A woman in labor who received an opioid for pain relief develops respiratory depression.
The nurse would expect which agent to be administered?.
Butorphanol.
Promethazine.
Fentanyl.
Naloxone.
The Correct Answer is D
Answer and explanation
Choice A rationale:
Butorphanol is an opioid agonist-antagonist. It would not be the first choice to treat opioid-induced respiratory depression because it can also cause respiratory depression.
Choice B rationale:
Promethazine is an antihistamine that has sedative effects and could potentially worsen respiratory depression.
Choice C rationale:
Fentanyl is a potent opioid and would likely exacerbate respiratory depression.
Choice D rationale:
Naloxone is an opioid antagonist used to reverse the effects of opioids such as respiratory depression.

Correct Answer is C
Explanation
Choice A rationale:
Station -2 means the presenting part is 2 cm above the ischial spines. Engagement usually occurs at 0 station.
Choice B rationale:
Station +1 means the presenting part is 1 cm below the ischial spines. This usually occurs during labor, not necessarily at engagement.
Choice C rationale:
Station 0 means the presenting part is at the level of the ischial spines. This is typically when engagement occurs.
Choice D rationale:
Station -1 means the presenting part is 1 cm above the ischial spines. Engagement usually occurs at 0 station.
Correct Answer is ["mLs\/hr."]
Explanation
Answer and explanation
Step 1 is to calculate the total units of Heparin in 1 mL of the solution. This is done by dividing the total units of Heparin in the bag (40,000 units) by the total volume of the bag (500 mL). So, 40,000 units ÷ 500 mL = 80 units/mL. Step 2 is to calculate the rate at which the IV pump should be set. This is done by dividing the ordered amount of Heparin per hour (1600 units) by the units of Heparin per mL (80 units/mL). So, 1600 units/hr ÷ 80 units/mL = 20 mL/hr.
So, the correct answer is 20 mL/hr.
