Answer:

The correct answer is a. greater than

Explanation:

The partial pressure of oxygen in alveolus is greater than partial pressure of oxygen in deoxygenated blood in a pulmonary capillary and this concentration difference is important for the movement of air(oxygen) from the alveolus to the pulmonary capillary because gases move from higher concentration to lower concentration.

By this process the oxygenated blood reaches to the heart from lungs and heart then pump this oxygenated blood to other body tissues.The partial pressure of oxygen in alveolus is 104 mmHg and in venus blood is 40 mmHg.

a client's holter monitor strip reveals a heart rate with normal conduction but with a rate consistently above 105 beats/minute.

Sedbober [7]

Sinus tachycardia can be the most probable condition which results into high heart rate above 105 beats/minute. This problem is not very serious and is treatable.

<h3>What is Sinus tachycardia?</h3>

Sinus tachycardia is a type of irregular heartbeat which is characterized by a faster than the normal heart rhythm. The heart's sinus node generates electrical impulses which travels through the heart muscle that causes the heart to beat. A normal sinus rhythm has an average heart rate of the range between 60 and 100 beats/minute.

Treatment is not necessary for sinus tachycardia as it is not a very serious issue. However, if an underlying condition is causing these symptoms, it needs to be treated on time. Treatments for sinus tachycardia include medications such as beta-blockers or calcium channel blockers which can lower the heart rate.
