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.
Answer:
The correct answer is e. dermis
Explanation:
Lymph capillaries are thin walled capillaries interwoven with blood capillaries and found throughout the body except nervous system, bone marrow, and tissues that do not contain vascular tissue like epidermis.
The role of lymphatic capillaries is to collect the extra fluid which is secreted by the tissues in the intercellular spaces. This fluid is called lymph and is clear and transparent and contains WBCs and plasma.
Lymph is different from blood because it do not contain RBCs and platelets. Lymphatic vessels are important part of body immunity because it contains many WBCs in their lymph helpful in fighting diseases.
Answer:
3 Monitor intake and output
Explanation:
This client is admitted for heart failure and acute pulmonary edema, which means that his/her heart is not pumping blood as it should, and that there's liquid in the lungs, causing the client symptoms such as dyspnea (shortness of breath).
IV Furosemide, a loop diuretic is prescribed. This drug increases renal excretion of water and electrolytes out of the body, resulting in the mobilization of excess fluid from the body and a decrease in blood pressure. The indication to give the client a second dose of furosemide in an hour is because of its delayed effect.
Since furosemide causes liquids to exit the body, it is important to monitor fluid balance in order to evaluate the effectiveness of this medication. Monitoring fluid balance refers to observing and registering all liquids that come in (IV, orally) and out (urine) of the body. For the client, being admitted to the hospital and receiving IV medication, the nursing personnel should be registering all the liquids the client is receiving (IV and orally) and voiding (urine).
