A nurse is preparing to administer morphine 0.2 mg/kg IM to a child who weighs 77 lb. Available is morphine injection 10 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.7"]
To calculate the dosage of morphine for a child, the nurse needs to convert the child's weight from pounds to kilograms and then multiply it by the prescribed dose per kilogram. The nurse also needs to divide the resulting amount by the concentration of the morphine injection to get the volume to be administered. The formula is:
Volume (mL) = (Weight (kg) x Dose (mg/kg)) / Concentration (mg/mL)
In this case, the child weighs 77 lb, which is equivalent to 35 kg (77 / 2.2 = 35). The prescribed dose is 0.2 mg/kg and the concentration of the morphine injection is 10 mg/mL. Therefore, the volume to be administered is:
Volume (mL) = (35 x 0.2) / 10
Volume (mL) = 0.7
The nurse should round the answer to the nearest tenth, which is 0.7 mL.

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.
