Answer:

Actually, in physical cosmology, Big Bang nucleosynthesis (or primordial nucleosynthesis) refers to the production of nuclei other than H-1, the normal, light hydrogen, during the early phases of the universe, shortly after the Big Bang. About first millisecond, the universe had cooled to a few trillion kelvins (1012 K) and quarks finally had the opportunity to bind together into free protons and neutrons. Free neutrons are unstable with a half-life of about ten minutes (614.8 s) and formed in much smaller numbers. The abundance ratio was about seven protons for every neutron. Before one neutron half-life passed nearly every neutron had paired up with a proton, and nearly every one of these pairs had paired up to form helium. By this time the universe had cooled to a few billion kelvins (109 K) and the rate of nucleosynthesis had slowed down significantly.

________ drugs relax smooth muscle in the walls of the arteries, cause the arteries to dilate, and are used to treat hypertensio
Vikki [24]

Answer:

Peripheral vasodilators

Explanation:

Peripheral dilators are a form of vasodilators that are involved in the dilation of the most distal parts of the vascular system such as the venules and arterioles. It does this by relaxing the smooth muscle of the blood vessels that are wide open, therefore making it easier for the heart to pump blood through  blood vessels and also the whole body.

In the treatment of hypertension, the peripheral dilators lower blood pressure by decreasing the total peripheral resistance of the arteries. In addition to the treatment of hypertension, they are also used in the treatment of heart failure and acute myocardial infarction.

An example is isoxsuprine.

Vinil7 [7]
<span>The nurse should first assess the patient for any injuries to themselves. Once it has been established that the patient is unharmed, therapeutic communication needs to be initiated. It is important to actively listen and empathize with what the patient is trying to say. Engage the patient in positive communication and discuss treatment options. The nurse will need to evaluate the situation as a whole and if it gets out of control and the patient poses a threat to themselves, the nurse can contact their charge nurse to see what other options can be done. Perhaps he/she may also consider contacting the doctor for pharmacological interventions if the patient is unable to calm themselves down?</span>
