LPN Pharmacology Practice Test
1. A client has a new prescription for prednisone. Which of the following statements should the nurse include in the teaching?
- A. You may experience weight gain.
- B. Increase your intake of vitamin K.
- C. Expect increased urinary output.
- D. You may have dark, tarry stools.
Correct answer: A
Rationale: The correct answer is A: 'You may experience weight gain.' Prednisone commonly causes weight gain as a side effect, so it is important for the client to be aware of this potential outcome. Monitoring weight changes can be essential in managing the medication's effects and overall health. Choices B, C, and D are incorrect. Increasing vitamin K intake is not specifically related to prednisone use. Expecting increased urinary output is not a common side effect of prednisone. Dark, tarry stools are more commonly associated with gastrointestinal bleeding rather than prednisone use.
2. The healthcare provider is reinforcing teaching for a client who is starting statin therapy. Which dietary advice should the healthcare provider give?
- A. Eat more whole grains.
- B. Avoid foods high in potassium.
- C. Avoid grapefruit and grapefruit juice.
- D. Increase intake of dairy products.
Correct answer: C
Rationale: The correct answer is C: Avoid grapefruit and grapefruit juice. Grapefruit and grapefruit juice can interfere with the metabolism of statins, leading to an increased risk of adverse effects. It is crucial for clients on statin therapy to avoid grapefruit products to ensure the medication's effectiveness and safety. Choices A, B, and D are incorrect because they do not directly impact the metabolism or effectiveness of statin therapy.
3. When teaching a client about the adverse effects of simvastatin, which of the following findings should be included as an adverse effect?
- A. Tinnitus
- B. Muscle pain
- C. Diarrhea
- D. Facial flushing
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.
4. 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.
5. A healthcare professional is preparing to administer a unit of packed red blood cells to a client. Which of the following actions should the healthcare professional take?
- A. Prime the blood tubing with normal saline.
- B. Verify the client’s identity using two identifiers.
- C. Infuse the blood rapidly over 30 minutes.
- D. Obtain the client’s vital signs every 4 hours during the transfusion.
Correct answer: B
Rationale: Verifying the client’s identity using two identifiers is a critical patient safety measure to ensure the correct patient receives the blood transfusion. This process involves checking the patient's identity using at least two unique identifiers, such as name, date of birth, or medical record number, to prevent administration errors. Priming the blood tubing with normal saline is necessary to ensure there are no air bubbles in the tubing, but it is not the immediate action required before administering the blood. Infusing packed red blood cells over 30 minutes is generally too rapid and can lead to adverse reactions; a slower rate is recommended for safe administration. Obtaining vital signs every 4 hours during the transfusion is not frequent enough to monitor the client adequately for potential transfusion reactions or complications; vital signs should be monitored more frequently, especially during the initial phase of the transfusion.
