A nurse is caring for a client who is receiving diazepam as conscious sedation for an endoscopy, Which of the following antidotes should the nurse have on hand during the procedure?

Furosemide is a loop diuretic commonly used to treat fluid volume excess by promoting diuresis. One of the expected outcomes of furosemide administration is an increased urinary output as excess fluid is eliminated from the body. Therefore, if the medication has been effective, the nurse would expect to see an increased urinary output as a result of the diuretic effect.

Increased respiratory rate (B) is not an expected outcome of furosemide administration. It may occur in some cases due to increased fluid elimination and potential electrolyte imbalances, but it is not the primary indicator of the medication's effectiveness.

Decreased blood pressure (C) is a possible outcome of furosemide administration due to the diuretic effect and subsequent reduction in fluid volume. However, it is not the most specific indicator of the medication's effectiveness in this case.

Increased pulse (D) is not a typical finding associated with the effectiveness of furosemide. In fact, furosemide can sometimes cause a decrease in heart rate due to its impact on fluid and electrolyte balance.

Exenatide is a medication used to treat type 2 diabetes mellitus. The nurse should plan to administer exenatide via the subcutaneous route.

Subcutaneous administration involves injecting the medication into the fatty tissue just below the skin. Exenatide is available as a subcutaneous injection and is typically given in the abdomen, thigh, or upper arm.

Let's go through the other options:

A. Oral: Exenatide is not available in an oral form. It is a peptide-based medication that would be destroyed by stomach acid and digestive enzymes if taken orally. Therefore, it must be administered via injection to be effective.

B. Intramuscular: Exenatide is not administered intramuscularly. Intramuscular injections are given deep into the muscle tissue, and exenatide is not formulated or intended for this route of administration.

D. Intravenous: Exenatide is not administered intravenously. Intravenous injections are given directly into the bloodstream, and exenatide is not suitable for this route of administration.
