1. When should a blood sample be obtained for a peak serum level of gentamicin when administered by IV infusion for 1 hour at 0900?
- A. 1000
- B. 1030
- C. 1100
- D. 1130
Correct answer: B
Rationale: The nurse should obtain the blood sample for the peak serum level at 1030. This timing allows for 30 minutes to elapse after the completion of the 1-hour IV infusion, which is the recommended window for obtaining the peak serum level of gentamicin.
2. What is the antidote for copper toxicity?
- A. Glucagon
- B. Aminocaproic acid
- C. Atropine
- D. Penicillamine
Correct answer: D
Rationale: Penicillamine is the specific chelating agent used for copper toxicity. It forms stable complexes with copper, which are then excreted in the urine. Glucagon is used for treating hypoglycemia, aminocaproic acid is used to treat bleeding disorders, and atropine is used as an antidote for certain types of poisoning, such as organophosphate toxicity.
3. What is levothyroxine's pharmacologic classification?
- A. Thyroid Preparations
- B. Metabolic Inhibitors
- C. Analgesic
- D. Loop Diuretic
Correct answer: A
Rationale: Levothyroxine is classified as a thyroid preparation because it is a synthetic form of the thyroid hormone thyroxine. It is primarily used to treat hypothyroidism by supplementing or replacing the natural thyroid hormones in the body, helping to regulate metabolism and energy levels. Choice B, Metabolic Inhibitors, is incorrect because levothyroxine does not inhibit metabolism but rather helps regulate it. Choice C, Analgesic, is incorrect as levothyroxine is not used for pain relief but for thyroid hormone replacement therapy. Choice D, Loop Diuretic, is also incorrect as loop diuretics are medications that act on the kidneys to increase urine production and are not related to thyroid hormone replacement therapy.
4. A client is prescribed Clopidogrel. Which of the following laboratory values should be monitored to assess for potential adverse effects?
- A. White blood cell count
- B. Platelet count
- C. Hemoglobin
- D. Blood glucose
Correct answer: B
Rationale: Clopidogrel is an antiplatelet medication, so monitoring the client's platelet count is crucial to assess for potential bleeding complications. Changes in platelet count can indicate an increased risk of bleeding, a known adverse effect of Clopidogrel. Monitoring white blood cell count, hemoglobin, or blood glucose is not directly related to the potential adverse effects of Clopidogrel and would not provide relevant information regarding the medication's impact on platelet function.
5. A client with a urinary tract infection (UTI) is prescribed ciprofloxacin. Which instruction should the nurse provide to the client?
- A. If the medication causes an upset stomach, take an antacid at the same time.
- B. Increase your daily fluid intake while taking this medication.
- C. This medication can cause photophobia, so avoid direct sunlight exposure.
- D. You should report any tendon discomfort you experience while taking this medication.
Correct answer: D
Rationale: The correct answer is D. Tendon discomfort is a potential side effect of ciprofloxacin that can lead to tendon rupture and should be reported immediately to prevent serious complications. Monitoring for this adverse effect is crucial for patient safety. Choices A, B, and C are incorrect because: A) Taking an antacid with ciprofloxacin can interfere with its absorption. B) Increasing fluid intake is generally a good recommendation but not specifically related to the side effects of ciprofloxacin. C) Photophobia is not a common side effect of ciprofloxacin; therefore, avoiding direct sunlight exposure is not necessary.
