Nursing Elites

1. A healthcare professional is preparing to administer magnesium sulfate 2 g/hr IV to a client who is in preterm labor. Available is 20 g of magnesium sulfate in 500 mL of dextrose 5% in water (D5W). How many mL/hr should the IV infusion pump be set to administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

• A. 60
• B. 30
• C. 50
• D. 80

Correct answer: C

Rationale: To administer magnesium sulfate 2 g/hr IV, the healthcare professional should set the IV infusion pump to administer 50 mL/hr. The calculation is as follows: 20 g / 500 mL = 2 g / X mL, X = 50 mL/hr. Choice A (60 mL/hr) is incorrect as it does not match the calculated rate. Choice B (30 mL/hr) is incorrect as it is half of the calculated rate. Choice D (80 mL/hr) is incorrect as it is higher than the calculated rate.

2. When caring for clients in a prenatal clinic, a nurse should report which client's weight gain to the provider?

• A. 1.8 kg (4 lb) weight gain in the first trimester
• B. 3.6 kg (8 lb) weight gain in the first trimester
• C. 6.8 kg (15 lb) weight gain in the second trimester
• D. 11.3 kg (25 lb) weight gain in the third trimester

Correct answer: B

Rationale: A weight gain of 3.6 kg (8 lb) in the first trimester is excessive and should be reported to the provider for further evaluation. Excessive weight gain in the first trimester can be a sign of potential issues that need monitoring and intervention to ensure the well-being of both the mother and the baby. Choices A, C, and D represent weight gains that are within normal ranges for the respective trimesters and do not raise immediate concerns for reporting to the provider.

3. A nurse in the emergency department is caring for a client who reports abrupt, sharp, right-sided lower quadrant abdominal pain and bright red vaginal bleeding. The client states, 'I missed one menstrual cycle and cannot be pregnant because I have an intrauterine device.' The nurse should suspect which of the following?

• A. Missed abortion
• B. Ectopic pregnancy
• C. Severe preeclampsia
• D. Hydatidiform mole

Correct answer: B

Rationale: Ectopic pregnancy should be suspected in clients with abrupt, sharp, right-sided lower quadrant abdominal pain and bright red vaginal bleeding, especially if they have an intrauterine device (IUD). In this case, the client's symptoms are classic for ectopic pregnancy, where the fertilized egg implants outside the uterus, commonly in the fallopian tube. Missed abortion (choice A) refers to a nonviable embryo or fetus in the uterus, which is not consistent with the client's presentation. Severe preeclampsia (choice C) is characterized by hypertension and proteinuria, not the symptoms described. Hydatidiform mole (choice D) presents with vaginal bleeding but typically lacks abdominal pain and is not related to the presence of an IUD.

4. A client who is pregnant states that her last menstrual period was April 1st. What is the client's estimated date of delivery?

• A. January 8
• B. January 15
• C. February 8
• D. February 15

Correct answer: A

Rationale: To calculate the estimated date of delivery, add 7 days to the first day of the last menstrual period (April 1st), which gives April 8th. Then, count forward 9 months from April 8th, leading to January 8th as the estimated date of delivery. Choice A is correct. Choice B is incorrect because it is exactly 9 months from the last menstrual period without accounting for the additional 7 days. Choices C and D are incorrect as they fall in February, which is beyond the 9-month period from the last menstrual period.

5. During preterm labor, a client is scheduled for an amniocentesis. The nurse should review which of the following tests to assess fetal lung maturity?

• A. Alpha-fetoprotein (AFP)
• B. Lecithin/sphingomyelin (L/S) ratio
• C. Kleihauer-Betke test
• D. Indirect Coombs' test

Correct answer: B

Rationale: The Lecithin/sphingomyelin (L/S) ratio is a test used to evaluate fetal lung maturity. An L/S ratio greater than 2:1 indicates fetal lung maturity. This test helps in determining the risk of respiratory distress syndrome in the newborn. Alpha-fetoprotein (AFP) is used in screening for neural tube defects, not for assessing lung maturity. The Kleihauer-Betke test is used to detect fetal-maternal hemorrhage, not fetal lung maturity. The Indirect Coombs' test is used to identify the presence of antibodies in the mother's blood that could attack fetal red blood cells, not for assessing lung maturity.
