Nursing Elites

1. 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.

2. A nurse at an antepartum clinic is caring for a client who is at 4 months of gestation. The client reports continued nausea, vomiting, and scant, prune-colored discharge. The client has experienced no weight loss and has a fundal height larger than expected. Which of the following complications should the nurse suspect?

• A. Hyperemesis gravidarum
• B. Threatened abortion
• C. Hydatidiform mole
• D. Preterm labor

Correct answer: C

Rationale: In this scenario, the symptoms of continued nausea, vomiting, scant prune-colored discharge, and a fundal height larger than expected at 4 months of gestation suggest a possible hydatidiform mole. Hyperemesis gravidarum (choice A) typically presents with severe nausea, vomiting, weight loss, and electrolyte imbalances. Threatened abortion (choice B) is characterized by vaginal bleeding with or without cramping but does not typically present with prune-colored discharge. Preterm labor (choice D) manifests with regular uterine contractions leading to cervical changes and can occur later in pregnancy.

3. A client who received carboprost for postpartum hemorrhage is being assessed by a nurse. Which of the following findings is an adverse effect of this medication?

• A. Hypertension
• B. Hypothermia
• C. Constipation
• D. Muscle weakness

Correct answer: A

Rationale: The correct answer is A: Hypertension. Carboprost is a vasoconstrictor medication used to control postpartum hemorrhage by contracting the uterus. One of the adverse effects of carboprost is hypertension due to its vasoconstrictive properties. Hypertension can occur as a result of increased peripheral vascular resistance. Choices B, C, and D are incorrect. Hypothermia, constipation, and muscle weakness are not typically associated with the administration of carboprost. It is crucial for the nurse to monitor the client's blood pressure closely while on carboprost to promptly detect and manage hypertension.

4. An adolescent is being taught about levonorgestrel contraception by a school nurse. What information should the nurse include in the teaching?

• A. You should take the medication within 72 hours following unprotected sexual intercourse.
• B. Do not take this medication if you are on an oral contraceptive.
• C. If you do not start your period within 5 days of taking this medication, you will need a pregnancy test.
• D. One dose of this medication will prevent pregnancy for 14 days after taking it.

Correct answer: A

Rationale: Levonorgestrel is an emergency contraceptive that works by inhibiting ovulation to prevent conception. It is most effective when taken as soon as possible within 72 hours following unprotected sexual intercourse. Therefore, the nurse should instruct the adolescent to take the medication promptly to maximize its effectiveness. Choice B is incorrect because levonorgestrel can be used even if the individual is on oral contraceptives. Choice C is incorrect as the efficacy of levonorgestrel is not determined by the onset of menstruation. Choice D is incorrect because levonorgestrel is a single-dose emergency contraceptive and does not provide protection for 14 days after ingestion.

5. A client is scheduled for a cesarean birth based on fetal lung maturity. Which finding indicates that the fetal lungs are mature?

• A. Absence of Phosphatidylglycerol (PG)
• B. Biophysical profile score of 8
• C. Lecithin/sphingomyelin (L/S) ratio of 2:1
• D. Reactive nonstress test

Correct answer: C

Rationale: An L/S ratio of 2:1 indicates fetal lung maturity, as it signifies the presence of surfactant in the amniotic fluid, which helps with lung expansion and prevents collapse at the end of expiration. The absence of PG indicates immaturity of the fetal lungs, as PG appears in the amniotic fluid during the later stages of lung maturation. Biophysical profile scores and nonstress tests are assessments of fetal well-being and do not directly indicate fetal lung maturity. Therefore, choice C is the correct answer.
