A nurse is assessing a client who has a new diagnosis of diabetes mellitus. The nurse should identify that which of the following findings is a manifestation of hyperglycemia?

Rationale:
A. Administer vasopressin to the client: Vasopressin is used to constrict splanchnic circulation and reduce portal pressure, helping control variceal bleeding. However, medication administration requires functional IV access, which must be verified or established before proceeding.

B. Request blood from the blood bank: Blood transfusion is necessary to treat hemorrhagic shock and restore circulating volume, but requesting blood is not the immediate priority before ensuring access for administration.

C. Verify that the client has adequate IV access: Establishing or verifying large-bore IV access is the first priority in any client experiencing hemorrhagic shock. This enables the rapid infusion of fluids, blood products, and medications necessary to stabilize the client.

D. Insert an indwelling urinary catheter: Monitoring urine output is important for assessing renal perfusion and fluid status, but it is not the most urgent intervention when the client is actively bleeding and hemodynamically unstable.

Rationale:

A. The nurse provides wound care to a client at the time promised to the client: Providing care as scheduled reflects reliability and professionalism, but it does not involve speaking up for or securing specific services in the client's best interest, which defines advocacy.

B. The nurse refers a client who has chronic obstructive pulmonary disease for palliative care services: This demonstrates advocacy by ensuring the client has access to specialized care that supports comfort, dignity, and symptom management—especially important in progressive, life-limiting illness.

C. The nurse declines to inform a client's neighbor about the client's prognosis: This action protects client confidentiality and privacy, which is ethically correct, but it does not represent active support or promotion of the client's needs or preferences.

D. The nurse files an incident report regarding a medication error: Filing an incident report supports patient safety and institutional accountability. However, it does not reflect direct advocacy, as it does not involve pursuing specific care or services for the client.
