1. A patient has a temperature of 38.5°C. Which Fahrenheit
temperature is closest?
a. 97.7°F
b. 99.5°F
c. 101.3°F
d. 103.8°F
Rationale: To convert Celsius to Fahrenheit, use °F = (°C × 9/5) + 32.
For 38.5°C, the result is approximately 101.3°F, indicating a fever.
2. Which organelle is primarily responsible for producing ATP in a
cell?
a. Ribosome
b. Nucleus
,c. Golgi apparatus
d. Mitochondrion
Rationale: Mitochondria generate most of the cell's ATP through
cellular respiration. ATP provides energy needed for many cellular
processes.
3. Which blood vessel carries oxygenated blood from the lungs to
the heart?
a. Pulmonary artery
b. Superior vena cava
c. Inferior vena cava
d. Pulmonary vein
Rationale: Pulmonary veins carry oxygen-rich blood from the lungs to
the left atrium. Most arteries carry oxygenated blood, but the
pulmonary artery is an important exception.
4. What is the primary function of red blood cells?
a. Produce antibodies
b. Destroy bacteria
c. Form blood clots
d. Transport oxygen
,Rationale: Red blood cells contain hemoglobin, a protein that binds
oxygen in the lungs and transports it to body tissues. They also carry
some carbon dioxide back toward the lungs.
5. Which structure is the functional unit of the kidney?
a. Alveolus
b. Neuron
c. Nephron
d. Sarcomere
Rationale: The nephron is the microscopic functional unit of the
kidney. It filters blood and contributes to the regulation of water,
electrolytes, and waste products.
6. Which part of the digestive system is primarily responsible for
nutrient absorption?
a. Esophagus
b. Stomach
c. Small intestine
d. Large intestine
Rationale: Most digestion and nutrient absorption occur in the small
intestine. Its extensive surface area, including villi and microvilli,
facilitates absorption.
, 7. Which type of blood cell is primarily involved in immune defense?
a. Erythrocyte
b. Platelet
c. Leukocyte
d. Osteocyte
Rationale: Leukocytes, or white blood cells, protect the body against
infection and foreign substances. Different leukocyte types perform
different immune functions.
8. Which chamber of the heart pumps oxygenated blood into
systemic circulation?
a. Right atrium
b. Right ventricle
c. Left atrium
d. Left ventricle
Rationale: The left ventricle pumps oxygenated blood through the
aorta to the systemic circulation. Its muscular wall is thicker than that
of the right ventricle because it generates higher pressure.
9. Which hormone lowers blood glucose levels?
a. Glucagon
b. Cortisol
