Nursing Elites

1. Prior to elective surgery, a patient taking warfarin should receive which instruction regarding warfarin therapy?

• A. Continue taking warfarin until the day of surgery.
• B. Stop taking warfarin three days before surgery.
• C. Switch to aspirin before surgery.
• D. Stop taking warfarin one week before surgery.

Correct answer: D

Rationale: Prior to elective surgery, a patient taking warfarin should be instructed to stop taking warfarin around one week before the procedure. This timeframe allows for the effects of warfarin to diminish, lowering the risk of excessive bleeding during surgery. Continuing warfarin until the day of surgery (Choice A) increases the risk of bleeding complications. Stopping warfarin three days before surgery (Choice B) may not provide enough time for the anticoagulant effects to subside. Switching to aspirin before surgery (Choice C) is not recommended as a substitute for warfarin in this context.

2. A 38-year-old male client collapsed at his outside construction job in Texas in July. His admitting vital signs to ICU are, BP 82/70, heart rate 140 beats/minute, urine output 10 ml/hr, skin cool to the touch. Pulmonary artery (PA) pressures are, PAWP 1, PAP 8/2, RAP -1, SVR 1600. What nursing action has the highest priority?

• A. Apply a hypothermia unit to stabilize core temperature.
• B. Increase the client's IV fluid rate to 200 ml/hr.
• C. Call the hospital chaplain to counsel the family.
• D. Draw blood cultures x3 to detect infection.

Correct answer: B

Rationale: The correct answer is to increase the client's IV fluid rate to 200 ml/hr. The client's vital signs indicate signs of shock and hypovolemia, making fluid resuscitation the priority to address these conditions. Improving intravascular volume is crucial to stabilize the client's blood pressure, heart rate, and urine output, ultimately improving organ perfusion and addressing the underlying issue of hypovolemia.

3. What is the primary action of amlodipine when prescribed to a patient with hypertension?

• A. Increase heart rate
• B. Reduce blood pressure
• C. Lower cholesterol levels
• D. Decrease blood sugar levels

Correct answer: B

Rationale: Amlodipine is a calcium channel blocker that works by relaxing the blood vessels, leading to a reduction in blood pressure. This medication does not increase heart rate, lower cholesterol levels, or decrease blood sugar levels.

4. A patient with anemia is prescribed ferrous sulfate. What advice should the nurse give regarding the administration of this medication?

• A. Take with dairy products to increase absorption.
• B. Take on an empty stomach for best absorption.
• C. Avoid vitamin C while taking this medication.
• D. Take before bedtime.

Correct answer: B

Rationale: The correct advice for the administration of ferrous sulfate is to take it on an empty stomach for best absorption. This enhances the absorption of iron. If gastrointestinal upset occurs, the medication can be taken with food. Taking ferrous sulfate with dairy products is not recommended as calcium can inhibit iron absorption. Taking it before bedtime is also not recommended. Vitamin C can actually help with the absorption of iron and is often recommended to be taken alongside iron supplements to enhance absorption. Therefore, avoiding vitamin C while taking ferrous sulfate is not correct.

5. The nurse formulates a nursing diagnosis of 'High risk for ineffective airway clearance' for a client with myasthenia gravis. What is the most likely etiology for this nursing diagnosis?

• A. Pain when coughing.
• B. Diminished cough effort.
• C. Thick, dry secretions.
• D. Excessive inflammation.

Correct answer: B

Rationale: The correct answer is B: Diminished cough effort. Clients with myasthenia gravis often experience muscle weakness, including respiratory muscles, which can lead to diminished cough effort. This weakness can result in ineffective airway clearance, putting the client at a high risk. Pain when coughing (choice A) is not directly related to the etiology of ineffective airway clearance in myasthenia gravis. While thick, dry secretions (choice C) and excessive inflammation (choice D) can contribute to airway clearance issues, the primary concern in myasthenia gravis is the muscle weakness affecting cough effort.
