Nursing Elites

1. A healthcare provider is assessing a newborn who has a coarctation of the aorta. Which of the following should the provider recognize as a clinical manifestation of coarctation of the aorta?

• A. Increased blood pressure in the arms with decreased blood pressure in the legs
• B. Decreased blood pressure in the arms with increased blood pressure in the legs
• C. Increased blood pressure in both the arms and the legs
• D. Decreased blood pressure in both the arms and the legs

Correct answer: A

Rationale: The correct answer is increased blood pressure in the arms with decreased blood pressure in the legs. Coarctation of the aorta is a congenital heart defect characterized by a narrowing of the aorta, leading to increased blood pressure in the upper extremities and decreased blood pressure in the lower extremities due to decreased blood flow beyond the narrowing. Choice B is incorrect because coarctation of the aorta does not lead to increased blood pressure in the legs. Choice C is incorrect because increased blood pressure in both the arms and legs is not a typical manifestation of coarctation of the aorta. Choice D is incorrect because decreased blood pressure in both the arms and legs is not characteristic of coarctation of the aorta.

2. A nurse is admitting a term newborn following a cesarean birth. The nurse observes that the newborn's skin is slightly yellow. This finding indicates the newborn is experiencing a complication related to which of the following?

• A. Maternal/newborn blood group incompatibility
• B. Absence of vitamin K
• C. Physiologic jaundice
• D. Maternal cocaine abuse

Correct answer: A

Rationale: The yellow skin observed in the newborn suggests jaundice. Maternal/newborn blood group incompatibility is a common cause of jaundice in newborns. This occurs when the mother and baby have different blood types, leading to the baby's immune system attacking the red blood cells, causing jaundice. Physiologic jaundice, which is a normal process due to the breakdown of red blood cells in newborns, typically presents after the first 24 hours of life. Absence of vitamin K leads to bleeding issues, not jaundice. Maternal cocaine abuse does not directly cause jaundice in newborns.

3. 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.

4. A client has postpartum psychosis. Which of the following actions is the nurse's priority?

• A. Reinforce the importance of taking antipsychotics as prescribed
• B. Ask the client if they have thoughts of harming themselves or their infant
• C. Monitor the infant for signs of failure to thrive
• D. Check the client's medical record for a history of bipolar disorder

Correct answer: B

Rationale: In a situation where a client has postpartum psychosis, the priority action for the nurse is to ask the client if they have thoughts of harming themselves or their infant. This is crucial to assess the risk of harm and ensure the safety of the client and the infant. While reinforcing the importance of taking antipsychotics as prescribed is essential for treatment, safety concerns take precedence. Monitoring the infant for signs of failure to thrive is important for the infant's well-being but is not the priority when the immediate safety of the client and infant is at risk. Checking the client's medical record for a history of bipolar disorder is relevant for understanding the client's medical history but is not the priority when addressing current safety concerns.

5. A healthcare provider is assessing a newborn 1 hr after birth. Which of the following respiratory rates is within the expected reference range for a newborn?

• A. 22/min
• B. 48/min
• C. 100/min
• D. 110/min

Correct answer: B

Rationale: The expected respiratory rate for a newborn is between 30 to 60 breaths per minute. A rate of 48 breaths per minute falls within this range, indicating normal respiratory function for a newborn. Choice A (22/min) is below the expected range, Choices C (100/min) and D (110/min) are above the expected range for a newborn's respiratory rate.
