A nurse is caring for client who has sepsis and a prescription for vancomycin 1 g in 250 mL dextrose 5% (D,W) over 2 hr by IV intermittent bolus. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["125"]

To calculate the IV pump rate:

- Total volume of dextrose solution: 250 mL

- Time for infusion: 2 hours

- The pump rate is calculated as total volume divided by time: 250/2

- This results in a pump rate of 125 mL/hr

Therefore, the nurse should set the IV pump to deliver 125 mL/hr.

Correct Answer is C

Explanation

A. The side-lying position is not appropriate for paracentesis because it does not allow optimal access to the abdomen and can make fluid removal more difficult.

B. The supine position is also not suitable for paracentesis, as it may not allow for proper drainage and can increase the risk of respiratory compromise, especially in clients with large volumes of ascitic fluid.

C. High-Fowler’s position is correct because it helps pool the ascitic fluid in the lower abdomen, making it easier to access and drain during the procedure. This position also helps improve breathing by relieving pressure on the diaphragm caused by the ascites.

D. The leaning forward position is not appropriate for paracentesis, as it can be uncomfortable and does not provide optimal access to the abdominal cavity for fluid removal.

A. Lateral segment of the right lower lobe B. Lateral segment of the left lower lobe C. Posterior segment of the right middle lobe D. Posterior segment of the right lower lobe

Correct Answer is A

Explanation

A. Lateral segment of the right lower lobe is the correct answer because placing the client on the left side in Trendelenburg position promotes drainage from the right lower lobe’s lateral segment by using gravity to mobilize secretions.
B. Lateral segment of the left lower lobe would require the client to be positioned on the right side rather than the left.
C. Posterior segment of the right middle lobe would require the client to be positioned in a different way, typically supine with a slight Trendelenburg tilt.
D. Posterior segment of the right lower lobe would require a prone position in Trendelenburg, not left-side lying.
