1. A client with cirrhosis is at risk for bleeding. Which laboratory test is most important to monitor?
- A. Blood glucose
- B. Serum creatinine
- C. Prothrombin time (PT)
- D. Electrolytes
Correct answer: C
Rationale: In clients with cirrhosis, monitoring the Prothrombin time (PT) is crucial as it assesses the blood's ability to clot. Cirrhosis can lead to impaired liver function, affecting the synthesis of clotting factors, hence increasing the risk of bleeding. Maintaining a close watch on PT levels helps in timely intervention to prevent excessive bleeding episodes. Blood glucose (Choice A) is not directly related to the clotting function; serum creatinine (Choice B) and electrolytes (Choice D) are important, but in cirrhosis, monitoring PT takes precedence due to the increased bleeding risk.
2. 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.
3. 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.
4. A client with rheumatoid arthritis is prescribed methotrexate. Which instruction should the nurse include in the client's teaching?
- A. Avoid alcohol while taking this medication.
- B. Take the medication with a full meal.
- C. Increase your intake of high-fiber foods.
- D. Avoid exposure to sunlight.
Correct answer: A
Rationale: The correct instruction for the client prescribed with methotrexate is to avoid alcohol while taking this medication. Methotrexate can cause liver toxicity, and alcohol consumption can further exacerbate this risk. It is crucial for patients to abstain from alcohol to prevent adverse effects on the liver. Therefore, instructing the client to avoid alcohol is a key component of safe medication use and management of rheumatoid arthritis.
5. What action should the nurse take for a patient admitted with diabetic ketoacidosis exhibiting rapid, deep respirations?
- A. Administer the prescribed PRN lorazepam (Ativan).
- B. Start the prescribed PRN oxygen at 2 to 4 L/min.
- C. Administer the prescribed normal saline bolus and insulin.
- D. Encourage the patient to practice guided imagery for relaxation.
Correct answer: C
Rationale: The correct action for a patient with diabetic ketoacidosis and rapid, deep (Kussmaul) respirations is to administer a normal saline bolus and insulin. The rapid, deep respirations indicate a metabolic acidosis, which requires correction with a saline bolus to prevent hypovolemia and insulin to facilitate glucose re-entry into cells. Oxygen therapy is not necessary since the increased respiratory rate is compensatory and not due to hypoxemia. Encouraging relaxation techniques or administering lorazepam are inappropriate as they can worsen the acidosis by suppressing the compensatory respiratory effort.
