An ulcer caused by H. pylori can be successfully treated with which classification of drugs?

A) Stool softener:
Stool softeners, such as docusate sodium, work by adding moisture to the stool, making it softer and easier to pass. They do not directly stimulate bowel movements or peristalsis through irritation of the bowel lining.

B) Saline/osmotic laxative:
Saline or osmotic laxatives, such as magnesium hydroxide (milk of magnesia) and polyethylene glycol (PEG), work by drawing water into the intestines, which softens the stool and increases bowel motility. They do not primarily act by irritating the bowel lining.

C) Stimulant laxative.
Stimulant laxatives work by directly stimulating the nerves in the intestines, which increases the rhythmic contractions of the intestines (peristalsis) and promotes bowel movements. These medications irritate the bowel lining, leading to increased motility and expulsion of stool. Examples of stimulant laxatives include bisacodyl and senna.

D) Bulk-forming laxative:
Bulk-forming laxatives, such as psyllium and methylcellulose, work by increasing the bulk and water content of the stool, which stimulates bowel movements. They do not directly irritate the bowel lining to promote peristalsis. Instead, they absorb water and swell in the intestines, creating a larger, softer stool that is easier to pass.

A. Metered-dose inhaler (MDI): MDIs deliver a specific dose of medication in aerosol form. They consist of a pressurized canister containing medication and a mouthpiece or mask for inhalation. Patients must coordinate inhalation with actuation to ensure proper medication delivery to the lungs.

B. Nebulizer: Nebulizers convert liquid medication into a fine mist that can be inhaled directly into the lungs. They are commonly used for patients who have difficulty using MDIs or require higher doses of medication. Nebulizers are often used in acute care settings or at home for patients with chronic respiratory conditions.

C. Hypodermic syringe: Hypodermic syringes are used for administering injections subcutaneously, intramuscularly, or intravenously. They are not used for inhalation medication administration.

D. Feeding tube syringe: Feeding tube syringes are used for administering liquid medications or enteral feeds through feeding tubes directly into the gastrointestinal tract. They are not used for inhalation medication administration.

E. Dry powder inhaler (DPI): DPIs deliver medication in powdered form, which is activated by the patient's inhalation. Unlike MDIs, DPIs do not require coordination between actuation and inhalation. Instead, patients inhale forcefully to disperse the medication into their lungs.
