How are the hypothalamus and pituitary able to control the majority of the endocrine system?

1- Which of the following would be appropriate actions following transcutaneous pacing?

Consult a specialist.

Follow VT/VF algorithm

Administer amiodarone.

Confirm ET tube placement with quantitative waveform capnography.

2- What reason is NOT valid during the critical early defibrillation for individuals experiencing sudden cardiac arrest?

Individuals in asystole respond well to early defibrillation.

A common initial rhythm in out-of-hospital witnessed sudden cardiac arrest is ventricular fibrillation (VF).

The most effective treatment for ventricular fibrillation (VF) is electrical defibrillation.

The probability of successful defibrillation decreases quickly over time.

3-The best treatment for ST-elevation MI (STEMI) is:

Epinephrine and vasopressin

Early reperfusion therapy

Lidocaine and magnesium

Rapid transfusion

How do arteries maintain blood pressure even when the heart isn't pumping out blood during diastole?

In patients with poliomyelitis, motor neurons are destroyed, causing loss of muscle function and even flaccid paralysis. Sometimes recovery occurs because of the formation of axon branches from the remaining motor neurons. These branches innervate the paralyzed muscle fibers to produce motor units with many more muscle fibers than usual, resulting in the recovery of muscle function. What effect would this reinnervation of muscle fibers have on the degree of muscle control in a person who has recovered from poliomyelitis?

Tyler is 22 years old and wants to be a bodybuilder. He works hard during the week at his job so he goes out to party every Friday and Saturday night in which he drinks a lot of alcohol. Recently, Tyler has checked his weight and saw that his fat mass has increased. He doesn’t understand why this is the case when he tracks his carbs, protein, and fat every day. He tracks his calories every day except when he is partying because he drinks low calorie beers. He has now come to you seeking advice on what could be going on and what are some alternatives he can do to start losing fat mass while still partying and drinking alcohol.
