Nursing Elites

1. Each statement is true of swallowing and processing food, except one. Which is the exception?

• A. The swallowing reflex moves a bolus into the esophagus
• B. A bolus is a mass of food
• C. The bolus is transported to the stomach by osmosis and gravity
• D. The bolus penetrates the diaphragm through the esophageal hiatus

Correct answer: C

Rationale: The correct answer is C. The bolus is not transported to the stomach by osmosis and gravity, but by peristalsis. Peristalsis is the involuntary constriction and relaxation of muscles to push the bolus through the digestive system. Choices A, B, and D are correct statements. A bolus is indeed a mass of food, the swallowing reflex does move the bolus into the esophagus, and the bolus does not penetrate the diaphragm through the esophageal hiatus; instead, it enters the stomach through the lower esophageal sphincter.

2. The substance that is most supportive of bones and teeth is:

• A. Hemoglobin
• B. Collagen
• C. Insulin
• D. Pepsin

Correct answer: B

Rationale: Collagen is a key structural protein in bones and teeth, providing support and strength.

3. During operation, who manages the lighting, noise, temperature and other factors in the operating room suite?

• A. Nurse Supervisor
• B. Surgeon
• C. Circulating Nurse
• D. Scrub Nurse

Correct answer: C

Rationale: In an operating room, the circulating nurse is responsible for managing environmental factors such as lighting, noise, and temperature. This role includes ensuring the comfort and safety of the patient, as well as the efficiency of the team. While the Nurse Supervisor, Surgeon, and Scrub Nurse also have crucial roles during an operation, they do not directly manage the environmental conditions of the operating room. The rationale provided does not directly address the question asked, and appears to relate more to the broader role of nursing in patient care.

4. The Acceptable Macronutrient Distribution Ranges state that half of your calories should come from protein.

• A. TRUE
• B. FALSE
• C.
• D.

Correct answer: B

Rationale: The statement is FALSE. The Acceptable Macronutrient Distribution Ranges recommend that 10-35% of daily calories come from protein, not half. The remaining calories should be derived from a combination of carbohydrates and fats to ensure a balanced diet. Choosing option A is incorrect because it misinterprets the recommended percentage for protein intake. Options C and D are left blank as they are not applicable to the question.

5. Any disease that produces ____ malabsorption can bring about deficiencies of vitamins A, D, E, and K.

• A. water
• B. protein
• C. fat
• D. carbs

Correct answer: C

Rationale: Vitamins A, D, E, and K are fat-soluble, meaning they require fat for absorption. Diseases that cause fat malabsorption can lead to deficiencies in these vitamins.
