Correct Answer: D

Rationale: Corrected Rationale: Early decelerations are caused by head compression resulting from the fetal head being compressed during contractions. They are considered benign and do not indicate fetal distress. Choice A, fetal hypoxia, is incorrect because early decelerations are not associated with fetal hypoxia. Choice B, abruptio placentae, is incorrect as it is a condition where the placenta prematurely separates from the uterine wall. Choice C, post maturity, is incorrect as it refers to a fetus that remains in the uterus past the due date.

Correct Answer: A

Rationale: The correct answer is A: Hypokalemia. Furosemide, a loop diuretic, commonly causes the loss of potassium in the urine, leading to hypokalemia. This electrolyte imbalance can result in various complications such as cardiac arrhythmias and muscle weakness. Choice B, Hyponatremia, is not typically associated with furosemide use. Choice C, Hyperkalemia, is the opposite of the expected electrolyte imbalance caused by furosemide. Choice D, Hypercalcemia, is not a common side effect of furosemide.

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: A

Rationale: The correct answer is to monitor vital signs. Post-operative patients need close monitoring of their vital signs to detect early signs of complications such as changes in blood pressure, heart rate, temperature, and respiratory rate. While monitoring the surgical site is also important for signs of infection, assessing vital signs takes precedence as it provides immediate information about the patient's overall condition. Checking blood glucose levels may be essential for specific patients but is not the primary assessment for monitoring post-op complications. Checking for abnormal breath sounds is important but falls secondary to monitoring vital signs as it indicates respiratory issues rather than providing a comprehensive assessment of the patient's condition.

Correct Answer: D

Rationale: The correct answer is D: 'Trim toenails straight across.' In clients with diabetes, trimming toenails straight across is important to prevent ingrown toenails, reducing the risk of infections. Soaking feet in warm water daily (choice A) can lead to dry skin and potentially cause skin breakdown in diabetic clients. While wearing cotton socks (choice B) is beneficial for good foot hygiene, it is not as crucial as trimming toenails correctly. Applying lotion to feet after bathing (choice C) is helpful for moisturizing the skin, but the emphasis should be on nail care to prevent complications like ingrown toenails.
