“Your head will be elevated as high as possible while the catheter is inserted."
"You will be under general anesthesia for this procedure.”
The Correct Answer is B

Correct Answer is D
Explanation
A. The client lifts the walker as it is moved forward: Correct technique to reposition the walker safely.
B. The client advances the walker and takes a step toward it: The walker should be moved first, then the client steps into it for balance.
C. The client grasps the walker by the hand grips on the upper bars: Correct hand placement to maintain control and safety.
D. The client takes multiple steps while holding the walker: The client should move the walker forward and advance one step at a time with the affected leg first, followed by the unaffected leg. Taking multiple steps increases fall risk and reduces stability.
Correct Answer is D
Explanation
A. Lactated Ringer’s contains sodium and electrolytes similar to plasma; it is isotonic and not suitable for correcting hypernatremia, as it won’t lower sodium concentration.
B. 0.9% sodium chloride (normal saline) is isotonic and may worsen hypernatremia by maintaining or increasing sodium levels.
C. 3% sodium chloride is hypertonic and used to treat hyponatremia, not hypernatremia. Administering this would dangerously increase sodium levels.
D. 0.45% sodium chloride (half-normal saline) is hypotonic and helps move water into cells, diluting extracellular sodium and safely lowering serum sodium concentration.
