LPN Pharmacology Questions
1. A nurse is assessing a client who is taking hydrocodone. Which of the following findings should the nurse report to the provider?
- A. Constipation
- B. Sedation
- C. Dry mouth
- D. Respiratory depression
Correct answer: D
Rationale: The correct answer is D: Respiratory depression. Hydrocodone is an opioid medication that can cause respiratory depression, a serious side effect that should be reported immediately to the healthcare provider. Constipation, sedation, and dry mouth are common side effects of hydrocodone but are not as concerning as respiratory depression. Constipation can be managed with lifestyle modifications and medications, sedation may improve with time or dosage adjustments, and dry mouth is a common and usually benign side effect.
2. A client has a new prescription for levothyroxine. Which of the following instructions should the nurse include?
- A. Take the medication on an empty stomach.
- B. Take the medication with food.
- C. Take the medication at bedtime.
- D. Take the medication with an antacid.
Correct answer: A
Rationale: The correct answer is A: 'Take the medication on an empty stomach.' Levothyroxine should be taken on an empty stomach to ensure optimal absorption. Food, especially high-fiber foods, can interfere with the absorption of levothyroxine. Taking it with an antacid or at bedtime may also affect its absorption. Instructing the client to take the medication on an empty stomach will help maintain consistent blood levels of levothyroxine. Choice B is incorrect as taking levothyroxine with food can reduce its absorption. Choice C is incorrect because taking levothyroxine at bedtime may lead to inconsistent blood levels due to food intake during the day. Choice D is incorrect as antacids can interfere with the absorption of levothyroxine.
3. What predisposing factor most likely contributed to the proximal end of the femur fracture in a 62-year-old woman who lives alone and tripped on a rug in her home?
- A. Failing eyesight leading to an unsafe environment
- B. Renal osteodystrophy from chronic kidney disease (CKD)
- C. Osteoporosis from declining hormone levels
- D. Cerebral vessel changes causing transient ischemic attacks
Correct answer: C
Rationale: The most likely predisposing factor contributing to the proximal end of the femur fracture in a 62-year-old woman is osteoporosis resulting from declining hormone levels. Osteoporosis weakens the bones, making them more susceptible to fractures, especially in older adults, particularly women. In this case, the fracture can be attributed to the bone density loss associated with osteoporosis, which is a common concern in postmenopausal women. Choices A, B, and D are less likely to have directly contributed to the femur fracture in this scenario. Failing eyesight may increase the risk of falls but does not directly weaken the bones. Renal osteodystrophy affects bone health but is less common in this age group. Cerebral vessel changes causing transient ischemic attacks are related to vascular issues, not bone strength.
4. A nurse is assessing a client who has a new prescription for enalapril. Which of the following findings is a priority for the nurse to report to the provider?
- A. Frequent urination
- B. Dry cough
- C. Tremors
- D. Dizziness
Correct answer: D
Rationale: The correct answer is D: Dizziness. Dizziness is a sign of hypotension, a potential adverse effect of enalapril. Enalapril is an ACE inhibitor commonly prescribed for hypertension. Hypotension is a serious side effect that can lead to complications such as falls and injuries. Reporting dizziness promptly is crucial to prevent any harm to the client. Choices A, B, and C are not directly associated with enalapril use and are less concerning compared to the potential implications of hypotension indicated by dizziness.
5. When preparing to administer medication to a client, what action should the nurse take first?
- A. Verify the client's identity.
- B. Check the medication expiration date.
- C. Review the client's medical history.
- D. Obtain the client's vital signs.
Correct answer: A
Rationale: Verifying the client's identity is the initial and most critical step in medication administration. It is crucial to confirm that the right medication is being given to the correct patient. Checking the client's identity helps prevent medication errors and ensures patient safety. Checking the medication expiration date (choice B) is important but should come after verifying the client's identity. Reviewing the client's medical history (choice C) is valuable but not the first step in medication administration. Obtaining the client's vital signs (choice D) is essential in some situations but is usually not the first action needed before administering medication.
