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. In the staging process of Hodgkin's disease, what does Stage I indicate?
- A. Involvement of a single lymph node.
- B. Involvement of two or more lymph nodes on the same side of the diaphragm.
- C. Involvement of lymph node regions on both sides of the diaphragm.
- D. Involvement of diffuse disease of one or more extralymphatic organs.
Correct answer: A
Rationale: In the staging process of Hodgkin's disease, Stage I signifies the involvement of a single lymph node. This stage indicates localized disease with the disease being limited to a single lymph node or a group of adjacent nodes. Choices B, C, and D are incorrect because they describe more extensive involvement of lymph nodes, both sides of the diaphragm, or extralymphatic organs, which would correspond to higher stages in the staging system.
3. What is an ideal goal of treatment set by the nurse in the care plan for a client diagnosed with chronic kidney disease (CKD) to reduce the risk of pulmonary edema?
- A. Maintaining oxygen saturation above 92%
- B. Absence of crackles and wheezes in lung sounds
- C. Maintaining a balanced intake and output
- D. Absence of shortness of breath at rest
Correct answer: C
Rationale: The ideal goal of treatment for a client with chronic kidney disease (CKD) to reduce the risk of pulmonary edema is to maintain a balanced intake and output. This helps in achieving optimal fluid balance, enabling the heart to eject blood effectively without increasing pressure in the left ventricle and pulmonary vessels. While maintaining oxygen saturation above 92% is important for adequate tissue oxygenation, the primary focus in this scenario is fluid balance. Absence of crackles and wheezes in lung sounds is important to assess for pulmonary status, but it is not the primary goal to prevent pulmonary edema specifically. Similarly, absence of shortness of breath at rest is a relevant goal, but the emphasis in CKD management is on fluid balance to prevent pulmonary complications.
4. After a lumbar puncture, into which position does the nurse assist the client?
- A. Flat
- B. Semi-Fowler
- C. Side-lying with the head of the bed elevated
- D. Sitting up in a recliner with the feet elevated
Correct answer: A
Rationale: After a lumbar puncture, the client should be positioned flat. This position helps prevent post-procedure spinal headaches and cerebrospinal fluid leakage. Keeping the client flat for up to 12 hours is crucial in minimizing these risks. Choices B, C, and D are incorrect because elevating the head of the bed or sitting up can increase the risk of complications by altering the pressure in the spinal canal, potentially leading to headaches and fluid leakage.
5. A healthcare professional is reviewing the results of renal function testing in a client with renal calculi. Which finding indicates to the healthcare professional that the client’s blood urea nitrogen (BUN) level is within the normal range?
- A. 2 mg/dL
- B. 18 mg/dL
- C. 25 mg/dL
- D. 35 mg/dL
Correct answer: B
Rationale: The normal BUN ranges from 5 to 20 mg/dL. A BUN level of 18 mg/dL falls within this normal range. Values of 25 and 35 mg/dL are elevated, suggesting potential renal insufficiency. Choice A (2 mg/dL) is abnormally low and not indicative of a normal BUN level.
