A nurse is preparing to administer magnesium hydroxide 2 tbsp PO. 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 ["30"]
The nurse should use the following formula to convert tablespoons to milliliters: 1 tbsp = 15 mL.
Therefore, 2 tbsp = 2 x 15 mL = 30 mL.
The nurse should administer 30 mL of magnesium hydroxide PO.

Correct Answer is ["2"]
Explanation
To calculate the number of capsules needed to administer 0.5 g of cefaclor PO, the nurse should use the following formula:
Number of capsules = (Desired dose / Available dose) x 1 capsule
Plugging in the values from the question, we get:
Number of capsules = (0.5 g / 0.25 g) x 1 capsule
Number of capsules = 2 capsules
Therefore, the nurse should plan to administer 2 capsules of cefaclor PO to the client.
Correct Answer is ["1"]
Explanation
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.
