The nurse is assessing a 4-year-old client with eczema. The child's skin is dry and scaly, and the parent reports that the child frequently scratches the lesions on the skin to the point of causing bleeding. Which guideline is indicated for care of this child?

Rationale

A. Nausea and headache are common side effects of linezolid. While they can impact the client's comfort and adherence to treatment, they are generally not considered urgent or life-threatening unless severe or persistent.

B. Watery diarrhea is a significant concern with linezolid therapy, as it can indicate the development of Clostridium difficile infection (CDI) or other types of antibiotic-associated diarrhea. CDI is a severe condition that requires prompt treatment to prevent complications such as dehydration, colitis, and potentially life-threatening outcomes like toxic megacolon.

C. Increased fatigue can be a nonspecific symptom and may result from various factors, including the underlying illness (nosocomial pneumonia), medication side effects, or the stress of hospitalization. While it should be monitored, it is typically not an immediate concern unless accompanied by other concerning symptoms.

D. Yellow-tinged sputum can indicate the presence of infection or inflammation in the respiratory tract, which is relevant in the context of nosocomial pneumonia. It could suggest a worsening of the pneumonia or a new infection. However, it is not typically directly associated with linezolid therapy itself.

Rationale

A. A. lung biopsy involves obtaining a tissue sample from the lung for microscopic examination. It is typically performed to diagnose conditions such as lung cancer or to investigate unusual findings seen on imaging studies. However, for a client with COPD experiencing increased shortness of breath, a lung biopsy is not typically indicated as a first-line investigation. It is more invasive and usually reserved for specific diagnostic purposes other than routine evaluation of COPD symptoms.

B. Antibody testing is used to detect antibodies specific to certain infections or autoimmune conditions. It is not typically used in the routine evaluation of COPD symptoms unless there is suspicion of a specific autoimmune or infectious cause contributing to exacerbations, which is less common in COPD compared to other conditions.

C. A. sweat test is used to diagnose cystic fibrosis (CF), a genetic disorder that affects the lungs and digestive system. It measures the amount of chloride in sweat, which is elevated in individuals with CF. Since COPD and CF are distinct conditions with different underlying causes and diagnostic criteria, a sweat test is not appropriate for evaluating COPD symptoms.

D. Spirometry is the most appropriate test to schedule for evaluating a client with COPD who reports increased shortness of breath with activity. Spirometry measures lung function by assessing how much and how quickly a person can move air into and out of their lungs. It provides valuable information about the severity of airflow limitation, which is characteristic of COPD.
