1. Which biomolecule is responsible for the storage and transfer of genetic information?

• A. Carbohydrates
• B. Proteins
• C. Lipids
• D. Nucleic acids

Correct answer: D

Rationale: Nucleic acids, such as DNA and RNA, are the biomolecules responsible for storing and transferring genetic information within cells. Carbohydrates, proteins, and lipids do not have this specific function. Carbohydrates are mainly used for energy storage, structural support, and cellular communication. Proteins are involved in various cellular functions such as enzymatic reactions, structural support, and signaling. Lipids play roles in energy storage, cell membrane structure, and signaling.

2. 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.

3. Fat-soluble vitamins are different from water-soluble vitamins because the body is able to store only small amounts of fat-soluble vitamins.

• A. Both the statement and the reason are correct and related.
• B. Both the statement and the reason are correct but are not related.
• C. The statement is correct, but the reason is not correct.
• D. The statement is not correct, but the reason is correct.

Correct answer: C

Rationale: The statement is correct, but the reason is not correct. A major difference between fat-soluble and water-soluble vitamins is that the body is able to store larger amounts of fat-soluble vitamins. Vitamins A and D are stored for long periods; therefore, minor shortages might not be identified until drastic depletion has occurred. Observable signs and symptoms of a dietary deficiency are often not identified until they are in an advanced state. Water-soluble vitamins, on the other hand, are not stored in the body and are excreted in the urine if taken in excess, making it harder to reach toxic levels.

4. You are caring for Conrad who has a brain tumor and increased Intracranial Pressure (ICP). Which intervention should you include in your plan to reduce ICP?

• A. Administer bowel softener
• B. Position Conrad with his head turned toward the side of the tumor
• C. Provide sensory stimulation
• D. Encourage coughing and deep breathing

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. In taking the client’s blood pressure, the nurse should position the client’s arm:

• A. At the level of the heart
• B. Slightly above the level of the heart
• C. At the 5th intercostals space midclavicular line
• D. Below the level of the heart

Correct answer: A

Rationale: Proper patient positioning is essential for maximizing lung expansion and promoting the drainage of secretions. Postural drainage techniques rely on gravity to help clear different lung segments, which is critical in preventing complications such as atelectasis or pneumonia in immobilized patients.
