Nursing Elites

1. Located in the middle of the brain, what organ is responsible for satiety and hunger?

• A. Medulla Oblongata
• B. Pituitary Gland
• C. Hypothalamus
• D. Parathyroid

Correct answer: C

Rationale: The hypothalamus, located in the middle of the brain, plays a crucial role in regulating hunger and satiety. It contains specific regions that control appetite and feeding behavior. The Medulla Oblongata (Choice A) is responsible for regulating vital functions like heartbeat and breathing, not hunger. The Pituitary Gland (Choice B) is an endocrine gland that secretes hormones but is not primarily involved in hunger regulation. The Parathyroid (Choice D) is responsible for regulating calcium levels in the body and not related to hunger or satiety.

2. Which of the four phases of emergency management is defined as 'sustained action that reduces or eliminates long-term risk to people and property from natural hazards and their effects'?

• A. Recovery
• B. Mitigation
• C. Response
• D. Preparedness

Correct answer: B

Rationale: The correct answer is B, 'Mitigation.' Mitigation is the phase of emergency management that focuses on sustained actions aimed at reducing or eliminating long-term risks to people and property from natural hazards. Recovery (A) involves restoring and rebuilding infrastructure, housing, and services after a disaster. Response (C) deals with immediate actions taken to save lives and prevent further damage during a disaster. Preparedness (D) involves planning, training, and equipping organizations and communities to effectively respond to emergencies.

3. Dietary fiber has been recommended for its possible benefits in reducing heart disease by lowering blood cholesterol. How is fiber thought to play its role in lowering blood cholesterol?

• A. Insoluble fiber binds with cholesterol in the large intestine and is excreted in feces
• B. Viscous fiber binds with bile in the intestine and is excreted in feces
• C. Soluble fiber binds with cholesterol in the blood and is excreted by the liver
• D. Insoluble fiber converts to bile in the large intestine and binds with cholesterol

Correct answer: B

Rationale: The correct answer is B. Viscous (soluble) fiber binds with bile acids in the intestine, which are then excreted. The liver must use cholesterol to make more bile acids, thereby lowering blood cholesterol levels. Choice A is incorrect as insoluble fiber does not bind with cholesterol in the large intestine. Choice C is incorrect as soluble fiber does not directly bind with cholesterol in the blood. Choice D is incorrect as insoluble fiber does not convert to bile in the large intestine to bind with cholesterol.
