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:
See below
Explanation:
Check to see if the test requires a fasting period ( NPO ) before proceeding.
Veins are favored over arteries because they have thinner walls, and thus they are easier to pierce. There is also lower blood pressure in veins so that bleeding can be stopped more quickly and easily than with arterial puncture.
The client who must be placed in airborne precautions is the client with a positive PPD (purified protein derivative) who has a positive x-ray for a suspicious tuberculin lesion.
Airborne precautions are steps that healthcare ability callers and stick need to attend when going into or leaving a patient's range. Airborne carefulness is for cases where one has a beginning that can spread through the air. They help stop beginning from extending so additional society forbiddance vomit.
PPD is a test used to discover if you have infection contamination. It will not cause infection contamination. This cure can be secondhand for different purposes; request your health management wage earner or druggist if you have questions. The purified protein derivative is an irritant (an essence that excites the invulnerable structure to remove or fight external entities in the party), that is introduced under the skin in the radius. After 48 to 72 hours the dose section is judged by a surgeon.
