Nursing Elites

1. 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.

2. 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.

3. During ambulation to the bathroom, a postpartum client experiences a gush of dark red blood that soon stops. On data collection, a nurse finds the uterus to be firm, midline, and at the level of the umbilicus. Which of the following findings should the nurse interpret this data as being?

• A. Evidence of a possible vaginal hematoma
• B. An indication of a cervical or perineal laceration
• C. A normal postpartum discharge of lochia
• D. Abnormally excessive lochia rubra flow

Correct answer: C

Rationale: The nurse should interpret this data as a normal postpartum discharge of lochia. Lochia is the normal vaginal discharge after childbirth, and the gush of dark red blood upon ambulation is typical due to the pooling of blood in the vagina when lying down, which is then released upon standing. The firm, midline uterus at the level of the umbilicus indicates normal involution of the uterus postpartum. Therefore, this scenario is consistent with the expected postpartum physiological changes rather than complications like hematoma, lacerations, or abnormal excessive bleeding. Choices A, B, and D are incorrect because the described findings are more indicative of normal postpartum processes rather than complications such as vaginal hematoma, lacerations, or excessive bleeding.

4. When should a provider order a maternal serum alpha-fetoprotein (MSAFP) screening for pregnant clients?

• A. A client who has mitral valve prolapse
• B. A client who has been exposed to AIDS
• C. All pregnant clients
• D. A client who has a history of preterm labor

Correct answer: C

Rationale: Maternal serum alpha-fetoprotein (MSAFP) screening is recommended for all pregnant clients to assess the risk of neural tube defects. It is a routine screening test used to detect increased levels of alpha-fetoprotein in maternal blood, which may indicate a higher risk for conditions such as neural tube defects in the developing fetus. Therefore, all pregnant clients, regardless of their medical history or risk factors, should undergo MSAFP screening as part of routine prenatal care. Choices A, B, and D are incorrect because the MSAFP screening is not specific to certain medical conditions or histories; it is a standard screening procedure for all pregnant individuals to evaluate neural tube defect risk in the fetus.

5. A healthcare provider in a clinic is reinforcing teaching with a client of childbearing age about recommended folic acid supplements. Which of the following defects can occur in the fetus or neonate as a result of folic acid deficiency?

• A. Iron deficiency anemia
• B. Poor bone formation
• C. Macrosomic fetus
• D. Neural tube defects

Correct answer: D

Rationale: The correct answer is D: Neural tube defects. Folic acid deficiency during pregnancy can lead to neural tube defects in the fetus, affecting the brain, spine, or spinal cord development. Iron deficiency anemia (choice A) is not directly related to folic acid deficiency. Poor bone formation (choice B) is more associated with calcium and vitamin D deficiencies. Macrosomic fetus (choice C) refers to a baby with excessive birth weight and is not a typical outcome of folic acid deficiency in pregnancy. Therefore, it is crucial for individuals of childbearing age to take recommended folic acid supplements to prevent neural tube defects.
