ATI NCLEX-RN Practice Questions Questions
Extract:
Question 1 of 5
A female client at 36 weeks' gestation has been treated successfully for premature labor for 4 weeks. She has begun having uterine contractions today and has been admitted to the labor and delivery suite. Her amniocentesis results reveal a lecithin/sphingomyelin (L/S) ratio of 2 and positive phosphatidylglycerol (PG). These lab values indicate:
Correct Answer: D
Rationale: Placental maturity is assessed by a biophysical profile. L/S ratio and presence of phosphatidylglycerol are not used to determine fetal asphyxia. A biophysical profile score of 6 may indicate this condition. Cord compression is not reflected by the L/S ratio or presence of phosphatidylglycerol. Variable decelerations observed through electronic fetal monitoring could reflect umbilical cord compression. An L/S ratio >2 and the presence of phosphatidylglycerol in amniotic fluid indicate fetal lung maturity.
Question 2 of 5
When assessing residual volume in tube feeding, the feeding should be delayed if the amount of gastric contents (residual) exceeds:
Correct Answer: D
Rationale: Tube feedings should be withheld and physician notified for residual volumes of 50-100 mL.
Question 3 of 5
Which of the following signs and symptoms indicates a tension pneumothorax as compared to an open pneumothorax?
Correct Answer: C
Rationale: The tension pneumothorax acts like a one-way valve so that the pneumothorax increases with each breath. Eventually, it occupies enough space to shift mediastinal tissue toward the unaffected side away from the midline. Tracheal deviation, movement of point of maximum impulse, and decreased cardiac output will occur. The other three options will occur in both types of pneumothorax.
Question 4 of 5
A client has had amniocentesis. One of the tests performed on the amniotic fluid is a lecithin/sphingomyelin (L/S) ratio. The results show a ratio of 1:1. This is indicative of:
Correct Answer: A
Rationale: At about 30-32 weeks' gestation, the amounts of the surfactants, lecithin, and sphingomyelin become equal. As the fetal lungs mature, the concentration of lecithin begins to exceed that of sphingomyelin. At 35 weeks, the L/S ratio is 2:1. Respiratory distress syndrome is unlikely if birth occurs at this time.
Question 5 of 5
A 5-year-old child has suffered second-degree thermal burns over 30% of her body. Forty-eight hours after the burn injury, the nurse must begin to monitor the child for which one of the following complications?
Correct Answer: B
Rationale: Fluid volume deficit resulting from fluid shifts to the interstitial spaces occurs in the first 48 hours. Forty-eight hours to 72 hours after the burn injury and fluid resuscitation, capillary permeability is restored and fluid requirements decrease. Interstitial fluid returns rapidly to the vascular compartment, and the nurse must monitor the child for signs and symptoms of hypervolemia. Increased cardiac output results as fluids shift back to the vascular compartment. Hypertension is the result of hypervolemia.
