1. What is the main function of dietary fiber in managing cholesterol levels?

• A. To reduce absorption of dietary fats
• B. To increase cholesterol synthesis
• C. To enhance protein digestion
• D. To decrease cholesterol absorption

2. A breastfeeding mother complains that she missed her son's last two feedings and now her breasts have become full, hard, and uncomfortable. This condition is known as _____.

• A. mastitis
• B. engorgement
• C. letdown
• D. galactorrhea

Correct answer: B

Rationale: Engorgement occurs when the breasts become overly full, leading to discomfort and sometimes difficulty with latching. It can be relieved by feeding or expressing milk. Mastitis, choice A, is characterized by breast inflammation usually caused by an infection. Letdown, choice C, refers to the release of milk from the breast. Galactorrhea, choice D, is the spontaneous flow of milk from the breast unassociated with childbirth or nursing.

3. What does a QRS Complex represent in an ECG reading?

• A. Atrial depolarization
• B. Ventricular repolarization
• C. Ventricular depolarization
• D. End of ventricular depolarization

Correct answer: C

Rationale: The QRS Complex in an ECG reading represents ventricular depolarization, which is the process of the heart's ventricles preparing to contract by changing the electrical charge in the cell, hence choice 'C' is the correct answer. Choice 'A' is incorrect because atrial depolarization is represented by the P wave in an ECG reading, not the QRS Complex. Choice 'B' is incorrect as ventricular repolarization is depicted by the T wave, not the QRS Complex. Finally, choice 'D' is also incorrect because the QRS Complex is not the end of ventricular depolarization, but the process itself.

4. Amy is a 68-year-old patient who has rheumatoid arthritis affecting her hands and feet. Which substance has been shown to reduce joint tenderness and improve mobility in some people with this type of arthritis?

• A. Alfalfa Tea
• B. Cod Liver Oil
• C. Lecithin
• D. Fish Oil

Correct answer: D

Rationale: Fish oil has been identified as a substance that can help reduce joint tenderness and improve mobility in individuals with rheumatoid arthritis, as it is rich in omega-3 fatty acids. Omega-3 fatty acids have anti-inflammatory properties that can help alleviate the symptoms of rheumatoid arthritis. On the other hand, while Alfalfa Tea, Cod Liver Oil, and Lecithin have various health benefits, there isn't substantial evidence to suggest that they can improve conditions associated with rheumatoid arthritis.

5. A healthcare provider is teaching a client about nutritional requirements necessary to promote wound healing. Which of the following nutrients should the provider include in the teaching?

• A. Protein
• B. Calcium
• C. Vitamin B1
• D. Vitamin D

Correct answer: A

Rationale: Protein is crucial for wound healing as it plays a vital role in tissue repair and synthesis. Calcium is important for bone health but not directly related to wound healing. Vitamin B1 is essential for energy production but not specifically significant for wound healing. Vitamin D is essential for bone health and immune function but is not a primary nutrient emphasized for wound healing.
