Correct Answer: D

Rationale: The correct action for the nurse to take is to administer the Coumadin along with the heparin drip as ordered. Heparin and warfarin are often given together initially because warfarin takes a few days to become effective. Discontinuing the heparin drip prior to initiating Coumadin could leave the patient without anticoagulation coverage during the period when warfarin's effects are not yet established. Checking the client's INR prior to beginning Coumadin is important but not the immediate action to take when both medications are ordered together. Clarifying the order with the health care provider is unnecessary in this scenario as it is common practice to give heparin and warfarin concurrently in the transition period.

Correct Answer: C

Rationale: The correct intervention for a client with an ileal conduit is to report to the healthcare provider any decrease in urinary output. A decrease in urinary output can be indicative of a blockage or other complication, necessitating immediate attention. Choice A is incorrect because pouching the stoma with a margin around it is not directly related to managing complications. Choice B is incorrect as referring the client to an ostomy association may be beneficial for education but is not the immediate action needed for decreased urinary output. Choice D is incorrect because monitoring for infection, although important, is not the priority when dealing with a potential complication like decreased urinary output.

Correct Answer: C

Rationale: Ambulance exchange points are set up when threats to air resources make it impossible to evacuate by air from forward units. These points serve as locations where patients can be transferred from ambulances to aircraft for further evacuation. Area support medical battalions (Choice A) are not directly related to this scenario, as they provide medical support to larger areas. TOE units (Choice B) refer to tables of organization and equipment, not specific to this situation. Field hospitals (Choice D) are more permanent facilities for treating patients and are not specifically for transferring patients under threats to air resources.

Correct Answer: D

Rationale: The correct answer is D, Erythropoietin deficiency anemia. Chronic kidney disease often leads to anemia due to decreased production of erythropoietin. This hormone, produced by the kidneys, stimulates the bone marrow to produce red blood cells. Choices A, B, and C are incorrect. Iron-deficiency anemia is characterized by low iron levels, vitamin B12 deficiency anemia by inadequate vitamin B12, and aplastic anemia by bone marrow failure.

Correct Answer: B

Rationale: An apical rate of 140 bpm is within the normal range for a newborn. Digoxin is commonly used to treat heart failure by increasing the strength and efficiency of the heart's contractions. Since the heart rate is within the normal range, there is no need to hold the medication or notify the healthcare provider. Rechecking the apical rate in an hour is unnecessary as the heart rate is not alarming. Therefore, the appropriate nursing action is to administer the digoxin.
