A nurse is preparing to administer vancomycin 50 mg PO daily divided into four equal doses. The amount available is vancomycin 125 mg capsules. How many capsules should the nurse administer with each dose?

(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A reason:

Erythromycin is a macrolide antibiotic and is generally considered safe for patients with a penicillin allergy. It does not share the beta-lactam ring structure that is responsible for cross-reactivity in penicillin-allergic patients.

Choice B reason:

Gentamicin is an aminoglycoside antibiotic and is also safe for patients with a penicillin allergy. It does not have the beta-lactam ring structure and therefore does not pose a risk of cross-reactivity.

Choice C reason:

Amphotericin B is an antifungal medication and is not related to penicillin. It is safe for use in patients with a penicillin allergy as it does not share any structural similarities with penicillin.

Choice D reason:

Amoxicillin-clavulanate is a combination of a penicillin antibiotic (amoxicillin) and a beta-lactamase inhibitor (clavulanate). Since it contains amoxicillin, it should not be given to patients with a penicillin allergy due to the risk of an allergic reaction.

Choice A reason: The procedure will be cancelled if the urinalysis indicates the presence of red blood cells

This statement is incorrect. The presence of red blood cells in the urine does not necessarily cancel an intravenous pyelogram (IVP). The test is often used to diagnose conditions that might cause blood in the urine, such as kidney stones or tumors. Therefore, this statement does not accurately reflect the procedure’s protocol.

Choice B reason: You will be able to resume your regular diet as soon as the test is complete

This statement is correct. After an IVP, clients can typically resume their regular diet unless otherwise instructed by their healthcare provider. However, this is not the most critical piece of information for the client to understand about the procedure.

Choice C reason: High-frequency sound waves will be used to identify renal system structures

This statement is incorrect. An IVP uses X-rays and a contrast dye to visualize the urinary tract, not high-frequency sound waves. High-frequency sound waves are used in ultrasound imaging, which is a different diagnostic procedure.

Choice D reason: After the procedure, you will be encouraged to drink plenty of fluids

This statement is correct and important. After an IVP, clients are encouraged to drink plenty of fluids to help flush the contrast dye out of their system and reduce the risk of kidney damage. This is a crucial part of post-procedure care and should be emphasized to the client.
