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 client with pregestational type 1 diabetes mellitus is being taught by a nurse about management during pregnancy. Which of the following statements by the client indicates an understanding of the teaching?

• A. I should aim to maintain my fasting blood glucose between 100 and 120.
• B. I should engage in moderate exercise for 30 minutes if my blood glucose is 250 or higher.
• C. I will continue taking my insulin if I experience nausea and vomiting.
• D. I will avoid exercise if my blood glucose exceeds 250.

Correct answer: C

Rationale: The correct answer is C. It is essential for a client with pregestational type 1 diabetes mellitus to continue taking insulin as prescribed even if they experience nausea and vomiting. This is crucial to prevent fluctuations in blood glucose levels that could lead to serious complications. Choice A is incorrect because the fasting blood glucose target for pregnant women with diabetes is usually lower. Choice B is incorrect as engaging in exercise when blood glucose is high is not recommended. Choice D is incorrect as avoiding exercise is not the appropriate approach when blood glucose levels are elevated.

3. During active labor, a nurse notes tachycardia on the external fetal monitor tracing. Which of the following conditions should the nurse identify as a potential cause of the heart rate?

• A. Maternal fever
• B. Fetal heart failure
• C. Maternal hypoglycemia
• D. Fetal head compression

Correct answer: A

Rationale: Maternal fever can lead to fetal tachycardia due to the transmission of maternal fever to the fetus. This can result in an increased fetal heart rate, making it the correct potential cause in this scenario. Fetal heart failure (choice B) would typically present with bradycardia rather than tachycardia, making it an incorrect choice. Maternal hypoglycemia (choice C) is more likely to cause fetal distress rather than tachycardia. Fetal head compression (choice D) may lead to decelerations in the fetal heart rate pattern, but not necessarily tachycardia.

4. A healthcare provider is preparing to administer vitamin K by IM injection to a newborn. The medication should be administered into which of the following muscles?

• A. Vastus lateralis
• B. Ventrogluteal
• C. Dorsogluteal
• D. Deltoid

Correct answer: A

Rationale: Vitamin K is typically administered in the vastus lateralis muscle of a newborn to prevent bleeding disorders. The vastus lateralis muscle is the preferred site for IM injections in infants due to its size and accessibility, allowing for easy and safe administration. The ventrogluteal and dorsogluteal sites are more commonly used in adults due to better muscle mass and less risk of injury to nearby structures. The deltoid muscle is typically used for older children and adults for IM injections, as it is a well-developed muscle suitable for injections in these populations.

5. A client is in labor and reports increasing rectal pressure. She is experiencing contractions 2 to 3 minutes apart, each lasting 80 to 90 seconds, and a vaginal examination reveals that her cervix is dilated to 9 cm. The client is in which of the following phases of labor?

• A. Active
• B. Transition
• C. Latent
• D. Descent

Correct answer: B

Rationale: The client is in the transition phase of labor, characterized by cervical dilatation of 8 to 10 cm and contractions every 2 to 3 minutes, each lasting 45 to 90 seconds. In this phase, the cervix is nearly fully dilated, preparing the client for the pushing stage. The active phase of labor typically involves cervical dilatation from 4 to 7 cm, whereas the latent phase is the early phase of labor when the cervix dilates from 0 to 3 cm. Descent is not a phase of labor but rather refers to the movement of the fetus through the birth canal during the second stage of labor.
