The nurse is about to administer a histamine 2-receptor antagonist to a patient with peptic ulcer disease. What is the primary purpose of this class of medication?

It reduces the amount of HCl secreted by the parietal cells in the stomach.

It destroys the microorganisms causing inflammation in the stomach.

It neutralizes hydrochloric acid (HCl) in the stomach.

It inhibits the action of acetylcholine by blocking parasympathetic nerve endings.

Answer and Explanation

The Correct Answer is A

Choice A rationale
Histamine H2-receptor antagonists, also known as H2 blockers, are medications that help reduce the production of gastric acid. They achieve this by blocking H2 receptors in the parietal cells of the stomach, which are responsible for secreting hydrochloric acid (HCl)12. This reduction in acid secretion can help treat conditions such as peptic ulcers, gastroesophageal reflux disease (GERD), and Zollinger-Ellison syndrome, which are all conditions that can be exacerbated by excessive stomach acid.
Choice B rationale
While H2 blockers do help manage the symptoms of peptic ulcer disease, they do not directly destroy the microorganisms causing inflammation in the stomach. The primary cause of peptic ulcers is a bacterium called Helicobacter pylori, and the treatment for an H. pylori infection typically involves a combination of antibiotics and proton pump inhibitors, not H2 blockers.
Choice C rationale
H2 blockers do not neutralize hydrochloric acid (HCl) in the stomach. Instead, they work by reducing the amount of acid produced by the stomach. Antacids, not H2 blockers, are the class of drugs that work by neutralizing stomach acid.
Choice D rationale
H2 blockers do not inhibit the action of acetylcholine by blocking parasympathetic nerve endings. Anticholinergic medications are the ones that work by blocking the action of acetylcholine, a neurotransmitter that transmits signals in the nervous system.

Correct Answer is D

Explanation

Choice A rationale
Offering the client oral fluids is important for hydration, but it is not directly related to the care of an indwelling urinary catheter. The UAP can offer fluids to the client, but this action is not specifically tied to the turning of the client or the care of the urinary catheter.
Choice B rationale
Feeding the client a snack is a task that the UAP may perform, but it is not directly related to the care of an indwelling urinary catheter. The UAP can provide a snack to the client, but this action is not specifically tied to the turning of the client or the care of the urinary catheter.
Choice C rationale
Assessing breath sounds is within the scope of practice for a nurse, not a UAP. While it’s important to monitor a client’s respiratory status, this action is not directly related to the care of an indwelling urinary catheter.
Choice D rationale
Emptying the urinary drainage bag is an appropriate action for the UAP to take each time the client is turned. This action helps to prevent infection, maintain accurate intake and output records, and ensure the comfort and dignity of the client.

A. Stabilize the cervical spine. B. Check for a pulse. C. Request an x-ray. D. Assess the respiratory rate. E. Examine the abdomen. F. Ensure the airway is patent.

Correct Answer is ["A","F"]

Explanation

Choice A rationale

Stabilizing the cervical spine is one of the first actions that should be taken during the primary survey of a trauma patient. This is to prevent any potential injury to the spinal cord, which could result in permanent paralysis.

Choice B rationale
Checking for a pulse is an important part of the primary survey, but it is not one of the first actions that should be taken. The first priority is to ensure that the airway is patent and the cervical spine is stabilized.

Choice C rationale
Requesting an x-ray is not one of the first actions that should be taken during the primary survey. The first priority is to assess the client’s airway, breathing, and circulation, and to stabilize the cervical spine.

Choice D rationale
Assessing the respiratory rate is an important part of the primary survey, but it is not one of the first actions that should be taken. The first priority is to ensure that the airway is patent and the cervical spine is stabilized.

Choice E rationale
Examining the abdomen is an important part of the secondary survey, which is conducted after the primary survey. The first priority during the primary survey is to assess the client’s airway, breathing, and circulation, and to stabilize the cervical spine.
Choice F rationale

Ensuring that the airway is patent is one of the first actions that should be taken during the primary survey. This is to ensure that the client is able to breathe effectively and receive adequate oxygenation.
