The healthcare provider prescribes dopamine 2 mcg/kg/min intravenously (IV) for client who weighs 60 kg. The IV bag contains dopamine 200 mg in dextrose 5% in water (DW) 250 mL. The nurse should program the infusion pump to deliver how many mL/hour? (Enter numerical value only.)

Answer and Explanation

The Correct Answer is ["9"]

Here are the steps you can follow to calculate the infusion pump flow rate:

Step 1: Calculate the prescribed dose in mcg/min

Dose per weight: 2 mcg/kg/min * 60 kg = 120 mcg/min

Step 2: Convert the concentration in the IV bag to mcg/mL

Convert mg to mcg: 200 mg * 1000 mcg/mg = 200,000 mcg
Concentration: 200,000 mcg / 250 mL = 800 mcg/mL

Step 3: Calculate the flow rate in mL/min

Flow rate: 120 mcg/min / 800 mcg/mL = 0.15 mL/min

Step 4: Convert the flow rate to mL/hour

Hour conversion: 0.15 mL/min * 60 min/hour = 9 mL/hour

Therefore, the nurse should program the infusion pump to deliver 9 mL/hour.

Correct Answer is C

Explanation

A) Incorrect- This position is not ideal for managing a nosebleed because it does not promote drainage and may lead to blood flowing down the throat.
B) Incorrect- Leaning the head backward can cause blood to flow down the throat and may lead to choking or aspiration.
C) Correct- Placing the child in a sitting position and leaning forward helps prevent blood from flowing down the back of the throat, which can lead to choking or aspiration. Leaning forward allows the blood to drain out through the nostrils.
D) Incorrect- Placing the child in a supine position with raised legs is not recommended for managing a nosebleed, as it may lead to blood flowing down the throat.

A. Misplacing car keys. B. Difficulty performing familiar tasks. C. Losing sense of time. D. Problems with performing basic calculations. E. Becoming lost in a usually familiar environment.

Choice A rationale: Misplacing car keys occasionally is a common occurrence and may not necessarily indicate Alzheimer's disease. It can happen to anyone, especially when distracted or in a hurry.

Choice B rationale: Difficulty performing familiar tasks, such as cooking a meal or driving to a familiar location, is an early warning sign of Alzheimer's disease. It indicates changes in cognitive function.

Choice C rationale: Losing sense of time, such as not knowing the date, day of the week, or season, can be an early indicator of Alzheimer's disease. It reflects impairments in temporal orientation.

Choice D rationale: Problems with performing basic calculations, such as managing finances or following a recipe, are early signs of Alzheimer's disease. It shows a decline in cognitive abilities related to numbers and problem-solving.

Choice E rationale: Becoming lost in a usually familiar environment, such as getting disoriented in one's own neighborhood, is a significant early warning sign of Alzheimer's disease. It suggests spatial and memory impairments.
