1. A client with a urinary tract infection is prescribed trimethoprim. What is the most important teaching point?
- A. Take the medication only when symptoms are severe.
- B. Take the medication until symptoms disappear.
- C. Report any pain or burning with urination.
- D. Take the full course of antibiotics, even if symptoms improve.
Correct answer: D
Rationale: The correct answer is D: 'Take the full course of antibiotics, even if symptoms improve.' It is crucial for clients to complete the full course of antibiotics as prescribed to ensure that the infection is fully eradicated and to prevent the development of antibiotic resistance. Choice A is incorrect because antibiotics should not be reserved for severe symptoms only; they should be taken as prescribed. Choice B is incorrect as stopping the medication once symptoms disappear may lead to a relapse of the infection. Choice C is important but not the most crucial teaching point when compared to completing the full course of antibiotics.
2. Which of the following assessments is the most important for a patient receiving IV potassium?
- A. Respiratory rate
- B. Heart rate
- C. Blood pressure
- D. Oxygen saturation
Correct answer: C
Rationale: The most important assessment for a patient receiving IV potassium is monitoring blood pressure. IV potassium can cause significant changes in cardiac function, leading to adverse effects such as arrhythmias and cardiac arrest. While respiratory rate, heart rate, and oxygen saturation are important parameters to monitor in clinical practice, blood pressure takes precedence in patients receiving IV potassium due to its direct impact on cardiovascular function. Changes in blood pressure can be an early indicator of potassium-induced cardiac complications, making it crucial to monitor closely during administration.
3. The nurse enters a client's room to administer scheduled daily medications and observes the client leaning forward and using pursed lip breathing. Which action is most important for the nurse to implement first?
- A. Evaluate the oxygen saturation.
- B. Administer a bronchodilator.
- C. Assist the client to sit upright.
- D. Encourage slow, deep breathing.
Correct answer: A
Rationale: In this scenario, the nurse should first evaluate the oxygen saturation. This action is crucial as it provides immediate information on the client's respiratory status. Assessing the oxygen saturation can help determine the adequacy of oxygenation and guide further interventions. Administering a bronchodilator (Choice B) may be necessary based on assessment findings, but it should not be the first action without knowing the oxygen saturation level. While assisting the client to sit upright (Choice C) is generally beneficial for respiratory function, in this case, assessing oxygen saturation takes precedence. Encouraging slow, deep breathing (Choice D) can be helpful, but it is secondary to evaluating the oxygen saturation in this situation.
4. A client with a history of myocardial infarction (MI) is admitted with chest pain. Which laboratory test should the nurse expect to be ordered to determine if the client is experiencing another MI?
- A. Troponin
- B. Myoglobin
- C. CK-MB
- D. C-reactive protein
Correct answer: A
Rationale: Troponin is the most specific and sensitive laboratory test for detecting myocardial infarction (MI). It is released when there is damage to the heart muscle, making it a valuable marker for diagnosing another MI. Myoglobin and CK-MB can also be elevated in MI, but troponin is preferred due to its higher specificity. C-reactive protein is a marker of inflammation and not specific to MI.
5. A client with Alzheimer's disease is prescribed donepezil. What is the most important teaching point?
- A. Take the medication as directed for best results.
- B. Report any unusual changes in behavior.
- C. This medication helps improve cognitive function.
- D. This medication is not a cure for Alzheimer's disease.
Correct answer: C
Rationale: The most important teaching point for a client prescribed donepezil is that it helps improve cognitive function. While it is important to take the medication as directed for best results (choice A) and report any unusual changes in behavior (choice B), the key point is that donepezil is not a cure for Alzheimer's disease (choice D). Therefore, the correct answer is C.
