Nursing Elites

1. A patient with atrial fibrillation is prescribed warfarin. Which laboratory test should the nurse monitor to assess the effectiveness of the medication?

• A. Complete blood count (CBC)
• B. Prothrombin time (PT)/INR
• C. Partial thromboplastin time (PTT)
• D. Serum potassium level

Correct answer: B

Rationale: The correct answer is B: Prothrombin time (PT)/INR. Warfarin affects the clotting ability of the blood by inhibiting vitamin K-dependent clotting factors. Monitoring the prothrombin time (PT) and international normalized ratio (INR) is crucial to assess the effectiveness and safety of warfarin therapy. These tests help determine if the patient is within the desired anticoagulation range to prevent either clotting issues or excessive bleeding.

2. The healthcare provider is assessing a client with chronic obstructive pulmonary disease (COPD). Which finding should the provider expect?

• A. Increased anteroposterior chest diameter.
• B. Decreased respiratory rate.
• C. Dull percussion sounds over the lungs.
• D. Hyperresonance on chest percussion.

Correct answer: A

Rationale: The correct answer is A: Increased anteroposterior chest diameter. The increased anteroposterior chest diameter, often referred to as a barrel chest, is a common finding in clients with COPD due to hyperinflation of the lungs. This occurs because of the loss of lung elasticity and air trapping, leading to a more rounded chest shape. Choices B, C, and D are incorrect. Decreased respiratory rate is not typically associated with COPD; instead, an increased respiratory rate may be seen due to the body's compensatory mechanisms. Dull percussion sounds and hyperresonance on chest percussion are not characteristic findings in COPD. Dull percussion sounds may be indicative of consolidation or pleural effusion, while hyperresonance is more commonly associated with conditions like emphysema.

3. 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.

4. While assessing a client with preeclampsia who is receiving magnesium sulfate, the nurse notes her deep tendon reflexes are 1+, respiratory rate is 12 breaths/minute, urinary output is 90 ml in 4 hours, and magnesium sulfate level is 9 mg/dl. What intervention should the nurse implement based on these findings?

• A. Continue the magnesium sulfate infusion as prescribed.
• B. Decrease the magnesium sulfate infusion by one-half.
• C. Stop the magnesium sulfate infusion immediately.
• D. Administer calcium gluconate immediately.

Correct answer: C

Rationale: The nurse should stop the magnesium sulfate infusion immediately in a client with preeclampsia exhibiting diminished reflexes, respiratory depression, and low urinary output, which indicate magnesium sulfate toxicity. This action is crucial to prevent further complications and adverse effects on the client.

5. A 28-year-old woman presents with abdominal pain, diarrhea, and rectal bleeding. She has a history of similar episodes in the past. What is the most likely diagnosis?

• A. Ulcerative colitis
• B. Irritable bowel syndrome
• C. Celiac disease
• D. Diverticulitis

Correct answer: A

Rationale: The constellation of symptoms including abdominal pain, diarrhea, and rectal bleeding in a young woman with a history of similar episodes is highly suggestive of ulcerative colitis. This chronic inflammatory condition primarily affects the colon and rectum, leading to symptoms such as bloody diarrhea, abdominal pain, and urgency. The recurrent nature of her symptoms and the presence of rectal bleeding further support this diagnosis over other conditions listed, such as irritable bowel syndrome, celiac disease, or diverticulitis, which typically do not present with the same combination of symptoms and history.
