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 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.

3. A client in a prenatal clinic is pregnant and experiencing episodes of maternal hypotension. The client asks the nurse what causes these episodes. Which of the following responses should the nurse make?

• A. This is due to an increase in blood volume.
• B. This is due to pressure from the uterus on the diaphragm.
• C. This is due to the weight of the uterus on the vena cava.
• D. This is due to increased cardiac output.

Correct answer: C

Rationale: Maternal hypotension during pregnancy is often caused by the weight of the uterus pressing on the vena cava when the client is lying on her back, which reduces blood flow to the heart. This compression can lead to a decrease in blood pressure and subsequent symptoms of hypotension. Choice A is incorrect because an increase in blood volume typically leads to increased blood pressure rather than hypotension. Choice B is incorrect as pressure from the uterus on the diaphragm is not a common cause of maternal hypotension. Choice D is incorrect because increased cardiac output would not directly cause maternal hypotension.

4. A client in labor is having contractions 4 minutes apart. Which of the following patterns should the nurse expect on the fetal monitoring tracing?

• A. Contractions that last for 60 seconds each with a 4-minute rest between contractions
• B. A contraction that lasts 4 minutes followed by a period of relaxation
• C. Contractions that last for 60 seconds each with a 3-minute rest between contractions
• D. Contractions that last 45 seconds each with a 3-minute rest between contractions

Correct answer: C

Rationale: The correct answer is C. When contractions are 4 minutes apart, it means there are 4 minutes from the start of one contraction to the start of the next. If each contraction lasts 60 seconds, there will be a 3-minute rest period between contractions. This allows for adequate uterine relaxation and recovery before the next contraction begins. Choice A is incorrect because it suggests a 4-minute rest between contractions, which is not accurate. Choice B is incorrect as contractions lasting 4 minutes continuously without rest would be concerning. Choice D is incorrect as it suggests 45-second contractions instead of 60-second contractions.

5. A client who is at 22 weeks gestation is being educated by a nurse about the amniocentesis procedure. Which of the following statements should the nurse make?

• A. You will lie on your right side during the procedure.
• B. You should not eat anything for 24 hours before the procedure.
• C. You should empty your bladder before the procedure.
• D. The test is performed to determine gestational age.

Correct answer: C

Rationale: The correct answer is C. The nurse should advise the client to empty her bladder before an amniocentesis to minimize the risk of bladder puncture during the procedure. This precaution helps ensure the safety and accuracy of the procedure by reducing potential complications related to bladder puncture. Choices A, B, and D are incorrect because lying on the right side, fasting for 24 hours, and determining gestational age are not relevant instructions for an amniocentesis procedure.
