Question 1 of 5

A nurse is preparing to administer Lactated Ringer's solution IV to infuse at 120 mL/hr for a client who has a respiratory disorder. The drop factor in the manual IV tubing is 60 gtt/mL. The nurse should set the flow rate to deliver how many gtts/min?

Correct Answer: C

Rationale: Using the formula (Volume × Drop factor) ÷ Time = (120 mL × 60 gtt/mL) ÷ 60 min = 120 gtt/min.

Question 2 of 5

A nurse is caring for a client who has hypertension and is to start taking Atenolol. The nurse should instruct the client to monitor which of the following findings is an adverse effect of this medication.

Correct Answer: B

Rationale: Atenolol, a beta-blocker, can cause postural hypotension due to its effect on blood pressure regulation.

Question 3 of 5

A nurse is preparing to administer 400 mL of 0.9% sodium chloride IV over 8 hours. The drop factor of the manual IV tubing is 60 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.).

Correct Answer: A

Rationale: Calculate: (400 mL ÷ 480 min) × 60 gtt/mL = 50 gtt/min.

Question 4 of 5

A nurse is caring for a client who has a prescription for digoxin 0.25 mg PO daily. The amount available is digoxin 0.125 mg tablet. How many tablets should the nurse administer per dose? (Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.).

Correct Answer: B

Rationale: Divide the prescribed dose (0.25 mg) by the tablet strength (0.125 mg): 0.25 mg ÷ 0.125 mg/tablet = 2 tablets.

Question 5 of 5

A nurse is preparing to administer dextrose 3.5% in water (D3.5W) 1200 mL to infuse over 24 hours. The drop factor of the manual IV infusion is 15 gtt/mL. How many gtt/min should the nurse set the infusion to deliver? (Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.).

Correct Answer: B

Rationale: Calculate: (1200 mL ÷ 1440 min) × 15 gtt/mL = 12.495 ≈ 13 gtt/min.
