LPN Pharmacology Practice Questions
1. The client has atrial fibrillation and is receiving warfarin (Coumadin) therapy. Which laboratory test should be monitored to evaluate the effectiveness of the warfarin therapy?
- A. Prothrombin time (PT) and international normalized ratio (INR)
- B. Activated partial thromboplastin time (aPTT)
- C. Complete blood count (CBC)
- D. Fibrinogen levels
Correct answer: A
Rationale: Monitoring the Prothrombin time (PT) and international normalized ratio (INR) is crucial for assessing the effectiveness of warfarin therapy. These tests help determine the clotting ability of the blood and ensure that the client is within the desired therapeutic range to prevent clotting events or bleeding complications. Activated partial thromboplastin time (aPTT) (Choice B) is more commonly used to monitor heparin therapy, not warfarin. Complete blood count (CBC) (Choice C) and fibrinogen levels (Choice D) do not directly assess the effectiveness of warfarin therapy in the same way that PT and INR do.
2. A client with myocardial infarction suddenly becomes tachycardic, shows signs of air hunger, and begins coughing frothy, pink-tinged sputum. The nurse listens to breath sounds, expecting to hear which breath sounds bilaterally?
- A. Rhonchi
- B. Crackles
- C. Wheezes
- D. Diminished breath sounds
Correct answer: B
Rationale: In this scenario, the client is exhibiting signs of pulmonary edema, which can occur as a complication of myocardial infarction. Crackles are typically heard in cases of pulmonary edema, characterized by fluid accumulation in the lungs. These crackling sounds are heard during inspiration and sometimes expiration and are an indication of fluid-filled alveoli. Therefore, when assessing the client with these symptoms, the nurse would expect to hear crackles bilaterally. Rhonchi, which are coarse rattling respiratory sounds, are typically associated with conditions like bronchitis or pneumonia, not pulmonary edema. Wheezes are high-pitched musical sounds heard in conditions like asthma or COPD, not commonly present in pulmonary edema. Diminished breath sounds suggest decreased airflow or lung consolidation, not typical findings in pulmonary edema.
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 healthcare professional is assessing a client who has a new prescription for levothyroxine. Which of the following findings should the healthcare professional report to the provider?
- A. Weight gain
- B. Increased heart rate
- C. Heat intolerance
- D. Elevated blood pressure
Correct answer: C
Rationale: The correct answer is C: Heat intolerance. Heat intolerance is a concerning sign of levothyroxine toxicity and should be reported to the provider promptly. Levothyroxine is a medication used to treat hypothyroidism by supplementing the body's thyroid hormones. When a client experiences heat intolerance, it can indicate that the dose of levothyroxine is too high, leading to hyperthyroidism symptoms. Weight gain, increased heart rate, and elevated blood pressure are not typically associated with levothyroxine toxicity; instead, they are more commonly seen in conditions like hypothyroidism.
5. The healthcare provider is reinforcing dietary instructions to a client with coronary artery disease who has been prescribed a low-cholesterol diet. The healthcare provider should advise the client to choose which food item?
- A. Whole milk
- B. Oatmeal with fresh fruit
- C. Fried chicken
- D. Bacon and eggs
Correct answer: B
Rationale: Oatmeal with fresh fruit is the correct choice for a client with coronary artery disease on a low-cholesterol diet. Oatmeal is a heart-healthy option that is low in cholesterol and saturated fats. Fresh fruits are also a good source of essential nutrients and fiber. Choices A, C, and D are not suitable for a low-cholesterol diet. Whole milk, fried chicken, bacon, and eggs are high in cholesterol and saturated fats, which can be detrimental to individuals with coronary artery disease.
