A female patient who is allergic to penicillin will begin taking an antibiotic to treat a lower respiratory tract infection. The patient tells the nurse that she almost always develops a vaginal yeast infection when she takes antibiotics and that she will take fluconazole (Diflucan) with the antibiotic being prescribed. Which macrolide should the nurse question for this patient?
- A. Azithromycin (Zithromax)
- B. Clarithromycin (Biaxin)
- C. Erythromycin (E-Mycin)
- D. Fidaxomicin (Dificid)
Correct Answer: C
Rationale: The nurse should question the prescription of erythromycin for this patient. When erythromycin is given concurrently with fluconazole, erythromycin blood concentration and the risk of sudden cardiac death increase. Therefore, it is not recommended to use erythromycin in combination with fluconazole for this patient. Azithromycin, clarithromycin, and fidaxomicin are alternative macrolide antibiotics that can be considered for this patient without the same risk of interactions when used with fluconazole.

A client with chronic kidney disease (CKD) is experiencing nausea, vomiting, visual changes, and anorexia. Which action by the nurse is best?
- A. Check the client's digoxin (Lanoxin) level.
- B. Administer an anti-nausea medication.
- C. Ask if the client can eat crackers.
- D. Refer the client to a gastrointestinal specialist.
Correct Answer: A
Rationale: In a client with chronic kidney disease experiencing symptoms like nausea, vomiting, visual changes, and anorexia, it is crucial for the nurse to suspect digoxin (Lanoxin) toxicity. These symptoms are indicative of digoxin toxicity. Therefore, the best action for the nurse to take is to check the client's digoxin level. Administering anti-nausea medication, asking about eating crackers, and referring to a gastrointestinal specialist may help with symptom management but do not address the underlying cause of the symptoms, which is digoxin toxicity in this case.
A client's urinalysis results show a urine osmolality of 1200 mOsm/L. What action should the nurse take?
- A. Encourage the client to drink more fluids.
- B. Contact the provider and recommend a low-sodium diet.
- C. Prepare to administer an intravenous diuretic.
- D. Obtain a suction device and implement seizure precautions.
Correct Answer: A
Rationale: The correct action for the nurse to take when the client has a urine osmolality of 1200 mOsm/L, indicating dehydration, is to encourage the client to drink more fluids. Dehydration can lead to elevated urine osmolality, and increasing fluid intake can help rehydrate the client. A low-sodium diet is not the priority in this scenario as it would not directly address the dehydration indicated by the high urine osmolality. Administering an intravenous diuretic would further concentrate the urine, exacerbating the dehydration. Obtaining a suction device and implementing seizure precautions are not indicated based on the client's urine osmolality results and would not address the underlying issue of dehydration.
A nurse is assessing the status of a client with diabetes mellitus. The nurse concludes that the client is exhibiting adequate diabetic control if the serum level of glycosylated hemoglobin A1C (HbA1C) is less than:
- A. 7%
- B. 9%
- C. 10%
- D. 15%
Correct Answer: A
Rationale: The correct answer is A: 7%. Glycosylated hemoglobin A1C (HbA1C) level of 7.0% or less is considered indicative of adequate diabetic control. This level reflects good long-term blood sugar management. Choices B, C, and D are incorrect because an HbA1C level above 7% indicates poor diabetic control and an increased risk of complications associated with diabetes, such as cardiovascular disease, neuropathy, and retinopathy.
After educating a client with a history of renal calculi, the nurse assesses the client's understanding. Which statement made by the client indicates a correct understanding of the teaching?
- A. I should drink at least 3 liters of fluid every day.
- B. I will eliminate all dairy or sources of calcium from my diet.
- C. Aspirin and aspirin-containing products can lead to stones.
- D. The doctor can give me antibiotics at the first sign of a stone.
Correct Answer: A
Rationale: To prevent the formation of renal calculi, it is essential to maintain adequate hydration as dehydration can contribute to the precipitation of minerals leading to stone formation. Therefore, the correct statement indicating understanding of the teaching is choice A. Increasing fluid intake helps dilute urine and reduces the risk of stone formation. Eliminating all sources of calcium is not recommended as calcium is essential for various bodily functions and eliminating it can lead to other health issues. Aspirin and aspirin-containing products do not directly cause kidney stones. Antibiotics are not used to prevent or treat renal calculi, as they are not caused by bacterial infections.
When a patient starts taking amoxicillin, which foods should the nurse instruct the patient to avoid?
- A. Green leafy vegetables
- B. Beef and other red meat
- C. Coffee, tea, and colas
- D. Acidic fruits and juices
Correct Answer: D
Rationale: The correct answer is D: Acidic fruits and juices. Amoxicillin can be irritating to the stomach, so avoiding acidic fruits and juices is recommended to reduce stomach discomfort or potential interactions. Green leafy vegetables (Choice A), beef and other red meat (Choice B), and coffee, tea, and colas (Choice C) are not typically contraindicated with amoxicillin. It is important to focus on acidic foods and beverages to promote comfort and effectiveness of the medication.
