Nursing Elites

1. A client reports unilateral leg swelling after a long flight. What complication is the nurse most concerned about?

• A. Monitor for signs of a pulmonary embolism.
• B. Assess for signs of dehydration.
• C. Monitor for signs of compartment syndrome.
• D. Check the client’s oxygen saturation levels.

Correct answer: A

Rationale: The correct answer is A. Unilateral leg swelling following a long flight may indicate a pulmonary embolism, which is a life-threatening complication requiring immediate attention. Pulmonary embolism occurs when a blood clot travels to the lungs, potentially blocking blood flow and leading to serious complications. Choices B, C, and D are incorrect because dehydration, compartment syndrome, and oxygen saturation levels are not typically associated with unilateral leg swelling after a long flight. While dehydration can cause leg cramps, compartment syndrome is more commonly associated with trauma or injury, and oxygen saturation levels are not the primary concern in this scenario.

2. What is the expected outcome of prescribing a proton pump inhibitor to a client with a peptic ulcer?

• A. Promote healing of the gastric mucosa.
• B. Neutralize the effects of stomach acid.
• C. Inhibit the growth of Helicobacter pylori.
• D. Reduce gastric acid secretion.

Correct answer: D

Rationale: The correct answer is D: Reduce gastric acid secretion. Proton pump inhibitors (PPIs) work by reducing gastric acid secretion, which helps prevent further irritation of the gastric mucosa and allows ulcers to heal. While promoting healing of the gastric mucosa (Choice A) is an indirect outcome of reducing gastric acid secretion, the primary mechanism of PPIs is to lower acid levels. Choice B, neutralizing the effects of stomach acid, is typically associated with antacids, not PPIs. Inhibiting the growth of Helicobacter pylori (Choice C) is usually achieved with antibiotics, not PPIs.

3. What are the primary pathophysiological mechanisms responsible for ascites in liver failure?

• A. Decreased liver enzymes.
• B. Increased hydrostatic pressure in portal circulation.
• C. High bilirubin levels.
• D. Fluid shifts due to decreased serum proteins.

Correct answer: B

Rationale: The correct answer is B: Increased hydrostatic pressure in portal circulation. Ascites in liver failure is primarily caused by fluid shifts from the intravascular space to the interstitial space due to increased hydrostatic pressure in the portal circulation. Choice A is incorrect as ascites is not caused by decreased liver enzymes. Choice C is incorrect as high bilirubin levels are not the primary mechanism for ascites in liver failure. Choice D is incorrect as fluid shifts in ascites are due to decreased serum proteins, not increased serum proteins.

4. The nurse is preparing to administer a blood transfusion to a client. Which action is most important for the nurse to take before starting the transfusion?

• A. Administer pre-transfusion medication
• B. Ensure the client has an adequate fluid intake
• C. Monitor the client's vital signs
• D. Verify the blood type with another nurse

Correct answer: D

Rationale: Verifying the blood type with another nurse is critical before starting a blood transfusion to prevent a potentially life-threatening transfusion reaction. This step ensures that the client receives the correct blood product. Administering pre-transfusion medication, ensuring adequate fluid intake, and monitoring vital signs are important steps during the transfusion process, but verifying the blood type is the most crucial step to ensure patient safety.

5. 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.
