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 client with chronic kidney disease is prescribed a low-protein diet. Which laboratory result should the nurse monitor to evaluate the effectiveness of the diet?

• A. Blood urea nitrogen (BUN)
• B. Serum potassium
• C. Serum calcium
• D. Creatinine clearance

Correct answer: A

Rationale: Blood urea nitrogen (BUN) levels should be monitored to assess the effectiveness of a low-protein diet in clients with chronic kidney disease. BUN levels reflect the breakdown of protein in the body, and a low-protein diet aims to reduce BUN levels to lessen the workload on the kidneys. Therefore, monitoring BUN levels is crucial in managing kidney function and evaluating the impact of dietary modifications. Serum potassium, serum calcium, and creatinine clearance are important parameters to monitor in clients with chronic kidney disease, but they are not specifically indicative of the effectiveness of a low-protein diet. Serum potassium levels are crucial in assessing electrolyte balance, serum calcium levels are important for bone health and nerve function, and creatinine clearance reflects kidney function overall, not just the impact of a low-protein diet.

3. In acute pancreatitis, a client experiencing severe abdominal pain should have which enzyme level closely monitored?

• A. Serum amylase.
• B. Serum sodium.
• C. Serum calcium.
• D. Serum potassium.

Correct answer: A

Rationale: In acute pancreatitis, serum amylase levels should be closely monitored. Elevated serum amylase levels are a key diagnostic marker for acute pancreatitis, aiding in the assessment and management of the patient's condition. Monitoring serum sodium, calcium, or potassium levels is not typically associated with acute pancreatitis and would not provide relevant information for this specific condition.

4. What physical assessment data should the nurse consider a normal finding for a primigravida client who is 12 hours postpartum?

• A. Soft, spongy fundus.
• B. Saturating two perineal pads per hour.
• C. Pulse rate of 56 BPM.
• D. Unilateral lower leg pain.

Correct answer: C

Rationale: The correct answer is C. A pulse rate of 56 BPM can be considered a normal finding for a primigravida client who is 12 hours postpartum. Postpartum bradycardia can occur due to increased stroke volume and decreased vascular resistance after delivery. It is important for the nurse to monitor the client's vital signs and recognize that a lower pulse rate can be expected in the immediate postpartum period. Choices A, B, and D are incorrect because a soft, spongy fundus may indicate uterine atony, saturating two perineal pads per hour is excessive bleeding, and unilateral lower leg pain could suggest deep vein thrombosis, all of which would require further assessment and intervention.

5. 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.
