Which type of medication is the first-line treatment for nasal congestion?
Nasal Glucocorticoids
Leukotriene Modifiers
Decongestants
Antihistamines
The Correct Answer is A
Nasal glucocorticoids, also known as intranasal corticosteroids, are considered the most effective and recommended first-line treatment for nasal congestion caused by allergic rhinitis or non-allergic rhinitis. They work by reducing inflammation in the nasal passages, relieving congestion, and improving other symptoms such as itching, sneezing, and runny nose.
Leukotriene modifiers, decongestants, and antihistamines can also be used to manage nasal congestion, but they are generally considered second-line options or adjunct therapies.
Decongestants provide temporary relief by constricting blood vessels in the nasal passages, while antihistamines help with symptoms related to allergies. Leukotriene modifiers are primarily used for managing asthma and are not typically the first choice for nasal congestion alone.

Correct Answer is D
Explanation
Leukotriene receptor antagonists (LTRAs) like Montelukast are commonly used in the treatment of asthma. They work by blocking the action of leukotrienes, which are inflammatory substances that can cause narrowing and inflammation of the airways in individuals with asthma. By preventing this inflammation, LTRAs help to reduce asthma symptoms and prevent asthma attacks.
The other options mentioned in the statements are not accurate or appropriate for teaching about Montelukast. Taking the medication only when experiencing symptoms is not the recommended approach, as LTRAs are typically taken regularly as part of ongoing asthma management. The statement about the therapeutic effect taking several weeks to notice is not accurate, as Montelukast can start to provide symptom relief within a shorter timeframe.
Additionally, the statement about increasing fiber and fluid intake to prevent constipation is unrelated to the use of Montelukast and may not apply to this medication specifically.
Correct Answer is C
Explanation
The sympathetic nervous system postganglionic neurons primarily release norepinephrine as their neurotransmitter. These neurons are part of the autonomic nervous system and are responsible for coordinating the body's "fight or flight" response to stress or danger.
Norepinephrine acts as a neurotransmitter at the postganglionic synapses and binds to adrenergic receptors in the target tissues, mediating the physiological responses associated with sympathetic activation.
While acetylcholine is the primary neurotransmitter released by the preganglionic neurons of the sympathetic nervous system, it is not the neurotransmitter released by postganglionic neurons. Epinephrine (also known as adrenaline) is released into the bloodstream by the adrenal medulla and acts as a hormone, not a neurotransmitter. Arginine is an amino acid and is not directly involved in the neurotransmission of the sympathetic nervous system.
