1. 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.

2. This study, which is an in-depth study of one boy, is a:

• A. case study
• B. longitudinal study
• C. cross-sectional study
• D. evaluative study

Correct answer: A

Rationale: The correct answer is 'A: case study.' A case study involves an in-depth examination of a single individual, group, or event. In this scenario, focusing on one boy aligns with the definition of a case study. The other options are not applicable: B) A longitudinal study involves following subjects over a period of time, C) A cross-sectional study examines a population at a single point in time, and D) An evaluative study assesses the effectiveness of a program or intervention, which is not the focus of the given scenario.

3. An essential nutrient must:

• A. be eaten every day
• B. be obtained by the diet
• C. be water soluble
• D. be eaten at every meal

Correct answer: B

Rationale: The correct answer is B: 'be obtained by the diet.' Essential nutrients are those that the body cannot synthesize in sufficient quantities and must therefore be obtained through the diet. Choice A is incorrect because not all essential nutrients need to be consumed daily; the frequency of consumption varies. Choice C is incorrect because not all essential nutrients are water-soluble; they can be water-soluble or fat-soluble. Choice D is incorrect because essential nutrients do not need to be consumed at every meal, but rather need to be included in the overall diet regularly.

4. A nurse is providing teaching to a group of older adults about sources of complete and incomplete protein. Which of the following foods should the nurse include as a complete protein?

• A. Yogurt
• B. Fresh vegetables
• C. Nuts
• D. Dried Beans

Correct answer: A

Rationale: Yogurt is the correct answer as it is a complete protein source, containing all nine essential amino acids. Fresh vegetables, nuts, and dried beans are incomplete protein sources as they lack one or more essential amino acids required by the body.

5. A healthcare provider is admitting a client who practices Hinduism. The healthcare provider should identify that which of the following foods is prohibited according to Hindu dietary practices?

• A. Pork
• B. Chicken
• C. Beef
• D. Seafood

Correct answer: C

Rationale: In Hindu dietary practices, beef is prohibited due to religious beliefs. Hindus consider cows to be sacred animals, and therefore consuming beef is strictly forbidden. Pork, chicken, and seafood are not prohibited in Hindu dietary practices, making choices A, B, and D incorrect.
