A nurse is preparing to administer magnesium hydroxide 2.4 g PO daily. Available is magnesium hydroxide suspension 400 mg/5 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 ["30 "]
Given:
- Desired dose of magnesium hydroxide: 2.4 g
- Available strength of magnesium hydroxide suspension: 400 mg/5 mL
First, let's convert the desired dose from grams to milligrams:
2.4 g = 2400 mg
Now, let's find out how many milliliters of magnesium hydroxide suspension correspond to the desired dose:
Volume (mL) = Desired dose / Concentration
Volume (mL) = 2400 mg / 400 mg/5 mL Volume (mL) = (2400 mg * 5 mL) / 400 mg Volume (mL) = 30 mL
So, the nurse should administer 30 mL of magnesium hydroxide suspension.

Correct Answer is ["3.4 "]
Explanation
Given:
- Desired dose of morphine: 0.3 mg/kg
- Client's weight: 99 lb
- Available strength of morphine oral solution: 4 mg/mL
First convert the client's weight from pounds to kilograms: 99 lb ÷ 2.20462 = 44.91 kg (rounded to the nearest hundredth)
The desired dose of morphine:
Desired dose = Client's weight × Dose per kg Desired dose = 44.91 kg × 0.3 mg/kg
Desired dose ≈ 13.473 mg
The milliliters of morphine oral solution this corresponds to:
Volume (mL) = Desired dose / Concentration Volume (mL) = 13.473 mg / 4 mg/mL Volume (mL) ≈ 3.37 mL
So, the nurse should administer approximately 3.4 mL of morphine oral solution.
Correct Answer is B
Explanation
A. Over-the-counter oral preparations can be taken with this medication. - This statement is not relevant to the prescription instructions provided.
B. Choose the same day of each week to take this medication. - Correct. Alendronate is typically taken once a week, so it's important for the client to choose a consistent day each week to take the medication.
C. The client can return to bed after taking the medication, but before eating. - The client should remain upright for 30 minutes after taking alendronate to prevent esophageal irritation.
D. Take the medication at 1800, 30 min after the evening meal. - The prescription specifies to take the medication upon waking, not in the evening.
