Which answer is NOT true about allergic rhinitis
Correct Answer
A. Caused by GI infections
2.
Histamine causes allergy symptoms
Correct Answer
A. True
Explanation
Histamine is a chemical released by the immune system in response to an allergen. It is responsible for triggering allergy symptoms such as itching, sneezing, runny nose, and watery eyes. When histamine is released, it binds to specific receptors in the body, leading to inflammation and the characteristic allergic reactions. Therefore, it is correct to say that histamine causes allergy symptoms.

What do you know about histamine
Correct Answer(s)
B. is a chemical mediator of inflamitory response
C. Histamine1 is found in smooth muscle of the vascular system and bronchial tree
E. H2 is found in stomach and is responsible for peptic ulcers
Explanation
Histamine is a chemical mediator of the inflammatory response, meaning it plays a role in the body's immune response to injury or infection. Histamine1 is found in the smooth muscle of the vascular system and bronchial tree, where it helps regulate blood vessel dilation and bronchoconstriction. On the other hand, histamine2 is found in the stomach and is responsible for the production of stomach acid, which can lead to the development of peptic ulcers.

Which drugs are opiod antitussives?
Correct Answer(s)
A. Codiene
C. Hydroconone
D. Homatropine(hycodan)
Explanation
The drugs codeine, hydrocodone, and homatropine (Hycodan) are all opioid antitussives. Opioid antitussives are medications that suppress or relieve coughing by acting on the cough reflex in the brain. Codeine and hydrocodone are commonly used to treat coughs, while homatropine (Hycodan) is often used in combination with hydrocodone to provide additional antitussive effects. These drugs work by reducing the sensitivity of the cough reflex, helping to alleviate cough symptoms.

The prototype drug: fluticasone (Flonase) is an Intranasal Glucocorticoids. what else is correct
Correct Answer(s)
A. Decreases local inflammation in nasal passages, thus reducing nasal stuffiness
C. Nasal irritation epistaxis are side effects
Explanation
Fluticasone (Flonase) is classified as an Intranasal Glucocorticoid, which means it works by decreasing local inflammation in the nasal passages. This action helps to reduce nasal stuffiness. However, it is important to note that nasal irritation and epistaxis (nosebleeds) are potential side effects of using this drug. Therefore, the correct answer states that fluticasone decreases local inflammation in the nasal passages, reducing nasal stuffiness, while also mentioning the side effects of nasal irritation and epistaxis.

Pt teaching for antihystamine therapy includes
Correct Answer
B. Use with extreme caution in clients with asthma or COPD, cardiovascular disease and hyperthyroidism
Explanation
The correct answer suggests that antihistamine therapy should be used with extreme caution in clients who have asthma or COPD, cardiovascular disease, and hyperthyroidism. This is because antihistamines can potentially worsen the symptoms of these conditions or interact with medications used to treat them. Therefore, healthcare providers need to carefully consider the risks and benefits of using antihistamines in these individuals and closely monitor their response to the therapy. The answer does not provide any information about teaching for older adults, children, or giving babies half a spray in the eyes, so it is not relevant to the explanation.

The answer also emphasizes the importance of assessing for adverse effects such as dizziness, drowsiness, blurred vision, headache, and epistaxis. Additionally, it advises caution when using these medications in patients with a history of gastrointestinal disorders.
