1. 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.

2. A 65-year-old man presents with weight loss, jaundice, and a palpable mass in the right upper quadrant. Laboratory tests reveal elevated bilirubin and alkaline phosphatase levels. What is the most likely diagnosis?

• A. Gallstones
• B. Hepatitis
• C. Pancreatic cancer
• D. Primary biliary cirrhosis

Correct answer: C

Rationale: The combination of weight loss, jaundice, a palpable mass in the right upper quadrant, and elevated bilirubin and alkaline phosphatase levels strongly suggests pancreatic cancer. The presentation is classic for pancreatic malignancy, which commonly presents with obstructive jaundice due to the tumor blocking the common bile duct, leading to elevated bilirubin and alkaline phosphatase levels. Weight loss is a common symptom of advanced pancreatic cancer. The palpable mass in the right upper quadrant corresponds to the location of the pancreas. Gallstones typically manifest with different symptoms, while hepatitis and primary biliary cirrhosis are less likely to present with a palpable mass and weight loss in this scenario.

3. Why is a low-protein diet recommended for a client with hepatic encephalopathy?

• A. Hyperglycemia
• B. Hypoglycemia
• C. Increased ammonia levels
• D. Electrolyte imbalance

Correct answer: C

Rationale: A low-protein diet is recommended for clients with hepatic encephalopathy to reduce ammonia levels. Ammonia, a byproduct of protein metabolism, can accumulate in the blood due to impaired liver function. Elevated ammonia levels can lead to worsening hepatic encephalopathy, a condition characterized by cognitive and neurological disturbances. Therefore, by limiting protein intake, the production of ammonia is reduced, thereby helping to manage hepatic encephalopathy. Choices A, B, and D are incorrect because hepatic encephalopathy is not primarily related to hyperglycemia, hypoglycemia, or electrolyte imbalance. The focus is on reducing ammonia levels to improve the condition.

4. 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.

5. A client's health history is suggestive of inflammatory bowel disease. Which of the following would suggest Crohn disease, rather than ulcerative colitis, as the cause of the client's signs and symptoms?

• A. A pattern of distinct exacerbations and remissions
• B. Severe diarrhea
• C. An absence of blood in stool
• D. Involvement of the rectal mucosa

Correct answer: C

Rationale: In the context of inflammatory bowel disease, the absence of blood in stool is more indicative of Crohn disease. Crohn disease typically presents with non-bloody stools, while ulcerative colitis often involves bloody stools due to continuous mucosal inflammation confined to the colon and rectum.
