Nursing Elites

1. A patient with atrial fibrillation is prescribed warfarin. Which laboratory test should the nurse monitor to assess the effectiveness of the medication?

• A. Complete blood count (CBC)
• B. Prothrombin time (PT)/INR
• C. Partial thromboplastin time (PTT)
• D. Serum potassium level

Correct answer: B

Rationale: The correct answer is B: Prothrombin time (PT)/INR. Warfarin affects the clotting ability of the blood by inhibiting vitamin K-dependent clotting factors. Monitoring the prothrombin time (PT) and international normalized ratio (INR) is crucial to assess the effectiveness and safety of warfarin therapy. These tests help determine if the patient is within the desired anticoagulation range to prevent either clotting issues or excessive bleeding.

2. When covering another nurse's assignment during a lunch break, based on the status report provided, which client should the charge nurse check first?

• A. The client admitted yesterday with diabetic ketoacidosis whose blood glucose level is now 195 mg/dl.
• B. The client with an ileal conduit created two days ago with a scant amount of blood in the drainage pouch.
• C. The client post-triple coronary bypass four days ago who has serosanguinous drainage in the chest tube.
• D. The client with a pneumothorax secondary to a gunshot wound with a current pulse oximeter reading of 90%.

Correct answer: D

Rationale: The client with a pneumothorax and a pulse oximeter reading of 90% indicates potential respiratory compromise, requiring immediate attention to prevent further deterioration.

3. A client with type 1 diabetes mellitus is experiencing nausea and vomiting. What advice should the nurse give regarding insulin administration?

• A. Skip your insulin dose until you can eat.
• B. Take your insulin as prescribed, but monitor your blood glucose closely.
• C. Reduce your insulin dose by half.
• D. Only take your long-acting insulin.

Correct answer: B

Rationale: The correct advice for a client with type 1 diabetes mellitus experiencing nausea and vomiting is to take insulin as prescribed but monitor blood glucose closely. It is essential to continue insulin therapy even if not eating normally to prevent complications from high blood sugar levels. Skipping insulin doses can lead to dangerous fluctuations in blood glucose levels. Reducing the insulin dose without proper guidance can also result in uncontrolled blood sugar. Taking only long-acting insulin may not provide adequate coverage for mealtime blood sugar elevation. Therefore, the best course of action is to take prescribed insulin doses while closely monitoring blood glucose levels.

4. A patient with peptic ulcer disease is prescribed omeprazole. When should the patient take this medication for optimal effectiveness?

• A. With meals
• B. At bedtime
• C. Before meals
• D. After meals

Correct answer: C

Rationale: Omeprazole should be taken before meals to reduce stomach acid production and promote healing of the ulcer. Taking it before meals ensures that the medication can inhibit acid secretion when the stomach is most active in producing acid, thereby maximizing its effectiveness in treating peptic ulcer disease.

5. The client with gastroesophageal reflux disease (GERD) is being taught about dietary modifications by the nurse. Which instruction should the nurse include?

• A. Increase your intake of spicy foods.
• B. Avoid lying down immediately after eating.
• C. Consume a high-fat diet.
• D. Drink caffeinated beverages with meals.

Correct answer: B

Rationale: Avoiding lying down immediately after eating is essential in managing GERD as it helps prevent reflux symptoms by allowing gravity to assist in keeping stomach contents down. Lying down can worsen symptoms by allowing acid to flow back into the esophagus.
