When the nurse enters the room of a male client who was admitted for a fractured femur, his cardiac monitor displays a normal sinus rhythm (NSR), but he has no spontaneous respirations and his carotid pulse is not palpable. Which intervention should the nurse implement?

A) Correct- Zidovudine is an antiretroviral medication used in the treatment of HIV infection.

One of the potential side effects of zidovudine is hematological toxicity, including anemia (low red blood cell count) and neutropenia (low white blood cell count). The appearance of pinpoint, red, round spots on the skin could be indicative of petechiae, which are small hemorrhages caused by the leakage of blood into the skin. Petechiae can occur due to low platelet counts, a
component of the complete blood count (CBC). Monitoring the complete blood count is important for clients receiving zidovudine to identify any potential adverse effects on blood cell counts. Anemia and neutropenia can increase the risk of infection, bleeding, and other complications. Therefore, any changes in blood cell counts, including the presence of petechiae, should be reported to the healthcare provider for further evaluation and management.
B) Incorrect- This is used to assess allergic reactions and is not specifically related to the appearance of petechiae.
C) Incorrect- A skin biopsy is typically performed to diagnose skin conditions or diseases and is not the primary assessment to evaluate the cause of petechiae.
D) Incorrect- Electromyography is a diagnostic test used to assess muscle and nerve function and is not relevant to the appearance of petechiae associated with zidovudine use.

Emphysema is a chronic obstructive pulmonary disease (COPD) characterized by the destruction of lung tissue and loss of elasticity in the alveoli. This leads to poor gas exchange, specifically the reduced ability of oxygen to enter the bloodstream and carbon dioxide to be eliminated from the body. Impaired gas exchange can result in hypoxemia and hypercapnia, leading to symptoms such as shortness of breath, fatigue, and decreased exercise tolerance.

While self-care deficit, activity intolerance, and ineffective airway clearance are all potential complications associated with emphysema, impaired gas exchange is the priority due to its direct impact on the client's oxygenation and overall respiratory function.

Addressing impaired gas exchange and optimizing oxygenation is essential to support the client's respiratory health and prevent further complications. Management strategies for impaired gas exchange may include administering supplemental oxygen, implementing respiratory treatments to improve lung function, and providing education on breathing techniques and energy conservation.
