1. Recognize the opposing muscle pair.
- A. Bicep and tricep (Arm flexion and extension)
- B. Hamstring and quadriceps (Knee extension and flexion)
- C. Pectoralis major and pectoralis minor (Chest muscles)
- D. Trapezius and deltoid (Shoulder movement)
Correct answer: A
Rationale: The bicep and tricep muscles are antagonistic muscle pairs, meaning they work in opposition to each other. The bicep is located on the front of the upper arm and is responsible for flexing the elbow joint. The tricep is located on the back of the upper arm and is responsible for extending the elbow joint.
2. The main function of the large intestine is:
- A. Digesting and absorbing nutrients
- B. Storing and mixing food
- C. Breaking down carbohydrates
- D. Absorbing water and electrolytes
Correct answer: D
Rationale: The correct answer is D: Absorbing water and electrolytes. The main function of the large intestine is to absorb any remaining water and electrolytes from the indigestible food matter that passes through it. This absorption process helps in forming solid waste (feces) and regulating the body's fluid balance. It is not primarily responsible for digesting and absorbing nutrients like the small intestine, storing and mixing food like the stomach, or breaking down carbohydrates. Understanding the role of the large intestine in water and electrolyte absorption is crucial for maintaining proper digestion and overall health.
3. Which of the following is TRUE about functional nursing?
- A. Concentrates on tasks and activities
- B. Emphasizes use of group collaboration
- C. One-to-one nurse-patient ratio
- D. Provides continuous, coordinated and comprehensive nursing services
Correct answer: B
Rationale: The correct answer is B: "Emphasizes use of group collaboration." Functional nursing is a task-oriented approach where team members specialize in specific tasks or activities. In this model, nurses work together in groups to provide care to a larger number of patients efficiently. This differs from the one-to-one nurse-patient ratio (C) and the continuous, coordinated, and comprehensive nursing services (D). While functional nursing concentrates on tasks (A), the key feature emphasized in this care delivery model is the use of group collaboration to provide care effectively.
4. What is the scientific term for a broken bone?
- A. Osteoporosis
- B. Fracture
- C. Sprain
- D. Dislocation
Correct answer: B
Rationale: The correct answer is B: 'Fracture.' A fracture is the scientific term used to describe a broken bone. Osteoporosis (A) is a condition where bones become weak and brittle, increasing the risk of fractures. A sprain (C) is an injury to a ligament, not a bone. A dislocation (D) occurs when the bones in a joint are forced out of their normal position, but it is not the term for a broken bone.
5. A lab test result shows a blood glucose level of 5.5 millimoles per liter (mmol/L). What is the equivalent level in milligrams per deciliter (mg/dL)?
- A. 55 mg/dL
- B. 5.5 mg/dL
- C. 0.55 mg/dL
- D. 550 mg/dL
Correct answer: A
Rationale: This requires a double conversion: millimoles to milligrams and liters to deciliters. 1 millimole is equal to 180.15 milligrams, and 1 liter is equal to 10 deciliters. Multiply the glucose level (5.5 mmol/L) by the conversion factor for millimoles to milligrams (180.15 mg/mmol) and then divide by the conversion factor for liters to deciliters (10 dL/L): 5.5 mmol/L * 180.15 mg/mmol / 10 dL/L ≈ 55 mg/dL.
6. The K-capture process, a type of electron capture, involves the capture of an electron from which electron shell:
- A. The outermost s-orbital
- B. An inner p-orbital
- C. An inner d-orbital
- D. Any available electron shell
Correct answer: A
Rationale: The K-capture process involves the capture of an electron from the innermost electron shell, known as the K-shell. The K-shell is represented by the outermost s-orbital in an atom's electron configuration. When an electron from the K-shell is captured, it results in the transition of a proton to a neutron in the nucleus, thereby changing the atomic number of the element. Therefore, option A, 'The outermost s-orbital,' is the correct answer as it accurately describes the electron shell involved in the K-capture process.
