Explanation:
The treatment of ulceration in the foot of diabetic patients should initially be directed against their cause, specifically against pressure. The relief of plantar pressure can be achieved with bed rest and avoiding as much as possible supporting the foot.
In addition to pressure relief, the ulcer should be debrided regularly, with the removal of all callus and non-viable tissue formed around the ulcer. This facilitates the formation of a wound with healthy granulation tissue that heals from the base and not merely from the edges
In case of evidence of vascular insufficiency, the patient should be sent to a vascular surgeon for evaluation. This is particularly important in the absence of signs of healing after 6 weeks. X-rays should be performed to evaluate the foot early in the course of the ulcer and repeated if clinically indicated, due to lack of cure or presence of a deep infection, to detect an osteomyelitis disorder.
The usual attitude is to establish antibiotic treatment with the slightest clinical suspicion of infection. It is likely that the ulcer is colonized by multiple microorganisms, some of which are probably the real cause of an invasive infection, so the wound smears they usually provide little benefit Broad-spectrum antibiotics with aerobic and anaerobic coverage are required, including streptococci and staphylococci, such as amoxicillin-acidoclavulanic, clindamycin or ciprofloxacin (although the latter has poor antistaphylococcal coverage and limited antistareptococcal, penetrates tissues perfectly)
Answer:
When the veins in leaves are irregularly distributed to form a channel, it is known as reticulate Venation. Plants with reticulate venation in their leaves are likely to have tap roots. Plants like carrot or rose have leaves with reticulate venation and tap roots.

Scientists used case studies to help them determine that the right side of the body was connected to the left of the brain and vice versa. A case study is a process or record of research into the development of a particular person, group or situation of a given period of time.
Answer:
d. Hemoglobin helps maintain a constant pH in the blood by binding with H⁺ions released from bicarbonate ions.
Explanation:
The presence (CO₂) in in the erythrocytes lowers its pH as a result the affinity of hemoglobin decreases for oxygen. The carbon dioxide (CO₂) reacts with water to form carbonic acid in the presence of the enzyme carbonic anhydrase which is present in the erythrocytes or red blood cells. The carbonic acid then changes into two ions hydrogen ion (H⁺) and bicarbonate ion (HCO₃⁻). As a result of H⁺ ions, the pH of blood drops. Haemoglobin pick up hydrogen ions to balance the decrease in pH. Thus, haemoglobin helps in maintaining constant pH or keep pH of blood in buffer.
