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.

Explanation
The correct answer isa. Place a bedside commode next to bed.,b. Measure neurological vital signs every 4 hours.,d. Encourage family to participate in the client’s care.
Choice A rationale:
Placing a bedside commode next to the bed helps prevent falls and promotes independence in toileting, which is crucial for stroke patients who may have mobility issues.
Choice B rationale:
Measuring neurological vital signs every 4 hours is essential to monitor for any changes in the patient’s condition, which can help in early detection of complications.
Choice C rationale:
Suctioning the oral cavity every 4 hours is not typically necessary unless the patient has specific issues with swallowing or secretion management.Routine suctioning can also cause discomfort and potential injury.
Choice D rationale:
Encouraging family to participate in the client’s care provides emotional support and helps in the rehabilitation process.Family involvement can improve the patient’s motivation and adherence to the rehabilitation plan.
Choice E rationale:
Playing classical music in the room can be soothing and beneficial for some patients, but it is not a standard intervention for stroke rehabilitation.The effectiveness of music therapy can vary based on individual preferences.
Correct Answer is ["40"]
Explanation
To determine the amount of mL the child should receive per day, we need to calculate the total daily dose of ampicillin based on the prescription.
The prescription is for 500 mg of ampicillin four times a day, so the total daily dose is: 500 mg × 4 times = 2000 mg/day
The concentration of the suspension is 250 mg/5 mL, which means that there are 250 mg of ampicillin in every 5 mL.
To find out how many mL the child should receive per day, we divide the total daily dose by the concentration:
2000 mg ÷ 250 mg/5 mL = 40 mL/day
Therefore, the child should receive 40 mL of the ampicillin suspension per day.
