Nursing Elites

1. What is the function of the enzyme lactase in the digestive system?

• A. Breaks down lactose into glucose and galactose
• B. Breaks down proteins into amino acids
• C. Converts starch into maltose
• D. Breaks down fats into fatty acids

Correct answer: A

Rationale: The correct answer is A: 'Breaks down lactose into glucose and galactose.' Lactase is an enzyme in the small intestine that specifically breaks down lactose, the sugar found in milk, into glucose and galactose for absorption. Choice B is incorrect because proteins are broken down into amino acids by protease enzymes. Choice C is incorrect because the enzyme amylase converts starch into maltose. Choice D is incorrect as lipase enzymes break down fats into fatty acids.

2. The nurse is caring for a client with pericarditis. Which of the following nursing interventions will promote comfort for the client?

• A. Auscultating the client's heart sounds
• B. Provide the client with a diversionary activity
• C. Encourage deep breathing
• D. Maintain a patent intravenous access

Correct answer: B

Rationale: Providing a diversionary activity is the most appropriate nursing intervention to promote comfort for a client with pericarditis. This intervention helps to distract the patient and reduce discomfort by focusing their attention elsewhere. Auscultating heart sounds, while important for monitoring the condition, does not directly address the client's comfort. Encouraging deep breathing can be beneficial for some conditions but may not be specifically aimed at promoting comfort in pericarditis. Maintaining a patent intravenous access is essential for treatment access and management of the condition, but it does not directly promote comfort for the client.

3. The PN determines that a client with cirrhosis is experiencing peripheral neuropathy. What action should the PN take?

• A. Protect the client's feet from injury
• B. Apply a heating pad to the affected area
• C. Keep the client's feet elevated
• D. Assess the feet and legs for jaundice

Correct answer: A

Rationale: Protecting the client's feet from injury is the most appropriate action for a client with cirrhosis experiencing peripheral neuropathy. Peripheral neuropathy can lead to a loss of sensation, making the client prone to unnoticed injuries. Applying a heating pad (Choice B) is contraindicated as it may cause burns or further damage to the affected area. Keeping the client's feet elevated (Choice C) is not directly related to managing peripheral neuropathy and may not provide significant benefit. Assessing the feet and legs for jaundice (Choice D) is important for monitoring liver function in clients with cirrhosis, but in this case, the priority is to prevent injury to the feet due to decreased sensation.

4. In a group therapy setting, one member is very demanding, repeatedly interrupting others and taking most of the group time. The nurse's best response would be:

• A. Will you briefly summarize your point because others need time as well?
• B. Your behavior is obnoxious and drains the group.
• C. I am so frustrated with your behavior.
• D. To ignore the behavior and allow him to vent

Correct answer: A

Rationale: In a group therapy setting, where each member should have the opportunity to participate, it is essential for the nurse to manage disruptive behavior assertively yet respectfully. Choice A is the best response as it addresses the issue of one member dominating the group time by asking them to summarize their point briefly, allowing others to contribute. Choice B is confrontational and may alienate the individual, hindering the therapeutic process. Choice C expresses personal frustration, which is not constructive in managing the situation. Choice D of ignoring the behavior is not effective as it allows the disruptive behavior to continue, impacting the group dynamics negatively.

5. A nurse is reviewing the basal body temperature method with a couple. Which of the following statements would indicate that the teaching has been successful?

• A. I don't need to buy a special type of thermometer.
• B. I need to wait 5 minutes after smoking a cigarette before I take my temperature.
• C. I need to take my temperature before I get out of bed in the morning.
• D. I need to take my temperature at least once every day.

Correct answer: C

Rationale: The correct answer is C. Basal body temperature must be taken before getting out of bed in the morning to get an accurate reading, as even slight activity can raise body temperature and affect the results. Choice A is incorrect because a special type of thermometer is not required for basal body temperature measurement. Choice B is incorrect because smoking can affect body temperature, but the timing mentioned is not relevant to basal body temperature measurement. Choice D is incorrect because while it is essential to take the temperature consistently each day, the duration of temperature measurement is not specified, making this choice less specific compared to the correct answer.
