1. _____ neutralizes stomach acid in the small intestine:

• A. saliva
• B. gastric mucus
• C. bicarbonate ions
• D. enzymes

Correct answer: C

Rationale: The correct answer is C: bicarbonate ions. Bicarbonate ions, secreted by the pancreas, neutralize the acidic chyme entering the small intestine from the stomach, creating a more suitable environment for digestive enzymes. Saliva (choice A) helps in the initial breakdown of food in the mouth, not in neutralizing stomach acid. Gastric mucus (choice B) protects the stomach lining from the acidic environment but does not neutralize the acid in the small intestine. Enzymes (choice D) facilitate chemical reactions in digestion but do not neutralize stomach acid.

2. A client receiving total parenteral nutrition (TPN) suddenly develops tremors, dizziness, and diaphoresis. The client said, 'I feel weak and the bag was empty.' Which is the most likely complication the client is currently experiencing?

• A. Fluid volume overload
• B. Sepsis
• C. Hyperglycemia
• D. Hypoglycemia

Correct answer: D

Rationale: The client experiencing tremors, dizziness, diaphoresis, weakness, and stating that the TPN bag is empty is likely experiencing hypoglycemia. Hypoglycemia can occur when the TPN infusion suddenly stops, leading to a rapid drop in blood sugar levels. Symptoms of hypoglycemia include tremors, dizziness, diaphoresis, and weakness. Choices A, B, and C are incorrect as the symptoms presented are more consistent with hypoglycemia rather than fluid volume overload, sepsis, or hyperglycemia.

3. Select all that apply. Which of the following oils contain high levels of unsaturated fatty acids and low levels of saturated and trans fats?

• A. vegetable oil
• B. palm oil
• C. coconut oil
• D. canola oil

Correct answer: A

Rationale: Vegetable, canola, and olive oils are high in unsaturated fats and low in saturated and trans fats, making them heart-healthy choices.

4. People with only one arm or hand may benefit from using a ____ when eating?

• A. dish with suction cups
• B. rocker knife
• C. utensil holder
• D. flexible straw

Correct answer: B

Rationale: A rocker knife is specifically designed for individuals with limited use of one hand or arm, allowing them to cut food easily. This makes it a suitable option for people with only one arm or hand. Choice A, a dish with suction cups, may not directly aid in cutting food with one hand. Choice C, an utensil holder, is not typically used for cutting food. Choice D, a flexible straw, is more related to drinking liquids and not specifically designed to assist in cutting food one-handed.

5. 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.
