HESI Pharmacology Quizlet
1. A client with hyperlipidemia is prescribed atorvastatin (Lipitor). Which instruction should the nurse include in the teaching plan?
- A. Take the medication in the morning.
- B. Avoid consuming grapefruit juice.
- C. Increase your intake of dairy products.
- D. Take the medication with food.
Correct answer: B
Rationale: The correct instruction for the nurse to include in the teaching plan is to advise the client to avoid consuming grapefruit juice. Grapefruit juice can increase the risk of atorvastatin (Lipitor) toxicity by inhibiting its metabolism. Atorvastatin is typically taken in the evening as cholesterol synthesis occurs at night. Increasing dairy intake is not specifically recommended for atorvastatin therapy, and the medication can be taken with or without food.
2. The nurse is caring for a client who is receiving heparin therapy. Which laboratory value should the nurse monitor to determine the effectiveness of the therapy?
- A. Prothrombin time (PT)
- B. Partial thromboplastin time (PTT)
- C. International normalized ratio (INR)
- D. Activated partial thromboplastin time (aPTT)
Correct answer: C
Rationale: The correct answer is C, International Normalized Ratio (INR). While INR is commonly used to monitor the effectiveness of warfarin therapy, in the case of heparin therapy, the Partial Thromboplastin Time (PTT) is the preferred test. Choice A, Prothrombin Time (PT), measures the activity of the extrinsic pathway of coagulation and is not the best choice for monitoring heparin therapy. Choice D, Activated Partial Thromboplastin Time (aPTT), is similar to PTT and is used to monitor heparin therapy, but PTT is the more specific test. Therefore, monitoring PTT is crucial in determining the effectiveness and safety of heparin therapy.
3. A male client with a history of deep vein thrombosis (DVT) is admitted with new onset shortness of breath and a productive cough. What is the nurse's priority action?
- A. Administer prescribed anticoagulant.
- B. Notify the healthcare provider.
- C. Auscultate lung sounds.
- D. Prepare for chest physiotherapy.
Correct answer: A
Rationale: Administering an anticoagulant is the nurse's priority action in this situation. Given the client's history of DVT and the presentation of new onset shortness of breath and a productive cough, there is a concern for a pulmonary embolism, which is a life-threatening complication of DVT. Administering an anticoagulant promptly is crucial to prevent further clot formation and to manage the existing clot, reducing the risk of pulmonary embolism. While auscultating lung sounds and preparing for chest physiotherapy are important actions in respiratory assessment and management, the priority in this case is to address the potential complication of a pulmonary embolism by administering the anticoagulant. Notifying the healthcare provider can be done after initiating the immediate intervention of anticoagulant therapy.
4. Which clients are at risk for kidney problems? (Select all that apply.)
- A. Clients taking synthetic creatine supplements
- B. Clients taking metformin for diabetes mellitus
- C. Clients taking high-dose nonsteroidal anti-inflammatory drugs (NSAIDs) for chronic back pain
- D. Clients taking prenatal vitamins and using albuterol nebulizers
Correct answer: A
Rationale: Clients who take synthetic creatine supplements, metformin, and high-dose or long-term NSAIDs are at risk for kidney dysfunction. Synthetic creatine supplements can cause kidney damage, metformin may rarely cause lactic acidosis leading to renal impairment, and high-dose NSAIDs can lead to acute kidney injury. Prenatal vitamins and albuterol nebulizers are not known to significantly impact kidney function, thus do not pose a risk for kidney problems.
5. A client with chronic obstructive pulmonary disease (COPD) is receiving oxygen therapy. Which finding indicates that the therapy is effective?
- A. The client is able to expectorate secretions easily.
- B. The client's oxygen saturation is 92%.
- C. The client's respiratory rate is 20 breaths per minute.
- D. The client's arterial blood gases show a pH of 7.35.
Correct answer: C
Rationale: In a client with COPD receiving oxygen therapy, an effective response is indicated by a respiratory rate of 20 breaths per minute. This suggests that the client is effectively oxygenating while maintaining an appropriate respiratory rate. Choices A, B, and D are incorrect because expectorating secretions easily, having an oxygen saturation of 92%, and arterial blood gases showing a pH of 7.35 are not specific indicators of the effectiveness of oxygen therapy in COPD. Oxygen saturation of 92% may still be suboptimal in COPD, and arterial blood gases showing a pH of 7.35 may not necessarily reflect the overall effectiveness of oxygen therapy.
