1. What kinds of foods do people who live in food deserts typically lack?

• A. fresh fruits and vegetables
• B. energy-dense foods
• C. beef or pork products
• D. grains and cereals

Correct answer: A

Rationale: Correct Answer: Fresh fruits and vegetables are often unavailable in food deserts, where access to nutritious, perishable foods is limited. Choice B, energy-dense foods, is incorrect because these are more likely to be available in food deserts, contributing to health issues. Choice C, beef or pork products, is incorrect as the focus is on the lack of fresh produce. Choice D, grains and cereals, is incorrect as these are staple foods that are more commonly found even in areas classified as food deserts.

2. What nutrition-related side effect is most likely to occur after head and neck surgery for cancer treatment?

• A. Aspiration
• B. Acid reflux
• C. Dumping syndrome
• D. Diarrhea

Correct answer: A

Rationale: The most likely nutrition-related side effect after head and neck surgery for cancer treatment is aspiration. This is due to changes in swallowing mechanics, which can cause food or liquids to be inhaled into the lungs. While acid reflux, dumping syndrome, and diarrhea are potential side effects related to nutrition, they are not as directly connected to head and neck surgery. Acid reflux is more often related to issues with the lower esophageal sphincter, dumping syndrome is typically a complication of gastric surgery, and diarrhea can have various causes, including certain medications or gastrointestinal illnesses.

3. After consuming a meal high in fat, the _____ releases _______ to aid in digestion.

• A. stomach, acid
• B. liver, bile
• C. pancreas, bicarbonate
• D. gallbladder, bile

Correct answer: D

Rationale: The gallbladder releases bile into the small intestine to help digest fats. Bile emulsifies fats, breaking them down into smaller droplets for easier digestion. The stomach primarily releases gastric acid, the liver produces bile but stores it in the gallbladder, and the pancreas secretes bicarbonate to neutralize stomach acid in the small intestine. Therefore, choices A, B, and C are incorrect.

4. Why is a pulse oximeter attached to Mr. Dizon's finger?

• A. To determine if the patient's hemoglobin level is low and if he requires a blood transfusion
• B. To check the level of the patient's tissue perfusion
• C. To measure the effectiveness of the patient's anti-hypertensive medications
• D. To detect oxygen saturation of arterial blood before symptoms of hypoxemia develop

Correct answer: D

Rationale: A pulse oximeter is used to detect the oxygen saturation levels in arterial blood before the onset of hypoxemia symptoms. This device provides essential information about the effectiveness of oxygen transportation to the body's tissues. Choice A is incorrect because a pulse oximeter does not directly measure hemoglobin levels nor determine the need for a blood transfusion. Choice B is incorrect because a pulse oximeter is designed specifically to assess oxygen saturation, not tissue perfusion. Choice C is incorrect because a pulse oximeter is not used to measure the efficacy of anti-hypertensive medications, but rather to monitor oxygen levels in the blood.

5. Risk factors that have been shown to contribute to age-related macular degeneration include _____.

• A. oxidative stress from sunlight
• B. iron-deficiency anemia
• C. decreased intake of phytochemicals
• D. vitamin B6 malabsorption

Correct answer: A

Rationale: The correct answer is A: oxidative stress from sunlight. Oxidative stress caused by exposure to sunlight is a significant risk factor for age-related macular degeneration. This condition can result in vision loss among older individuals. Choices B, C, and D are incorrect. Iron-deficiency anemia, decreased intake of phytochemicals, and vitamin B6 malabsorption are not established risk factors for age-related macular degeneration.
