A patient at a rehabilitation center is prescribed erythromycin. The nurse is reviewing the patient's medication list, checking to see if there are medications that should not be taken with this antibiotic. One medication is found. What medication should not be taken with erythromycin?
Ibuprofen
Lasix
Lovastatin
Lisinopril
The Correct Answer is C
A. Ibuprofen:
Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) commonly used to relieve pain and reduce inflammation. There are no significant interactions reported between erythromycin and ibuprofen.
B. Lasix (Furosemide):
Lasix is a diuretic medication used to treat fluid retention (edema) and high blood pressure. There are no significant interactions reported between erythromycin and furosemide.
C. Lovastatin:
Lovastatin is a statin medication used to lower cholesterol levels. Erythromycin can increase the levels of lovastatin in the blood by inhibiting its metabolism through the CYP3A4 enzyme. This can lead to an increased risk of statin-related side effects, including muscle pain and weakness, and in rare cases, rhabdomyolysis.
D. Lisinopril:
Lisinopril is an angiotensin-converting enzyme (ACE) inhibitor used to treat high blood pressure and heart failure. There are no significant interactions reported between erythromycin and lisinopril.

Correct Answer is B
Explanation
A. Penicillins:
Penicillins are a class of antibiotics commonly used to treat various bacterial infections. While they are generally well-tolerated and have a low incidence of adverse effects, they are not typically associated with cartilage toxicity or tendon rupture, including the Achilles tendon.
B. Fluoroquinolones:
Fluoroquinolones are broad-spectrum antibiotics known for their effectiveness against a wide range of bacteria. However, they are associated with several significant adverse effects, including cartilage toxicity and tendon rupture. These adverse effects, particularly tendon rupture, are most commonly observed in weight-bearing tendons such as the Achilles tendon. Fluoroquinolones should be used cautiously, especially in populations at higher risk for tendon injuries.
C. Aminoglycosides:
Aminoglycosides are another class of antibiotics used to treat severe bacterial infections. While they have their own set of potential adverse effects, such as nephrotoxicity and ototoxicity, they are not associated with cartilage toxicity or tendon rupture.
D. Sulfonamides:
Sulfonamides are antibiotics that inhibit bacterial growth by interfering with the synthesis of folate. While they can cause various adverse effects, including skin reactions and hematologic abnormalities, they are not associated with cartilage toxicity or tendon rupture.
Correct Answer is ["0.6"]
Explanation
To calculate the volume of diazepam solution needed, we can use the formula:
Volume (mL) = Total dose (mg) / Concentration (mg/mL)
Given:
Total dose = 3 mg
Concentration = 5 mg/mL
Plugging the values into the formula:
Volume (mL) = 3 mg / 5 mg/mL
Volume (mL) = 0.6 mL
The nurse should administer: 0.6 mL
