1. _____ neutralizes stomach acid in the small intestine:

• A. saliva
• B. gastric mucus
• C. bicarbonate ions
• D. enzymes

Correct answer: C

Rationale: The correct answer is C: bicarbonate ions. Bicarbonate ions, secreted by the pancreas, neutralize the acidic chyme entering the small intestine from the stomach, creating a more suitable environment for digestive enzymes. Saliva (choice A) helps in the initial breakdown of food in the mouth, not in neutralizing stomach acid. Gastric mucus (choice B) protects the stomach lining from the acidic environment but does not neutralize the acid in the small intestine. Enzymes (choice D) facilitate chemical reactions in digestion but do not neutralize stomach acid.

2. 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.

3. Which of the following is a normal finding during assessment of a Chest tube in a 3 way bottle system?

• A. There is a continuous bubbling in the drainage bottle
• B. There is an intermittent bubbling in the suction control bottle
• C. The water fluctuates during inhalation of the patient
• D. There is 3 cm of water left in the water seal bottle

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.

4. What would a diet manual most likely contain?

• A. Procedures for disinfecting cooking surfaces
• B. Staff sanitation guidelines
• C. Information on specific patients' resting metabolic rates
• D. Specific food preparation methods

Correct answer: D

Rationale: A diet manual typically contains guidance on specific food preparation methods to ensure proper nutrition and health for individuals following the diet. Therefore, choice D is correct. Choices A and B refer to sanitation procedures and staff hygiene issues, which are important but not typically the focus of a diet manual. Choice C, regarding specific patients' resting metabolic rates, is too individualized and detailed for a general diet manual, as it would be part of a personalized dietary plan developed with a healthcare professional.

5. Which vitamin deficiency is most likely to cause bleeding disorders?

• A. Vitamin A
• B. Vitamin E
• C. Vitamin K
• D. Vitamin D

Correct answer: C

Rationale: Vitamin K is essential for blood clotting as it plays a crucial role in the activation of clotting factors. Deficiency of Vitamin K can lead to impaired blood clotting, resulting in bleeding disorders. Vitamin A is more associated with vision and skin health, not blood clotting. Vitamin E is known for its antioxidant properties and role in immune function, not specifically related to bleeding disorders. Vitamin D plays a key role in calcium absorption and bone health, but it is not directly linked to blood clotting or bleeding disorders.
