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
A.Taping the tube to the child's cheek is not a recommended practice. It can cause skin irritation, discomfort, or even accidental removal of the tube. Proper securing of the tube to the abdomen using appropriate devices is the preferred method to prevent dislodgement.
B.Applying lubricant to the site is not necessary or recommended. The gastrostomy tube should be kept clean and dry. If any secretions or debris are present, they should be gently cleaned with mild soap and water, followed by thorough rinsing and drying.
C.Some gastrostomy tubes require an extension set for feeding, especially low-profile devices (e.g., button-type gastrostomy tubes). This extension makes it easier to administer feeds or medications and can be removed afterward. However, this is not typically part of routine site care.
D.Securing the tubing to the child's abdomen helps prevent accidental dislodgement or pulling of the gastrostomy tube. This can be done using appropriate securing devices, such as adhesive dressings or commercially available tube holders, as recommended by the healthcare provider.
Correct Answer is A
Explanation
Choice A rationale:
Distributive justice refers to the fair distribution of resources, benefits, and burdens in society. Ensuring that a homeless client receives preventive medical care exemplifies distributive justice as it promotes equal access to healthcare resources for all individuals, regardless of their housing situation.
Choice B rationale:
Being honest with the parents of a child about the need to report suspected abuse is an example of veracity, which is the duty to tell the truth. While honesty is important, it does not directly relate to distributive justice.
Choice C rationale:
Accepting the decision of an older adult client to live alone in her home respects the client's autonomy and independence but does not specifically demonstrate distributive justice.
Choice D rationale:
Keeping a promise to visit with a housebound client is an example of fidelity, the duty to fulfill promises. While it is ethically important, it does not exemplify distributive justice, which pertains to fair resource allocation.
