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 A
Explanation
Choice A Reason: This is the correct answer because it is an empathetic and supportive response that acknowledges the client's loss and grief. This is an empathetic and supportive response that acknowledges the client's loss and grief. The other choices are inappropriate because they are insensitive, dismissive, or inaccurate.
Choice B Reason: This is an inappropriate answer because it implies that the nurse does not understand or care about the client's emotional state. It also suggests that the client has no Reason to cry, which is invalidating and hurtful.
Choice C Reason: This is an inappropriate answer because it focuses on the physical pain rather than the emotional pain of the client. It also implies that the nurse wants to avoid dealing with the client's feelings and just give them a medication to make them stop crying.
Choice D Reason: This is an inappropriate answer because it is inaccurate and misleading. A spontaneous abortion, also known as a miscarriage, occurs when a pregnancy ends before 20 weeks of gestation. At this stage, the baby is already formed and has a heartbeat, organs, and limbs. Saying that a baby still wasn't formed in the womb is false and insensitive to the client's loss.
Correct Answer is A
Explanation
Choice A: Hemodilution of pregnancy is a normal physiological phenomenon that occurs when the plasma volume increases more than the red blood cell mass, resulting in a lower hemoglobin concentration. The normal hemoglobin range for pregnant women in the second trimester is 10.5 to 14 g/dL.
Choice B: A multiple gestation pregnancy may cause a higher hemoglobin level due to increased erythropoietin production by the placenta. The normal hemoglobin range for pregnant women with twins in the second trimester is 12 to 16 g/dL.
Choice C: Greater-than-expected weight gain is not related to hemoglobin level. Weight gain during pregnancy depends on various factors such as pre-pregnancy weight, nutrition, activity level, and fetal growth.
Choice D: Iron-deficiency anemia is a condition where the hemoglobin level is below the normal range due to inadequate iron intake or absorption, blood loss, or increased iron demand. The signs and symptoms of iron-deficiency anemia include fatigue, pallor, weakness, shortness of breath, and pica.
