Correct Answer is B

Explanation

A. Hypertension is not a typical finding of hypocalcemia. Instead, hypocalcemia can cause hypotension due to decreased myocardial contractility.
B. Muscle twitching is a common manifestation of hypocalcemia. Low calcium levels increase neuromuscular excitability, leading to twitching, tetany, and spasms.
C. A bounding pulse is not associated with hypocalcemia. Instead, hypocalcemia can cause weak, thready pulses due to decreased cardiac output.
D. Increased urine output is not a direct symptom of hypocalcemia. However, hypercalcemia can lead to polyuria due to its effect on the kidneys.

A. Choose the client's dominant arm for IV access whenever possible. B. Select a site proximal to previous venipuncture sites. C. Initiate IV access on the palmar side of the client's wrist. D. Insert a larger gauge IV catheter to prevent phlebitis.

Correct Answer is B

Explanation

A. Choose the client's dominant arm for IV access whenever possible. The nondominant arm is preferred to minimize interference with daily activities.
B. Select a site proximal to previous venipuncture sites. This is the appropriate action because using a site above a previous one ensures better vein integrity and reduces complications.
C. Initiate IV access on the palmar side of the client's wrist. This site should be avoided as it is more painful and increases the risk of nerve damage.
D. Insert a larger gauge IV catheter to prevent phlebitis. A smaller gauge catheter is preferred when possible, as larger catheters can increase the risk of vein irritation and phlebitis.
