A client who weighs 65 kg receives a prescription for lorazepam 44 mcg/kg intravenously to be administered 20 minutes before a scheduled procedure. The medication is available in 2 mg/mL vial. How many mL should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["1.4"]
Calculate the total dosage required: 44 mcg/kg * 65 kg = 2860 mcg. Convert mcg to mg: 2860 mcg ÷ 1000 = 2.86 mg.
Divide by concentration: 2.86 mg ÷ 2 mg/mL = 1.43 mL.
Considering the vial contains 2 mg/mL, the nurse should administer around 1.43 mL, which can be rounded to 1.4 mL.

Correct Answer is ["A","C","D"]
Explanation
A) Correct- This is correct advice. Juice is not recommended for infants due to its high sugar content and lack of essential nutrients. It can contribute to excessive calorie intake and dental caries.
B) Incorrect- This is not accurate for a 9-month-old infant. By 9 months, most infants have already started to transition to solid foods, and their primary source of nutrition should be from a variety of solid foods, not formula.
C) Correct- This is correct advice. By 9 months, infants can begin to consume a variety of complementary foods to meet their nutritional needs. Adding raw fruit, cheese, or cooked vegetables can provide important nutrients and help introduce different tastes and textures.
D) Correct- As infants transition to solid foods, they typically require more frequent meals and snacks to meet their energy and nutrient needs. Breast milk or formula intake may also gradually decrease as solid foods are introduced.
E) Incorrect- Fluoride supplementation may be considered based on the fluoride content of the water supply and the child's risk of dental caries. However, this advice is not specific to the child's nutrition and feeding progression.
F. Incorrect- At 9 months, infants should not transition to whole cow's milk as their main source of nutrition. Breast milk or infant formula remains the primary source of nutrition, and cow's milk can be introduced as a beverage and ingredient in cooking after the first year of life.
Correct Answer is A
Explanation
A) Correct- this can help them structure their time, reduce boredom and anxiety, and increase their sense of control and achievement. This can also foster social interaction and engagement with the staff and peers. A schedule of planned daily activities is consistent with the principles of psychosocial rehabilitation, which is an evidence-based approach for people with schizophrenia.
B) Incorrect- this may be too challenging or stressful for the client, especially if they have cognitive impairments or negative symptoms.
C) Incorrect- may expose them to unfamiliar or unpredictable situations that could trigger or worsen their psychotic symptoms.
D) Incorrect- it is not an intervention that directly addresses the client's current problem of social isolation.
