Answer:
D. WBC count
Explanation:
First, let's define symptom and sign.
A <u>symptom</u> is some sort of evidence that could suggest a disease or disorder, but it must be observed and noticed by the patient. Basically, it's what the patient feels.
So, a headache, pain, and nausea are all symptoms.
A <u>sign </u>is evidence that someone else observes or collects. So, a family member or doctor sees signs.
Therefore, temperature, white blood cell count, and pulse are all signs.
The question asks us which is a sign, not a symptom. Therefore, the best choice is D. WBC count
Answer:
C) substitutions that reduce the affinity of hemoglobin for oxygen
Explanation:
Heinz bodies are inclusions in the eritrocite, filled by denaturalized globin (protein part of the hemoglobin). Hemoglobin is formed by 4 globin subunits (2 alpha chains and 2 beta chains) plus a heme group. The latter, is responsible for oxygen binding.
The denaturalization of the globin is caused by substitutions that do not allow the protein to fold properly and bind the heme group accordingly. This is the cause of the Heinz bodies in the eritrocite. Therefore, this is a structural problem that impedes the protein to fold into a functional protein and has nothing to do with hemoglobin having less affinity for oxygen. In the last mentioned case, the protein is still functional but poorly binds oxygen, hence, does not for Heinz bodies.
Answer:
CPR.
Explanation:
Because when the client/patient is been rushed to the ED with pulmonary edema they won't breathe if anyone doesn't save them when they need oxygen at the most urgently needingless times.
