ATI RN Maternal Newborn level 3 Final Exam 2023 (All Correct Answers). Maternal-Child Nursing -Nurselytic

Correct Answer: B

Rationale: The correct answer is B: This test will determine adequacy of placental perfusion. The non-stress test is used to assess fetal well-being by monitoring fetal heart rate in response to fetal movement. It helps determine if the placenta is providing enough oxygen and nutrients to the fetus. This is crucial in determining the adequacy of placental perfusion and ensuring the baby's health. The other choices are incorrect because:
A) Fetal lung maturity is typically confirmed through other tests like an amniocentesis;
C) Detecting fetal infection would require different diagnostic tests;
D) Predicting maternal readiness for labor is not the purpose of a non-stress test.

Correct Answer: B

Rationale: The correct answer is B: Contact precautions. MRSA is typically spread through direct contact with an infected person or contaminated surfaces. By implementing contact precautions, the nurse can prevent the transmission of MRSA to other patients or healthcare workers. Droplet precautions are used for infections spread through respiratory droplets, such as influenza. Airborne precautions are used for diseases like tuberculosis that are transmitted through small droplets that remain in the air. Protective environment is used for immunocompromised patients to protect them from outside infections.
Therefore, in this case, contact precautions are the most appropriate choice to prevent the spread of MRSA.

Correct Answer: B

Rationale: The correct answer is B: 12/27. Nagele's rule is used to estimate the due date by adding 7 days and subtracting 3 months from the first day of the last menstrual period. In this case, March 20 + 7 days = March 27.
Then, subtracting 3 months gives us December 27 as the estimated due date.
Choice A (03/20) is incorrect because it is the same as the last menstrual period date and not applying Nagele's rule.

Choices C (11/27) and D (10/03) are incorrect as they do not follow the correct calculation method.

Correct Answer: B

Rationale: The correct answer is B. The nurse should assess the client at 32 weeks of gestation reporting floating spots first because this symptom could indicate a serious condition called preeclampsia, characterized by high blood pressure and protein in the urine. This condition can be life-threatening for both the mother and baby if not managed promptly. Assessing this client first allows for early detection and intervention, reducing the risk of complications.



Choices A, C, and D present symptoms that are common in pregnancy but do not indicate immediate danger. Urinary frequency in early pregnancy (
A), leg cramps in late pregnancy (
C), and periodic numbness in fingers (
D) are typically benign and can be managed with routine interventions. Prioritizing the client with potential signs of preeclampsia (
B) ensures the safety and well-being of both the client and the baby.

Correct Answer: D

Rationale: The correct answer is D: Chest circumference 2 cm smaller than the head circumference. This is expected in a newborn as the head circumference is typically larger than the chest circumference due to the size of the brain. This difference in measurements is known as the head-to-chest ratio and is a normal finding in a newborn. Bulging fontanels (
A) may indicate increased intracranial pressure, nasal flaring (
B) can be a sign of respiratory distress, and a length of 40 cm (
C) is within the normal range but not specifically related to the chest circumference.
