Give Dobutamine 5.5 mcg/kg/min. The drug is available as 750 mg in 500 ml of fluid. The client weighs 220 pounds. Calculate mcg/min, mcg/hr, and ml/hr. (Include the unit of measure for each answer).
The Correct Answer is ["22"]
Dobutamine infusion calculation:
- Client weight: 220 pounds
- Dobutamine dose ordered: 5.5 mcg/kg/min
- Dobutamine concentration: 750 mg in 500 mL
- Conversion factor: 1 mg = 1000 mcg
- 1 kg = 2.2 pounds
Calculations:
- Convert client weight to kg: 220 lbs / 2.2 lbs/kg = 100 kg
- Calculate mcg/min: 5.5 mcg/kg/min × 100 kg = 550 mcg/min
- Calculate mcg/hr: 550 mcg/min × 60 min/hr = 33000 mcg/hr
- Calculate mL/hr: Dobutamine concentration is 750 mg/500 mL, which equals 1500 mcg/mL.
- mL/hr = 33000 mcg/hr / 1500 mcg/mL = 22 mL/hr
Answers:
- mcg/min: 550 mcg/min
- mcg/hr: 33000 mcg/hr
- mL/hr: 22 mL/hr

Correct Answer is B
Explanation
A. "You have had a gastrointestinal bleed.": While this can cause fatigue due to anemia, it's not directly related to sickle cell anemia.
B. "You have fewer red blood cells." Sickle cell anemia causes chronic hemolysis, leading to anemia and fatigue. The characteristic sickle-shaped cells are less flexible and prone to hemolysis, resulting in fewer functional red blood cells and reduced oxygen-carrying capacity.
C. "You have an autoimmune disease.": Sickle cell anemia is not an autoimmune disorder.
D. "You have a low ferritin level.": Ferritin levels may be affected, but the primary cause of fatigue in sickle cell anemia is anemia itself, not low ferritin.
Correct Answer is A
Explanation
A. Lethality of the method and availability of means. Assessing the method and means helps determine the immediacy and seriousness of the threat. Knowing the lethality of the method and whether the means are readily available informs the level of intervention needed to keep the client safe.
B. Client's educational and economic background: While socioeconomic factors can influence mental health, they are not immediate priorities in a suicidal crisis.
C. Client's insight into the reasons for the decision: Insight is important for understanding motivations but is secondary to immediate safety concerns.
D. Quality of the client's social support: Social support is crucial but is secondary to assessing imminent risk of harm.
