Answer:
\rb. To accelerate the heart rate by interfering with vagal impulses
Explanation:
Digoxin is a cardiac glycoside which has both the cardiac as well as the electric effects. The most important electrical effect includes early parasympathomimmetic responses(decrease in heart rate) which are followed by late arrhythmogenic actions. Thus the parasympathetic effects of digoxin specifically on atria and AV node results in a decrease in heart rate while atropine in given in this condition because it is a parasympatholytic drug thus it reverses the bradycardia induced by digoxin by interfering with vagal impulses and increases the heart rate .
Hence the option \rb. To accelerate the heart rate by interfering with vagal impulses is true.
Answer: d. autonomic nervous system
Explanation:
The dilation of the pupil occurs due to the radial muscles. This is controlled by the autonomic nervous system. The autonomic nervous system consists of sympathetic and parasympathetic nervous system. The sympathetic nervous system controls the dilation of pupil whereas the parasympathetic nervous system controls the contraction of pupil.
A dilation response generally involves the widening of the pupil that may be caused by the adrenaline and drugs like cocaine, MDMA, amphetamines, hallucinogens and dissociatives.
Answer:
The thyroid gland absorbs almost all of the iodine in the body. When radioactive iodine (RAI), also known as I-131, is given to the body as a liquid or capsule, it becomes concentrated in thyroid cells. Radiation can kill the thyroid gland and any other thyroid cells or tissues (including cancer cells) that absorb iodine, without damaging any other organs.
Explanation:
The thyroid gland is an organ that belongs to the endocrine system and its function is to synthesize hormones that are responsible for controlling the body's metabolism, this gland has an important characteristic and that is that the hormones it produces have a unique chemical composition due to They are the only hormones that contain iodine in their structure, this in turn is essential for its functioning because the body does not synthesize it and it must be consumed in the diet. When a small dose of the radiopharmaceutical iodine 131 (Sodium Iodide 131I) is consumed, it is absorbed into the bloodstream and concentrated by the thyroid gland, where it begins to destroy cancer cells in the gland. 131I quickly attaches itself to thyroid cells to destroy them, but continues to emit radioactivity for a long time: it takes 8 days to halve. The beta radiation particles of 131I, which we call radioiodine or radioactive iodine, have a range of 2mm and act for a long time in a constant way. Fortunately, the body's metabolism quickly expels iodine through the urine, so that in one day the amount of iodine has decreased considerably.
Allergic conjunctivitis.
The fact that symptoms are in both eyes with watery discharge, no vision changes, and intense itching sounds mostly like allergic conjunctivitis, especially considering the swollen condition of the tarsal conjunctiva.
<h3>What is Allergic conjunctivitis?</h3>
- An allergic reaction can result in allergic conjunctivitis, an inflammation of the conjunctiva.
- Conjunctival inflammation may result from allergic reactions brought on, for instance, by allergens in the air.
- Common symptoms include redness, itching, swelling, tearing, and stringy discharge.
- Different eye drops could reduce discomfort and inflammation.
<h3>Why does allergic conjunctivitis occur?</h3>
- When the conjunctiva swells or becomes inflamed as a result of an allergic reaction to pollen, dust mites, pet dander, mold, or other allergens, this condition is known as allergic conjunctivitis.
<h3>How is allergic conjunctivitis treated?</h3>
- ice compress.
- synthetic tears eye drops or oral medicines for allergies (over-the-counter or prescription).
- Immunotherapy for allergies.
<h3>How long does last before it goes away?</h3>
- Although they often go away within 24 hours of the allergen being removed, symptoms can be severe.
- Seasonal allergic conjunctivitis (SAC) is a type of ocular allergy that typically manifests as lesser but more enduring symptoms during a certain pollen season (s).
