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. Surgery schedules are communicated to the OR usually a day prior to the procedure by the nurse of the floor or ward where the patient is confined. For orthopedic cases, what department is usually informed to be present in the OR?

• A. Rehabilitation department
• B. Laboratory department
• C. Maintenance department
• D. Radiology department

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.

3. How is the equalization of solute concentration of intracellular fluids (ICFs) and extracellular fluids (ECFs accomplished?

• A. Semipermeable membranes.
• B. Hydration.
• C. Osmotic pressure.
• D. Perspiration.

Correct answer: C

Rationale: The correct answer is C, osmotic pressure. Osmotic pressure within the body equalizes the solute concentration of ICFs and ECFs by shifting small amounts of water in the direction of higher concentration solute. Semipermeable membranes separate one fluid compartment from another and do not directly equalize solute concentrations. Hydration and perspiration are important elements of fluid balance but do not directly achieve the equalization of solute concentrations between ICFs and ECFs, which is primarily regulated by osmotic pressure.

4. Which nursing diagnosis has nutritional implications?

• A. impaired dentition
• B. disruption of gas exchange
• C. self-esteem disturbance
• D. sleep pattern disturbance

Correct answer: A

Rationale: Impaired dentition affects a patient's ability to chew and consume a variety of foods, leading to potential nutritional deficiencies and malnutrition.

5. What is a major goal for home care nurses?

• A. Restoring maximum health function.
• B. Promoting the health of populations.
• C. Minimizing the progress of disease.
• D. Maintaining the health of populations.

Correct answer: A

Rationale: A major goal for home care nurses is restoring maximum health function. This involves helping patients achieve their highest level of health and independence, focusing on individualized care plans tailored to each patient's needs. Choice B, promoting the health of populations, is more aligned with public health nursing rather than home care nursing. Choice C, minimizing the progress of disease, is important but not as comprehensive as restoring maximum health function. Choice D, maintaining the health of populations, is more about preventive care at a population level rather than the individualized care provided by home care nurses.
