Nursing Elites

1. Prolonged exposure to high concentrations of supplemental oxygen over several days can cause which pathophysiological effect?

• A. Reduced cardiac output
• B. Disrupted surfactant production
• C. Hyperactivity of alveoli
• D. Increased oxygen carrying capacity

Correct answer: B

Rationale: Corrected Rationale: Prolonged exposure to high oxygen concentrations can disrupt the production of surfactant in the lungs, leading to atelectasis and other lung complications. Surfactant is essential for maintaining lung compliance and preventing alveolar collapse. Reduced cardiac output (Choice A) is not directly associated with prolonged oxygen exposure. Hyperactivity of alveoli (Choice C) is not a recognized consequence of high oxygen levels. Increased oxygen carrying capacity (Choice D) is not a pathophysiological effect of prolonged high oxygen exposure.

2. A client with deep vein thrombosis (DVT) is prescribed warfarin. What teaching should the nurse provide?

• A. Avoid foods high in vitamin K, such as spinach.
• B. Report any signs of bleeding, such as bruising or nosebleeds.
• C. Take the medication on an empty stomach.
• D. Monitor for changes in blood pressure.

Correct answer: B

Rationale: The correct teaching for a client prescribed warfarin is to report any signs of bleeding, such as unusual bruising, nosebleeds, or blood in the urine or stool. Warfarin is an anticoagulant that increases the risk of bleeding, so it is crucial for the client to promptly report any bleeding-related symptoms for evaluation by a healthcare provider. Choices A, C, and D are incorrect. Avoiding foods high in vitamin K, such as spinach, is more relevant for clients taking warfarin to maintain consistent vitamin K intake. Warfarin should be taken with food to avoid gastrointestinal upset, so taking it on an empty stomach is not recommended. Monitoring for changes in blood pressure is not directly related to warfarin therapy; instead, the focus should be on monitoring for signs of bleeding.

3. What safety measure should the nurse take for a client with a seizure disorder who has an IV line?

• A. Ensure that the IV site is padded and protected.
• B. Limit the client's mobility to prevent dislodging the IV.
• C. Place the IV site on the same side as the seizure activity.
• D. Ensure the client is positioned on the opposite side of the IV line.

Correct answer: D

Rationale: The correct answer is D: Ensure the client is positioned on the opposite side of the IV line. Placing the IV line on the opposite side of any seizure activity is essential to prevent injury. It helps to ensure that the IV line is not dislodged during a seizure. Choices A, B, and C are incorrect. While padding and protecting the IV site is important, the priority is to position the client on the side opposite to the IV line to prevent dislodgement and injury during a seizure.

4. A nurse receives a report on a client who is four hours post-total abdominal hysterectomy. The previous nurse reported that it was necessary to change the client's perineal pad hourly and that it is again saturated. The previous nurse also reports that the client's urinary output has decreased. Which action should the nurse implement first?

• A. Measure urinary output
• B. Assess for weakness or dizziness
• C. Increase IV fluids
• D. Check for vaginal bleeding

Correct answer: D

Rationale: Saturation of the perineal pad after a hysterectomy suggests excessive vaginal bleeding, which must be addressed immediately. Assessing for vaginal bleeding is the priority in this situation as it can lead to hypovolemic shock. Measuring urinary output, assessing for weakness or dizziness, and increasing IV fluids are important interventions but checking for vaginal bleeding takes precedence due to the risk of hemorrhage post-hysterectomy.

5. A client is prescribed an inhaled corticosteroid for asthma management. Which instruction should the nurse provide to the client regarding the use of this medication?

• A. Rinse your mouth after using the inhaler
• B. Hold your breath for 5 seconds after inhaling the medication
• C. Use the inhaler during an acute asthma attack
• D. Take the medication only when symptoms occur

Correct answer: A

Rationale: The correct instruction for a client using an inhaled corticosteroid for asthma management is to rinse the mouth after using the inhaler. This helps prevent oral thrush, a common side effect of corticosteroid inhalers. Holding the breath for 5 seconds after inhaling the medication (Choice B) is not necessary for corticosteroid inhalers. Using the inhaler during an acute asthma attack (Choice C) is not the purpose of corticosteroids, which are used for long-term asthma management. Taking the medication only when symptoms occur (Choice D) is not correct as corticosteroids are typically used regularly to control asthma symptoms.
