The nurse reviews new laboratory results for assigned clients. Which finding is the priority for the nurse to report to the supervising registered nurse?
- A. CD4+ cell count of 600 cells/uL in a client with HIV and oral candidiasis who is receiving PO fluconazole
- B. Hemoglobin A1c of 7.3% in a client with type 2 diabetes and pneumonia who is receiving IV levofloxacin heparin infusion
- C. Serum glucose of 65 mg/dL (3.61 mmol/L) in a client with radiation enteritis who is receiving total parenteral nutrition
Correct Answer: C
Rationale: A serum glucose of 65 mg/dL indicates hypoglycemia, which is critical in a client on total parenteral nutrition, as it may require immediate adjustment of glucose infusion or administration of dextrose.

A client is receiving nitroprusside IV for the treatment of acute heart failure with pulmonary edema. What diagnostic lab value should the nurse monitor when a client is receiving this medication?
- A. Potassium level
- B. Arterial blood gasses
- C. Blood urea nitrogen
- D. Thiocyanate
Correct Answer: D

The client has just returned from having a cast placed on the right forearm and is found putting a lead pencil in the cast to 'reach the itch.' What is the nurse's priority action?
- A. Offer the client a straw to reach the itch instead of a lead pencil
