What potential issue can arise from intravenous antibiotic administration?

The correct choice highlights a significant concern associated with intravenous antibiotic administration, which is the fear of needles. Many patients experience anxiety or phobia related to needles and injections, which can lead to avoidance of necessary medical treatments. This fear can complicate the administration of intravenous medications, as patients may become resistant to needles and stressful for both the patient and healthcare provider.

Understanding this concern is crucial in a clinical setting, as addressing a patient's fear and employing strategies to reduce anxiety can significantly improve the overall treatment experience and compliance with recommended therapies. Additionally, the fear of needles can also impact a patient’s willingness to follow through with follow-up treatments or care, which can compromise their overall health outcomes.

In contrast, other potential issues, such as slow absorption rates or the requirement for extensive patient compliance, are not primary concerns for intravenous administration, as the IV route provides rapid delivery of medications directly into the bloodstream. The effectiveness of intravenous antibiotics is typically superior to oral routes in serious infections where immediate therapeutic levels are essential, further distinguishing this answer from other options.
