1. What is a disadvantage of using a food frequency questionnaire?

• A. It does not influence the food choices of the consumer
• B. It is not affected by seasonal changes in the diet
• C. It is not effective for monitoring short-term changes in food intake
• D. It does not take too long to obtain the results

Correct answer: C

Rationale: Option C is correct because a food frequency questionnaire is designed to capture a person's typical food intake over an extended period and is not suitable for monitoring short-term changes in diet. The questionnaire's purpose is to provide insights into long-term dietary patterns rather than immediate changes. Option A is incorrect as the questionnaire does not influence food choices; it merely records them. Option B is also incorrect because, while seasonal changes can impact food availability and thereby influence diet, the questionnaire itself is not affected by these changes. Lastly, option D is incorrect as the time to obtain results from a food frequency questionnaire would depend on the respondent's speed and accuracy rather than being intrinsically linked to the questionnaire.

2. Onset frequently occurs after the age of 40.

• A. Type 1 Diabetes
• B. Type 2 Diabetes
• C.
• D.

Correct answer: B

Rationale: The correct answer is B, Type 2 Diabetes. Type 2 Diabetes commonly presents with an onset after the age of 40, although it is now also seen in younger individuals due to lifestyle factors such as poor diet and lack of exercise. Type 1 Diabetes, on the other hand, typically develops in childhood or adolescence and is not associated with age over 40. Choices C and D are left blank as they are not relevant to the question.

3. A nurse is providing nutritional information to a client with osteoporosis. Which food should the nurse recommend as being the highest in calcium?

• A. 1 cup carrot strips
• B. 3 oz canned salmon
• C. 1 plain baked potato
• D. 1 cup chopped chicken breast

Correct answer: B

Rationale: Canned salmon with bones is high in calcium.

4. When observing a return demonstration of a colostomy irrigation, you know that more teaching is required if pt:

• A. Lubricates the tip of the catheter prior to inserting into the stoma
• B. Hangs the irrigating bag on the bathroom door cloth hook during fluid insertion
• C. Discontinues the insertion of fluid after only 500 ml of fluid has been instilled
• D. Clamps of the flow of fluid when felling uncomfortable

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

5. 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.
