A nurse has received an order to administer Morphine 5mg IV once immediately.
The available concentration is 2.5 mg/mL. How many mL of morphine should the nurse prepare for administration?
0.5 mL
1 mL
2 mL
4 mL
The Correct Answer is C
Step 1: The order is to administer Morphine 5mg IV once immediately. The available concentration is 2.5 mg/mL. To find out how many mL of morphine the nurse should prepare for administration, we need to divide the ordered dose by the available concentration.
Step 2: Calculation: 5 mg ÷ 2.5 mg/mL = 2 mL So, the nurse should prepare 2 mL of morphine for administration.

Correct Answer is D
Explanation
Choice D rationale
Changes in the cervix, including effacement (thinning) and dilation (opening), are reliable signs of true labor. During true labor, contractions cause the cervix to thin and open to prepare for the passage of the baby. This is in contrast to Braxton Hicks contractions, or “false labor,” which are irregular and do not result in changes to the cervix.
Choice A rationale
The position of the presenting part can provide information about the progress of labor and the likely need for interventions, but it is not a definitive sign of labor.
Choice B rationale
Membrane rupture, or “water breaking,” can occur before or during labor. However, not all women experience a noticeable rupture of membranes, and sometimes the fluid can leak slowly, making it less noticeable.
Choice C rationale
A regular contraction pattern can be a sign of labor, but contractions can also occur in patterns during false labor. Therefore, contraction pattern alone is not a definitive sign of labor.
