A nurse is preparing to administer dextrose 5% in water 350 mL IV to infuse over 3 hr. The drop factor of the manual IV tubing is 10 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (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 ["19"]

Drip rate (gtt/min) = (Volume to be infused in mL × Drop factor) ÷ Time of infusion in minutes


Given:

Volume to be infused = 350 mL Drop factor = 10 gtt/mL
Time of infusion = 3 hours = 180 minutes


Plugging these values into the formula:


Drip rate = (350 mL × 10 gtt/mL) ÷ 180 min Drip rate ≈ (3500 gtt) ÷ 180 min
Drip rate ≈ 19.4 gtt/min

Rounding to the nearest whole number, the drip rate is approximately 19 gtt/min. Therefore, the nurse should set the manual IV infusion to deliver 19 gtt/min.

  6. without adding more air into NPH vial, carefully withdraw NPH dose



B. Withdraw the regular insulin from the vial: This step should occur after injecting air into the regular insulin vial. The nurse should draw up the regular insulin before drawing up the NPH
insulin.

C. Inject air into the regular insulin vial: Inject air into the regular insulin vial is not thecorrect first step to avoid contamination of the clear insulin with cloudy insulin..
D. Withdraw the NPH insulin from the vial: This step should occur after withdrawing the regular insulin. The nurse should draw up the NPH insulin after drawing up the regular insulin to ensure the correct sequence and dosage.

Correct Answer is B

Explanation

A. Heart rate is important to monitor, but it is not the most immediate indicator of a life-threatening complication from midazolam. Changes in heart rate can occur, but they are usually secondary to respiratory issues.

B. Oxygen saturation is the priority because midazolam, a benzodiazepine, can cause respiratory depression and airway compromise. Monitoring oxygenation allows for rapid detection of hypoxia, which is the most immediate risk during moderate sedation.

C. Level of consciousness should be assessed, as midazolam causes sedation and can lead to oversedation. However, airway and breathing take priority over neurological assessment in this situation.

D. Temperature is not significantly affected by midazolam and is not an immediate concern during moderate sedation. It is therefore the lowest priority among the options provided.
