Nursing Elites

1. A client with a history of deep vein thrombosis (DVT) is receiving warfarin (Coumadin). Which laboratory value indicates a therapeutic effect of the medication?

• A. INR of 2.5.
• B. PTT of 45 seconds.
• C. Hemoglobin of 12 g/dL.
• D. Platelet count of 150,000/mm³.

Correct answer: A

Rationale: An INR (International Normalized Ratio) of 2.5 indicates a therapeutic level for clients receiving warfarin (Coumadin) to prevent thromboembolism. It is essential to monitor INR levels regularly when on warfarin therapy to ensure that the blood's ability to clot is within the desired range to prevent both clotting and excessive bleeding.

2. A client with a diagnosis of rheumatoid arthritis is experiencing severe pain. Which medication is likely to be prescribed?

• A. Acetaminophen (Tylenol)
• B. Ibuprofen (Advil)
• C. Methotrexate (Rheumatrex)
• D. Prednisone (Deltasone)

Correct answer: C

Rationale: Methotrexate is commonly prescribed for rheumatoid arthritis to reduce inflammation and slow disease progression. It is a disease-modifying antirheumatic drug (DMARD) that helps control symptoms and prevent joint damage in individuals with rheumatoid arthritis. While acetaminophen and ibuprofen are used for pain relief, they are not typically prescribed to address the underlying inflammation and disease progression associated with rheumatoid arthritis. Prednisone may be used for short-term symptom relief or during disease flares, but it is not a first-line treatment for rheumatoid arthritis.

3. An otherwise healthy 45-year-old man presents with severe hematochezia and moderate abdominal cramping since this morning. A barium enema one year ago was normal. On examination, his blood pressure is 120/78 and pulse is 100 while lying; when standing, the blood pressure is 110/76 and pulse is 136. His hematocrit is 34. What is the most likely cause of bleeding?

• A. Diverticular bleed
• B. Duodenal ulcer
• C. Inflammatory bowel disease
• D. Vascular ectasia (watermelon stomach)

Correct answer: B

Rationale: The patient's presentation with hematochezia, moderate abdominal cramping, and hemodynamic changes (increased pulse on standing) suggests an upper gastrointestinal bleed. The drop in blood pressure and rise in pulse rate when standing indicate orthostatic hypotension, which is a sign of significant blood loss. The absence of melena does not rule out an upper GI bleed. Ulcers in the duodenal bulb can erode into the gastroduodenal artery, leading to brisk blood loss. A normal barium enema one year ago makes diverticular bleeding less likely. Inflammatory bowel disease usually does not cause severe acute GI bleeding unless there is ulceration into a vessel. Vascular ectasia, like watermelon stomach, typically presents with chronic blood loss and iron deficiency anemia, more common in older women. The absence of vomiting and the presence of hematochezia make Mallory-Weiss tear less likely in this case.

4. A client with hyperthyroidism is prescribed propylthiouracil (PTU). Which instruction should the nurse include in the client's discharge teaching?

• A. Report any signs of infection, such as sore throat or fever, to your healthcare provider.'
• B. Increase your intake of iodine-rich foods, such as seafood and dairy products.'
• C. Take the medication on an empty stomach for better absorption.'
• D. You may experience weight gain and fatigue as side effects of the medication.'

Correct answer: A

Rationale: Propylthiouracil (PTU) can suppress bone marrow function, increasing the risk of infection, so it is important to report signs of infection promptly.

5. A client with a history of chronic alcohol abuse is at risk for which of the following conditions?

• A. Liver cirrhosis
• B. Renal failure
• C. Chronic obstructive pulmonary disease (COPD)
• D. Peptic ulcer disease

Correct answer: A

Rationale: Chronic alcohol abuse can lead to liver cirrhosis due to long-term liver damage. Alcohol consumption over time can cause inflammation and scarring of the liver, eventually leading to cirrhosis. This condition can severely impact liver function and may progress to liver failure if not addressed.
