NCLEX-RN Exam Questions - Part 2
1. Pregnant women with diabetes often have problems related to the effectiveness of insulin in controlling their glucose levels during their second half of pregnancy.The nurse teaches the client that this is due to:
A) Decreased glomerular filtration and increased tubular absorption
B) Decreased estrogen levels
C) Decreased progesterone levels
D) Increased human placental lactogen levels
2. Diabetes during pregnancy requires tight metabolic control of glucose levels to prevent perinatal mortality. When evaluating the pregnant client, the nurse knows the recommended serum glucose range during pregnancy is:
A) 70 mg/dL and 120 mg/dL
B) 100 mg/dL and 200 mg/dL
C) 40 mg/dL and 130 mg/dL
D) 90 mg/dL and 200 mg/dL
3. When assessing fetal heart rate status during labor, the monitor displays late decelerations with tachycardia and decreasing variability. What action should the nurse take?
A) Continue monitoring because this is a normal occurrence.
B) Turn client on right side.
C) Decrease IV fluids.
D) Report to physician or midwife.
4. A client has been diagnosed as being preeclamptic. The physician orders magnesium sulfate. Magnesium sulfate (MgSO4) is used in the management of preeclampsia for:
A) Prevention of seizures
B) Prevention of uterine contractions
C) Sedation
D) Fetal lung protection
5. The predominant purpose of the first Apgar scoring of a newborn is to:
A) Determine gross abnormal motor function
B) Obtain a baseline for comparison with the infant - s future adaptation to the environment
C) Evaluate the infant - s vital functions
D) Determine the extent of congenital malformations
A) Decreased glomerular filtration and increased tubular absorption
B) Decreased estrogen levels
C) Decreased progesterone levels
D) Increased human placental lactogen levels

D) Determine the extent of congenital malformations
1. Right Answer: D
Explanation: (A) There is a rise in glomerular filtration rate in the kidneys in conjunction with decreased tubular glucose reabsorption, resulting in glycosuria. (B) Insulin is inhibited by increased levels of estrogen. (C) Insulin is inhibited by increased levels of progesterone. (D) Human placental lactogen levels increase later in pregnancy. This hormonal antagonist reduces insulins effectiveness, stimulates lipolysis, and increases the circulation of free fatty acids.
2. Right Answer: A
Explanation: (A) The recommended range is 70120 mg/dL to reduce the risk of perinatal mortality. (B, C, D) These levels are not recommended. The higher the blood glucose, the worse the prognosis for the fetus. Hypoglycemia can also have detrimental effects on the fetus.
3. Right Answer: D
Explanation: (A) This is not a normal occurrence. Late decelerations need prompt intervention for immediate infant recovery. (B) To increase O2 perfusion to the unborn infant, the mother should be placed on her left side. (C) IV fluids should be increased, not decreased. (D) Immediate action is warranted, such as reporting findings, turning mother on left side, administering O2, discontinuing oxytocin (Pitocin), assessing maternal blood pressure and the labor process, preparing for immediate cesarean delivery, and explaining plan of action to client.
4. Right Answer: A
Explanation: (A) MgSO4 is classified as an anticonvulsant drug. In preeclampsia management, MgSO4 is used for prevention of seizures. (B) MgSO4 has been used to inhibit hyperactive labor, but results are questionable. (C) Negative side effects such as respiratory depression should not be confused with generalized sedation. (D)MgSO4 does not affect lung maturity. The infant should be assessed for neuromuscular and respiratory depression.
5. Right Answer: C
Explanation: (A) Apgar scores are not related to the infants care, but to the infants physical condition. (B) Apgar scores assess the current physical condition of the infant and are not related to future environmental adaptation. (C) The purpose of the Apgar system is to evaluate the physical condition of the newborn at birth and to determine if there is an immediate need for resuscitation. (D) Congenital malformations are not one of the areas assessed with Apgar scores.
