Which of the following would affect heart rate in a similar way to activation of the parasympathetic ANS? Group of answer choices a. Norepinephrine antagonists
b. Overexpression of norepinephrine receptors on cardiac muscle
c. Reduce AChR expression on the cardiac muscle
d. Increased nicotinic receptor expression on skeletal muscle Atropine

Answers

Answer 1
Answer:

Norepinephrine antagonists would affect heart rate in a similar way to activation of the parasympathetic ANS.

Answer: Option A

Explanation:

Norepinephrine is responsible for increasing the rate of the heart and causes contraction of the muscles. Having an antagonist norepinephrine would act in the opposite way and would decrease the rate of the heart and help relax the body of the human.

It will act in a similar way to activation of parasympathetic ANS which is responsible for the decreasing the heart rate and increasing the digestion at a faster rate. It relaxes the body of the humans.

A patients pulse oximetry reading is 92%. What is the bestmethod of oxygen administration for this patient?

Answers

Answer:

A low flow oxygen supply

Explanation:

92% is the threshold for hypoxia, meaning that below 92% a person may need Oxygen supply. Depending of each patient's level of saturation, there are different types of devices and pressures, the lower the Oxygen concentration the more the pressure needed, for 92% a patient may require a low pressure system, such as nasal cannula for supply from 24 to 40% of Oxygen concentration. The second option is a face mask, which provides  between 28% and 50%.
