Nursing Elites

1. 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.

2. Which of the following statements about Helicobacter pylori (H. pylori) is false?

• A. H. pylori does not invade the gastric or duodenal epithelium
• B. H. pylori stimulates gastric acid secretion
• C. Eradication of H. pylori prevents adenocarcinoma of the stomach
• D. H. pylori produces a urease that splits urea into ammonia and CO2

Correct answer: C

Rationale: H. pylori is known to reside in the mucus layer of the stomach and does not invade the epithelium. It produces urease that splits urea into ammonia and CO2. This action helps in neutralizing the acidic environment and allows H. pylori to survive. Additionally, urease activity can be detected in diagnostic tests for H. pylori. The stimulation of gastric acid secretion and disruption of the protective mucus layer are mechanisms by which H. pylori promotes injury. While eradicating H. pylori infection has been associated with a decreased risk of developing gastric cancer, it does not prevent adenocarcinoma of the stomach entirely.

3. When working with a client who has chronic constipation, what should be included in client teaching to promote normal bowel function?

• A. Use glycerin suppositories on a regular basis
• B. Limit physical activity in order to promote bowel peristalsis
• C. Consume high-residue, high-fiber foods
• D. Resist the urge to defecate until the urge becomes intense

Correct answer: C

Rationale: Consuming high-residue, high-fiber foods is essential in promoting normal bowel function and preventing constipation. These foods help add bulk to the stool, making it easier to pass and preventing constipation. Glycerin suppositories may provide short-term relief but are not a long-term solution for chronic constipation. Physical activity actually helps promote bowel peristalsis, so limiting it would not be beneficial. Delaying defecation can lead to stool hardening and worsening constipation.

4. The healthcare provider is assessing a client with Raynaud's phenomenon. Which finding should the healthcare provider expect?

• A. Thickened and hardened skin.
• B. Painless ulcers on the fingertips.
• C. Episodes of cyanosis and pallor in the fingers.
• D. Red, scaly patches on the hands.

Correct answer: C

Rationale: Raynaud's phenomenon is characterized by vasospasm, leading to episodes of cyanosis (bluish discoloration) and pallor (pale color) in the fingers or toes, often triggered by cold temperatures or stress. This occurs due to the reduced blood flow during vasospastic episodes, causing the discoloration. Choices A, B, and D are incorrect findings associated with other conditions and are not typical of Raynaud's phenomenon.

5. 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.
