The healthcare provider prescribes enoxaparin sodium 80 mg SUBQ three times daily. The nurse is preparing a preloaded 1 mL syringe labeled “Enoxaparin sodium injection, USP 60 mg/0.6 mL.”

How many mL should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest tenth.)

Choice A reason: A complete blood count (CBC) is not typically required before starting statin therapy. While a CBC can provide valuable information about a patient’s overall health, it does not specifically relate to the potential side effects or necessary monitoring for statin use. Statins primarily affect the liver, so monitoring liver function is more critical.

Choice B reason: Serum electrolytes are important for assessing overall metabolic and kidney function, but they are not directly related to the initiation of statin therapy. Statins do not typically affect electrolyte levels, so this test is not necessary before starting the medication.

Choice C reason: Capillary blood glucose levels are important for monitoring diabetes and blood sugar control. While statins can have an impact on blood glucose levels, this is not the primary concern when initiating therapy. Monitoring liver function is more directly related to the potential side effects of statins.

Choice D reason: Serum liver enzymes are crucial to review before starting statin therapy. Statins can cause liver enzyme elevations, indicating liver damage or dysfunction. Therefore, baseline liver enzyme levels should be obtained to monitor for any potential hepatotoxicity during treatment.

Choice A reason: Withholding the scheduled dose and notifying the healthcare provider is the correct action because the client’s heart rate is significantly low at 48 beats per minute. Labetalol, a beta-blocker, can further reduce the heart rate, potentially leading to bradycardia or other cardiac complications. It is crucial to inform the healthcare provider to reassess the medication regimen and ensure the client’s safety.

Choice B reason: Administering the dose and monitoring the client’s blood pressure regularly is not advisable in this scenario. Although monitoring blood pressure is important, the primary concern here is the client’s low heart rate. Administering labetalol could exacerbate bradycardia, leading to severe complications.

Choice C reason: Assessing for orthostatic hypotension before administering the dose is a good practice but not the most critical action in this situation. The client’s low heart rate poses a more immediate risk than orthostatic hypotension. Therefore, withholding the medication and notifying the healthcare provider is a higher priority.

Choice D reason: Applying a telemetry monitor before administering the dose is useful for continuous cardiac monitoring, but it does not address the immediate concern of the client’s low heart rate. The priority should be to withhold the medication and consult the healthcare provider to prevent potential bradycardia.
