The nurse should be aware that Barrett's esophagus is a complication from what medical condition if left untreated?

Esophageal reflux

Eating hot and spicy food

Frequent episodes of vomiting

Esophageal polyps

Answer and Explanation

The Correct Answer is A

Choice A reason:

Esophageal reflux, or gastroesophageal reflux disease (GERD), can lead to Barrett's esophagus if left untreated. Chronic acid exposure from GERD causes changes in the esophageal lining, increasing the risk of developing Barrett's esophagus, a precancerous condition requiring monitoring and management.

Choice B reason:

Eating hot and spicy food may exacerbate symptoms of GERD but is not a direct cause of Barrett's esophagus. It can irritate the esophageal lining temporarily but does not lead to the cellular changes associated with Barrett's esophagus.

Choice C reason:

Frequent episodes of vomiting can damage the esophagus and lead to other complications but are not specifically linked to the development of Barrett's esophagus. The primary cause is chronic acid reflux rather than mechanical or chemical irritation from vomiting.

Choice D reason:

Esophageal polyps are growths that can occur in the esophagus but are not related to Barrett's esophagus. Barrett's esophagus results from prolonged acid exposure and cellular changes, whereas polyps are distinct growths that may require different monitoring and management strategies.

Correct Answer is C

Explanation

Choice A reason:

Platelets are involved in blood clotting and do not play a role in oxygen transport. Their primary function is to prevent bleeding by forming clots in damaged blood vessels.

Choice B reason:

Neutrophils are a type of white blood cell that helps fight infection. They are part of the immune system and do not transport oxygen.

Choice C reason:

Hemoglobin, a protein found in red blood cells, is responsible for transporting oxygen from the lungs to the tissues and carbon dioxide from the tissues back to the lungs. It binds with oxygen in the lungs and releases it in the body’s tissues, playing a critical role in respiratory gas exchange.

Choice D reason:

Lymphocytes are another type of white blood cell involved in the immune response. They do not carry oxygen but are vital for fighting infections and producing antibodies.

A. Simple face mask B. Venturi mask C. Non-rebreather mask D. Partial rebreather mask

Correct Answer is C

Explanation

Choice A reason:

A simple face mask provides moderate oxygen concentrations but lacks a one-way valve. It is suitable for delivering oxygen but does not meet the requirement for the highest concentration of oxygen with a one-way valve, which is crucial for preventing rebreathing of exhaled air.

Choice B reason:

A Venturi mask delivers precise oxygen concentrations and is useful for patients requiring controlled oxygen therapy. However, it does not provide the highest concentration of oxygen and does not have a one-way valve system to prevent rebreathing.

Choice C reason:

A non-rebreather mask is designed to deliver the highest concentration of oxygen available in a mask system. It includes a reservoir bag and a one-way valve that prevents exhaled air from mixing with the oxygen in the bag, ensuring that the client receives nearly 100% oxygen concentration.

Choice D reason:

A partial rebreather mask delivers high oxygen concentrations but allows some rebreathing of exhaled air due to the absence of a one-way valve. It is not the best choice for providing the highest concentration of oxygen with a one-way valve, which is necessary for certain medical conditions.
