In reviewing a plan of care for a patient exhibiting the symptoms of anaphylaxis, which of the following medications would be avoided?
Antihistamines
Vasodilators
Corticosteroids
Bronchodilators
The Correct Answer is B
A) Antihistamines:
Antihistamines are commonly used in the treatment of allergic reactions, including anaphylaxis. They work by blocking the effects of histamine, which is released during an allergic reaction, and can help alleviate symptoms such as itching, hives, and nasal congestion. Antihistamines are typically included in the treatment regimen for anaphylaxis but should not be relied upon as the sole treatment.
B) Vasodilators.
Vasodilators are medications that widen blood vessels, leading to a decrease in blood pressure. In the context of anaphylaxis, where blood pressure can drop precipitously due to systemic vasodilation, the use of vasodilators can exacerbate hypotension, potentially worsening the patient's condition. Therefore, vasodilators should be avoided in the management of anaphylaxis.
C) Corticosteroids:
Corticosteroids, such as prednisone or methylprednisolone, are used in the management of anaphylaxis to reduce inflammation and prevent late-phase allergic reactions. They are not typically used as first-line treatment during the acute phase of anaphylaxis but may be administered after initial stabilization to prevent recurrence of symptoms.
D) Bronchodilators:
Bronchodilators, such as albuterol, are used to relieve bronchospasm and improve airflow in conditions such as asthma and chronic obstructive pulmonary disease (COPD). While bronchospasm can occur during anaphylaxis, bronchodilators may still be used to address this symptom. However, they should be used cautiously, and their administration should not delay the administration of epinephrine, which is the primary treatment for anaphylaxis.

Correct Answer is D
Explanation
A) H2-receptor blockers:
H2-receptor blockers, such as ranitidine and famotidine, are used to reduce the production of stomach acid. While they can provide symptomatic relief for ulcers by reducing acid secretion, they do not directly treat the underlying cause of the ulcer, which is the H. pylori infection.
B) Antacids:
Antacids are medications that neutralize stomach acid and can provide temporary relief from ulcer symptoms such as pain and discomfort. However, they do not eradicate the H. pylori bacteria or address the root cause of the ulcer. Antacids only provide symptomatic relief rather than treating the infection.
C) Proton-pump inhibitors:
Proton-pump inhibitors (PPIs), such as omeprazole and pantoprazole, are potent acid-suppressing medications that are commonly used to treat ulcers and gastroesophageal reflux disease (GERD). While they can help in ulcer healing by reducing acid secretion and providing symptomatic relief, they are not effective in eradicating H. pylori infection. PPIs are often used in combination with antibiotics for H. pylori eradication therapy, but they are not the primary treatment on their own.
D) Antibiotics.
H. pylori (Helicobacter pylori) is a bacteria that commonly infects the stomach lining and is a major cause of gastric and duodenal ulcers. Antibiotics are the primary treatment for H. pylori infection. The antibiotics kill the bacteria, allowing the ulcer to heal. Common antibiotics used to treat H. pylori include amoxicillin, clarithromycin, metronidazole, and tetracycline.
Correct Answer is D
Explanation
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 per minute, and is not directly related to 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 gastrointestinal tract that propels food and waste materials through the digestive system. While peristalsis is an important aspect of digestion, it does not encompass the entire process.
C) "Neutralization by use of bicarbonate from pancreatic and biliary secretions."
This statement refers to the neutralization of acidic chyme from the stomach by bicarbonate ions released from pancreatic and biliary secretions in the duodenum. While this process is a part of digestion, it specifically addresses the regulation of pH rather than the breakdown of food molecules into absorbable forms.
D) "It is the process when food is broken down into molecules that can be absorbed."
This statement accurately describes digestion, which is the process by which complex food molecules are broken down into simpler forms (such as carbohydrates into sugars, proteins into amino acids, and fats into fatty acids and glycerol) that can be absorbed and utilized by the body. Digestion occurs in various stages along the gastrointestinal (GI) tract and involves the action of enzymes, acids, and mechanical processes to facilitate the breakdown of food into absorbable nutrients.
