Nursing Elites

1. Where in the body are microvilli located, facilitating the absorption of most nutrients?

• A. Stomach
• B. Pancreas
• C. Large Intestine
• D. Small Intestine

Correct answer: D

Rationale: The correct answer is D: Small Intestine. Microvilli are present in the small intestine, significantly increasing its surface area for efficient absorption of nutrients. The small intestine is the primary site for nutrient absorption in the body. The stomach (choice A) primarily functions to break down food with its acidic environment but is not where most nutrients are absorbed. The pancreas (choice B) produces enzymes to aid in digestion but does not directly absorb nutrients. The large intestine (choice C) mainly absorbs water and electrolytes from undigested food, rather than nutrients.

2. What condition has been shown to be associated with esophageal dysphagia?

• A. myasthenia gravis
• B. achalasia
• C. Alzheimer's disease
• D. cerebral palsy

Correct answer: B

Rationale: Achalasia is the correct answer. It is a condition characterized by the esophagus having difficulty moving food toward the stomach, resulting in dysphagia (difficulty swallowing). Myasthenia gravis (Choice A) is a neuromuscular disorder that affects skeletal muscles, not the esophagus. Alzheimer's disease (Choice C) primarily affects cognitive function, not the esophagus. Cerebral palsy (Choice D) is a neurological disorder affecting body movement and muscle coordination, unrelated to esophageal dysphagia.

3. Mr. Bradley has been advised to limit his dairy product intake. What principle regarding fluid intake should be followed?

• A. Gelatin, soups, fruit ices, and frozen fruit bars contribute to your fluid intake
• B. Drink milk in moderation
• C. Increase fiber intake
• D. Limit protein intake

Correct answer: A

Rationale: For patients with kidney disease, it's important to manage fluid intake from all sources, including foods like gelatin and soups, which can contribute to fluid overload.

4. Low levels of physical activity are more commonly associated with which type of cancer?

• A. Esophageal cancer
• B. Pancreatic cancer
• C. Lung cancer
• D. Colon cancer

Correct answer: D

Rationale: Low physical activity is most strongly associated with an increased risk of colon cancer. Regular exercise helps regulate bowel movements and reduce inflammation, which are factors that can contribute to the development of colon cancer. Esophageal cancer, pancreatic cancer, and lung cancer are not as directly linked to low levels of physical activity.

5. Aling Maria is nearing menopause. She is habitually taking cola and coffee for the past 20 years. You should tell Aling Maria to avoid taking caffeinated beverages because:

• A. It is stimulating
• B. It will cause nervousness and insomnia
• C. It will contribute to additional bone demineralization
• D. It will cause tachycardia and arrhythmias

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.
