Nursing Elites

1. 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.

2. What should be the first action upon the discovery of an electrical fire?

• A. Disconnect the electrical power if it can be done safely
• B. Smother the source with an object like a blanket
• C. Saturate the source with water or another liquid
• D. Immediately activate the fire alarm

Correct answer: A

Rationale: The correct initial action upon discovering an electrical fire is to disconnect the electrical power if it can be done safely. This helps prevent the fire from spreading through the electrical system. Smothering the fire with a blanket is not recommended for electrical fires as it can fuel the fire. Saturating the source with water or other liquids is also not advised as it can lead to electric shock or spread the fire. Activating the fire alarm is important, but it should be done after disconnecting the power to prevent further escalation of the fire.

3. How does cancer affect pain tolerance in elderly clients?

• A. Remain constant.
• B. Decrease.
• C. Increase.
• D. Cancer has no impact on pain tolerance in elderly clients.

Correct answer: B

Rationale: Pain tolerance in elderly clients with cancer is likely to decrease due to factors such as diminished adaptative capacity, increased physical discomfort, and the psychological impact of the disease. Cancer is known to cause various physical and emotional stressors that can lower the pain threshold, leading to a decrease in pain tolerance. Choices A, C, and D are incorrect because cancer and its associated effects typically result in a decrease in pain tolerance rather than remaining constant, increasing, or having no impact.

4. Which of the following represents a normal serum potassium level?

• A. 1.5 mEq/L
• B. 3.0 mEq/L
• C. 4.0 mEq/L
• D. 6.0 mEq/L

Correct answer: C

Rationale: The correct answer is 4.0 mEq/L. Normal serum potassium levels typically range from 3.5-5.5 mEq/L. Choice A (1.5 mEq/L) is below the normal range, Choice B (3.0 mEq/L) is also below the normal range, and Choice D (6.0 mEq/L) is above the normal range. Therefore, the only option within the normal range is Choice C (4.0 mEq/L).

5. The nurse notes that a healthcare provider has documented the following prescription in a client's record: Furosemide (Lasix) 40 mg stat once. What action should the nurse take?

• A. Administering the medication
• B. Drawing up the medication in a syringe
• C. Planning to have the nurse on the next shift administer the medication
• D. Contacting the healthcare provider

Correct answer: D

Rationale: The correct action for the nurse to take in this situation is to contact the healthcare provider. The prescription provided lacks crucial information such as the route of administration. Before administering any medication, the nurse must clarify any missing details with the provider, especially for a stat prescription that requires immediate administration. Drawing up or administering the medication without verifying the route of administration is unsafe and can lead to errors. Planning for the next shift nurse to administer the medication is not appropriate in this scenario as the stat order necessitates immediate action. Therefore, the best course of action is to contact the healthcare provider to obtain clarification on the prescription.
