1. How many amino acids are essential?

• A. 5
• B. 7
• C. 9
• D. 13

Correct answer: C

Rationale: The correct answer is C: 9. There are 9 essential amino acids that the body cannot synthesize and must be obtained through the diet. These 9 amino acids are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine. Choices A, B, and D are incorrect as they do not represent the correct number of essential amino acids.

2. Mario listens to Richard’s bilateral sounds and finds that congestion is in the upper lobes of the lungs. The appropriate position to drain the anterior and posterior apical segments of the lungs when Mario does percussion would be:

• A. Client lying on his back then flat on his abdomen on Trendelenburg position
• B. Client seated upright in bed or on a chair then leaning forward in sitting position then flat on his back and on his
• C. Client lying flat on his back and then flat on his abdomen
• D. Client lying on his right then left side on Trendelenburg position

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.

3. A nurse is teaching a client who needs to increase their daily fluid intake. Which of the following foods has the highest percentage of water by weight?

• A. Yogurt
• B. Milk
• C. Lettuce
• D. Honey

Correct answer: C

Rationale: The correct answer is Lettuce. Lettuce has the highest percentage of water by weight among the options provided, making it an excellent choice to increase fluid intake. Yogurt and milk have some water content but are not as high in water percentage as lettuce. Honey, on the other hand, contains very little water and is not a good choice for increasing fluid intake.

4. 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.

5. Which mineral is essential for wound healing?

• A. iodine
• B. chromium
• C. zinc
• D. sulfate

Correct answer: C

Rationale: Zinc plays a critical role in wound healing due to its involvement in cell proliferation, immune function, and protein synthesis, all of which are essential for tissue repair.
