A nurse is reinforcing teaching with a client who is undergoing amniotic fluid assessment for the lecithin/sphingomyelin ratio. Which of the following client statements indicates an understanding of the teaching?

A.

The results can indicate a genetic disorder.

B.

This test determines how well my placenta is functioning.

C.

This test is done if there is a risk of an Rh incompatibility.

D.

The results will show if my baby's lungs are mature.

Answer and Explanation

The Correct Answer is D

Choice A rationale

 

Lecithin/sphingomyelin (L/S) ratio does not indicate genetic disorders; it's used to assess fetal lung maturity.

 

Choice B rationale

 

The test does not determine placental function. It specifically evaluates fetal lung maturity through the ratio of lecithin to sphingomyelin in amniotic fluid.

 

Choice C rationale

 

The test is not used to assess the risk of Rh incompatibility. The L/S ratio focuses on lung development rather than blood compatibility issues.

 

Choice D rationale

 

The L/S ratio assesses the baby's lung maturity, indicating if the lungs produce enough surfactant for proper function after birth.

Correct Answer is D

Explanation

Choice A rationale

An apical pulse of 66/min is within the normal range and not indicative of postpartum hemorrhage, which would typically cause an elevated heart rate due to blood loss.

Choice B rationale

A temperature of 38.3°C (101°F) could indicate infection or inflammation but is not a direct sign of postpartum hemorrhage, which primarily involves significant blood loss.

Choice C rationale

Blood pressure of 156/80 mm Hg is elevated but not directly indicative of postpartum hemorrhage, which would typically result in a drop in blood pressure due to loss of blood volume.

Choice D rationale

A respiratory rate of 32/min is significantly elevated and can be a compensatory response to hypovolemia from postpartum hemorrhage. This response occurs as the body tries to increase oxygen delivery due to blood loss.

Correct Answer is C

Explanation

Choice A rationale

A weak cry is not a typical manifestation of neonatal abstinence syndrome (NAS). NAS usually presents with a high-pitched, persistent cry due to central nervous system irritability.

Choice B rationale

Decreased muscle tone is not common in NAS. Infants with NAS often exhibit hypertonia, characterized by increased muscle tone and rigidity.

Choice C rationale

This statement is correct because an exaggerated Moro reflex is a common sign of NAS, indicating central nervous system hyperactivity in response to withdrawal from maternal drugs.

Choice D rationale

An infant with NAS does not console easily. They are often difficult to soothe due to irritability and discomfort from withdrawal symptoms. .
