A woman hospitalized with severe preeclampsia is being treated with hydralazine to control blood pressure. Which finding would lead the nurse to suspect that the client is having an adverse effect associated with this drug?

Gastrointestinal bleeding

Sweating

Tachycardia

Blurred vision

Answer and Explanation

The Correct Answer is C

Choice A Reason: This is incorrect because gastrointestinal bleeding is not an adverse effect of hydralazine, which is a vasodilator that lowers blood pressure by relaxing the smooth muscles of the blood vessels. Gastrointestinal bleeding can be caused by other conditions such as ulcers, gastritis, or hemorrhoids.

Choice B Reason: This is incorrect because sweating is not an adverse effect of hydralazine, but a normal response to vasodilation and heat loss. Sweating can also be caused by other factors such as fever, anxiety, or exercise.

Choice C Reason: This is correct because tachycardia is an adverse effect of hydralazine, which can occur as a reflex response to vasodilation and hypotension. Tachycardia can increase the cardiac workload and oxygen demand, which can be harmful for pregnant women with preeclampsia who already have impaired placental perfusion and fetal hypoxia.

Choice D Reason: This is incorrect because blurred vision is not an adverse effect of hydralazine, but a symptom of severe preeclampsia that indicates cerebral edema or ischemia. Blurred vision can also be caused by other conditions such as diabetes, glaucoma, or cataracts.

Correct Answer is C

Explanation

Choice A Reason: This is incorrect because sickle-cell anemia is a genetic disorder that affects the shape and function of red blood cells. It does not affect the AFP level, which is a protein produced by the fetus and placenta. Sickle-cell anemia can be detected by other prenatal tests, such as hemoglobin electrophoresis or DNA analysis.

Choice B Reason: This is incorrect because cardiac defects are structural abnormalities of the heart or blood vessels that affect the blood flow and oxygen delivery to the fetus. They may cause an increased AFP level, not a decreased one, as they can lead to fetal distress or edema. Cardiac defects can be detected by other prenatal tests, such as fetal echocardiography or ultrasound.

Choice C Reason: This is correct because Down syndrome is a chromosomal disorder that results from an extra copy of chromosome 21. It causes various physical and mental developmental delays and defects in the fetus. It is associated with a decreased AFP level, as well as decreased levels of human chorionic gonadotropin (hCG) and unconjugated estriol (uE3). Down syndrome can be confirmed by other prenatal tests, such as amniocentesis or chorionic villus sampling (CVS).

Choice D Reason: This is incorrect because respiratory disorders are problems that affect the breathing and gas exchange of the fetus. They may cause an increased AFP level, not a decreased one, as they can lead to fetal distress or edema. Respiratory disorders can be detected by other prenatal tests, such as fetal biophysical profile (BPP) or nonstress test (NST).

A. February 24 B. January 18 C. January 25 D. February 18

Correct Answer is D

Explanation

Choice A Reason: This is incorrect because it is too early. Naegele's rule is a formula that estimates the date of birth by adding one year, subtracting three months, and adding seven days to the date of the last menstrual period. Applying this rule to April 11 gives February 18, not February 24.

Choice B Reason: This is incorrect because it is too early. Naegele's rule gives February 18, not January 18.

Choice C Reason: This is incorrect because it is too early. Naegele's rule gives February 18, not January 25.

Choice D Reason: This is correct because it follows Naegele's rule. Adding one year, subtracting three months, and adding seven days to April 11 gives February 18.
