LPN Pharmacology Practice Questions Questions
Question 1 of 5
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?
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.
Question 2 of 5
A nurse is assessing a client who has been taking lithium carbonate. Which of the following findings should the nurse report to the provider?
Correct Answer: B
Rationale: The correct answer is B: Tremors. Tremors are a sign of lithium toxicity and should be reported immediately. Increased urination is a common side effect of lithium but not an urgent concern requiring immediate reporting. Weight gain is also a common side effect of lithium but does not indicate toxicity. Blurred vision is not typically associated with lithium toxicity; therefore, it is not the priority finding to report.
Question 3 of 5
The client has been prescribed atorvastatin (Lipitor) for hyperlipidemia. Which instruction should the nurse provide to the client?
Correct Answer: B
Rationale: The correct instruction for the nurse to provide to the client prescribed atorvastatin (Lipitor) for hyperlipidemia is to avoid drinking grapefruit juice while taking this medication. Grapefruit juice can interfere with the metabolism of atorvastatin, leading to an increased risk of side effects. It is crucial for the client to adhere to this instruction to ensure the effectiveness and safety of the treatment.
Choices A, C, and D are incorrect because taking the medication with breakfast, increasing dietary fiber intake, and avoiding foods high in potassium are not specific instructions related to atorvastatin therapy for hyperlipidemia.
Question 4 of 5
An 81-year-old male client has emphysema. He lives at home with his cat and manages self-care with no difficulty. When making a home visit, the nurse notices that this client's tongue is somewhat cracked, and his eyeballs appear sunken into his head. Which nursing intervention is indicated?
Correct Answer: A
Rationale: The client's cracked tongue and sunken eyes indicate dehydration.
Therefore, the priority nursing intervention is to help the client determine ways to increase his fluid intake. Dehydration can exacerbate the client's emphysema symptoms and lead to further complications. Monitoring and addressing the client's fluid intake is crucial for maintaining his health and well-being. Options B, C, and D are not the immediate priorities in this situation. While an eye examination, oxygen use, and sensitivity tests are relevant aspects of care, addressing dehydration through increased fluid intake takes precedence in this scenario.
Question 5 of 5
Nurse practitioner prescriptive authority is regulated by:
Correct Answer: C
Rationale: The correct answer is choice C, the State Board of Nursing for each state, because these boards establish the legal scope of practice for nurse practitioners, including prescriptive authority, which varies by state due to differing regulations.
Choice A, the National Council of State Boards of Nursing, is incorrect as it provides guidelines and licensure standards but doesn't directly regulate state-specific authority.
Choice B, the U.S. Drug Enforcement Administration, is wrong because it oversees controlled substances, not general prescribing rights.
Choice D, the State Board of Pharmacy, is also incorrect since it governs pharmacists, not NPs, and has no jurisdiction over their prescriptive authority.
