Nursing Elites

1. A 30-year-old woman is admitted to the hospital with complaints of severe abdominal cramping and diarrhea. The nurse evaluates the effectiveness of the patient's intravenous therapy. Which of the following laboratory tests BEST reflects hydration status?

• A. Erythrocyte sedimentation rate.
• B. White blood cell count.
• C. Hematocrit.
• D. Serum glucose.

Correct answer: C

Rationale: Hematocrit is the best indicator of hydration status because it reflects the proportion of red blood cells in the blood. An increased hematocrit indicates dehydration, as the blood becomes more concentrated due to fluid loss. Erythrocyte sedimentation rate (Choice A) is a nonspecific marker of inflammation, not hydration status. White blood cell count (Choice B) is an indicator of infection or inflammation. Serum glucose (Choice D) is used to monitor blood sugar levels, not hydration status.

2. A client with a peptic ulcer is scheduled for a vagotomy. The client asks the nurse about the purpose of this procedure. The nurse tells the client that the procedure:

• A. Decreases food absorption in the stomach
• B. Heals the gastric mucosa
• C. Halts stress reactions
• D. Reduces the stimulus to acid secretions

Correct answer: D

Rationale: A vagotomy reduces the stimulus to acid secretions by cutting the vagus nerve, which innervates the stomach.

3. Sitty, a 66 y.o. patient underwent a colostomy for ruptured diverticulum. She did well during the surgery and returned to your med-surg floor in stable condition. You assess her colostomy 2 days after surgery. Which finding do you report to the doctor?

• A. Blanched stoma
• B. Edematous stoma
• C. Reddish-pink stoma
• D. Brownish-black stoma

Correct answer: A

Rationale: A blanched stoma 2 days after colostomy surgery should be reported to the doctor as it may indicate compromised blood flow.

4. The nurse assesses the client's understanding of the relationship between body position and gastroesophageal reflux. Which response would indicate that the client understands measures to avoid problems with reflux while sleeping?

• A. I can elevate the foot of the bed 4 to 6 inches.
• B. I can sleep on my stomach with my head turned to the left.
• C. I can sleep on my back without a pillow under my head.
• D. I can elevate the head of the bed 4 to 6 inches.

Correct answer: D

Rationale: Sleeping with the head of the bed elevated encourages movement of food through the esophagus by gravity. By fostering esophageal acid clearance, gravity helps keep the acidic pepsin and alkaline biliary secretions from contacting the esophagus. Elevating the foot of the bed does not affect clearance of esophageal acid. Sleeping on the stomach with the head turned to the left will not decrease reflux incidence. Sleeping flat without a pillow under the head does not enhance clearance.

5. A client with suspected gastric cancer undergoes an endoscopy of the stomach. Which of the following assessments made after the procedure would indicate the development of a potential complication?

• A. The client complains of a sore throat
• B. The client displays signs of sedation
• C. The client experiences a sudden increase in temperature
• D. The client demonstrates a lack of appetite

Correct answer: C

Rationale: A sudden increase in temperature after an endoscopy can indicate a potential complication, such as perforation.
