What is the definition of substance misuse?
The use-even one time-of any substance.
The use of a psychoactive compound/drug/substance in an amount or frequency that causes harm to the person or others.
The use of any substance in a manner, situation, amount or frequency that can cause harm to users or to those around them.
The use of a psychoactive compound/drug/substance that poses hazards to health and impacts all aspects of the client's life.
The Correct Answer is B
A. The use-even one time-of any substance: Too broad and does not specify harm or misuse. Using a prescribed medication once wouldn't necessarily be misuse.
B. The use of a psychoactive compound/drug/substance in an amount or frequency that causes harm to the person or others. Defines misuse as harmful use impacting health or safety. Substance misuse involves using substances in a way that causes harm, which can include physical, psychological, or social consequences.
C. The use of any substance in a manner, situation, amount or frequency that can cause harm to users or to those around them: While this choice highlights potential harm, it lacks specificity regarding psychoactive substances. It’s a broader concept that may include non-psychoactive substances as well.
D. The use of a psychoactive compound/drug/substance that poses hazards to health and impacts all aspects of the client's life: This definition is comprehensive but not as succinct as choice B. It encompasses physical, psychological, and social consequences of substance misuse.

Correct Answer is C
Explanation
A. "Exposure to sunlight will help to strengthen your eyes.": Sunlight exposure is not recommended as it can exacerbate symptoms.
B. "These are unusual symptoms. I will ask the provider for an ophthalmology referral.": These symptoms are characteristic of Graves' ophthalmopathy and do not require an immediate referral unless severe.
C. "Eye drops and dim lighting can improve your symptoms." These interventions can help alleviate discomfort associated with dryness and light sensitivity in hyperthyroidism-related eye changes (Graves' ophthalmopathy). Dim lighting reduces glare, which can be uncomfortable for clients with sensitivity to light. Eye drops can provide lubrication for dry eyes.
D. "Surgery will be necessary to correct the damage to your eyes.": Surgery is considered for severe cases or when other treatments fail, not typically as an initial intervention.
Correct Answer is ["22"]
Explanation
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
