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 rheumatoid arthritis is prescribed methotrexate. What is the most important teaching point for the nurse to provide?

• A. Take the medication with food to avoid gastrointestinal upset.
• B. Monitor for signs of infection, such as a sore throat.
• C. Increase fluid intake to prevent dehydration.
• D. Avoid direct sunlight to prevent photosensitivity.

Correct answer: D

Rationale: The most important teaching point for a client prescribed methotrexate is to avoid direct sunlight to prevent photosensitivity. Methotrexate can make the skin more sensitive to sunlight, increasing the risk of sunburn and skin damage. Choices A, B, and C are important aspects of client care but are not specifically related to the side effect of photosensitivity caused by methotrexate.

3. A client is scheduled for a spiral CT scan with contrast to evaluate for pulmonary embolism. Which information in the client's history requires follow-up by the nurse?

• A. Is allergic to shellfish
• B. Has a history of smoking
• C. Takes metformin for type 2 diabetes mellitus
• D. Has hypertension controlled with medication

Correct answer: A

Rationale: An allergy to shellfish often indicates an allergy to iodine, which is used in contrast dyes for CT scans. This poses a significant risk of an allergic reaction during the procedure. The nurse must ensure appropriate precautions or alternative imaging are considered. Choices B, C, and D are not directly contraindicated for a CT scan with contrast. Smoking history, metformin use, and controlled hypertension do not typically impact the safety or feasibility of the procedure.

4. A client with a history of coronary artery disease is experiencing chest pain. What is the nurse's first action?

• A. Administer sublingual nitroglycerin
• B. Obtain a 12-lead electrocardiogram
• C. Call the healthcare provider
• D. Check the client's oxygen saturation

Correct answer: A

Rationale: The correct answer is A: Administer sublingual nitroglycerin. Sublingual nitroglycerin is the first-line treatment for chest pain related to coronary artery disease. It helps dilate the coronary arteries and improve blood flow to the heart, providing immediate relief from ischemia. Administering nitroglycerin promptly can help alleviate the chest pain and prevent further complications. Obtaining a 12-lead electrocardiogram (Choice B) is important but should not delay the administration of nitroglycerin. Calling the healthcare provider (Choice C) can be done after initiating immediate treatment. Checking the client's oxygen saturation (Choice D) is relevant but not the first action to take in this scenario.

5. A young male client with an above-knee amputation (AKA) reports that his 'right foot is aching.' What is the most important intervention for the nurse to implement?

• A. Encourage discussion of feelings about the loss of his limb.
• B. Administer a prescription for gabapentin.
• C. Teach the client how to wrap the stump with an elastic bandage.
• D. Offer to assist the client to a quieter location to relax.

Correct answer: B

Rationale: The correct answer is B because gabapentin is prescribed to treat phantom limb pain, which is common in individuals with amputations. Option A is not the most important intervention at this time since the client is reporting physical pain, not emotional distress. Option C is not appropriate because the client is reporting aching in the foot, not the stump. Option D does not address the underlying issue of phantom limb pain that needs to be managed.
