1. A nurse is discussing sources of vitamin K with a client. Which food should the nurse recommend?

• A. Fish
• B. Leafy greens
• C. Citrus fruits
• D. Nuts

Correct answer: B

Rationale: Leafy greens are rich in vitamin K, which is important for blood clotting.

2. The psychosocial task of a 55 year old adult client is:

• A. Industry vs. Inferiority
• B. Intimacy vs. Isolation
• C. Integrity vs. Despair
• D. Generativity vs. Stagnation

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. Which vitamin deficiency is most likely to be associated with increased risk of macular degeneration?

• A. Vitamin A
• B. Vitamin B12
• C. Vitamin C
• D. Vitamin E

Correct answer: D

Rationale: Vitamin E is an antioxidant that helps protect eye health and prevent macular degeneration.

5. Which dietary approach is most beneficial for managing hypertension?

• A. Increasing caffeine intake
• B. Reducing sodium intake
• C. Increasing dietary cholesterol
• D. Reducing fiber intake

Correct answer: B

Rationale: Reducing sodium intake is the most beneficial dietary approach for managing hypertension. High sodium intake can lead to increased blood pressure, so lowering sodium intake is crucial in managing hypertension. Choices A, C, and D are incorrect because increasing caffeine intake, dietary cholesterol, or reducing fiber intake are not recommended dietary approaches for managing hypertension and may even have adverse effects on blood pressure levels.
