1. The nurse is caring for a patient who is taking trimethoprim-sulfamethoxazole (TMP-SMX). The nurse learns that the patient takes an angiotensin-converting enzyme (ACE) inhibitor. To monitor for drug interactions, the nurse will request an order for which laboratory test(s)?
- A. A complete blood count
- B. BUN and creatinine
- C. Electrolytes
- D. Glucose
Correct answer: C
Rationale: The correct answer is 'C. Electrolytes.' When trimethoprim-sulfamethoxazole (TMP-SMX) is taken with an ACE inhibitor, there is an increased risk of hyperkalemia due to the combined effects on potassium levels. Monitoring electrolytes, specifically potassium, is essential to detect and manage this potential drug interaction. Choices A, B, and D are incorrect because while they are important tests in general patient care, they are not specifically indicated to monitor for the drug interaction between TMP-SMX and ACE inhibitors.
2. A client who has just undergone a skin biopsy is listening to discharge instructions from the nurse. The nurse determines that the client has misunderstood the directions if the client indicates that as part of aftercare he plans to:
- A. Use the antibiotic ointment as prescribed
- B. Return in 7 days to have the sutures removed
- C. Apply cool compresses to the site twice a day for 20 minutes
- D. Call the physician if excessive drainage from the wound occurs
Correct answer: C
Rationale: The correct answer is C. Applying cool compresses to the site twice a day for 20 minutes is not a recommended aftercare practice for a skin biopsy. After a skin biopsy, it is important to keep the dressing dry and in place for a minimum of 8 hours. Choice A is correct as using the antibiotic ointment as prescribed is a common post-biopsy instruction to prevent infection. Choice B is also correct as returning in 7 days to have the sutures removed is part of the typical follow-up care after a skin biopsy. Choice D is correct as it is important to call the physician if excessive drainage from the wound occurs to prevent complications.
3. A client has driven himself to the emergency department. He is 50 years old, has a history of hypertension, and informs the nurse that his father died from a heart attack at age 60. The client has indigestion. The nurse connects him to an electrocardiogram monitor and begins administering oxygen at 2 L/min via nasal cannula. What should the nurse do next?
- A. Call for the physician.
- B. Start an IV infusion.
- C. Obtain a portable chest radiograph.
- D. Draw blood for laboratory studies.
Correct answer: B
Rationale: In a client presenting with possible myocardial infarction who is receiving oxygen therapy and cardiac monitoring, the next priority action is to establish IV access by starting an IV infusion. This allows for prompt administration of medications and fluids as needed in the management of acute coronary syndromes. Calling the physician (Choice A) may be necessary but is not the immediate next step. Obtaining a portable chest radiograph (Choice C) may help in further assessment but is not as crucial as establishing IV access. Drawing blood for laboratory studies (Choice D) is important for diagnostic purposes but is not as urgent compared to starting an IV infusion in the setting of a potential myocardial infarction.
4. Which of the following is a common cause of acute kidney injury?
- A. Hypertension
- B. Dehydration
- C. Infection
- D. Hypotension
Correct answer: C
Rationale: Infection is a common cause of acute kidney injury because when the body fights an infection, it activates the immune response, leading to inflammation. This inflammatory response can affect the kidneys and impair their function. While hypertension (choice A) is a risk factor for chronic kidney disease, it is not a direct cause of acute kidney injury. Dehydration (choice B) can lead to prerenal acute kidney injury due to decreased blood flow to the kidneys, but infection is a more common cause of acute kidney injury. Hypotension (choice D) can contribute to prerenal acute kidney injury, but it is not a direct cause like infection.
5. A client with a diagnosis of hypothermia is being admitted to the hospital by a nurse. Which of the following signs does the nurse anticipate that this client will exhibit?
- A. Increased heart rate and increased blood pressure
- B. Increased heart rate and decreased blood pressure
- C. Decreased heart rate and increased blood pressure
- D. Decreased heart rate and decreased blood pressure
Correct answer: D
Rationale: Hypothermia decreases the heart rate and blood pressure due to reduced metabolic needs of the body. With lower metabolic demands, the heart's workload decreases, leading to reductions in both heart rate and blood pressure. Choices A, B, and C are incorrect because hypothermia typically results in a decrease in heart rate and blood pressure, not an increase.
