A nurse in a long-term care facility is planning care for several clients. Which of the following activities should the nurse delegate to the licensed practical nurse (LPN)?

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 A rationale:

Lillian Wald is known for founding the Henry Street Settlement in New York and for her work in public health nursing and social reform, but she is not specifically associated with keeping records on sanitation techniques and their effects on health.

Choice B rationale:

Clara Barton is renowned for establishing the American Red Cross and her humanitarian efforts during the Civil War. While she contributed significantly to healthcare, her focus was not on keeping records on sanitation techniques and their effects.

Choice C rationale:

Florence Nightingale, the founder of modern nursing, is the nurse who kept records on sanitation techniques and their effects on health. She is known for her work during the Crimean War, where she improved sanitation and hygiene practices in healthcare settings, leading to significant improvements in patient outcomes.

Choice D rationale:

Mary Nutting was an influential figure in nursing education, but she is not primarily recognized for keeping records on sanitation techniques and their effects. Her contributions were more related to curriculum development and nursing education.
