timely intervention. Choices B, C, and D are incorrect because taking lisinopril with food, increasing potassium-rich foods intake, and avoiding grapefruit juice are not specific instructions related to the safe and effective use of lisinopril.
3. 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.
4. A client with a diagnosis of myocardial infarction has a new activity prescription allowing the client to have bathroom privileges. As the client stands and begins to walk, the client begins to complain of chest pain. The nurse should take which action?
- A. Assist the client to get back into bed.
- B. Report the chest pain episode to the healthcare provider.
- C. Tell the client to stand still and take the client's blood pressure.
- D. Give a nitroglycerin (Nitrostat) tablet and assist the client to the bathroom.
Correct answer: A
Rationale: In a client with myocardial infarction experiencing chest pain during activity, the priority action is to stop the activity immediately to reduce the heart's workload and oxygen demand. Assisting the client back to bed helps in reducing stress on the heart and can prevent worsening of the condition. Reporting the chest pain episode to the healthcare provider is important but should not delay taking immediate action to alleviate symptoms. Taking the client's blood pressure and administering nitroglycerin are secondary actions after ensuring the client's safety and comfort. Therefore, the correct action is to assist the client back into bed.
5. A client has a new prescription for furosemide. Which of the following instructions should the nurse include?
- A. Take the medication with or without food.
- B. Monitor for signs of hypokalemia.
- C. Increase your intake of potassium-rich foods.
- D. Expect an increase in urination.
Correct answer: D
Rationale: The correct instruction to include when a client is prescribed furosemide is to expect an increase in urination. Furosemide is a diuretic that works by increasing urine production, so it is essential for the client to anticipate and understand this effect. Monitoring for signs of hypokalemia and increasing potassium-rich foods are not directly related to furosemide use. Hypokalemia is a potential side effect of furosemide, so monitoring for it is crucial. Increasing potassium-rich foods can help counteract potassium loss due to diuretic use. Taking furosemide with food is not required, as it can be taken with or without food.
