A nurse is preparing to administer dopamine hydrochloride 4 mcg/kg/min via continuous infusion.

Available is dopamine hydrochloride in a solution of 800 mg in a 250 mL bag.

The client weighs 80 kg. The nurse should set the IV infusion to deliver how many mL/hr? (Round the answer to the nearest whole number.

Use a leading zero if it applies.)

Choice A rationale:

Give the client protamine if signs of magnesium sulfate toxicity occur. Protamine is not the antidote for magnesium sulfate toxicity. Calcium gluconate or calcium chloride is used to counteract the effects of magnesium sulfate toxicity by antagonizing the action of magnesium on the neuromuscular junction and the heart.

Choice B rationale:

Monitor the FHR via Doppler every 30 min. While fetal heart rate (FHR) monitoring is important during magnesium sulfate infusion due to the risk of fetal distress, using Doppler every 30 minutes may not provide continuous and accurate monitoring. Continuous electronic fetal monitoring is the standard of care in this situation.

Choice C rationale:

Restrict the client's total fluid intake to 250 mL/hr. Magnesium sulfate is excreted by the kidneys, so maintaining adequate urine output is crucial to prevent magnesium toxicity. Restricting fluid intake to 250 mL/hr would likely reduce urine output, leading to an increased risk of magnesium sulfate accumulation in the body, which could be harmful.

Choice D rationale:

Measure the client's urine output every hour. Monitoring urine output is essential during magnesium sulfate infusion as it helps assess renal function and magnesium excretion. Adequate urine output (at least 30 mL/hr) is necessary to prevent magnesium toxicity. Therefore, measuring the client's urine output every hour is a critical nursing intervention to ensure the safety of the client.

Choice A rationale:

(Correct Choice) Checking the expiration date on the safety inspection sticker of the pump is essential to ensure the equipment is functioning properly and safely. Using expired equipment can compromise the client's safety and the effectiveness of the treatment.

Choice B rationale:

Verifying that the extension cord for the pump is ungrounded is important for electrical safety. However, it is not the nurse's responsibility to do this. This action should be performed by a qualified electrician or facility maintenance personnel.

Choice C rationale:

Reporting the pump with a frayed cord is essential. However, it is not safe to proceed with the infusion in this situation. Using damaged equipment can lead to electrical hazards and compromise the client's safety.

Choice D rationale:

Obtaining a surge protector is important for protecting the pump and other electrical appliances from power surges. While this is a good practice, it is not the first action the nurse should take when preparing to initiate intravenous fluids.
