Mumz [18]

Answer:

Fluorine

Explanation:

Data obtained from the question include:

The isotope of fluorine has:

Proton = 9

Neutron = 10

The atomic number is the proton number of the atom.

Therefore, the atomic number = 9

Mass number = proton + Neutron

Mass number = 9 + 10

Mass number = 19

Now comparing the above with the fluorine atom in the periodic table. We'll discover that the isotope is actually fluorine atom.

Therefore, the name of the isotope is fluorine

A client comes to the emergency department with status asthmaticus. His respiratory rate is 48 breaths/minute, and he is wheezin
Tema [17]

Answer:

The disorder is called Respiratory alkalosis

Explanation:

A client with asthma can hyperventilate (excess of O2). This oxygen excess can lead also to a lack of carbon dioxide (CO2) (acid substance) which can causes alkalosis (increasing the pH values in blood and body).

In this medical condition (respiratory alkalosis), the bicarbonate (HCO3-) hosted in the kidneys has a late response, so the  HCO3- level  in the client remains normal.

The PaCO2 (partial pressure of arterial carbon dioxide) is low in comparison with normal values so that indicates loss of CO2 in the respiratory system.
