Q001: During a laboratory session on the cardiovascular system, you are
examining a preserved sheep heart. Your instructor asks you to identify the
structure that separates the left and right ventricles on the external surface. You
observe a deep groove filled with fat and coronary vessels running vertically down
the heart. Which structure are you identifying?
Options:
A. Interventricular septum
B. Anterior interventricular sulcus
C. Coronary sulcus
D. Ligamentum arteriosum
ANSWER: B
Q002: In the physiology lab, your group is recording a Lead II ECG from a
volunteer. You observe a clear P wave followed by a QRS complex and T wave.
Your lab partner asks you to measure the PR interval. Using the standard paper
speed of 25 mm/sec, you count 4 small squares from the beginning of the P wave
to the beginning of the QRS. What is the correct measurement?
Options:
A. 0.08 seconds
B. 0.16 seconds
C. 0.20 seconds
D. 0.24 seconds
, 2
ANSWER: B
Q003: You are using a sphygmomanometer to measure blood pressure in a lab
partner. You inflate the cuff to 180 mmHg and slowly release the pressure. At 120
mmHg, you hear the first Korotkoff sound. At 78 mmHg, the sounds completely
disappear. How should you correctly document this reading according to AHA
guidelines?
Options:
A. 78/120 mmHg
B. 120/78 mmHg
C. 180/78 mmHg
D. 120/180 mmHg
ANSWER: B
Q004: In the respiratory physiology lab, you are performing spirometry on a
healthy subject. The recorded value for forced vital capacity (FVC) is 4.2 L, and
forced expiratory volume in 1 second (FEV1) is 3.5 L. What is the calculated
FEV1/FVC ratio, and is it within normal limits?
Options:
A. 0.75 (75%) - abnormal
B. 0.83 (83%) - normal
C. 0.65 (65%) - obstructive pattern
D. 0.90 (90%) - restrictive pattern
ANSWER: B
Q005: You are examining a microscope slide of a cross-section through the
trachea. You observe rings of hyaline cartilage, pseudostratified ciliated columnar
epithelium, and mucous glands in the submucosa. Which cellular structure is
responsible for moving mucus and trapped particles upward toward the pharynx?
Options:
, 3
A. Microvilli on columnar cells
B. Cilia on the apical surface of epithelial cells
C. Goblet cell secretions
D. Basal cell mitosis
ANSWER: B
Q006: During a lab on endocrine anatomy, you are identifying structures on a
dissected cat specimen. You locate a small, bilobed gland on the posterior surface
of the thyroid gland. The gland has two oval lobes resembling small peas. Which
endocrine organ are you identifying?
Options:
A. Thymus gland
B. Parathyroid glands
C. Thyroid isthmus
D. Accessory spleen
ANSWER: B
Q007: In the renal physiology experiment, you are analyzing a urine sample. The
sample tests positive for glucose using the dipstick method. You confirm the
presence of glucose in the urine by performing a Clinitest tablet reaction that
produces a green color. What is the correct term for glucose in the urine, and what
is the renal tubular transport maximum that has been exceeded?
Options:
A. Glycosuria; transport maximum for amino acids
B. Glycosuria; renal threshold for glucose reabsorption (approximately 180 mg/dL)
C. Ketonuria; transport maximum for ketones
D. Proteinuria; glomerular filtration barrier
ANSWER: B
