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.)
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 B
Explanation
A) Incorrect- Hip arthroplasty is a scheduled procedure, and there is no immediate indication of a critical condition that requires urgent attention.
B) Correct- Postoperative hemorrhage is a serious complication, and an older client receiving packed red blood cells may be experiencing active bleeding. This situation requires immediate assessment and intervention.
C) Incorrect- While continuous bladder irrigation requires monitoring, it is not as urgent as a potential postoperative hemorrhage.
D) Incorrect- Pain management is important, but it is not as urgent as assessing a client who may be experiencing active bleeding.
Correct Answer is D
Explanation
A) Incorrect- Reviewing transcutaneous bilirubin levels is unrelated to the presence of an enlarged clitoris. Bilirubin levels are typically assessed to monitor jaundice in newborns.
B) Incorrect- Observing and palpating breast tissue for enlargement is not relevant to the condition of salt-wasting congenital adrenal hyperplasia. Breast tissue enlargement would not be associated with this hormonal disorder.
C) Incorrect- Assessing for signs of fluid retention and bilateral pedal edema is important for monitoring for other conditions, but it is not relevant to the enlarged clitoris seen in this specific scenario.
D) Correct- Salt-wasting congenital adrenal hyperplasia is a genetic disorder that results in a deficiency of certain enzymes required for cortisol and aldosterone production. This deficiency leads to an overproduction of androgens, which can cause virilization of female external genitalia. The enlarged clitoris is a result of increased androgen levels. Explaining this finding to the mother provides her with accurate information about the condition and its effects on the infant's anatomy.
