Chronic hypertension causes which of the following changes in blood vessels?
Damage to the tunica intima resulting in swelling and intravascular clotting.
Damage to the tunica media resulting in relaxation of 2 the blood
Damage to the tunica adventitia resulting in bulging of blood vessels.
Damage to the arterioles resulting in Increased flow through blood vessels.
The Correct Answer is A
Chronic hypertension can cause damage to the tunica intima (the inner lining of blood vessels), leading to endothelial injury. This damage can result in inflammation, swelling, and increased risk of clot formation within the blood vessels.

Correct Answer is C
Explanation
This is how Inhalation Works:
Inhalation is the process of drawing air into the lungs. Here's a step-by-step explanation:
Diaphragm and Intercostal Muscle Contraction:
The diaphragm (a dome-shaped muscle located at the base of the lungs) contracts and moves downward.
The intercostal muscles (muscles between the ribs) contract, pulling the ribcage upward and outward.
Expansion of the Thoracic Cavity:
The contraction of these muscles increases the volume of the thoracic cavity (the chest area).
As the thoracic cavity expands, the pleural cavity (the space between the lung and chest wall) also expands.
Creation of Negative Pressure:
The expansion of the thoracic cavity reduces the pressure within the lungs.
This pressure is now lower than the atmospheric pressure (pressure of the air outside the body).
Air Flow into the Lungs:
Due to the negative pressure, air flows from the higher atmospheric pressure outside the body into the lower pressure inside the lungs.
Air travels through the trachea (windpipe), into the bronchi (two main air passages into the lungs), and finally into the alveoli (tiny air sacs where gas exchange occurs).
Correct Answer is ["A","C","D"]
Explanation
Choice A reason:
If Mr. Greene has memory retention and a neurological evaluation that has demonstrated understanding of how to follow the sliding scale and recognize proper dosage, use, and potential side effects of insulin, he is a candidate for self-administration. This ensures he can manage his insulin therapy safely and effectively.
Choice B reason:
If Mr. Greene states “I can do it” but has severe hand tremors, he is not a candidate for self-administration of insulin. Severe hand tremors can impair his ability to accurately draw up and administer the correct dose of insulin, increasing the risk of errors.
Choice C reason:
If Mr. Greene demonstrates the ability to self-administer insulin over a period of time successfully using the “Teach Back” method by a number of staff or visiting nurse, he is a candidate for self-administration. The “Teach Back” method confirms that he understands and can perform the procedure correctly.
Choice D reason:
If Mr. Greene no longer is actively suicidal and has hand-eye coordination that is accurate, he is a candidate for self-administration of insulin. Accurate hand-eye coordination is essential for safely drawing up and administering insulin.
