Nursing Elites

1. In which of the following conditions might increased cortisol levels be found?

• A. Cushing's syndrome
• B. Addison's disease
• C. Renal failure
• D. Congestive heart failure

Correct answer: A

Rationale: Cushing's syndrome is characterized by increased cortisol levels due to the overproduction of cortisol by the adrenal glands. This excess cortisol can lead to various symptoms and complications. Addison's disease is associated with decreased cortisol levels as it results from adrenal insufficiency, making it an incorrect choice in this context. Renal failure and congestive heart failure are not typically linked to abnormal cortisol levels, further indicating that they are not the conditions where increased cortisol levels are found.

2. The nurse is teaching a client about sleep and gives background information on normal sleep patterns. Which of the following substances promotes sleep?

• A. serotonin
• B. cortisol
• C. alcohol
• D. narcotics

Correct answer: A

Rationale: Serotonin is a substance found in the body that promotes sleep. It plays a role in the synthesis of a hypnogenic factor that directly induces sleep. Cortisol is a stress hormone that can disrupt sleep patterns. Alcohol can disrupt REM sleep and negatively impact sleep quality. Narcotics, like alcohol, can interfere with sleep architecture and lead to poor quality sleep. Therefore, the correct answer is serotonin as it is associated with promoting sleep, while the other substances listed can have negative effects on sleep patterns.

3. The nurse provides a postoperative client with an analgesic medication and darkens the room before the client goes to sleep for the night. The nurse's actions:

• A. help decrease stimuli from the cerebral cortex.
• B. stimulate hormonal changes in the brain.
• C. help the client's circadian rhythm.
• D. alert the hypothalamus in the brain.

Correct answer: A

Rationale: The nurse's actions of providing an analgesic medication and darkening the room aim to decrease stimuli from the cerebral cortex. Reduction of environmental stimuli, especially light and noise, from the cerebral cortex, which is an area of arousal, facilitates sleep. By decreasing input to this area, the client is more likely to fall asleep and stay asleep. Choices B, C, and D are incorrect because the scenario does not involve stimulating hormonal changes, influencing the circadian rhythm, or alerting the hypothalamus.

4. Which type of diet should the nurse provide to help a client who has major burns maintain a positive nitrogen balance?

• A. high protein
• B. high carbohydrate
• C. low carbohydrate
• D. low protein

Correct answer: A

Rationale: Clients with major burns are in a hypermetabolic state, leading to increased protein catabolism. Therefore, a high-protein diet is essential to help them maintain a positive nitrogen balance and support wound healing. High carbohydrate diets do not directly contribute to achieving a positive nitrogen balance, making choice B incorrect. Similarly, low carbohydrate diets are not recommended for clients with major burns as carbohydrates provide essential energy needed for healing. Low protein diets are contraindicated for clients with major burns as they require higher protein intake to support tissue repair and prevent further breakdown.

5. While preparing a client for a bronchoscopy, a nurse notes that the client is wearing a gold necklace. What should the nurse do to safeguard the client's necklace?

• A. Ask the client for permission to lock the necklace in the hospital safe
• B. Ask the client to remove the necklace and place it in the top drawer of the bedside table
• C. Ask the client whether the necklace is gold
• D. Ask the client to sign a release to free the hospital of responsibility if the necklace is damaged or lost during the procedure

Correct answer: A

Rationale: When a client has valuables such as jewelry, the nurse should ensure their safekeeping. It is appropriate for the nurse to ask the client for permission to lock the necklace in the hospital safe to prevent loss or damage. This option prioritizes the security of the necklace while allowing the client to make an informed decision. Asking the client to sign a release form does not guarantee the necklace's safety; it only releases the hospital from liability. Placing the necklace in a bedside table drawer does not provide adequate security as it is not as secure as a hospital safe. Inquiring whether the necklace is gold is irrelevant to safeguarding the jewelry during the procedure, as the primary concern is its safekeeping.
