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.)
4 mL/hr.
5 mL/hr.
6 mL/hr.
7 mL/hr.
The Correct Answer is C
Step 1: Convert the dopamine hydrochloride dose from mcg to mg. We know that 1 mg = 1000 mcg. So, 4 mcg = 0.004 mg.
Step 2: Calculate the total amount of dopamine hydrochloride the client needs per minute. We know that the client weighs 80 kg and the dose is 0.004 mg/kg/min. So, 0.004 mg/kg/min × 80 kg = 0.32 mg/min.
Step 3: Convert the total amount of dopamine hydrochloride the client needs per minute to an hourly rate. We know that 1 hour = 60 minutes. So, 0.32 mg/min × 60 min/hr = 19.2 mg/hr.
Step 4: Calculate the volume of the solution that contains 19.2 mg of dopamine hydrochloride. We know that the solution contains 800 mg in 250 mL. So, (19.2 mg ÷ 800 mg) × 250 mL = 6 mL.
Therefore, the nurse should set the IV infusion to deliver 6 mL/hr (rounded to the nearest whole number).

Correct Answer is D
Explanation
The correct answer is Choice D.
Choice A rationale: Acupuncture is typically administered by a trained acupuncturist, not by the nurse. It is not commonly initiated upon arrival at the labor unit.
Choice B rationale: Biofeedback is a technique that usually requires prior training and practice; it is not typically taught for the first time at the beginning of labor.
Choice C rationale: Transcutaneous electrical nerve stimulation (TENS) can help manage back pain during labor but is not specifically used for pelvic pressure.
Choice D rationale: Using an ultrasound picture as a focal point during contractions is a common nonpharmacological pain management technique. Focal points help the client concentrate and manage pain through visualization and distraction.
Correct Answer is C
Explanation
Choice A rationale:
Expressing concern about another shift's holiday hours does not necessarily involve interpersonal conflict. It may reflect dissatisfaction but doesn't involve direct conflict between individuals.
Choice B rationale:
A personal difficulty with caring for clients who have HIV could be a challenge for the nurse, but it's not an example of interpersonal conflict. It represents a personal struggle rather than a conflict with another individual.
Choice C rationale:
Insulting comments directed at a nurse by another nurse represent interpersonal conflict. Such behavior involves a direct clash of personalities and can create a hostile work environment, affecting the nurse's well-being and job performance. Addressing this type of conflict is crucial for maintaining a positive work atmosphere.
Choice D rationale:
Submitting a complaint about another department's handoff reporting might indicate dissatisfaction or concerns about workflow, but it's not necessarily an interpersonal conflict. It could be a communication issue or a difference in professional opinion rather than a direct clash between individuals.
