Answer:
Aldosterone is the hormone produced by the adrenal cortex, aldosterone is a hormone that inhibits the level of sodium excreted in the urine, maintaining volume and blood pressure.
Explanation:
Several hormonal systems regulate the urinary and intestinal excretion of potassium, so that its activation can produce hypokalemia, and its hyperkalemia blockade.
The most important hormonal axis is the renin angiotensin aldosterone (SRAA) system and the β-adrenergic hormones. In addition to increasing the renal excretion of potassium and the secretion of this cation by the salivary, sweat glands and the intestine, aldosterone can also favor the entry of potassium into the cell.
Aldosterone increases distal sodium reabsorption and potassium secretion. Aldosterone secretion by the adrenal glands is stimulated in hyperkalemia and is inhibited in hypokalemia.
Aldosterone modulates renal excretion of potassium:
- Increasing the intracellular concentration of potassium by stimulating the activity of the Na-K-ATP-Basolateral pump
- Increasing the density and activity of the ENaC channel
- Increasing the expression of ROMK channels
It is true that the primary function of the humoral, or antibody-mediated, immune response is to control freely circulating pathogens.
What is humoral immunity?
Humoral immunity is the immunity to infection due to antibodies, which circulate in the blood and lymph, and which are produced by B cells.
Generally, immunity is the resistance of an organism to disease-causing agents or foreign substances.
However, the humoral immune system deals with antigens from pathogens that are freely circulating, or outside the infected cells.

Answer:
A. Glaucoma
Explanation:
Elevated intraocular pressure is a concern in people with ocular hypertension because it is one of the main risk factors for glaucoma. High pressure inside the eye is caused by an imbalance in the production and drainage of fluid in the eye (aqueous humor).
Patients with suspected strokes must be assessed within 10 minutes of arrival in the emergency department by the stroke team and other experts. Within 10-25 minutes, the CT scan must be completed, and within 45 minutes it must be read.
Hospital need to Obtain a 12-lead ECG and perform neurologic screening assessment. Do not delay CT, obtain CT without contrast within 20 minutes of patient arrival. A neurologic assessment by the stroke team or designee should be done within 20 minutes of patient arrival to the ED.
A CT scan of the head is usually one of the first tests used for a stroke. A CT scan can show bleeding in the brain or damage to brain cells. The CT scan also can find other problems that can cause stroke symptoms.
