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 ["1.3"]
Explanation
1. Convert the infant's weight from pounds to kilograms. We can use the conversion factor 1 kg
= 2.2 lb. So, 22 lb x (1 kg / 2.2 lb) = 10 kg.
2. Calculate the total daily dose of amoxicillin for the infant. We can use the formula D = d x W, where D is the total daily dose, d is the dose per kg per day, and W is the weight in kg. So, D = 20 mg x 10 kg = 200 mg.
3. Calculate the single dose of amoxicillin for the infant. We can divide the total daily dose by the number of doses per day. Since the prescription is for every 8 hours, there are 3 doses per day. So, 200 mg / 3 = 66.67 mg.
4. Calculate the volume of amoxicillin suspension for the single dose. We can use the ratio of the concentration of the suspension, which is 250 mg per 5 mL. So, 66.67 mg x (5 mL / 250 mg) =
1.33 mL.
5. Round the volume to the nearest tenth= 1.3 mL
Correct Answer is B
Explanation
In this situation, the client has a fingerstick glucose level of 35 mg/dL (1.94 mmol/L) and is alert but diaphoretic. The charge nurse should take the following action:
Give the client a glass of orange juice.
A glucose level of 35 mg/dL (1.94 mmol/L) is considered significantly low (hypoglycemia), and the client's symptoms of diaphoresis indicate that the low glucose level is likely causing the symptoms. Providing the client with a glass of orange juice or another source of fast-acting carbohydrate is appropriate to quickly raise the blood sugar level and alleviate the symptoms of hypoglycemia.
Collecting a blood sample for hemoglobin A1c (HbA1c) is not necessary in this acute situation. HbA1c reflects the average blood glucose level over the past 2-3 months and is used to assess long-term glycemic control in clients with diabetes. It does not provide immediate information or guide immediate interventions for acute hypoglycemia.
Notifying the healthcare provider is not the first action to take in this situation. The client's low glucose level can be promptly addressed by administering a source of fast-acting carbohydrate, such as orange juice. If the client's symptoms persist or worsen despite appropriate intervention, or if there are other concerning factors, then notifying the healthcare provider would be appropriate.
Assessing the client for polyuria (excessive urination) and polyphagia (excessive hunger) is important in the overall management of diabetes, but it is not the immediate action to take in this acute situation of hypoglycemia. The priority at this time is to address the low blood sugar level and relieve the client's symptoms.
