1. Which is NOT a characteristic or function of lipids?

A. Involved in energy metabolism and storage
B. Provide insulation and protection
C. Act as hormones that regulate the body
D. Are hydrophilic

Correct answer: D

Rationale: Lipids are known for several functions including involvement in energy metabolism and storage (Choice A), providing insulation and protection (Choice B), and acting as hormones that regulate the body (Choice C). However, lipids are not hydrophilic (water-attracting), contrary to choice D. They are actually hydrophobic, meaning they repel water and do not mix well with it. This is a key property that differentiates them from many other biological molecules.

2. A nurse should be cognizant that professional programs for specialty certification by the Board of Nursing accredited through the:

A. Professional Regulation Commission
B. Nursing Specialty Certification Council
C. Association of Deans of Philippine Colleges of Nursing
D. Philippine Nurse Association

Correct answer: A

Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.

3. Which food is recommended for a client trying to increase their intake of calcium?

A. Apples
B. Yogurt
C. Chicken
D. Pasta

Correct answer: B

Rationale: Yogurt is high in calcium, which is essential for bone health.

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. Which of the following statements are true about iron?

A. The iron needs of vegans are 20% higher, and the needs of endurance athletes are 10% lower.
B. It is one of the most common nutrient deficiencies in the world.
C. Its absorption is increased by Vitamin C and during pregnancy.
D. Its absorption is increased by tannic acid and calcium in milk.

Correct answer: C

Rationale: Choice C is correct because iron absorption is indeed increased by Vitamin C and during pregnancy. The other choices are incorrect. Choice A is wrong as there are no universally accepted percentages for the iron needs of vegans and endurance athletes. Choice B is inaccurate as iron deficiency is actually one of the most common nutritional deficiencies worldwide. Choice D is incorrect because tannic acid and calcium in milk actually inhibit iron absorption rather than increasing it.
