Answer:
The best answer from the choices, to the question: The cause of the hyperventilation is described by which of the following statement:___, would be, B: A decrease in the bicarbonate concentration stimulates ventilation.
Explanation:
The acid-base balance in the human body, is a very restrictive one. Normal ranges in this base are: 7.35 to 7.45. Whenever the values go either below 7.35 or above 7.45, we are talking about a person going into acidosis or alkalosis. Both situations are pretty serious and they have to do with the balance between the amounts of bicarbonate, and CO2 in the form of carbonic acid, in the blood. The normal ratio of bicarbonate to carbonic acid, is usually 20:1. Chemoreceptors, especially central ones in the neck, measure constantly that the balance is kept and if this is not the case, then several mechanisms will be put into place to recover it. One such measure is respiratory, and the other is metabolic. In the case of this 17-year-old, he has a pneumonia, which means that from the start, one of his recovery mechanisms is impeded, which is the respiratory mechanism of balance. He is also having metabolic problems with his system of compensation because his body is already producing high levels of H+ ions and not enough bicarbonate. Hyperventilation in this person is attempting to expel as much CO2 as possible, to try and restore the balance. The first thing that is sensed by the receptors is the changing in the 20:1 ratio, the increase in pH due to too much carbonic acid, and thus the body initiates the use of CO2 expulsion by the lungs, while metabolic mechanisms come into play.
Both cancers involve the same genomic change in homologous chromosomes. The only difference is that the first mutation is inherited and the second is somatic in familial cancer, whereas in sporadic cancer both mutations are somatic.

The nurse must first see what is at greatest risk of life.
<h3>Which client should the nurse assess first?</h3>
The nurse should first assess the client showing symptoms of a deep venous thrombosis (DVT) (eg, unilateral edema , warmth, redness , tenderness on palpation).
<h3>Which patients should be seen first?</h3>
In triage, a nurse typically prioritizes each patient's condition into one of three general categories:
- Immediately life threatening
- Urgent, but not necessarily immediately life threatening
- Less urgent.
With this information, we can conclude that The first phase of the nursing process is the assessment phase. In this phase, the nurse collects and organizes data related to the patient. Data includes information about the patient, family, caregivers, or the patient's community or environment as it is relevant to his health and well-being.
