Question 1 of 5

A nurse is preparing to administer dextrose 5% in water (DW) 150 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.)

Correct Answer: A

Rationale:
To calculate: 150 mL × 10 gtt/mL ÷ 180 min = 8.33 gtt/min, rounded to 8 gtt/min, ensuring accurate infusion rate.

Question 2 of 5

A nurse is caring for a client who is taking digoxin for heart failure and develops indications of severe digoxin toxicity. Which of the following medications should the nurse prepare to administer?

Correct Answer: D

Rationale: Fab antibody fragments (Digibind or DigiFab) bind to digoxin, neutralizing its effects and treating severe toxicity, which can cause life-threatening arrhythmias.

Question 3 of 5

A nurse is assessing a client who is receiving continuous IV therapy through a peripheral IV. The catheter site is cool and taut, and there is IV fluid leaking. The nurse should identify that the client has manifestations of which of the following complications?

Correct Answer: D

Rationale: Cool, taut skin and fluid leakage indicate infiltration, where IV fluid escapes into surrounding tissue due to improper catheter placement.

Question 4 of 5

A nurse is assessing an older adult client who is receiving IV therapy. The nurse should recognize that which of the following findings indicates fluid volume excess? (Select all that apply.)

Correct Answer: A,C,E

Rationale: Bounding pulse, pitting edema, and crackles indicate fluid volume excess due to increased blood volume, tissue fluid accumulation, and pulmonary congestion.

Question 5 of 5

A nurse is providing discharge teaching to the parent of a child who is prescribed diphenhydramine 25 mg elixir every 4 hr as needed. The amount available is diphenhydramine elixir 12.5 mg/5 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Correct Answer: A

Rationale:
To calculate: 25 mg ÷ (12.5 mg/5 mL) = 10 mL, ensuring the correct dose of diphenhydramine is administered.
