Nursing Elites

1. While changing a client's chest tube dressing, the nurse notes a cracking sensation when gentle pressure is applied to the skin at the insertion site. What is the best action for the nurse to take?

• A. Apply a pressure dressing around the chest tube site.
• B. Administer an oral antihistamine.
• C. Assess for allergies to topical cleaning agents.
• D. Measure the area of swelling and crackling.

Correct answer: D

Rationale: When a nurse observes crepitus around a chest tube site, it could indicate subcutaneous emphysema, a potentially serious condition where air gets trapped under the skin. Measuring the area of swelling and crackling is important as it helps monitor the progression of subcutaneous emphysema. Applying a pressure dressing (choice A) might not address the underlying cause and could potentially worsen the condition. Administering an oral antihistamine (choice B) is not indicated for crepitus at a chest tube site. Assessing for allergies to topical cleaning agents (choice C) is important but not the immediate priority when crepitus is observed.

2. The nurse is reviewing the laboratory results of a client with chronic kidney disease. The client's serum calcium level is 7.5 mg/dL. Which condition should the nurse suspect?

• A. Hypercalcemia
• B. Hyperkalemia
• C. Hyponatremia
• D. Hypocalcemia

Correct answer: D

Rationale: A serum calcium level of 7.5 mg/dL is indicative of hypocalcemia, a common complication in clients with chronic kidney disease due to impaired calcium absorption and metabolism. Hypercalcemia (Choice A) is the opposite of the condition presented in the question and is characterized by elevated serum calcium levels. Hyperkalemia (Choice B) is an increased potassium level, not related to the client's serum calcium level. Hyponatremia (Choice C) is a decreased sodium level and is also not related to the client's serum calcium level.

3. A client on mechanical ventilation is experiencing high-pressure alarms. What action should the nurse implement first?

• A. Check the client's oxygen saturation.
• B. Assess the client's endotracheal tube for obstruction.
• C. Reposition the client to relieve pressure.
• D. Suction the client's airway.

Correct answer: B

Rationale: The correct answer is to assess the client's endotracheal tube for obstruction. When a client on mechanical ventilation experiences high-pressure alarms, the first action should be to check for any potential obstructions in the airway, which can trigger the alarms. Checking the oxygen saturation (Choice A) is important but not the priority when dealing with high-pressure alarms. Repositioning the client (Choice C) may be necessary later but should not be the initial action. Suctioning the client's airway (Choice D) should only be done after assessing for and addressing any obstructions in the endotracheal tube.

4. During an acute exacerbation of asthma, what is the nurse's first action for a client experiencing this condition?

• A. Administer a bronchodilator as prescribed.
• B. Check the client's oxygen saturation.
• C. Reassure the client and encourage deep breathing.
• D. Provide emotional support to reduce anxiety.

Correct answer: A

Rationale: The correct first action when managing an acute exacerbation of asthma is to administer a bronchodilator as prescribed. Bronchodilators help open the airways and improve breathing in individuals experiencing an asthma exacerbation. Checking oxygen saturation (Choice B) is important but not the first action. Reassuring the client and encouraging deep breathing (Choice C) can be beneficial but should come after administering the bronchodilator. Providing emotional support to reduce anxiety (Choice D) is important but is not the initial priority in managing an acute exacerbation of asthma.

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.
