1. Which two dietary components may help decrease blood cholesterol levels?

• A. Omega-3 fatty acids and soluble fiber
• B. Short-chain fatty acids and insoluble fiber
• C. Trans fatty acids and potassium
• D. Cis fatty acids and calcium

Correct answer: A

Rationale: The correct answer is A: Omega-3 fatty acids and soluble fiber. Omega-3 fatty acids are known to reduce triglycerides, while soluble fiber helps to lower LDL cholesterol levels. Both of these components are beneficial in managing blood cholesterol levels. Choice B, short-chain fatty acids and insoluble fiber, is incorrect as they do not have the same cholesterol-lowering effects as omega-3 fatty acids and soluble fiber. Choice C, trans fatty acids and potassium, is incorrect as trans fatty acids can raise LDL cholesterol levels and increase the risk of heart disease. Choice D, cis fatty acids and calcium, is incorrect as cis fatty acids are common in natural fats and do not specifically help in reducing blood cholesterol levels.

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 end product of lipid digestion?

• A. fatty acid
• B. sucrose
• C. monosaccharide
• D. amino acid

Correct answer: A

Rationale: The correct answer is A, fatty acid. During the process of lipid digestion, triglycerides are broken down into fatty acids and glycerol. These end products are then absorbed into the bloodstream or lymphatic system for further processing. Choices B, C, and D are incorrect because sucrose is a disaccharide, monosaccharide is a simple sugar unit, and amino acid is a building block of proteins, not the end product of lipid digestion.

4. Which type of medication is most likely to induce xerostomia?

• A. Antibiotics
• B. Diuretics
• C. Local anesthetics
• D. Anticholinergics

Correct answer: D

Rationale: The correct answer is D, Anticholinergics. Anticholinergic medications commonly cause xerostomia by inhibiting saliva production, leading to dry mouth. Antibiotics (choice A) are not typically associated with xerostomia. Diuretics (choice B) increase urine production but do not directly affect saliva production. Local anesthetics (choice C) are used to numb specific areas during dental procedures and do not induce xerostomia.

5. A nurse is teaching an in-service about manifestations of hypoglycemia to a group of newly licensed nurses. Which of the following should the nurse include in the teaching?

• A. Blurred vision
• B. Vomiting
• C. Kussmaul respirations
• D. Bradycardia

Correct answer: A

Rationale: Corrected Rationale: Blurred vision is a common symptom of hypoglycemia and should be included in the teaching. Other manifestations like vomiting, Kussmaul respirations, and bradycardia are not typically associated with hypoglycemia. Vomiting is more commonly seen in conditions like food poisoning or gastrointestinal issues. Kussmaul respirations are deep and rapid respirations seen in metabolic acidosis, not hypoglycemia. Bradycardia is usually not a manifestation of hypoglycemia; tachycardia is more commonly associated with low blood sugar levels.
