Nursing Elites

1. A patient is diagnosed with Mycoplasma pneumonia. Which antibiotic will the nurse expect the provider to order to treat this infection?

• A. Azithromycin (Zithromax)
• B. Clarithromycin (Biaxin)
• C. Erythromycin (E-Mycin)
• D. Fidaxomicin (Dificid)

Correct answer: C

Rationale: Erythromycin is the drug of choice for treating Mycoplasma pneumonia. Mycoplasma pneumonia is typically sensitive to macrolide antibiotics, with erythromycin being one of the first-line agents. Azithromycin and clarithromycin are also effective in treating Mycoplasma pneumonia, but erythromycin is specifically mentioned as the drug of choice in this context. Fidaxomicin, on the other hand, is not indicated for the treatment of Mycoplasma pneumonia and is primarily used to treat Clostridium difficile infections.

2. The patient has a heart rate of 98 beats per minute and a blood pressure of 82/58 mm Hg, is lethargic, complaining of muscle weakness, and has had gastroenteritis for several days. Based on these findings, which sodium value would the nurse expect?

• A. 126 mEq/L
• B. 140 mEq/L
• C. 145 mEq/L
• D. 158 mEq/L

Correct answer: A

Rationale: The patient's presentation of tachycardia, hypotension, lethargy, muscle weakness, and gastroenteritis suggests hyponatremia. Hyponatremia is characterized by a serum sodium level below the normal range of 135-145 mEq/L. A serum sodium level of 126 mEq/L falls significantly below this range, indicating hyponatremia. Choice B (140 mEq/L) and Choice C (145 mEq/L) are within the normal range for serum sodium levels and would not explain the patient's symptoms. Choice D (158 mEq/L) is above the normal range and would indicate hypernatremia, which is not consistent with the patient's presentation.

3. A client arrived to the medical-surgical unit 4 hours after a transurethral resection of the prostate (TURP). A triple-lumen catheter for continuous bladder irrigation with normal saline is infusing, and the nurse observes dark, pink-tinged outflow with blood clots in the tubing and collection bag. Which action should the nurse take?

• A. Monitoring catheter drainage
• B. Decreasing the flow rate
• C. Irrigating the catheter manually
• D. Discontinuing infusing the solution

Correct answer: C

Rationale: In this scenario, the nurse should choose option C - irrigating the catheter manually. This action can help clear the clots from the catheter and ensure proper bladder drainage. Monitoring catheter drainage (option A) alone may not address the issue of clots obstructing the flow. Decreasing the flow rate (option B) could potentially worsen clot formation. Discontinuing the infusing solution (option D) without addressing the clots first may lead to inadequate irrigation and increase the risk of complications.

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. The healthcare provider is caring for a 7-year-old patient who will receive oral antibiotics. Which antibiotic order will the healthcare provider question for this patient?

• A. Azithromycin (Zithromax)
• B. Clarithromycin (Biaxin)
• C. Clindamycin (Cleocin)
• D. Tetracycline (Sumycin)

Correct answer: D

Rationale: The correct answer is D, Tetracycline (Sumycin). Tetracyclines should not be given to children younger than 8 years of age because they irreversibly discolor the permanent teeth. Azithromycin, Clarithromycin, and Clindamycin are antibiotics that are generally safe for use in children and do not have the same tooth discoloration side effect as Tetracycline. Therefore, these antibiotics would be more appropriate choices for a 7-year-old patient.
