LPN Pharmacology Practice Test Questions

Question 1 of 5

A client has been taking levothyroxine for 6 months. Which of the following findings indicates that the medication is effective?

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.

Question 2 of 5

During an assessment, a client taking valproic acid exhibits elevated liver enzymes. What finding should the nurse report to the provider?

Correct Answer: A

Rationale: Elevated liver enzymes are a critical finding that the nurse should report to the provider when assessing a client taking valproic acid. It can be indicative of hepatotoxicity, a severe side effect associated with valproic acid use. Timely reporting and intervention are essential to prevent further complications and ensure the client's safety and well-being. Choices B, C, and D are not directly related to valproic acid use or the manifestation of hepatotoxicity. Weight loss, dry mouth, and increased appetite are not typically associated with elevated liver enzymes in the context of valproic acid administration.

Question 3 of 5

When teaching a client about the adverse effects of simvastatin, which of the following findings should be included as an adverse effect?

Correct Answer: B

Rationale: Muscle pain should be included as an adverse effect when teaching a client about simvastatin. It can be a sign of rhabdomyolysis, a severe side effect associated with statins like simvastatin that involves muscle breakdown. Monitoring for muscle pain is crucial to prevent serious complications and ensure timely intervention. Tinnitus, diarrhea, and facial flushing are not typically associated with simvastatin use and are less common adverse effects compared to muscle pain.

Question 4 of 5

A client with heart failure is receiving digoxin. Which finding should indicate to the nurse that the client is experiencing digoxin toxicity?

Correct Answer: C

Rationale: Bradycardia is a hallmark sign of digoxin toxicity. Digoxin, a medication used to treat heart conditions, can lead to toxicity manifesting as bradycardia. Bradycardia occurs due to the drug's effect on slowing down the heart rate excessively. Constipation (Choice A) is not typically associated with digoxin toxicity. Blurred vision (Choice B) is more commonly linked to visual disturbances caused by digoxin, but it is not a defining sign of toxicity. Dry cough (Choice D) is not a recognized symptom of digoxin toxicity. It is crucial for the nurse to recognize the early signs of digoxin toxicity to prevent serious complications and provide appropriate interventions promptly.

Question 5 of 5

A client is receiving morphine for pain. Which of the following assessments is the priority?

Correct Answer: C

Rationale: The correct answer is C: Respiratory rate. Monitoring the respiratory rate is the priority assessment for a client receiving morphine due to the risk of respiratory depression. Morphine is a potent opioid that can cause respiratory depression, which is a serious adverse effect that can be life-threatening. Assessing the client's respiratory rate is crucial to detect any signs of respiratory depression early and intervene promptly. Assessing urine output is important but not as critical as monitoring for respiratory depression with morphine. Pupil reaction and bowel sounds are also important assessments but do not take precedence over monitoring the respiratory rate when a client is on morphine.
