Review answer and explanation

Answer: Cerebellum

The cerebellum integrates sensory input to coordinate posture and movement.

2. Which cells form myelin in the peripheral nervous system?
Review answer and explanation

Answer: Schwann cells

Schwann cells insulate peripheral axons and support rapid conduction.

3. Which valve lies between the left atrium and left ventricle?
Review answer and explanation

Answer: Mitral valve

The mitral valve prevents backflow into the left atrium during ventricular contraction.

4. Which vessel carries blood out of the left ventricle?
Review answer and explanation

Answer: Aorta

The aorta distributes blood to the systemic circulation.

5. Which structure prevents food entering the airway during swallowing?
Review answer and explanation

Answer: Epiglottis

The epiglottis helps cover the laryngeal inlet during swallowing.

6. Which cells secrete gastric hydrochloric acid?
Review answer and explanation

Answer: Parietal cells

Parietal cells secrete acid and intrinsic factor; chief cells secrete pepsinogen.

7. Most nutrient absorption occurs in which organ?
Review answer and explanation

Answer: Small intestine

Villi and microvilli provide a large absorptive surface in the small intestine.

8. Which hormone increases water reabsorption in collecting ducts?
Review answer and explanation

Answer: Antidiuretic hormone

ADH increases collecting-duct water permeability, helping conserve water.

9. Which cells build new bone?
Review answer and explanation

Answer: Osteoblasts

Osteoblasts form bone matrix; osteoclasts resorb bone.

Review answer and explanation

Answer: Diaphragm

Review answer and explanation

Answer: Stress score

When examining workload as a predictor of stress, stress is the dependent variable.

15. What does instrument reliability describe?
Review answer and explanation

Answer: Consistency of measurement

Reliability concerns reproducibility or consistency, not necessarily validity.

16. What does validity primarily concern?
Review answer and explanation

Answer: Whether the intended construct is measured

An instrument must measure the construct it claims to assess.

17. Selecting every fifth nurse after a random start is which method?
Review answer and explanation

Answer: Systematic sampling

Systematic sampling uses a fixed interval after a random starting point.

18. Which chart is suitable for comparing numbers across wards?
Review answer and explanation

Answer: Bar chart

Bar heights show differences between discrete categories.

19. What is the mode of 2, 3, 3, 5, 7?
Review answer and explanation

Answer: 3

The mode is the most frequent observation.

20. A correlation of minus 0.70 suggests what relationship?
Review answer and explanation

Answer: A relatively strong inverse association

The negative sign indicates opposite directions; correlation alone cannot establish causation.
