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.

Urinary strictures
Bethanechol chloride (Urecholine) can be harmful to patients who have a urinary tract obstruction or bladder wall weakness. The medication has the ability to contract the bladder, causing pressure to build up in the urinary tract. In these patients, an increase in urinary tract pressure could cause the bladder to rupture.
What is Urinary retention?
- The inability to completely empty the bladder is referred to as urinary retention. The onset can be abrupt or gradual.
- Symptoms of sudden onset include inability to urinate and lower abdominal pain.
- When symptoms appear gradually, they may include loss of bladder control, mild lower abdominal pain, and a weak urine stream.
- If there is an obstruction or stricture (narrowing) in or around the bladder, or if the muscles in or around the bladder are weak, urine may be retained. Urinary retention can also be caused by certain types and locations of tumors, certain medications, being dehydrated, or having constipation.
