A nurse is assisting with care of a client who has a prescription for 3,000 mL of intravenous fluids over the next 24 hr. The nurse should set the IV pump to deliver how many mL/hr? (Round to the nearest whole number)

Answer and Explanation

The Correct Answer is ["125"]

To calculate the rate at which the IV pump should be set to deliver 3,000 mL of intravenous fluids over 24 hours, you would divide the total volume (3,000 mL) by the total time (24 hours):

Rate (mL/hr) = Total volume (mL) / Total time (hours)

Rate = 3,000 mL / 24 hours

Rate ≈ 125 mL/hr

Rounding to the nearest whole number, the IV pump should be set to deliver approximately 125 mL/hr.

Correct Answer is ["50"]

Explanation

To calculate the infusion rate in gtt/min, the nurse needs to use the formula:

Infusion rate (gtt/min) = Volume (mL) x Drop factor (gtt/mL) / Time (min)

Plugging in the given values, we get:

Infusion rate (gtt/min) = 400 mL x 60 gtt/mL / 480 min

Simplifying, we get:

Infusion rate (gtt/min) = 50 gtt/min

Therefore, the nurse should set the manual IV infusion to deliver 50 gtt/min.

A. Bacteriostatics are narrow spectrum drugs and bactericidal drugs are broad spectrum B. Bacteriostatic drugs inhibit bacterial growth, and bactericidal drugs actually kill bacteria C. Bacteriostatics work by inhibiting protein synthesis and bactericidal drugs work by inhibiting nucleic acid synthesis D. Bacteriostatic drugs actually kill bacteria and bactericidal drugs inhibit bacterial growth

Correct Answer is B

Explanation

A. Bacteriostatics are narrow spectrum drugs, and bactericidal drugs are broad spectrum:

This statement is incorrect. The spectrum of activity (narrow vs. broad) of an antibiotic refers to the range of bacterial species that it can target, not whether it is bacteriostatic or bactericidal.

B. Bacteriostatic drugs inhibit bacterial growth, and bactericidal drugs actually kill bacteria:

This statement is correct. Bacteriostatic drugs work by inhibiting the growth and reproduction of bacteria without directly killing them, whereas bactericidal drugs directly kill bacteria.

C. Bacteriostatics work by inhibiting protein synthesis, and bactericidal drugs work by inhibiting nucleic acid synthesis:

This statement is incorrect. Both bacteriostatic and bactericidal drugs can target various bacterial cellular processes, including protein synthesis, nucleic acid synthesis, cell wall synthesis, and others. The mechanism of action is not a definitive factor in distinguishing between bacteriostatic and bactericidal drugs.

D. Bacteriostatic drugs actually kill bacteria, and bactericidal drugs inhibit bacterial growth:

This statement is incorrect. It contradicts the established definitions of bacteriostatic and bactericidal drugs. Bacteriostatic drugs inhibit bacterial growth without killing the bacteria, while bactericidal drugs directly kill bacteria.
