Nursing Elites

1. A client is to receive thrombolytic therapy. Which of the following factors should be recognized as a contraindication to the therapy?

• A. Hip arthroplasty 2 weeks ago
• B. Elevated sedimentation rate
• C. Incident of exercise-induced asthma 1 week ago
• D. Elevated platelet count

Correct answer: A

Rationale: Thrombolytic therapy involves the use of medications to dissolve blood clots. Hip arthroplasty (joint replacement surgery) performed recently is a contraindication to thrombolytic therapy due to the risk of bleeding. Elevated sedimentation rate, exercise-induced asthma, and elevated platelet count are not contraindications to thrombolytic therapy.

2. A patient is kept off food and fluids for 10 hours before surgery. His oral temperature at 8 a.m. is 99.8°F (37.7°C). This temperature reading probably indicates:

• A. Infection
• B. Hypothermia
• C. Anxiety
• D. Dehydration

Correct answer: D

Rationale: A patient being kept off food and fluids before surgery can lead to dehydration. Dehydration can cause a slight increase in body temperature, which could explain the elevated oral temperature reading of 99.8°F (37.7°C) in this scenario. Infections are more likely to cause higher fevers, hypothermia would present with a lower temperature, and anxiety typically does not directly affect body temperature in this manner.

3. What is the primary purpose of a platelet count?

• A. Assessing clot formation potential
• B. Assessing bleeding risk
• C. Detecting antigen-antibody response
• D. Identifying cardiac enzymes presence

Correct answer: B

Rationale: A platelet count is primarily used to assess the risk of bleeding. Platelets play a crucial role in blood clotting, so a low platelet count can lead to an increased risk of bleeding. Monitoring platelet levels helps healthcare providers evaluate a patient's ability to form clots and manage bleeding.

4. A healthcare professional is caring for a client who is experiencing respiratory distress. Which of the following early manifestations of hypoxemia should the professional recognize?

• A. Confusion
• B. Pale skin
• C. Bradycardia
• D. Hypotension

Correct answer: B

Rationale: Pale skin is an early manifestation of hypoxemia due to decreased oxygenation of the blood. The skin may appear pale as the body redirects blood flow to vital organs in response to low oxygen levels. Confusion, bradycardia, and hypotension may occur as hypoxemia worsens, but pale skin is one of the initial signs that healthcare professionals should recognize when assessing a client experiencing respiratory distress.

5. A nurse is providing teaching about gastrostomy tube feedings to the parents of a school-age child. Which of the following instructions should the nurse give?

• A. Administer the feeding over 30 minutes
• B. Place the child in a supine position after the feeding
• C. Change the feeding bag and tubing every 3 days
• D. Warm the formula in a warm water bath before administration

Correct answer: B

Rationale: Administering the feeding over 30 minutes helps prevent complications such as aspiration. Placing the child in an upright position after the feeding is recommended to reduce the risk of aspiration. It is essential to change the feeding bag and tubing every 3 days to maintain asepsis and prevent infections. Warming the formula in a warm water bath is the correct method as using a microwave can create hot spots that may burn the child's mouth or throat.
