1. Which food has the highest calcium content?

• A. soy products
• B. milk
• C. cereal grains
• D. dark green vegetables

Correct answer: B

Rationale: The correct answer is B, milk. Milk is known for being one of the best dietary sources of calcium, essential for bone health and various bodily functions. Soy products, cereal grains, and dark green vegetables are good sources of calcium as well, but milk generally has a higher calcium content compared to these options.

2. The term associated with loss of taste is:

• A. Xerostomia
• B. Hypogeusia
• C. Dysphagia
• D. Anosmia

Correct answer: B

Rationale: The correct answer is B, 'Hypogeusia.' Hypogeusia refers to a diminished sense of taste, which can impact nutritional intake, especially in older adults. Xerostomia (choice A) is dry mouth, Dysphagia (choice C) is difficulty swallowing, and Anosmia (choice D) is the loss of the sense of smell. These conditions are different from loss of taste, making them incorrect choices for this question.

3. What would you do to increase the amount of iron absorbed from a meal?

• A. Drink plenty of coffee before each meal
• B. Avoid eating foods rich in vitamin C with the meal
• C. Eat a calcium-rich food with the meal
• D. Consume orange juice as a beverage with a meal

Correct answer: D

Rationale: The correct answer is D: 'Consume orange juice as a beverage with a meal'. This is because Vitamin C significantly enhances the absorption of non-heme iron, a form of iron found in plant-based foods. Therefore, consuming orange juice, which is rich in vitamin C, with a meal can effectively increase iron absorption. On the contrary, choices A, B, and C are incorrect. Coffee (Choice A) contains polyphenols that can inhibit iron absorption. Avoiding vitamin C-rich foods (Choice B) would decrease iron absorption, not increase it. While calcium (Choice C) is essential for many bodily processes, it can actually inhibit iron absorption when consumed together.

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. The recommended daily fluid intake of patients maintained using hemodialysis is:

• A. 150 mL plus the volume of urinary output
• B. 500 mL plus the volume of urinary output
• C. 1000 mL plus the volume of urinary output
• D. 1500 mL plus the volume of urinary output

Correct answer: C

Rationale: The correct answer is C: 1000 mL plus the volume of urinary output. Fluid intake is typically restricted in hemodialysis patients to prevent fluid overload. The recommended daily fluid intake for these patients is 1000 mL plus any urinary output. Choice A (150 mL plus the volume of urinary output) is too low and would not provide enough fluid for these patients. Choice B (500 mL plus the volume of urinary output) is also insufficient. Choice D (1500 mL plus the volume of urinary output) is too high and may lead to fluid overload in hemodialysis patients.
