Question 1 of 5
A patient is diagnosed with Mycoplasma pneumonia. Which antibiotic will the nurse expect the provider to order to treat this infection?
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.
Question 2 of 5
The nurse is preparing to administer intravenous gentamicin to an infant through an intermittent needle. The nurse notes that the infant has not had a wet diaper for several hours. The nurse will perform which action?
Correct Answer: D
Rationale: In this scenario, the infant not having a wet diaper for several hours indicates a potential decrease in urine output, which can be a sign of nephrotoxicity related to gentamicin. The correct action for the nurse is to hold the dose and contact the provider to request a serum trough drug level. This is important to monitor the drug levels and ensure that they are not reaching toxic levels. Administering the medication without addressing the decreased urine output could potentially lead to further nephrotoxicity. Contacting the provider to add intravenous fluids or obtaining a serum peak drug level are not the most appropriate actions in this situation as the priority is to assess for potential nephrotoxicity and ensure patient safety.
Question 3 of 5
The nurse is caring for a patient who is taking trimethoprim-sulfamethoxazole (TMP-SMX). The nurse learns that the patient takes an angiotensin-converting enzyme (ACE) inhibitor. To monitor for drug interactions, the nurse will request an order for which laboratory test(s)?
Correct Answer: C
Rationale: The correct answer is 'C. Electrolytes.' When trimethoprim-sulfamethoxazole (TMP-SMX) is taken with an ACE inhibitor, there is an increased risk of hyperkalemia due to the combined effects on potassium levels. Monitoring electrolytes, specifically potassium, is essential to detect and manage this potential drug interaction. Choices A, B, and D are incorrect because while they are important tests in general patient care, they are not specifically indicated to monitor for the drug interaction between TMP-SMX and ACE inhibitors.
Question 4 of 5
The nurse is caring for a patient who develops marked edema and a low urine output as a result of heart failure. Which medication will the nurse expect the provider to order for this patient?
Correct Answer: B
Rationale: In heart failure with marked edema and low urine output, the nurse can expect the provider to order Furosemide (Lasix). Furosemide is a loop diuretic that acts quickly to remove excess fluid from the body, making it an appropriate choice for this patient's condition. Digoxin is used to improve heart function but does not directly address fluid overload. Hydrochlorothiazide is a thiazide diuretic that is not as potent as Furosemide in managing acute fluid retention. Spironolactone is a potassium-sparing diuretic that is typically used in heart failure for its aldosterone-blocking effects and not for immediate fluid removal.
Question 5 of 5
The patient is taking hydrochlorothiazide (HydroDIURIL) and digoxin (Lanoxin). Which potential electrolyte imbalance will the nurse monitor for in this patient?
Correct Answer: D
Rationale: The correct answer is D: Hypokalemia. Thiazide diuretics like hydrochlorothiazide can cause hypokalemia. Hypokalemia enhances the effects of digoxin, leading to digoxin toxicity. Thiazides can also cause hypercalcemia. Choices A, B, and C are incorrect. Hypermagnesemia is not typically associated with hydrochlorothiazide use. Hypernatremia and hypocalcemia are not the primary electrolyte imbalances to monitor for in this scenario.
