Answer:
Necrosis is an uncontrolled and passive process that usually affects large fields of cells, whereas apoptosis is a controlled and energy (ATP)-dependent event usually limited to individual or small clusters of cells.
Answer:
Option A
Explanation:
Complete question is
A client with a digoxin level of 2.4 ng/ml has a heart rate of 39. The health care provider prescribes atropine sulfate. Which of the following best describes the intended action of atropine for this client?
Select one:
a. To accelerate the heart rate by interfering with vagal impulses.
b. To reduce peristalsis and urinary bladder tone.
c. To dry oral and tracheobronchial secretions.
d. To stimulate the SA node and sympathetic fibers to increase the rate.
Solution -
Atropine improves the performance and output of cardiac system by inhibiting the action of vagal or parasympathetic. The rate of discharge from the sinus node (SN) increases and hence the chances of ventricular ectopy reduces.
This drug must be administered rapidly to prevent reflexes of bradycardia. The common dosage regime is 0.5 mg per 3 minutes in adults or as per the instructions of doctor.
Hence, option A is correct
Answer:
True
Explanation:
The air, aka the atmosphere, is like a protective blanket around the Earth that keeps it warm amongst other things.
Answer;
The fibrous pericardium is not distensible, which causes the blood to put pressure on the heart, constricting it and reducing its ability to contract
Explanation;
-Cardiac tamponade is a clinical syndrome caused by the accumulation of fluid in the pericardial space, resulting in reduced ventricular filling and subsequent hemodynamic compromise.
-The most common causes of cardiac tamponade are; rupture of an aortic aneurysm (a bulge in the wall of the aorta), advanced lung cancer, acute pericarditis (inflammation of the pericardium), a heart attack, and heart surgery.
