A nurse is preparing to administer Ringer lactate 500 mL intravenous (IV) bolus to infuse over 3 hours. The drop factor of the manual IV tubing is 2 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 ["56"]

To calculate the infusion rate, we'll use the following formula:

Infusion rate (gtt/min) = (Volume to be infused (mL) / Time (min)) Drop factor (gtt/mL)

First, calculate the total time in minutes:

3 hours 60 minutes/hour = 180 minutes

Then, calculate the volume per minute:

500 mL / 180 minutes = 2.78 mL/min

Finally, multiply the volume per minute by the drop factor:

2.78 mL/min 20 gtt/mL = 55.6 gtt/min

Therefore, the nurse should set the manual IV infusion to deliver 56 gtt/min.

Correct Answer is ["675"]

Explanation

To calculate the appropriate dose of vancomycin, follow these steps:

Convert pounds to kilograms:
- 198 lb (1 kg / 2.2 lb) = 90 kg
Calculate the total daily dose:
- 15 mg/kg/day 90 kg = 1350 mg/day
Determine the dose per administration:
- 1350 mg/day / 2 doses/day = 675 mg/dose

A. A 28-year-old client who has a history of pelvic inflammatory disease B. A 26-year-old client who is mobile post appendectomy C. A 38-year-old client who reports smoking one pack of cigarettes every day D. A 32-year-old client who has fibrocystic breast disease

Correct Answer is C

Explanation

A. A 28-year-old client who has a history of pelvic inflammatory disease: This is incorrect. While a history of pelvic inflammatory disease does not necessarily contraindicate oral contraceptive use, it should be assessed for any other potential complications or contraindications.
B. A 26-year-old client who is mobile post appendectomy: This is incorrect. Recent surgery, such as an appendectomy, is not a contraindication for oral contraceptives, provided the client is otherwise healthy.
C. A 38-year-old client who reports smoking one pack of cigarettes every day: This is correct. Smoking, especially in women over 35, is a contraindication for oral contraceptives due to the increased risk of cardiovascular events such as thrombosis.
D. A 32-year-old client who has fibrocystic breast disease: This is incorrect. Fibrocystic breast disease does not contraindicate the use of oral contraceptives.
