P wave is the atria “firing”/depolarizing, the QRS complex is the ventricles depolarizing (and the atria are depolarizing while this happens), and the T wave is the ventricles depolarizing. Depolarizing is when it contracts, and repolarizing is when it relaxes and refills.
Answer:
The nurse knows the written instructions for healthcare when a person is incapacitated is called an advance directive. This includes instructions about CPR, death, resuscitation, or prolonging life beyond consciousness.
The caregiver must be authorized to make healthcare decisions for a person who is deemed incapable of giving consent. The advance directive may be in any form written, electronic or oral.
The nurse will help families to create an advance directive that can guide their healthcare needs without having to address those issues.
Explanation:
An advance directive is a document that a person places in physical or electronic form in order to express his or her preferences regarding medical care at the time of incapacitation.
Advance Directives are legal documents written by the incapacitated, living, or deceased. These directives allow families and doctors to abide by their wishes when making healthcare decisions for them.
The nurse takes care of the patient’s life by providing them with the best care possible and should make sure that there is an advance directive on file.

Answer: 1. Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve.
2. Plasma is the main component of blood and consists mostly of water, with proteins, ions, nutrients, and wastes mixed in. Red blood cells are responsible for carrying oxygen and carbon dioxide. Platelets are responsible for blood clotting. White blood cells are part of the immune system and function in immune response.
3.Within the bone marrow, all blood cells originate from a single type of unspecialized cell called a stem cell. When a stem cell divides, it first becomes an immature red blood cell, white blood cell, or platelet-producing cell.
4. Epinephrine and norepinephrine, hormones secreted by the adrenal medulla, raise blood pressure by increasing heart rate and the contractility of the heart muscles and by causing vasoconstriction of arteries and veins. These hormones are secreted as part of the fight‐or‐flight response.
Answer:
What is: Glomeruli; Pyelonephritis
Explanation:
Several diseases that affect other parts of the body can have devastating effects on kidney function. Most of these conditions tend to damage the GLOMERULI, which causes the kidneys to lose the ability to filter, and eventually, to fail. Various types of infections can affect the kidneys themselves, a condition called Pyelonephritis.
