The nurse knows that a lecithin/sphingomyelin (L/S) ratio finding of 2:1 on amniotic fluid means:

1. Fetal lungs are still immature.
2. The fetus has a congenital anomaly.
3. Fetal lungs are mature.
4. The fetus is small for gestational age.

Question 2

The nurse is serving on a panel to evaluate the hospital staff's reliance on evidence-based practice in their decision-making processes.

Which practices characterize the basic competencies related to evidence-based practice? Note: Credit will be given only if all correct choices and no incorrect choices are selected. Select all that apply. 1. Recognizing which clinical practices are supported by good evidence
2. Recognizing and including clinical practice supported by intuitive evidence
3. Using data in clinical work to evaluate outcomes of care
4. Including quality-improvement measures in clinical practice
5. Appraising and integrating scientific bases into practice

Answer to Question 1

3
Rationale 1: Early in pregnancy, the sphingomyelin concentration in amniotic fluid is greater than the concentration of lecithin, and so the L/S ratio is low if the fetus's lungs are immature, which is not the case in this instance.
Rationale 2: The L/S ratio isn't a measurement for congenital anomalies or size of the fetus.
Rationale 3: A 2:1 L/S ratio indicates that the risk of respiratory distress syndrome (RDS) is very low and that the fetus's lungs are mature.
Rationale 4: The L/S ratio isn't a measurement for congenital anomalies or size of the fetus.

Answer to Question 2

1,3,5
Rationale 1: Recognizing which clinical practices are supported by sound evidence is a basic competency related to evidence-based practice.
Rationale 2: Including clinical practice supported by intuitive evidence is not a basic competency related to evidence-based practice.
Rationale 3: Using data in clinical work to evaluate outcomes of care is one of the basic competencies related to evidence-based practice.
Rationale 4: Including quality-improvement measures is a form of evidence that can be useful in making clinical practice decisions, but it is not a basic competency related to evidence-based practice.
Rationale 5: Appraising and integrating scientific bases into practice is one of the characteristics of the basic competencies related to evidence-based practice.
