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. During the admission assessment of a newborn, which anatomical landmark should be used for measuring the newborn's chest circumference?

• A. Sternal notch
• B. Nipple line
• C. Xiphoid process
• D. Fifth intercostal space

Correct answer: B

Rationale: When measuring a newborn's chest circumference, the appropriate anatomical landmark to use is the nipple line. This point is consistent and allows for accurate and standardized measurements across all newborn assessments. The sternal notch is not typically used for chest circumference measurements in newborns. The xiphoid process is located at the lower end of the sternum and is not an appropriate landmark for chest circumference measurement. The fifth intercostal space is typically used for locating the point of maximal impulse (PMI) during cardiac assessments, not for measuring chest circumference.

3. A client is to receive oxytocin to augment labor. Which finding contraindicates the initiation of the oxytocin infusion and should be reported to the provider?

• A. Late decelerations
• B. Moderate variability of the FHR
• C. Cessation of uterine dilation
• D. Prolonged active phase of labor

Correct answer: A

Rationale: Late decelerations are indicative of uteroplacental insufficiency, which can be exacerbated by oxytocin administration, potentially compromising fetal well-being. Therefore, detecting late decelerations should prompt immediate reporting to the provider to prevent harm to the fetus. Choices B, C, and D are not contraindications for initiating oxytocin infusion. Moderate variability of the FHR is a reassuring sign of fetal well-being, cessation of uterine dilation may indicate a pause in labor progress but does not contraindicate oxytocin, and prolonged active phase of labor may necessitate oxytocin administration to augment contractions and progress labor.

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 the third trimester of pregnancy, which of the following findings should a nurse recognize as an expected physiologic change?

• A. Gradual lordosis
• B. Increased abdominal muscle tone
• C. Posterior neck flexion
• D. Decreased mobility of pelvic joints

Correct answer: A

Rationale: During pregnancy, gradual lordosis is a common adaptation to the growing fetus. Lordosis refers to an increased lumbar curve in the spine, which helps to shift the center of gravity forward, supporting the enlarging uterus. This change is necessary to maintain balance and reduce strain on the back muscles as the pregnancy progresses. Increased abdominal muscle tone, posterior neck flexion, and decreased mobility of pelvic joints are not typical physiological changes during pregnancy. Increased abdominal muscle tone is not expected as the abdominal muscles tend to stretch and separate to accommodate the growing fetus. Posterior neck flexion is not a common finding and decreased mobility of pelvic joints is not an expected change and can cause discomfort.
