A nurse is evaluating a client's response after initiating an intermittent IV bolus of vancomycin. Which of the following findings indicates the client is experiencing an allergic reaction to the medication?
Hypertension
Dyspnea
Tetany
Headache
The Correct Answer is B
A. Hypertension: An allergic reaction to vancomycin typically does not cause high blood pressure. Blood pressure changes may occur with severe reactions, but hypertension is not a primary indicator.
B. Dyspnea: Difficulty breathing indicates a hypersensitivity or allergic reaction to vancomycin. Respiratory distress, along with potential hypotension, rash, or urticaria, signals the need for immediate intervention.
C. Tetany: Tetany is related to hypocalcemia or electrolyte imbalances, not vancomycin allergy. It is not an expected manifestation of an allergic response.
D. Headache: Headache is a nonspecific symptom and is not characteristic of an allergic reaction to vancomycin. It does not reliably indicate hypersensitivity.

Correct Answer is D
Explanation
A. Liver toxicity: Prednisone is metabolized by the liver but is not commonly associated with hepatotoxicity. Liver function monitoring is not a primary concern for long-term prednisone therapy.
B. Hemolytic anemia: Prednisone does not typically cause hemolytic anemia. Its primary hematologic effects involve immunosuppression rather than direct destruction of red blood cells.
C. Hypoglycemia: Prednisone can increase blood glucose levels by promoting gluconeogenesis and reducing peripheral glucose uptake, which may lead to hyperglycemia rather than hypoglycemia.
D. Bone loss: Long-term use of prednisone decreases calcium absorption and bone formation, increasing the risk of osteoporosis and fractures. Monitoring bone density and implementing preventive measures is essential for clients on chronic corticosteroid therapy.
Correct Answer is ["1.3"]
Explanation
Calculation:
- Determine the available concentration of the reconstituted solution in mg/mL.
Vial content: 125 mg
Reconstitution volume: 2 mL
Available concentration (mg/mL) = 125 mg / 2 mL
= 62.5 mg/mL.
- Calculate the volume to administer in milliliters (mL).
Desired dose: 80 mg
Available concentration: 62.5 mg/mL
Volume (mL) = Desired dose (mg) / Available concentration (mg/mL)
= 80 mg / 62.5 mg/mL
= 1.28 mL.
- Round the answer to the nearest tenth.
= 1.3 mL.
