1. A 70-year-old man presents with sudden onset of severe abdominal pain. He has a history of atrial fibrillation. Physical examination reveals a soft abdomen with minimal tenderness. What is the most likely diagnosis?

• A. Acute pancreatitis
• B. Mesenteric ischemia
• C. Peptic ulcer disease
• D. Diverticulitis

Correct answer: B

Rationale: The sudden onset of severe abdominal pain in a patient with atrial fibrillation, along with a soft abdomen and minimal tenderness on examination, suggest mesenteric ischemia due to embolic occlusion of the mesenteric arteries. This condition is characterized by a sudden and severe decrease in blood flow to the intestines, leading to abdominal pain and tenderness. Acute pancreatitis typically presents with epigastric pain that may radiate to the back, accompanied by elevated serum amylase and lipase levels. Peptic ulcer disease and diverticulitis usually do not manifest with the sudden onset of severe abdominal pain as described in the case.

2. A client with chronic obstructive pulmonary disease (COPD) is receiving oxygen therapy. Which intervention should the nurse implement to ensure the client's safety?

• A. Increase the oxygen flow rate to 6 liters/minute if the client is short of breath.
• B. Instruct the client to breathe deeply and cough frequently.
• C. Use a nasal cannula to deliver oxygen at a low flow rate.
• D. Encourage the client to remove the oxygen when eating or drinking.

Correct answer: C

Rationale: Using a nasal cannula to deliver oxygen at a low flow rate is the appropriate intervention for clients with COPD receiving oxygen therapy. High flow rates can lead to respiratory depression in COPD patients. This intervention helps maintain a safe and controlled oxygen delivery to prevent potential complications associated with high oxygen flow rates.

3. 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.

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. When teaching a client postoperative breathing techniques with an incentive spirometer (IS), what should the nurse encourage the client to do to maintain sustained maximal inspiration?

• A. Exhale forcefully into the tubing for 3 to 5 seconds.
• B. Inspire deeply and slowly over 3 to 5 seconds.
• C. Breathe into the spirometer using normal breath volumes.
• D. Perform IS breathing exercises every 6 hours.

Correct answer: B

Rationale: To maintain sustained maximal inspiration when using an incentive spirometer, the client should be encouraged to inspire deeply and slowly over 3 to 5 seconds. This technique aids in achieving the goal of sustained maximal inspiration, which is essential for postoperative respiratory recovery.
