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. The nurse is caring for a client with chronic heart failure who is receiving digoxin therapy. The nurse reviews the client's lab results and notes that the serum potassium level is 3.0 mEq/L. What action should the nurse take next?

• A. Administer a potassium supplement
• B. Notify the healthcare provider
• C. Hold the next dose of digoxin
• D. Increase dietary potassium intake

Correct answer: C

Rationale: In clients receiving digoxin therapy, low potassium levels can increase the risk of digoxin toxicity. Therefore, when the nurse notes a serum potassium level of 3.0 mEq/L, it is crucial to hold the next dose of digoxin. Notifying the healthcare provider is essential to ensure appropriate interventions, such as potassium supplementation, can be implemented. Administering a potassium supplement without healthcare provider guidance may lead to rapid potassium level changes and potential adverse effects. Increasing dietary potassium intake alone may not promptly address the low serum potassium level in this acute situation.

3. A client with a urinary tract infection is prescribed ciprofloxacin. What is the nurse's priority teaching?

• A. Take the medication with a full glass of water.
• B. Avoid direct sunlight while taking the medication.
• C. Take the medication with meals to prevent nausea.
• D. Discontinue the medication if you experience dizziness.

Correct answer: A

Rationale: The correct answer is A: 'Take the medication with a full glass of water.' It is crucial for the nurse to teach the client to take ciprofloxacin with a full glass of water to prevent crystalluria, a potential side effect of the medication. Choice B is incorrect because ciprofloxacin does not require avoiding direct sunlight. Choice C is incorrect as taking the medication with meals is not necessary to prevent nausea. Choice D is incorrect as dizziness is not a common reason to discontinue ciprofloxacin.

4. The nurse is caring for a seated client experiencing a tonic-clonic seizure. Which actions should the nurse implement?

• A. Place a padded tongue depressor in the client's mouth
• B. Restrain the client and attempt to stop the seizure
• C. Begin CPR immediately
• D. Loosen restrictive clothing and ease the client to the floor

Correct answer: D

Rationale: During a tonic-clonic seizure, the nurse should loosen restrictive clothing to prevent injury and ease the client to the floor to ensure safety. Placing any object, such as a tongue depressor, in the client's mouth is contraindicated as it may cause harm. Restraint should not be used as it can lead to injury. Beginning CPR is not indicated during a seizure unless the client experiences cardiac arrest, which is a rare complication of seizures.

5. An older male client, who is a retired chef, is hospitalized with a diabetic ulcer on his foot. His daughter tells the nurse that her father has become increasingly obsessed with the way his food is prepared in the hospital. The nurse's response should be based on what information?

• A. His daughter's observations suggest the client is depressed
• B. His compulsiveness about food may indicate new cognitive decline
• C. Obsessiveness with food is common in diabetic clients
• D. If the client was compulsive about food when he was younger, the aging process can magnify this

Correct answer: D

Rationale: Age can magnify pre-existing compulsive tendencies. If the client was detail-oriented about food earlier in life, this behavior may intensify with aging. It's important to acknowledge and address the client's concerns respectfully. Choices A, B, and C are incorrect because the daughter's observations do not necessarily point to depression, the compulsiveness about food does not indicate new cognitive decline without further assessment, and obsessiveness with food is not specifically common in diabetic clients.
