Nursing Elites

1. A patient with hypertension is prescribed lisinopril. What side effect should the nurse monitor for?

• A. Hyperkalemia
• B. Hypoglycemia
• C. Bradycardia
• D. Constipation

Correct answer: A

Rationale: When a patient is prescribed lisinopril, an ACE inhibitor, the nurse should monitor for hyperkalemia. Lisinopril can cause hyperkalemia by decreasing aldosterone secretion, which leads to potassium retention in the body. Hyperkalemia is a potential side effect of ACE inhibitors and should be closely monitored, as it can have serious consequences such as affecting cardiac function.

2. A 28-year-old woman presents with abdominal pain, diarrhea, and rectal bleeding. She has a history of similar episodes in the past. What is the most likely diagnosis?

• A. Ulcerative colitis
• B. Irritable bowel syndrome
• C. Celiac disease
• D. Diverticulitis

Correct answer: A

Rationale: The constellation of symptoms including abdominal pain, diarrhea, and rectal bleeding in a young woman with a history of similar episodes is highly suggestive of ulcerative colitis. This chronic inflammatory condition primarily affects the colon and rectum, leading to symptoms such as bloody diarrhea, abdominal pain, and urgency. The recurrent nature of her symptoms and the presence of rectal bleeding further support this diagnosis over other conditions listed, such as irritable bowel syndrome, celiac disease, or diverticulitis, which typically do not present with the same combination of symptoms and history.

3. A 36-year-old woman complains of reflux symptoms and intermittent diarrhea. The diagnosis of gastrinoma is suspected so a fasting serum gastrin is obtained and found to be 280 pg/mL (normal <115 pg/mL). An abdominal CT is negative. What would you do now?

• A. Refer her for an exploratory laparotomy
• B. Measure serum gastrin in response to secretin infusion
• C. Treat her for H. pylori
• D. Obtain a dedicated small bowel series

Correct answer: B

Rationale: The next step after finding an elevated fasting serum gastrin level is to perform a secretin stimulation test. This test helps differentiate between gastrinoma and other causes of elevated gastrin levels, such as proton-pump inhibitor therapy or H2 antagonists. In gastrinoma, the serum gastrin level should further increase after secretin infusion, while in other conditions, the levels would not significantly rise. Exploratory laparotomy would be premature without confirming the diagnosis. Treating for H. pylori is not indicated as the diagnosis of gastrinoma is under consideration and not Helicobacter pylori infection. A dedicated small bowel series is not the next appropriate step in this scenario.

4. A 70-year-old woman presents with fatigue, anorexia, and weight loss. She has noticed darkening of her skin, particularly in sun-exposed areas. Laboratory tests reveal hyponatremia, hyperkalemia, and low cortisol levels. What is the most likely diagnosis?

• A. Cushing's syndrome
• B. Addison's disease
• C. Hypothyroidism
• D. Pheochromocytoma

Correct answer: B

Rationale: The combination of symptoms such as fatigue, anorexia, weight loss, hyperpigmentation of the skin, along with hyponatremia, hyperkalemia, and low cortisol levels, points towards Addison's disease. This condition is characterized by adrenal insufficiency, leading to a deficiency in cortisol and aldosterone production.

5. A 56-year-old woman presents to discuss the results of her recent upper endoscopy. She was having some mild abdominal pain, so she underwent the procedure, which revealed an ulcer in the antrum of the stomach. Biopsy of the lesion revealed the presence of H. pylori. All of the following statements regarding her condition are correct except

• A. H. pylori has been associated with gastric MALT (mucosa-associated lymphoid tissue)
• B. Reinfection is rare despite adequate treatment
• C. Triple drug therapy has been shown to be more effective than dual drug therapy
• D. If her H. pylori IgG antibody titer was elevated prior to therapy, it can be used to monitor treatment efficacy

Correct answer: B

Rationale: H. pylori is associated with a majority of peptic ulcer disease cases and has links to gastric MALT and adenocarcinoma. Triple drug therapy is more effective than dual therapy. Reinfection after adequate treatment is rare. While urea breath testing is a better diagnostic tool, quantitative serology can monitor treatment efficacy. A 30% decrease in IgG titer should occur post-therapy, indicating effectiveness.
