Nursing Elites

1. A client with a new diagnosis of diabetes mellitus is learning to self-administer insulin. Which instruction should the nurse include?

• A. Store the insulin in the freezer.
• B. Administer the insulin at the same site each time.
• C. Rotate injection sites within the same region.
• D. Shake the vial vigorously before drawing up the insulin.

Correct answer: C

Rationale: The correct instruction for a client learning to self-administer insulin is to rotate injection sites within the same region. This practice helps prevent lipodystrophy, which is a condition characterized by fat tissue changes due to repeated injections in the same spot, and also ensures consistent absorption of insulin throughout the body. Storing insulin in the freezer is incorrect as it can lead to denaturation of the insulin. Administering the insulin at the same site each time can cause lipodystrophy and inconsistent absorption. Shaking the vial vigorously before drawing up the insulin is also incorrect as it can lead to insulin degradation.

2. A 68-year-old man with a history of diabetes, hypertension, and coronary artery disease (s/p coronary artery bypass graft two years ago) presents to the emergency room with fevers and left-sided abdominal pain. His physical examination reveals a temperature of 101.5°F, pulse 96, and blood pressure of 135/80. His abdomen is soft with moderate left lower quadrant tenderness. There is no rebound or guarding. Bowel sounds are present. A CT scan is done which reveals inflammation around an area of the left colon. The next step in his workup/management should be

• A. Antibiotic therapy with ciprofloxacin and metronidazole
• B. Referral for urgent colonoscopy
• C. Referral to a surgeon for immediate hemicolectomy
• D. Barium enema

Correct answer: A

Rationale: The patient's presentation is consistent with diverticulitis without evidence of perforation or abscess formation on CT scan. During acute infections, procedures like barium enema and colonoscopy should be avoided to prevent the risk of perforation. Urgent surgery is not indicated initially. The appropriate next step is to start antibiotic therapy aimed at gram-negative aerobes and anaerobes, such as ciprofloxacin and metronidazole, which are the initial treatment of choice for diverticulitis.

3. A client is on a mechanical ventilator. Which client response indicates that the neuromuscular blocker tubocurarine chloride (Tubarine) is effective?

• A. The client's extremities are paralyzed.
• B. The peripheral nerve stimulator causes twitching.
• C. The client clenches fist upon command.
• D. The client's Glasgow Coma Scale score is 14.

Correct answer: A

Rationale: The correct answer is A. Tubocurarine chloride is a neuromuscular blocker that works by causing paralysis of skeletal muscles. Therefore, if the client's extremities are paralyzed, it indicates that the medication is effective in achieving the desired muscle relaxation necessary for mechanical ventilation. Choices B and C are incorrect as they suggest muscle activity, which would not be expected with the administration of a neuromuscular blocker. Choice D is unrelated to the effectiveness of tubocurarine chloride.

4. A client with a history of atrial fibrillation is prescribed warfarin (Coumadin). Which laboratory test should the nurse monitor to determine the effectiveness of the medication?

• A. Platelet count.
• B. Prothrombin time (PT) and international normalized ratio (INR).
• C. Activated partial thromboplastin time (aPTT).
• D. Fibrinogen level.

Correct answer: B

Rationale: Prothrombin time (PT) and international normalized ratio (INR) are essential laboratory tests to monitor the effectiveness of warfarin (Coumadin) therapy. These tests help assess the clotting time and the desired anticoagulant effect of the medication. Monitoring PT and INR levels is crucial to ensure that the client is within the therapeutic range, reducing the risk of bleeding or clotting complications associated with warfarin therapy. Platelet count (Choice A) measures the number of platelets in the blood and is not specific for monitoring warfarin therapy. Activated partial thromboplastin time (aPTT) (Choice C) is more commonly used to monitor heparin therapy, not warfarin. Fibrinogen level (Choice D) assesses the amount of fibrinogen in the blood and is not a specific test for monitoring warfarin therapy.

5. The client has a nasogastric (NG) tube and is receiving enteral feedings. What intervention should the nurse implement to prevent complications associated with the NG tube?

• A. Flush the NG tube with water before and after feedings.
• B. Check gastric residual volume every 6 hours.
• C. Keep the head of the bed elevated at 30 degrees.
• D. Replace the NG tube every 24 hours.

Correct answer: C

Rationale: Keeping the head of the bed elevated at 30 degrees is crucial in preventing aspiration, a common complication associated with nasogastric (NG) tubes and enteral feedings. This position helps reduce the risk of reflux and aspiration of gastric contents into the lungs, promoting client safety and preventing respiratory complications. Flushing the NG tube with water before and after feedings (Choice A) is not the primary intervention to prevent complications. Checking gastric residual volume every 6 hours (Choice B) is important but not directly related to preventing complications associated with the NG tube. Replacing the NG tube every 24 hours (Choice D) is not a standard practice and is not necessary to prevent complications if the tube is functioning properly.
