1. What is the fossa ovalis in a fetus?
A chamber of the heart
A structure that aids in fetal respiration
A valve that regulates blood flow
A remnant of the foramen ovale
2. What are the three main phases of an action potential?
Depolarization, Repolarization, Hyperpolarization
Threshold, Action potential, Refractory period
Resting potential, Action potential, Recovery phase
Sodium influx, Potassium efflux, Resting state
3. What do P waves indicate in an electrocardiogram?
Atrial repolarization
Atrial depolarization
Ventricular repolarization
Ventricular depolarization
4. In a scenario where a patient has a compromised immune system, which cell
type's reduced function would most likely impair the body's ability to clear
infections through phagocytosis?
T-cell
B-cell
, Neutrophil
Macrophage
5. A bolus is:
A medical device for administering medication
A type of nutrient absorbed in the intestines
A ball-like mixture of food and saliva formed in the mouth
A digestive enzyme in the stomach
6. If a patient suffers damage to the cerebellum, what specific functions might
be impaired?
Memory and reasoning
Sensory processing and perception
Coordination and balance
Breathing and heart rate
7. The two lower chambers, which pump blood out of the heart, are the _.
atria
aortas
ventricles
valves
8. Describe the role of macrophages in the immune response and how their
phagocytic properties contribute to this role.
Macrophages are responsible for the production of red blood cells.
, Macrophages produce antibodies to neutralize pathogens.
Macrophages primarily function in the clotting process.
Macrophages engulf and digest pathogens and debris, playing a
crucial role in the immune response.
9. A 28-year-old G3 P1011 at 38 weeks GA is 6cm, 100% effaced, and at 0 station.
Which of the following best describes the stage of labor present?
Third stage of labor
Second stage of labor
First stage of labor, latent phase
First stage of labor, active phase
10. Systole corresponds to
heart relaxation
heart contraction
11. Which brain region is primarily associated with the storage and retrieval of
memories?
Amygdala
Cerebellum
Hippocampus
Thalamus
12. What physiological response occurs to regulate blood flow to the kidneys
during an emergency?
Vasoconstriction of renal blood vessels
, Increased heart rate
Vasodilation of renal blood vessels
Increased blood volume
13. Describe the function of the integration center in the context of a reflex arc.
The integration center connects sensory and motor neurons without
processing information.
The integration center receives sensory input and determines the
necessary motor output to elicit a reflex action.
The integration center is responsible for generating action potentials
in sensory neurons.
The integration center transmits sensory information directly to the
brain.
14. The figure below shows two types of nephrons found in mammals. Which
one is important for producing urine with high osmolarity?
Juxtamedullary nephron
Both nephrons can produce high osmolarity urine
