Explanation
Blood specimens should be labelled after collection, in the patient's room. This is because labelling the specimens immediately after collection ensures accurate identification and prevents any mix-ups or confusion later on. Labelling in the patient's room also reduces the risk of misidentification during transportation to the lab. Additionally, labelling in the patient's room allows for immediate verification of patient information and ensures that the correct specimen is being labelled for the right patient.

Explanation
A mono-test can be done using either serum or plasma specimens. Serum and plasma are both components of blood and can be used interchangeably for this particular test. The test is designed to detect the presence of mononucleosis, a viral infection caused by the Epstein-Barr virus.

Insulin decreases blood glucose levels by promoting the uptake of glucose into cells and the storage of excess glucose as glycogen. On the other hand, glucagon increases blood glucose levels by stimulating the breakdown of glycogen into glucose and the release of glucose into the bloodstream.

Explanation
The cephalic vein is the easiest vein to palpate in obese patients because it is located on the outer side of the arm, close to the surface of the skin. This makes it more accessible and easier to feel or touch, even in patients with excess adipose tissue. The other veins mentioned, such as the median, cubital, and basilic veins, may be more difficult to locate or palpate in obese patients due to their deeper positioning or proximity to other structures.

Explanation
The functional unit of the kidney is called the nephron. Nephrons are responsible for filtering waste products and excess water from the blood, producing urine, and maintaining the body's water and electrolyte balance. They consist of a glomerulus, which filters the blood, and a tubule, which reabsorbs necessary substances and excretes waste products. The ureter is a tube that carries urine from the kidneys to the bladder, while the urethra is a tube that carries urine from the bladder out of the body. However, neither of these structures is the functional unit of the kidney.

Explanation
In a blood donation session, one person can donate up to 500ml of blood. This is the standard amount that is commonly accepted and considered safe for the donor. Donating more than this amount could potentially lead to health risks and complications for the donor. Therefore, it is important to adhere to the recommended 500ml limit to ensure the well-being of the donor.
