A nurse is caring for a client who has been taking epoetin alfa for 3 months.
Which of the following laboratory tests should the nurse monitor to determine the effectiveness of the medication?

Choice A rationale:

Rifampin does not typically cause insomnia.

Choice B rationale:

Rifampin can cause a red or orange discoloration of body fluids, including urine, not blue or green.

Choice C rationale:

It is recommended to take rifampin on an empty stomach, either 1 hour before or 2 hours after a meal.

Choice D rationale:

Unusual hair growth is not a known side effect of rifampin.

Choice A rationale:

The gauge and length of needle used for an IM injection are important to document. This information can help track which supplies were used and can be useful for future reference.

Choice B rationale:

While it’s important to check the medication expiration date before administration, it’s not typically documented after administering medication.

Choice C rationale:

The dose of medication administered should always be documented. This helps ensure accurate medical records and allows healthcare providers to track how much of a medication a patient has received.

Choice D rationale:

The site of injection should be documented. This can help prevent complications such as repeated use of the same injection site.

Choice E rationale:

The time of administration should be documented. This helps keep track of when the patient received their medication, which is crucial for medications that need to be given at specific intervals.
