Nursing Elites

1. Prior to elective surgery, a patient taking warfarin should receive which instruction regarding warfarin therapy?

• A. Continue taking warfarin until the day of surgery.
• B. Stop taking warfarin three days before surgery.
• C. Switch to aspirin before surgery.
• D. Stop taking warfarin one week before surgery.

Correct answer: D

Rationale: Prior to elective surgery, a patient taking warfarin should be instructed to stop taking warfarin around one week before the procedure. This timeframe allows for the effects of warfarin to diminish, lowering the risk of excessive bleeding during surgery. Continuing warfarin until the day of surgery (Choice A) increases the risk of bleeding complications. Stopping warfarin three days before surgery (Choice B) may not provide enough time for the anticoagulant effects to subside. Switching to aspirin before surgery (Choice C) is not recommended as a substitute for warfarin in this context.

2. A client with type 1 diabetes mellitus is admitted with hyperglycemia. Which laboratory result requires the most immediate intervention?

• A. Serum glucose of 350 mg/dL.
• B. Serum potassium of 2.8 mEq/L.
• C. Serum sodium of 136 mEq/L.
• D. Serum bicarbonate of 20 mEq/L.

Correct answer: B

Rationale: A serum potassium level of 2.8 mEq/L is critically low and can cause cardiac arrhythmias, requiring immediate intervention. Hypokalemia is a life-threatening condition that needs prompt correction to prevent serious complications. High serum glucose levels (choice A) are a concern in diabetes but do not pose an immediate life-threatening risk compared to severe hypokalemia. Serum sodium (choice C) and serum bicarbonate levels (choice D) are within normal ranges and do not require immediate intervention.

3. The client with bacterial pneumonia is receiving intravenous antibiotics. Which assessment finding indicates that the treatment is effective?

• A. Increased respiratory rate.
• B. Decreased oxygen saturation.
• C. Clear lung sounds.
• D. Elevated white blood cell count.

Correct answer: C

Rationale: Clear lung sounds indicate that the antibiotics are effectively treating the bacterial pneumonia by resolving the infection and reducing the inflammation in the lungs, leading to improved air exchange and ventilation. Increased respiratory rate (Choice A) and decreased oxygen saturation (Choice B) are indicative of ongoing respiratory distress and ineffective treatment. Elevated white blood cell count (Choice D) suggests a persistent infection rather than effective treatment.

4. An older adult with a diagnosis of Alzheimer's disease has been experiencing fecal incontinence, with no recent change in stool character noted by the nurse. What is the nurse's most appropriate intervention?

• A. Keep a food diary to identify foods that worsen the client's symptoms
• B. Provide the client with a bland, low-residue diet
• C. Toilet the client on a frequent, scheduled basis
• D. Collaborate with the primary provider to secure an order for loperamide

Correct answer: C

Rationale: The most appropriate intervention for an older adult with Alzheimer's disease experiencing fecal incontinence and no change in stool character is to toilet the client on a frequent, scheduled basis. Scheduled toileting can help manage incontinence by establishing a routine for bowel movements, which may aid in reducing episodes of fecal incontinence.

5. A 45-year-old man with a history of chronic heartburn presents with progressive difficulty swallowing solids and liquids. He has lost 10 pounds in the past two months. What is the most likely diagnosis?

• A. Esophageal stricture
• B. Esophageal cancer
• C. Achalasia
• D. Peptic ulcer disease

Correct answer: B

Rationale: In this scenario, the patient's presentation of progressive dysphagia to both solids and liquids, along with significant weight loss, is concerning for esophageal cancer. The history of chronic heartburn further raises suspicion as chronic gastroesophageal reflux disease is a risk factor for the development of esophageal adenocarcinoma. Esophageal stricture could cause dysphagia but is less likely to be associated with significant weight loss. Achalasia typically presents with dysphagia to solids more than liquids and does not commonly cause weight loss. Peptic ulcer disease is less likely to lead to progressive dysphagia and significant weight loss compared to esophageal cancer.
