ATI RN Exit Exam Test Bank

Correct Answer: B

Rationale: In the scenario of early decelerations noted during labor with electronic fetal monitoring, the nurse should expect head compression. Early decelerations are a normal response to fetal head compression during contractions and are not indicative of fetal distress. Choice A, fetal hypoxia, is incorrect as early decelerations are not associated with fetal oxygen deprivation. Choices C and D, placenta previa and umbilical cord prolapse, are unrelated to the scenario described and do not cause early decelerations.

Correct Answer: B

Rationale: Flat T waves are a characteristic ECG finding in hypokalemia. Hypokalemia causes a decrease in serum potassium levels, leading to altered cardiac conduction. Flat T waves are associated with hypokalemia-induced cardiac dysrhythmias. Elevated ST segments are typically seen in conditions like myocardial infarction, not in hypokalemia. Bradycardia is not a typical manifestation of hypokalemia; instead, tachycardia may occur due to potassium imbalances affecting the heart's electrical activity.

Correct Answer: A

Rationale: The correct answer is A. A heart rate of 58/min is indicative of bradycardia, a potential sign of digoxin toxicity, which should be reported immediately. While weight gain, respiratory rate, and temperature are important parameters to monitor, they are not as critical as identifying bradycardia in a client taking digoxin.

Correct Answer: D

Rationale: The correct answer is D: Apply sequential compression devices to the client's legs. Sequential compression devices help prevent venous stasis and reduce the risk of DVT by promoting blood flow in the legs. Massaging the client's legs every 2 hours (choice A) may dislodge a clot if present, leading to a higher risk of embolism. Instructing the client to sit with the legs crossed (choice B) can impede blood flow and increase the risk of DVT. Administering prophylactic antibiotics (choice C) is not indicated for preventing DVT, as antibiotics are used to treat infections caused by bacteria, not to prevent blood clots.

Correct Answer: C

Rationale: Checking the client's blood glucose level every 4 hours is essential when managing a client on TPN to monitor for hyperglycemia, a common complication. Monitoring urine output (Choice A) is important but not a priority in this scenario. Administering a bolus of 0.9% sodium chloride (Choice B) is not indicated as it is unrelated to managing TPN. Flushing the TPN line with sterile water (Choice D) is necessary, but it should be done with 0.9% sodium chloride, not water.
