Nursing Elites

1. A client with type 1 diabetes mellitus is admitted to the emergency department with confusion, sweating, and a blood sugar level of 45 mg/dL. What is the nurse's priority action?

• A. Administer 50% dextrose IV push
• B. Provide a carbohydrate snack
• C. Check the client's urine for ketones
• D. Start an insulin drip

Correct answer: A

Rationale: A blood sugar level of 45 mg/dL indicates severe hypoglycemia, which can lead to life-threatening complications if not treated immediately. The priority is to administer IV dextrose to rapidly increase the blood sugar level. Administering 50% dextrose IV push will provide a quick source of glucose to raise the blood sugar. Providing a carbohydrate snack is not the immediate priority in this critical situation. Checking the client's urine for ketones is important in diabetic ketoacidosis, not for hypoglycemia. Starting an insulin drip would further lower the blood sugar and worsen the client's condition.

2. A client with a history of deep vein thrombosis (DVT) is prescribed warfarin. Which laboratory value should the nurse monitor to assess the therapeutic effect of this medication?

• A. Platelet count
• B. Prothrombin time (PT)
• C. White blood cell count
• D. Hemoglobin level

Correct answer: B

Rationale: Prothrombin time (PT) is the correct laboratory value to monitor to assess the therapeutic effect of warfarin. Warfarin works by inhibiting clotting factors, and PT measures the time it takes for blood to clot. Monitoring PT helps ensure that the medication is working effectively to prevent clot formation without causing excessive bleeding. Platelet count (Choice A) is not specific to warfarin therapy and assesses the number of platelets in the blood. White blood cell count (Choice C) and hemoglobin level (Choice D) are not directly related to monitoring the therapeutic effect of warfarin.

3. The nurse is providing care for a client with severe peripheral arterial disease (PAD). The client reports a history of rest ischemia, with leg pain that occurs during the night. Which action should the nurse take in response to this finding?

• A. Elevate the legs on pillows
• B. Encourage ambulation and leg exercises
• C. Provide a heating pad for warmth
• D. Offer cold packs when the pain occurs

Correct answer: C

Rationale: Providing warmth can help dilate peripheral vessels and increase blood flow, relieving ischemic pain. In PAD, where there is already compromised blood flow, elevating the legs or applying cold therapy could worsen ischemic pain by further reducing blood flow to the extremities. Encouraging ambulation and leg exercises may be beneficial in other conditions but not suitable for clients with severe PAD experiencing rest ischemia.

4. What pathophysiological events occur sequentially in the development of atherosclerosis?

• A. Foam cells release growth factors.
• B. Smooth muscle grows over fatty streaks creating fibrous plaques.
• C. Macrophages consume low-density lipoprotein (LDL) and create foam cells.
• D. Arterial endothelium injury causes inflammation.

Correct answer: D

Rationale: The correct sequence of pathophysiological events in the development of atherosclerosis starts with arterial endothelium injury causing inflammation. This inflammation triggers the formation of foam cells by macrophages consuming low-density lipoprotein (LDL). Subsequently, smooth muscle grows over fatty streaks, creating fibrous plaques. Therefore, option D is the correct answer. Choices A, B, and C are incorrect because they do not reflect the accurate chronological order of events in the pathogenesis of atherosclerosis.

5. A client with a chest tube following a pneumothorax is complaining of increased shortness of breath. What is the nurse's first action?

• A. Check for kinks in the chest tube tubing.
• B. Assess the client's lung sounds.
• C. Elevate the head of the bed to 30 degrees.
• D. Prepare for chest tube replacement.

Correct answer: C

Rationale: The correct first action for a client with a chest tube experiencing increased shortness of breath is to elevate the head of the bed to 30 degrees. This position promotes lung expansion, improves oxygenation, and can help relieve shortness of breath. Checking for kinks in the chest tube tubing would be important but not the first action in this situation. Assessing the client's lung sounds is also important but not the initial priority. Preparing for chest tube replacement is not indicated based solely on the client's complaint of increased shortness of breath.
