A client presents to the emergency room reporting sudden, sharp pain on the right side of the chest and shortness of breath. The right side of the chest is not moving with inspiration. The client's trachea is deviated towards the left: there is absence tactile fremitus on the right side of the chest. Upon percussion, the nurse hears hyperresonant sound on the right side of the thorax. Upon auscultation, no breath sounds are heard on the right. Which disorder would the nurse suspect?

The correct answer is choice B. Increased anteroposterior diameter of the chest.

Choice A rationale:

Petechiae on the chest (Choice A) are tiny red or purple spots that appear on the skin due to small blood vessel breakage. They are not typically associated with COPD and emphysema. Petechiae are more often related to conditions like thrombocytopenia or certain infections, where blood clotting is impaired.

Choice B rationale:

Increased anteroposterior diameter of the chest, often referred to as "barrel chest," is a characteristic finding in clients with COPD and emphysema. This occurs due to the hyperinflation of the lungs and the loss of elasticity in the lung tissues, which causes the chest to become rounded and the ribs to be positioned more horizontally.

Choice C rationale:

An oxygen saturation level of 96% (Choice C) is within the normal range for oxygen saturation. However, while it's important for clients with COPD to maintain adequate oxygen levels, this value doesn't specifically correlate with the client's symptoms of a wet cough and occasional shortness of breath.

Choice D rationale:

Respiratory alkalosis (Choice D) involves an increase in blood pH due to decreased levels of carbon dioxide (hypocapnia) caused by hyperventilation. While respiratory alkalosis can occur in clients with COPD due to compensatory hyperventilation, it is not a direct assessment finding related to the client's symptoms of a wet cough and occasional shortness of breath.

Choice D rationale:

This statement by an assistive personnel (AP) indicates a need for further teaching. Hand hygiene is crucial to prevent the transmission of microorganisms, and it involves both handwashing and the appropriate use of gloves. Changing gloves between clients is important to prevent cross-contamination, but it doesn't replace the need for handwashing. Hands can become contaminated even with the use of gloves, and proper hand hygiene should be practiced before and after glove use.

Choice A rationale:

The statement about using alcohol-based hand products after most client contact is accurate. Alcohol-based hand sanitizers are effective in reducing the number of microorganisms on the hands when soap and water are not readily available. They are especially useful in healthcare settings.

Choice B rationale:

Washing hands before providing client care is a fundamental principle of infection control. It helps remove dirt, debris, and transient microorganisms from the hands, reducing the risk of infection transmission.

Choice C rationale:

The statement about not wearing artificial nails when providing client care is correct. Artificial nails can harbor microorganisms and are challenging to clean thoroughly. They pose an infection risk and are generally not recommended for healthcare workers who provide direct patient care.
