If a patient is unable to make decisions due to age or incapacity, a substitute decision-maker can act on their behalf. This often involves a health care proxy appointed through an advance directive, which includes decisions on medical treatment preferences.
Explanation:If a patient is unable to make decisions by reason of age or incapacity, a substitute decision-maker may substitute his or her judgment on behalf of the patient. This concept is part of paternalism, where the desires of someone are overridden because they are not considered competent to make the right decision. In healthcare, a health care proxy is a legal document that appoints a specific individual to make medical decisions for a patient if they are unable to speak for themselves. This may be part of an advance directive, which also includes a living will that specifies desired medical treatments in various scenarios where the patient is incapable of making decisions.
Parents often provide consent on behalf of their children, as children are not competent to give informed consent due to their age. Special accommodations in developmental research are made for this reason, with researchers obtaining written informed consent from a parent or legal guardian. Furthermore, individuals are encouraged to participate in advance care planning to outline their preferences for future healthcare decisions.

About 43% of blood consists of red blood cells.
True
False
The claim that about 43% of blood is made of red blood cells is false. The correct percentage is approximately 45%, based on the hematocrit measure. Plasma constitutes about 55% of blood volume.
Explanation:The statement that about 43% of blood consists of red blood cells is false. In humans, the erythrocytes or red blood cells make up approximately 45% of the total blood volume, a value that is assessed with a measure known as the hematocrit. This proportion can vary slightly based on individual health and biological factors. Blood itself is composed of two main components: the cellular elements and the plasma. The plasma, which is the fluid component of blood, makes up about 55% of the blood volume. It carries water, proteins, electrolytes, lipids, glucose, and the formed elements including red cells, white cells, and platelets. Red blood cells are specialized for carrying oxygen due to the hemoglobin they contain, which is an iron-rich protein that facilitates oxygen transport.
The statement that about 43% of blood consists of red blood cells is essentially true since the hematocrit value is usually around 45%, which is close to 43%.
Explanation:The statement that about 43% of blood consists of red blood cells is essentially accurate, as the typical range of the hematocrit, the proportion of blood volume that consists of red blood cells, is around 45%. Therefore, the approximate percentage of blood consisting of red blood cells may vary slightly from the stated 43%, but it is very close to the actual average value. The hematocrit is used clinically to measure the proportion of red blood cells in the blood, reflecting the blood's capacity to carry oxygen.
The cellular components, which include red blood cells, white blood cells, and platelets, normally make up approximately 45 percent of the blood. The remaining 55 percent is plasma, which contains water, proteins, electrolytes, lipids, glucose, and other components. Since the hematocrit value is close to the 43% provided in the statement, it would suggest that the percentage of red blood cells in a person's blood is quite close to 43%, and thus the original statement can be considered true.

STARVATION VS MALNUTRITION SPOT THE DIFFERENCES 40 POINTS! pls ily
Starvation is the extreme lack of food leading to body tissue depletion, while malnutrition includes both under and overnutrition, referring to an imbalance, excess, or lack of nutrient intake.
Starvation vs. Malnutrition:
Though the terms starvation and malnutrition might be used interchangeably at times, they have distinct definitions and consequences. Starvation occurs when the body has exhausted its fat reserves, and muscle mass begins to be broken down to meet energy needs. This leads to severe weight loss and body tissue depletion. In contrast, malnutrition refers to inadequate, excessive, or imbalanced consumption of nutrients. Undernutrition, a form of malnutrition, can lead to conditions like kwashiorkor, known for symptoms like distended bellies in children due to a lack of calories and protein.
Both starvation and malnutrition can occur in any demographic, regardless of geographical location or socio-economic status. Overnutrition, another form of malnutrition, can lead to obesity and other associated health risks like heart disease, cancer, diabetes, and stroke. Knowledge about nutrition and access to a healthy diet are crucial in preventing both starvation and malnutrition. It's important to recognize that not only the underprivileged but also individuals in developed areas can suffer from these conditions if their diet lacks essential nutrients.

The knee cap is the ____
The knee cap, known as the patella, is the largest sesamoid bone in the body and is found in the tendon of the quadriceps femoris muscle. It protects the muscle tendon from rubbing against the distal femur and does not articulate with the tibia.
Explanation:The knee cap is also known as the patella. It is the largest sesamoid bone in the body. Sesamoid bones are those embedded in a tendon crossing a joint, in this case, the knee joint.
The patella is found in the tendon of the quadriceps femoris muscle which is the large muscle of the front thigh. Its primary role is to protect the muscle tendon from rubbing against the distal femur during movements of the joint.
Besides, the patella lifts the tendon away from the knee joint which increases the leverage power of the quadriceps femoris muscle as it acts across the knee. Importantly, the patella does not articulate directly with the tibia; it interacts with the patellar surface of the femur.

Pasteurization is used to heat milk and remove any disease-causing organisms. It does not change the nutritional value or taste of the food. Some foods can also be pasteurized; however, if meat is heated, the value and taste change.

A. irradiation
B. antibiotics
C. sterilization
D. filtration
The right answer is A. irradiation.
Food irradiation involves exposing foods to ionizing radiation to reduce the number of microorganisms they contain. Although it is a controversial method of food preservation, it is widely used. This process has been authorized by the Food and Drug Administration and the United States Department of Agriculture. WHO has accepted it for human consumption after extensive scientific research.
It differs from sterilization because it does not necessarily aim to destroy all the germs; Irradiation effectively destroys certain micro-organisms and many bacteria of the Vibrio genus (V. vulfunicus, V. cholerae, V. parahaemolyticus), for example, but strains very resistant to radioactivity or radioresistant are known. Finally, this method can not totally eliminate the risk of viral diseases such as norovirus or hepatitis A virus, but can nevertheless reduce the risk of infection, according to the 2013 publication of the results of work conducted by the University of Delaware.
