A nurse is preparing to administer 0.9% sodium chloride (NSS) 3000 mL IV to infuse over 24 hr. The drop factor on 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 ["21"]

Total volume in mL: 3000 mL

Time in hours: 24 hours

Total volume to be infused in minutes: We need to convert hours to minutes. There are 60 minutes in 1 hour. Therefore, total time in minutes = 24 hours * 60 minutes/hour = 1440 minutes

Drop factor: 10 gtt/mL

Rate in mL/min: We can divide the total volume (mL) by the total time (minutes) to find the flow rate in mL per minute. Rate (mL/min) = 3000 mL / 1440 minutes = 2.08 mL/min (rounded to two decimal places)

Rate in gtt/min: To find the rate in gtt/min, multiply the rate in mL/min by the drop factor. Rate (gtt/min) = 2.08 mL/min * 10 gtt/mL = 20.8 gtt/min

Rounding the answer to the nearest whole number: 20.8 gtt/min rounds off to the nearest whole number to 21 gtt/min.

Correct Answer is ["200"]

Explanation

To calculate the infusion rate in mL/hr for administering ceftriaxone 1 g via intermittent IV bolus over 30 minutes, you would use the formula: (Total Volume in mL / Time in hours) = Rate in mL/hr. In this case, the total volume of the solution is 100 mL, and the time frame is 0.5 hours (since 30 minutes is half an hour). Therefore, the calculation would be 100 mL / 0.5 hours = 200 mL/hr.

A. Women should have a yearly clinical breast examination starting at age 45. B. Clients should have a colonoscopy at age 40 and every 10 years thereafter. C. Women should start yearly mammograms at age 30. D. Clients should have a yearly test for fecal occult blood.

Correct Answer is D

Explanation

A. Clinical breast examinations are generally recommended every 1 to 3 years for women in their 20s and 30s and annually for women 40 and older. However, the emphasis has shifted towards mammography as a primary screening tool.

B. Routine screening for colorectal cancer typically begins at age 45 for average-risk individuals, not 40. Colonoscopies are generally recommended every 10 years if results are normal.

C. Mammograms are typically recommended to start at age 40 for average-risk women, with yearly screening starting at age 45 or 50 depending on guidelines.

D. Annual testing for fecal occult blood is a recommended screening method for colorectal cancer starting at age 45, as it helps detect blood in the stool which can be an early sign of colorectal cancer.
