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

A) The amount of blood pumped by the heart through the circulatory system in 1 minute.
This statement describes cardiac output, which is the volume of blood pumped by the heart in one minute. Cardiac output is not directly related to the process of digestion.

B) Smooth muscle movement of the GI tract by way of contractions.
This statement describes peristalsis, which is the rhythmic contraction of smooth muscles in the GI tract that propels food and digestive contents through the digestive system. While peristalsis is an essential aspect of digestion, it does not encompass the entire process.

C) Neutralization by use of bicarbonate from pancreatic and biliary secretions.
This statement describes the role of bicarbonate in neutralizing stomach acid in the small intestine. Bicarbonate is released from pancreatic and biliary secretions to neutralize acidic chyme from the stomach, creating a more favorable environment for digestive enzymes to function. While this is an important aspect of digestion, it does not fully encompass the entire process.

D) It is the process when food is broken down into molecules that can be absorbed.
Digestion refers to the process by which food is broken down into smaller molecules that can be absorbed and utilized by the body. This process occurs in the gastrointestinal (GI) tract and involves the mechanical and chemical breakdown of food into nutrients such as carbohydrates, proteins, and fats, as well as vitamins and minerals. These nutrients are then absorbed across the lining of the GI tract and transported to cells throughout the body for energy, growth, and repair.

A) Sedation:
Sedation is not an adverse effect commonly associated with oxymetazoline nasal spray. Oxymetazoline works by constricting blood vessels in the nasal passages to relieve congestion and does not typically cause sedation.

B) Constipation:
Constipation is not an adverse effect associated with oxymetazoline nasal spray. Constipation is more commonly associated with medications that affect the gastrointestinal system, such as opioid analgesics or certain anticholinergic medications.

C) Productive cough:
Productive cough is not an adverse effect commonly associated with oxymetazoline nasal spray. Productive cough refers to a cough that produces mucus or phlegm and is more often associated with respiratory infections or chronic respiratory conditions.

D) Nasal congestion.
Oxymetazoline (Afrin) is a nasal decongestant spray commonly used for the temporary relief of nasal congestion associated with allergic rhinitis or the common cold. However, if oxymetazoline nasal spray is used for more than 3 to 5 consecutive days, it can lead to rebound congestion, also known as rhinitis medicamentosa. Rebound congestion occurs when the nasal mucosa becomes dependent on the medication for vasoconstriction, and upon discontinuation, nasal congestion worsens. Therefore, prolonged use of oxymetazoline nasal spray can result in a worsening of nasal congestion as an adverse effect.
