The health care provider prescribes the antibiotic tetracycline HCl for an adult client who arrived at an outpatient clinic. Which instruction should the nurse include in the teaching plan for this client?

Choice A reason: A yellow skin color may indicate jaundice, which is a sign of liver damage. Acetaminophen can cause liver toxicity, especially in high doses or with chronic use. The nurse should report this finding to the healthcare provider as soon as possible, as it may require further evaluation and treatment.

Choice B reason: Checking the client's capillary glucose level is not relevant to the finding of yellow skin color. Although diabetes can cause skin changes, such as dryness or infections, it does not cause jaundice. The nurse should focus on the potential liver problem rather than the blood sugar level.

Choice C reason: Using a pulse oximeter to assess oxygen saturation is not helpful in this situation. A low oxygen saturation may indicate hypoxia, which can affect various organs, but it does not cause jaundice. The nurse should monitor the client's respiratory status, but it is not the priority action in response to the yellow skin color.

Choice D reason: Advising the client to reduce the medication dose is not appropriate without consulting the healthcare provider. The client may need acetaminophen for pain relief, and reducing the dose may not be enough to prevent liver damage. The nurse should not make any changes to the medication regimen without the provider's order.

Choice A reason: Assessing for orthostatic hypotension is not a priority action before administering labetalol. Orthostatic hypotension is a possible side effect of the drug, but it is not an immediate concern.

Choice B reason: Administering the dose and monitoring the client's BP regularly is not the best action. The client's heart rate is below the normal range of 60 to 100 beats/minute, which indicates bradycardia. Labetalol can further lower the heart rate and cause cardiac complications.

Choice C reason: Applying a telemetry monitor before administering the dose is not necessary. Telemetry monitoring is used to detect cardiac arrhythmias, which are not a common adverse effect of labetalol. The client's heart rate and rhythm should be assessed by auscultation.

Choice D reason: Withholding the scheduled dose and notifying the health care provider is the correct action. The client's heart rate is too low to safely receive labetalol, which is a beta-blocker that can decrease the heart rate and contractility. The health care provider should be informed of the client's vital signs and the need to adjust the medication dosage or frequency.
