A nurse is preparing to administer levothyroxine 100 mcg orally to a patient with hypothyroidism. The available levothyroxine is in 50 mcg tablets.
How many tablets should the nurse administer?

Choice A rationale
Withholding the medication until the prescribing provider is available could potentially put the patient at risk, especially if the medication is critical for the patient’s health and well-being.
Choice B rationale
Requesting to speak with the provider who is covering for the prescriber is the most appropriate action in this situation. This allows the nurse to clarify the prescription and ensure the safety of the patient.

Choice C rationale
Contacting the pharmacy to confirm that the dosage is safe to administer could be a part of the process, but it should not be the first step. The nurse should first contact a healthcare provider to discuss the prescription.
Choice D rationale
Informing the charge nurse and administering the usual dose of the medication without first consulting with a healthcare provider could potentially put the patient at risk.

Choice A rationale
Applying the pulse oximeter probe to the toe might not provide an accurate reading if the client has poor peripheral circulation. Additionally, thickened toenails can interfere with the reading.
Choice B rationale

Edema in the hands can affect the accuracy of a pulse oximeter reading. The probe might not fit properly or provide a reliable reading if the finger is swollen.
Choice C rationale
Applying the pulse oximeter probe to a skin fold is not recommended. The probe needs to be placed on a relatively flat, thin area of skin to accurately measure oxygen saturation.
Choice D rationale
The earlobe is a suitable alternative site for pulse oximetry if the fingers and toes are not viable options. The earlobe is typically less affected by peripheral vasoconstriction, which can occur with hypothermia, certain medications, and certain diseases. Therefore, Choice D is the correct answer.
