1. What laboratory value would be considered a high-risk measure for coronary heart disease assessment?

A. triglycerides > 150 mg/dL
B. BMI > 31
C. LDL cholesterol < 128 mg/dL
D. blood pressure of 128/82 mmHg

Correct answer: B

Rationale: The correct answer is B: BMI > 31. A BMI over 31 is considered a high-risk factor for coronary heart disease as it indicates obesity, which is strongly linked to cardiovascular issues. Triglycerides > 150 mg/dL (choice A) can contribute to heart disease risk but are not as specific as BMI in assessing overall risk. LDL cholesterol < 128 mg/dL (choice C) is actually a desirable level, indicating lower risk. A blood pressure of 128/82 mmHg (choice D) is within normal range and not a high-risk measure specifically for coronary heart disease.

2. 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.

3. What is the first step in decontamination?

A. Immediately applying a chemical decontamination foam to the area of contamination
B. Thoroughly washing and rinsing the patient with soap and water
C. Immediately applying personal protective equipment
D. Removing the patient's clothing and jewelry, then rinsing the patient with water

Correct answer: D

Rationale: The correct first step in decontamination is to remove the patient's clothing and jewelry to prevent further exposure and then rinse the patient with water. This helps to eliminate any contaminants on the patient's body. Choice A is incorrect because applying a chemical decontamination foam should come after removing clothing. Choice B is incorrect as washing and rinsing the patient should follow the removal of clothing. Choice C is incorrect as personal protective equipment should be worn by the individual performing the decontamination, not applied to the patient.

4. A diet high in which nutrient can lead to increased risk of developing kidney stones?

A. Fiber
B. Protein
C. Carbohydrates
D. Unsaturated fats

Correct answer: B

Rationale: High protein intake can increase the risk of kidney stones due to elevated calcium excretion.

5. Which of the following groups of vitamins are fat-soluble?

A. vitamins B and C
B. vitamins A and C
C. vitamins B, E, K, D
D. vitamins A, E, K, D

Correct answer: D

Rationale: The correct answer is D: vitamins A, E, K, and D. Fat-soluble vitamins are absorbed along with fats in the diet and can be stored in the body's fatty tissue. Vitamins B and C are water-soluble vitamins and are not stored in the body; any excess amounts are usually excreted in the urine. Therefore, choices A, B, and C are incorrect.
