A nurse is caring for a client who has a prescription for epoetin alfa. Which of the following routes should the nurse plan to use for administration?
Oral
Subcutaneous
Transdermal
Intranasal
The Correct Answer is B
B. Epoetin alfa is often administered subcutaneously to provide a slow and sustained release of the medication into the bloodstream. Subcutaneous administration allows for easy access to fatty tissue beneath the skin and provides a suitable absorption rate for the medication.
A. Epoetin alfa is a protein-based medication that would be broken down by digestive enzymes in the gastrointestinal tract, rendering it ineffective if taken orally. Therefore, oral administration is not suitable for epoetin alfa.
C. Epoetin alfa molecules are too large to pass through the skin barrier effectively. Transdermal delivery systems are typically used for medications that are small, lipid-soluble, and can penetrate the skin's layers to enter the bloodstream.
D. Epoetin alfa is not formulated for absorption through nasal mucosa. Intranasal administration is generally reserved for medications that can be absorbed through the nasal membranes, such as certain hormones or medications for nasal conditions.

Correct Answer is {"dropdown-group-1":"A","dropdown-group-2":"C"}
Explanation
The client is at risk for decreased absorption due to medication interactions.
Rationale
Esomeprazole works by reducing the production of stomach acid, thereby raising the pH level in the stomach. Levothyroxine, like many other medications, is absorbed primarily in the upper part of the small intestine where a more acidic environment is optimal for absorption. When stomach acid production is reduced by esomeprazole, the pH of the stomach increases, which can decrease the dissolution and absorption of levothyroxine.
Correct Answer is C
Explanation
C. When in doubt or when there is ambiguity in the prescription, contacting the provider is essential to clarify the intended dose, timing, and indication for diphenhydramine. "NOW" could mean different things depending on the clinical context. It might imply an urgent need for treatment or administration within a specific timeframe. Contacting the provider allows the nurse to confirm the correct interpretation and ensure the medication is administered safely and appropriately.
A. While this action may seem appropriate, simply notifying the pharmacy does not guarantee that the medication will be available for immediate administration. Additionally, the nurse must ensure that the prescription is clear and appropriate before proceeding with administration.
B. This option implies informing the client that a prescription is available if they choose to use it. This response does not address the immediate need for clarification of the prescription or ensure timely administration as indicated by "NOW."
D. This option suggests a timeframe for administration that may not align with the urgency implied by "NOW." "NOW" typically signifies an immediate need for the medication, and waiting up to 90 minutes
may not be appropriate depending on the clinical situation. Immediate clarification with the provider is necessary to determine the correct timing and urgency of administration.
