Correct Answer is ["A","B","C","G"]

Explanation

A. Administering epinephrine intramuscularly is the first-line treatment for anaphylaxis, as it counteracts the effects of histamine and reduces swelling.
B. Starting intravenous access allows for fluid resuscitation and the administration of medications like epinephrine or corticosteroids.
C. Providing supplemental oxygen is necessary to support the patient's breathing and improve oxygenation during an anaphylactic reaction.
D. Corticosteroids may be used later to reduce inflammation, but they are not first-line treatments for anaphylaxis.
E. Placing the patient in a supine position with legs elevated may be helpful for circulation, but it is not the priority over administering epinephrine.

F. Oral antihistamines are not effective in the acute management of anaphylaxis, which requires immediate action.
G. Ensuring the patient's airway is patent is the top priority, as airway compromise can occur rapidly during anaphylaxis.
H. Encouraging oral fluid intake is not appropriate in this emergency situation, as intravenous fluids are needed.
I. Monitoring the patient's skin for rashes is important but secondary to managing the airway and circulation.

A. Advise the patient to take antacids only when severe pain occurs. B. Instruct the patient to eat three large meals per day. C. Encourage the patient to smoke to reduce stress. D. Recommend increased intake of spicy foods to boost metabolism. E. Suggest the patient use NSAIDS for pain relief. F. Advise the patient to drink coffee to help with digestion. G. Administer proton pump inhibitors as prescribed. H. Encourage the patient to consume a bland diet.

Correct Answer is ["G","H"]

Explanation

A. Advising the patient to take antacids only when severe pain occurs may not be effective. Antacids should be used regularly or as prescribed for consistent symptom relief.
B. Instructing the patient to eat three large meals per day may exacerbate symptoms; smaller, more frequent meals are often better for managing gastritis.
C. Encouraging smoking to reduce stress is harmful, as smoking can exacerbate gastritis and increase stomach acid production.
D. Spicy foods should be avoided in gastritis, as they can irritate the stomach lining.
E. NSAIDs should be avoided in gastritis because they can irritate the gastric mucosa and worsen symptoms.
F. Coffee can stimulate acid production and may irritate the stomach lining, so it should be avoided.
G. Proton pump inhibitors (PPIs) help reduce gastric acid secretion and are a mainstay treatment for gastritis.
H. A bland diet is recommended, as it avoids irritating foods and allows the stomach lining to heal.
