A nurse on the Cardiovascular unit is completing the patient's history and physical examination. Which of the following information provided by the patient should the nurse consider as subjective data?

Choice A rationale:

Applying petroleum jelly to the nares is not necessary in this situation. Oxygen therapy through a nasal cannula aims to deliver oxygen to the client's respiratory system. Applying petroleum jelly might interfere with the oxygen delivery and is not a standard practice.

Choice B rationale:

Removing the nasal cannula while the client eats reduces the oxygen supply during a time when the body's oxygen demand might increase due to the digestive process. It's important to maintain consistent oxygen therapy, even during meals.

Choice C rationale:

Attaching a humidifier bottle to the base of the flow meter is not necessary for oxygen therapy at 5 L/min via nasal cannula. Humidification is usually needed at higher oxygen flow rates to prevent drying of the mucous membranes.

Choice D rationale:

Securing the oxygen tubing to the bed sheet near the client's head is the correct action. This ensures that the tubing is not pulled or tugged during movement, maintaining a steady flow of oxygen. Placing it near the client's head prevents kinking or tangling of the tubing and allows the client to move without disrupting the therapy.

Choice A rationale:

The choice "Pigeon" is not the correct answer. Pigeon chest, also known as pectus carinatum, is a deformity of the chest characterized by a protrusion of the sternum and ribs. This condition is not associated with chronic bronchitis.

Choice B rationale:

The choice "Funnel" is not the correct answer. Funnel chest, or pectus excavatum, is a deformity where the sternum is sunken into the chest. It is not the expected chest shape in chronic bronchitis.

Choice C rationale:

The choice "Kyphotic" is not the correct answer. Kyphosis refers to an excessive outward curvature of the thoracic spine, leading to a rounded upper back appearance. This is not the typical chest shape seen in chronic bronchitis.

Choice D rationale:

The correct answer is "Barrel." Choice D is the correct answer. Chronic bronchitis is a type of chronic obstructive pulmonary disease (COPD) characterized by airway inflammation and narrowing. Over time, this can lead to air trapping in the lungs and an increase in the anteroposterior diameter of the chest. This results in a barrel-shaped chest appearance, where the chest appears rounded and the ribs are more horizontal. This adaptation allows for increased lung capacity to accommodate for the compromised airflow in patients with chronic bronchitis.
