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. A client has had a pulmonary artery catheter inserted. In performing hemodynamic monitoring with the catheter, the nurse will wedge the catheter to gain information about which of the following?

• A. Cardiac output.
• B. Right atrial blood flow.
• C. Left end-diastolic pressure.
• D. Cardiac index.

Correct answer: C

Rationale: The correct answer is C: Left end-diastolic pressure. Wedging the pulmonary artery catheter allows the nurse to obtain the pulmonary artery wedge pressure, which reflects the left end-diastolic pressure. This pressure is essential in assessing left ventricular function and diagnosing conditions like heart failure. Choices A, B, and D are incorrect because wedging the catheter does not directly provide information about cardiac output, right atrial blood flow, or cardiac index.

3. A nurse cares for a client with diabetes mellitus who is prescribed metformin (Glucophage) and is scheduled for an intravenous urography. Which action should the nurse take first?

• A. Contact the provider and recommend discontinuing the metformin.
• B. Keep the client NPO for at least 6 hours prior to the examination.
• C. Check the client’s capillary artery blood glucose and administer prescribed insulin.
• D. Administer intravenous fluids to dilute and increase the excretion of dye.

Correct answer: A

Rationale: Metformin can cause lactic acidosis and renal impairment as the result of an interaction with the dye. This drug must be discontinued for 48 hours before the procedure and not started again after the procedure until urine output is well established. The client’s health care provider needs to provide alternative therapy for the client until the metformin can be resumed. Keeping the client NPO, checking the client’s blood glucose, and administering intravenous fluids should be part of the client’s plan of care, but are not the priority, as the examination should not occur while the client is still taking metformin.

4. The healthcare provider is assessing a client with chronic renal failure who is receiving peritoneal dialysis. Which of the following findings would indicate a complication of the treatment?

• A. Clear dialysate outflow.
• B. Cloudy dialysate outflow.
• C. Decreased urine output.
• D. Increased blood pressure.

Correct answer: B

Rationale: Cloudy dialysate outflow is a sign of peritonitis, a serious complication of peritoneal dialysis that requires immediate medical attention. Peritonitis, an infection of the peritoneum, the lining of the abdominal cavity, can lead to severe complications if not treated promptly. Clear dialysate outflow is an expected finding in peritoneal dialysis, indicating proper functioning of the process. Decreased urine output is common in clients with renal failure due to impaired kidney function. Increased blood pressure may be present in renal failure but is not a direct complication of peritoneal dialysis.

5. The nurse is preparing to give a dose of oral clindamycin (Cleocin) to a patient being treated for a skin infection caused by Staphylococcus aureus. The patient has experienced nausea after several doses. What should the nurse do next?

• A. Administer the next dose when the patient has an empty stomach.
• B. Hold the next dose and contact the patient’s provider.
• C. Instruct the patient to take the next dose with a full glass of water.
• D. Request an order for an antacid to give along with the next dose.

Correct answer: C

Rationale: The correct action for the nurse to take next is to instruct the patient to take the next dose of clindamycin with a full glass of water. This is important to minimize gastrointestinal (GI) irritation such as nausea, vomiting, and stomatitis that the patient has been experiencing. Administering the medication on an empty stomach would likely worsen the GI upset. Holding the next dose and contacting the provider is not necessary at this point unless symptoms persist or worsen. Additionally, requesting an antacid is not indicated as the primary intervention for managing the nausea related to clindamycin.
