A nurse is preparing to administer morphine 15 mg subcutaneously. The amount available is morphine injection 10 mg/mL. How many mL should the nurse administer?
(Round to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["1.5"]

To calculate the amount of morphine injection in mL that the nurse should administer, we can

use the formula:

Volume (mL) = Desired dose (mg) / Concentration (mg/mL)

In this case, the desired dose is 15 mg and the concentration is 10 mg/mL. Plugging these values into the formula, we get:

Volume (mL) = 15 mg / 10 mg/mL = 1.5 mL

Therefore, the nurse should administer 1.5 mL of morphine injection subcutaneously

Correct Answer is A

No explanation

A. 3 cm below the umbilicus B. 5 cm above the umbilicus C. 3 cm above the umbilicus D. At the umbilicus

Correct Answer is D

Explanation

At 22 weeks of gestation, the uterine fundus is typically located at or near the level of the umbilicus. Fundal height generally corresponds to gestational age in centimeters, so at 22 weeks, the fundus is expected to be approximately 22 cm from the pubic symphysis, which aligns with the umbilicus.

A. 3 cm below the umbilicus: This is too low, as the fundus at 22 weeks should be at or slightly above the umbilicus.
B. 5 cm above the umbilicus: This is too high, as the fundus typically reaches this level closer to 24–26 weeks.
C. 3 cm above the umbilicus: This is slightly higher than expected for 22 weeks, though the fundus may be just above the umbilicus in some cases.
D. At the umbilicus: This is the most accurate, as the fundus is typically at the level of the umbilicus at 20–22 weeks.

Final Answer: D. At the umbilicus
