Assessment of a pregnant woman and her fetus reveals tachycardia and hypertension. There is also evidence suggesting vasoconstriction. The nurse would question the woman about use of which substance?
Marijuana
Cocaine
Nicotine
Caffeine
Heroin
The Correct Answer is B
Choice A Reason: This is incorrect because marijuana is a psychoactive substance that affects the central nervous system and can cause euphoria, relaxation, altered perception, and impaired memory. It does not cause tachycardia, hypertension, or vasoconstriction in pregnant women or their fetuses.
Choice B Reason: This is correct because cocaine is a stimulant substance that affects the cardiovascular system and can cause tachycardia, hypertension, vasoconstriction, arrhythmias, and ischemia in pregnant women or their fetuses. It can also increase the risk of placental abruption, preterm labor, intrauterine growth restriction, and fetal death.
Choice C Reason: This is incorrect because nicotine is a stimulant substance that affects the respiratory system and can cause bronchodilation, increased heart rate, and increased blood pressure in pregnant women or their fetuses. However, it does not cause vasoconstriction, but rather vasodilation.
Choice D Reason: This is incorrect because caffeine is a stimulant substance that affects the central nervous system and can cause alertness, insomnia, anxiety, and increased urine output in pregnant women or their fetuses. It does not cause tachycardia, hypertension, or vasoconstriction in moderate doses.
Choice E Reason: This is incorrect because heroin is an opioid substance that affects the central nervous system and can cause euphoria, sedation, analgesia, and respiratory depression in pregnant women or their fetuses. It does not cause tachycardia, hypertension, or vasoconstriction.

Correct Answer is ["415"]
Explanation
To calculate the amount of NG drainage, the nurse should subtract the amount of irrigation fluid from the amount of fluid in the NG canister. The irrigation fluid is not part of the drainage, but rather a way to keep the NG tube patent and prevent clogging.
The amount of irrigation fluid is 30 mL x 2 = 60 mL.
The amount of fluid in the NG canister is 475 mL.
Therefore, the amount of NG drainage is 475 mL - 60 mL = 415 mL.
The answer should be rounded to the nearest whole number and use a leading zero if it applies. Do not use a trailing zero.
Therefore, the final answer is 415 mL.
Correct Answer is ["31"]
Explanation
The correct answer is 31 gtts/min. To calculate the infusion rate, the nurse should use the following formula:
Infusion rate (gtts/min) = Volume (mL) x Drop factor (gtts/mL) / Time (min)
Plugging in the given values, we get:
Infusion rate (gtts/min) = 1000 mL x 15 gtts/mL / 480 min
Infusion rate (gtts/min) = 31.25 gtts/min
Rounding to the nearest whole number, we get 31 gtts/min.
