A nurse is preparing to administer lorazepam 50 mcg/kg IM to a client who weighs 176 lb. Available is lorazepam 4 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["1"]
This is a question that tests the nurse's ability to calculate drug dosages based on the client's weight and the drug concentration. To solve this problem, the nurse needs to follow these steps:
1. Convert the client's weight from pounds to kilograms by dividing by 2.2. 176 lb / 2.2 = 80 kg.
2. Multiply the client's weight in kilograms by the prescribed dose in micrograms per kilogram to get the total dose in micrograms. 80 kg x 50 mcg/kg = 4000 mcg.
3. Convert the total dose in micrograms to milligrams by dividing by 1000. 4000 mcg / 1000 = 4 mg.
4. Divide the total dose in milligrams by the drug concentration in milligrams per milliliter to get the volume in milliliters. 4 mg / 4 mg/mL = 1 mL.
5. Round the answer to the nearest whole number and add a leading zero if it applies. Do not use a trailing zero. The final answer is 1 mL.
Therefore, the nurse should administer 1 mL of lorazepam IM to the client.

Correct Answer is ["2"]
Explanation
To calculate the dosage of diazepam, the nurse needs to use the formula D/H x Q, where D is the desired dose, H is the dose on hand, and Q is the quantity.
In this case, D is 10 mg, H is 5 mg/mL, and Q is 1 mL.
Plugging these values into the formula, we get:
10 mg / 5 mg/mL x 1 mL = 2 mL
Therefore, the nurse should administer 2 mL of diazepam injection to the client.
Correct Answer is B
Explanation
A. Over-the-counter oral preparations can be taken with this medication.
This statement is not accurate. Alendronate should be taken on an empty stomach, 30 minutes before any other oral medications, food, or drinks (except water).
B. Choose the same day of each week to take this medication.
This is the correct interpretation. Taking alendronate on the same day each week helps establish a routine and ensures consistent administration.
C. Take the medication at 1800, 30 min after the evening meal.
This is not correct. Alendronate should be taken in the morning, upon waking, with a full glass of water, and should be followed by 30 minutes of remaining upright.
D. The client can return to bed after taking the medication, but before eating.
This is not correct. After taking alendronate, the client should remain upright for at least 30 minutes to prevent esophageal irritation and optimize absorption. Returning to bed before eating is not recommended.
