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 correct answer is B: Lecithin/sphingomyelin (L/S) ratio. This test is used to assess fetal lung maturity by determining the ratio of two substances present in amniotic fluid. An L/S ratio of 2:1 or higher indicates mature fetal lungs, reducing the risk of respiratory distress syndrome in preterm infants.
A: Alpha-fetoprotein (AFP) is used to screen for neural tube defects, not fetal lung maturity.
C: Kleihauer-Betke test is used to detect fetal-maternal hemorrhage.
D: Indirect Coombs' test is used to detect antibodies in maternal blood that may attack fetal red blood cells, not assess fetal lung maturity.
In summary, the L/S ratio test is the most appropriate choice to assess fetal lung maturity during preterm labor, as it directly correlates with the development of the fetal lungs.

A healthcare provider is reviewing the health record of a client who is pregnant. The provider indicated the client exhibits probable signs of pregnancy. Which of the following findings should the provider expect? (Select all that apply)
- A. Chadwick's sign
- B. Goodell's sign
- C. Ballottement
- D. All of the above
Correct Answer: D
Rationale: The correct answer is D because all three signs (Chadwick's sign, Goodell's sign, and Ballottement) are probable signs of pregnancy. Chadwick's sign refers to bluish discoloration of the cervix, Goodell's sign is softening of the cervix, and Ballottement is a palpable rebound of the fetus against the examiner's fingers. These signs are indicative of pregnancy and are commonly observed in pregnant individuals. Therefore, the provider should expect to see all these findings in a pregnant client. The other choices (A, B, and C) are incorrect because each of these signs individually is a probable sign of pregnancy, and the question asks for all the expected findings, not just one or two of them.
A client who is at 6 weeks of gestation is being educated about common discomforts of pregnancy. Which of the following findings should the individual include? (Select all that apply)
- A. Breast tenderness
- B. Urinary frequency
- C. Epistaxis
- D. All of the above
Correct Answer: D
Rationale: The correct answer is D: All of the above. At 6 weeks of gestation, common discomforts include breast tenderness due to hormonal changes, urinary frequency from increased blood flow to kidneys, and epistaxis (nosebleeds) due to increased blood volume and vessel fragility. Therefore, all options are relevant and should be included in the education. Other choices are incorrect because they do not encompass all the common discomforts experienced during early pregnancy.
A nurse is preparing to perform Leopold maneuvers for a client. Identify the sequence the nurse should follow.
- A. Palpate the fundus to identify the fetal part.
- B. Determine the location of the fetal back.
- C. Palpate for the fetal part presenting at the inlet.
- D. All of the Above
Correct Answer: D
Rationale: The correct sequence for performing Leopold maneuvers is to first palpate the fundus to identify the fetal part (A), then determine the location of the fetal back (B), and finally palpate for the fetal part presenting at the inlet (C). Choosing option D (All of the Above) is correct because it encompasses all the necessary steps in the correct order to perform Leopold maneuvers effectively. Palpating the fundus helps identify the presenting part, determining the location of the fetal back provides information on the fetal lie, and palpating for the presenting part at the inlet helps confirm the position of the fetus. The other choices are incorrect because they do not provide the complete sequence required for performing Leopold maneuvers accurately.
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: The correct answer is B: Ectopic pregnancy. Given the client's symptoms of right-sided lower quadrant abdominal pain, vaginal bleeding, missed menstrual cycle, and presence of an intrauterine device, these are classic signs of an ectopic pregnancy. Ectopic pregnancy occurs when a fertilized egg implants outside the uterus, commonly in the fallopian tube, leading to abdominal pain and vaginal bleeding. The other choices are incorrect because:
A: Missed abortion would typically present with cramping, bleeding, and passage of tissue.
C: Severe preeclampsia is characterized by high blood pressure and proteinuria, not the symptoms described.
D: Hydatidiform mole would typically present with vaginal bleeding and uterine enlargement, but not the sharp abdominal pain described.
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 calculate the mL/hr for the IV infusion pump, we need to use the formula: (Desired dose in mg/hr * Volume of solution in mL) / Concentration of solution in mg/mL.
Given:
Desired dose = 2 g/hr = 2000 mg/hr
Volume of solution = 500 mL
Concentration of solution = 20 g in 500 mL = 20,000 mg in 500 mL = 40 mg/mL
Now, plug these values into the formula:
(2000 mg/hr * 500 mL) / 40 mg/mL = 25,000 mL/hr
Round this to the nearest whole number, which is 25,000 mL/hr ≈ 50 mL/hr. Therefore, the IV infusion pump should be set to administer 50 mL/hr, making choice C the correct answer.
Option A (60 mL/hr) and Option D (80 mL/hr) are incorrect as they do not match the calculated value. Option
