Correct Answer: B

Rationale: When caring for a patient with a central line, monitoring for infection is crucial. This is because central lines can introduce bacteria into the bloodstream, leading to serious infections. While flushing the line daily and changing the dressing weekly are important aspects of central line care, monitoring for infection takes precedence. Infections can occur rapidly and have severe consequences, so early detection through vigilant monitoring is key. Replacing the central line every week is not a standard practice and should only be done when clinically indicated, such as in cases of infection or malfunction.

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 to monitor the patient's respiratory rate. This assessment is essential as it ensures that the patient is breathing adequately post-surgery. Maintaining a patent airway and adequate oxygenation are the top priorities in the immediate postoperative period. Monitoring blood pressure, checking the surgical site, or monitoring heart rate are important assessments but are not the priority immediately upon the patient's return from surgery.

Correct Answer: B

Rationale: The correct answer is B: "Exercise for 30 minutes at least 5 days a week." Regular exercise helps promote cardiovascular health and manage hypertension. Choice A is incorrect because increasing sodium intake is not recommended for hypertension. Choice C is incorrect because while sleep is important, excessive sleep duration is not typically part of hypertension management. Choice D is incorrect because fluid intake should be adequate unless advised otherwise by a healthcare provider.

Correct Answer: A

Rationale: The most appropriate action when a patient is experiencing severe dehydration is to administer IV fluids. This intervention is crucial in rapidly correcting dehydration and restoring fluid balance. Encouraging oral fluids may not be sufficient in cases of severe dehydration where intravenous rehydration is needed. Monitoring electrolytes is important but administering fluids takes precedence in severe dehydration. Performing a neurological exam is not the primary intervention for severe dehydration.
