1. The nurse is caring for a patient who is receiving an intravenous antibiotic. The nurse notes that the provider has ordered serum drug peak and trough levels. The nurse understands that these tests are necessary for which type of drugs?
- A. Drugs with a broad spectrum
- B. Drugs with a narrow spectrum
- C. Drugs with a broad therapeutic index
- D. Drugs with a narrow therapeutic index
Correct answer: D
Rationale: Medications with a narrow therapeutic index have a limited range between the therapeutic dose and a toxic dose. It is important to monitor these medications closely by evaluating regular serum peak and trough levels. Drugs with a narrow spectrum (Choice B) are antibiotics that target only a limited group of bacteria, not related to the need for peak and trough monitoring. Drugs with a broad spectrum (Choice A) cover a wide range of bacteria, but this characteristic does not determine the need for peak and trough monitoring. Drugs with a broad therapeutic index (Choice C) have a wide safety margin between therapeutic and toxic doses, so they typically do not require peak and trough level monitoring.
2. The nurse is teaching the main principles of hemodialysis to a client with chronic kidney disease. Which statement by the client indicates a need for further teaching by the nurse?
- A. My sodium level changes due to the movement from the blood into the dialysate.
- B. Dialysis works by the movement of wastes from higher to lower concentration.
- C. Extra fluid can be pulled from the blood by osmosis.
- D. The dialysate is similar to blood but without any toxins.
Correct answer: B
Rationale: The correct answer is B because dialysis works by the movement of solutes from an area of higher concentration to an area of lower concentration, which is known as diffusion. The other statements are accurate: A correctly describes the movement of sodium during hemodialysis, C explains the removal of excess fluid by osmosis, and D highlights the purpose of the dialysate in removing toxins from the blood.
3. The nurse observes an increased number of blood clots in the drainage tubing of a client with continuous bladder irrigation following a transurethral resection of the prostate (TURP). What is the best initial nursing action?
- A. Provide additional oral fluid intake
- B. Measure the client's intake and output
- C. Increase the flow of the bladder irrigation
- D. Administer a PRN dose of an antispasmodic agent
Correct answer: C
Rationale: The best initial nursing action when observing an increased number of blood clots in the drainage tubing of a client with continuous bladder irrigation post-TURP is to increase the flow of the bladder irrigation. This action helps prevent blood clots from obstructing the catheter, ensuring effective drainage and promoting client comfort. Providing additional oral fluid intake (Choice A) is important for overall hydration but may not directly address the issue of blood clots in the drainage tubing. Measuring the client's intake and output (Choice B) is a routine nursing assessment that may not directly address the immediate concern of blood clots obstructing the catheter. Administering a PRN dose of an antispasmodic agent (Choice D) is not the best initial action as it does not directly address the issue of blood clots in the drainage tubing.
4. A patient with a diagnosis of Cushing's syndrome is likely to exhibit which of the following symptoms?
- A. Hyperpigmentation.
- B. Moon face.
- C. Hypotension.
- D. Hypertension.
Correct answer: B
Rationale: The correct answer is B: Moon face. Cushing's syndrome is characterized by excess cortisol levels, leading to the distinctive round and full face known as moon face. Hyperpigmentation (choice A) may occur due to increased ACTH levels, but it is not a hallmark symptom like moon face. Hypotension (choice C) is less common in Cushing's syndrome as cortisol typically leads to hypertension (choice D) due to its effects on blood pressure regulation.
5. The nurse explains to the client with Hodgkin's disease that a bone marrow biopsy will be taken after the aspiration. What should the nurse explain about the biopsy?
- A. The biopsy will confirm the diagnosis of Hodgkin's disease.
- B. The biopsy will show the extent of the disease in the bones.
- C. The biopsy will be done to check for infection in the bones.
- D. The biopsy will help determine the best treatment for the disease.
Correct answer: D
Rationale: A bone marrow biopsy helps determine the best treatment plan for Hodgkin's disease by providing crucial information about the extent and nature of the disease. While confirming the diagnosis is important, the primary purpose of the biopsy in this case is to guide treatment decisions. The biopsy is not primarily for assessing the extent of the disease in the bones or checking for infections in the bones.
