1. A 40-year-old woman presents with fatigue, polyuria, and polydipsia. Laboratory tests reveal hyperglycemia and ketonuria. What is the most likely diagnosis?

• A. Type 1 diabetes mellitus
• B. Type 2 diabetes mellitus
• C. Diabetes insipidus
• D. Hyperthyroidism

Correct answer: A

Rationale: The combination of symptoms including fatigue, polyuria, polydipsia, along with laboratory findings of hyperglycemia and ketonuria strongly suggest type 1 diabetes mellitus. In type 1 diabetes mellitus, there is a deficiency of insulin leading to high blood sugar levels (hyperglycemia) and the breakdown of fats producing ketones, causing ketonuria. Type 2 diabetes mellitus typically presents differently and is more common in older individuals. Diabetes insipidus is characterized by excessive thirst and urination due to a deficiency of antidiuretic hormone, distinct from the provided clinical scenario. Hyperthyroidism may present with some overlapping symptoms like fatigue, but it does not account for the specific laboratory findings of hyperglycemia and ketonuria seen in this case.

2. A patient with chronic obstructive pulmonary disease (COPD) is prescribed ipratropium. What is the primary action of this medication?

• A. Reduce inflammation
• B. Relieve bronchospasm
• C. Suppress cough
• D. Thin respiratory secretions

Correct answer: B

Rationale: Ipratropium is an anticholinergic bronchodilator that primarily works to relieve bronchospasm by dilating the airways and improving airflow in patients with COPD. It does not have a significant effect on reducing inflammation, suppressing cough, or thinning respiratory secretions.

3. Which of the following statements is true about ischemic colitis?

• A. Typically requires colonic resection
• B. Affects the watershed areas of the colon, namely, the splenic flexure, right colon, and rectum
• C. Is only seen in the elderly
• D. Requires colonoscopic intervention

Correct answer: B

Rationale: Ischemic colitis most often results from low-flow states associated with hypotension or poor perfusion. As a result, the vascular watershed areas of the colon, including the splenic flexure, right colon, and rectum, are at highest risk of ischemic injury. Therefore, option B is correct as it accurately identifies the areas commonly affected by ischemic colitis.

4. 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.

5. A patient with chronic kidney disease (CKD) is prescribed calcium acetate. What is the primary purpose of this medication?

• A. Treat hyperkalemia
• B. Reduce phosphate levels
• C. Lower blood pressure
• D. Increase hemoglobin levels

Correct answer: B

Rationale: The primary purpose of prescribing calcium acetate to a patient with chronic kidney disease (CKD) is to reduce phosphate levels. Calcium acetate binds to dietary phosphate, preventing its absorption and helping to manage hyperphosphatemia commonly seen in CKD patients.
