Question 5

The MOST important factor that determines the percent of oxygen saturation of hemoglobin is A)red blood count B)volume of the blood C)P_O2 D)heart rate E)P_CO2

Accepted Answer

The sequence of oxygen and hemoglobin binding and releasing is determined by the partial pressure of oxygen in the blood, and is described by the oxygen-hemoglobin dissociation curve. This sequence determines the percent of oxygen saturation of hemoglobin. Choice C represents the correct sequence of oxygen and hemoglobin binding and releasing, which is essential for oxygen transport in the body.

Question 8

What is E pointing to?

A)Soft palate
B)Ethmoid bone
C)Hard palate
D)Nasal septum
E)Air cells

Accepted Answer

The code "11ea7f55_b91e_7507_9ecd_b91b8b2d2536_TB6091_00" appears to be a medical or anatomical reference. However, without further context, it is impossible to determine what it refers to. Therefore, none of the anatomical structures listed (soft palate, ethmoid bone, hard palate, air cells) can be definitively identified as what E is pointing to.

Question 9

A White baby boy is born after 7 months of gestation.He develops difficulty breathing and looks slightly blue.He is most likely suffering from
A)the flu
B)bacterial pneumonia
C)asthma
D)respiratory distress syndrome (RDS)
E)viral pneumonia

Accepted Answer

The symptoms of difficulty breathing and bluish discoloration suggest a respiratory problem. Respiratory distress syndrome (RDS) is commonly seen in premature babies, especially those born before 37 weeks of gestation. It is caused by a lack of surfactant, a substance that helps the lungs expand and function properly. Babies with RDS may require oxygen therapy and other supportive treatments to manage their breathing difficulties.

Question 10

Where is the uvula?

A)E
B)F
C)Q
D)S
E)U

Question 11

An individual suffers a blood clot in an artery that delivers blood to his leg.The leg begins to take on a blue hue,becomes colder than the rest of his body and he experiences numbness in the leg.He is most likely experiencing
A)anemic hypoxia
B)ischemic hypoxia
C)hypoxic hypoxia
D)histotoxic hypoxia
E)allergic hypoxia

Accepted Answer

The description suggests that the individual is experiencing ischemic hypoxia, which occurs when there is a decreased blood flow to a body part leading to inadequate oxygen supply. The blue hue, coldness and numbness result from the lack of oxygen and nutrients to the tissues in the affected area. Anemic hypoxia is caused by a decrease in the oxygen-carrying capacity of the blood, hypoxic hypoxia results from a lack of oxygen in the air, histotoxic hypoxia is caused by the inability of cells to use oxygen despite adequate supply, and allergic hypoxia is caused by an allergic reaction leading to airway obstruction and decreased oxygen supply.

Question 12

Which of the following is a factor that does NOT affect hemoglobin's affinity for oxygen?
A)pH of blood
B)Partial pressure of the oxygen
C)Amount of oxygen available
D)Temperature
E)Respiratory rate

Accepted Answer

Respiratory rate does not directly affect hemoglobin's affinity for oxygen. Factors like pH of blood, partial pressure of oxygen, amount of oxygen available, and temperature directly influence how readily hemoglobin binds to or releases oxygen. Respiratory rate, however, affects the amount of oxygen entering the lungs and the removal of carbon dioxide but does not directly alter hemoglobin's oxygen-binding properties.

Question 13

Where is the inferior nasal concha?

A)A
B)B
C)C
D)D
E)E

Accepted Answer

The answer of Where is the inferior nasal concha?

A)A
B)B

Question 14

An individual is suffering from gangrene.This is a condition where circulation to tissues is interrupted causing a serious reduction in oxygenation to these tissues.Anaerobic bacteria invade the tissues and must be treated.If antibiotics don't work,an intelligent treatment may include
A)hyperbaric oxygenation
B)fresh air
C)drinking liquids with alcohol
D)a reduction in ambient oxygen levels
E)all of these are valid treatments

Accepted Answer

Hyperbaric oxygenation involves the administration of high oxygen concentrations at high pressures which increases the amount of oxygen delivered to the tissues. This can help treat gangrene by stimulating growth of new blood vessels and enhancing the destruction of anaerobic bacteria. Fresh air or reduction in ambient oxygen levels offer little benefit, and drinking alcohol can worsen the condition by further reducing circulation to affected tissues.

Question 15

A man is found lying unconscious on the floor of his apartment during a very cold period.A space heater is nearby.His lips appear to be cherry red in color.He might be suffering from
A)carbon dioxide poisoning
B)sulfur dioxide poisoning
C)carbon monoxide poisoning
D)excessive oxygen intake
E)any of these is possible

Accepted Answer

The cherry red coloration of the man's lips suggest carbon monoxide poisoning, which is a common issue during cold periods when people use space heaters or other types of heating equipment. Carbon monoxide can build up and cause poisoning, leading to symptoms such as unconsciousness and cherry red lips. The other options (A, B, D) are less likely causes for the symptoms described.

Question 16

A)A
B)C
C)T
D)U
E)V

Accepted Answer

The nasal conchae, also known as nasal turbinates, are bony structures located inside the nasal cavity that help to warm, moisturize, and filter incoming air. Choice B shows the correct location of the nasal conchae on the labeled image.
