2. A patient has an acute upper GI hemorrhage. Your interventions include:
- A. Treating hypovolemia.
- B. Treating hypervolemia.
- C. Controlling the bleeding source.

3. 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.
4. A 40-year-old male client has been hospitalized with peptic ulcer disease. He is being treated with a histamine receptor antagonist (cimetidine), antacids, and diet. The nurse doing discharge planning will teach him that the action of cimetidine is to:
- A. Reduce gastric acid output
- B. Protect the ulcer surface
- C. Inhibit the production of hydrochloric acid (HCl)
- D. Inhibit vagus nerve stimulation
Correct answer: C
Rationale: Cimetidine inhibits the production of hydrochloric acid (HCl), which helps to treat peptic ulcer disease.
