Nursing Elites

1. A patient with a diagnosis of deep vein thrombosis (DVT) is receiving heparin therapy. Which laboratory test should the nurse monitor to evaluate the effectiveness of the heparin therapy?

• A. Prothrombin time (PT)
• B. Partial thromboplastin time (PTT)
• C. Bleeding time
• D. Platelet count

Correct answer: B

Rationale: The correct answer is B: Partial thromboplastin time (PTT). Heparin affects the intrinsic pathway of the coagulation cascade, which is reflected by changes in the PTT. Monitoring the PTT helps ensure that the patient's blood is within the desired therapeutic range and prevents complications related to clotting or bleeding. Prothrombin time (PT) primarily assesses the extrinsic pathway and is not as sensitive to heparin therapy. Bleeding time and platelet count are not specific tests for monitoring the effectiveness of heparin therapy in DVT.

2. The nurse is providing an educational workshop about coronary artery disease (CAD) and its risk factors. The nurse explains to participants that CAD has many risk factors, some that can be controlled and some that cannot. What risk factors should the nurse list that can be controlled or modified?

• A. Gender, obesity, family history, and smoking
• B. Inactivity, stress, gender, and smoking
• C. Cholesterol levels, hypertension, and smoking
• D. Stress, family history, and obesity

Correct answer: C

Rationale: Cholesterol levels, hypertension, and smoking are controllable risk factors for CAD. Managing these factors through lifestyle changes and medical interventions can help reduce the risk of developing coronary artery disease.

3. A 35-year-old man presents with difficulty swallowing, weight loss, and regurgitation of undigested food. A barium swallow shows a 'bird beak' appearance of the lower esophagus. What is the most likely diagnosis?

• A. Esophageal cancer
• B. Achalasia
• C. Peptic stricture
• D. Gastroesophageal reflux disease

Correct answer: B

Rationale: The 'bird beak' appearance on a barium swallow is characteristic of achalasia, a condition where the lower esophageal sphincter fails to relax properly. This leads to difficulty swallowing, weight loss, and regurgitation of undigested food, which are hallmark symptoms of achalasia.

4. What instruction should the nurse give regarding the administration of alendronate to a patient with osteoporosis?

• A. Take the medication with milk.
• B. Lie down for 30 minutes after taking the medication.
• C. Take the medication with a full glass of water.
• D. Take the medication before bedtime.

Correct answer: C

Rationale: The correct instruction for administering alendronate to a patient with osteoporosis is to take the medication with a full glass of water first thing in the morning. It is important for the patient to remain upright for at least 30 minutes after taking the medication to prevent esophageal irritation. Taking alendronate with milk, lying down after intake, or taking it before bedtime can reduce the medication's effectiveness or increase the risk of side effects.

5. An adolescent patient seeks care in the emergency department after sharing needles for heroin injection with a friend who has hepatitis B. To provide immediate protection from infection, what medication will the nurse administer?

• A. Corticosteroids
• B. Gamma globulin
• C. Hepatitis B vaccine
• D. Fresh frozen plasma

Correct answer: B

Rationale: In this scenario, the immediate need is to provide passive immunity to the adolescent patient. Gamma globulin contains antibodies against hepatitis B, which can offer immediate protection. The hepatitis B vaccine provides active immunity over time but is not immediate. Fresh frozen plasma and corticosteroids are not indicated for immediate protection against hepatitis B infection. Therefore, the correct choice is Gamma globulin as it can provide immediate passive immunity against hepatitis B.
