What problem could result from sensor malfunctions in therapeutic devices?

Sensor malfunctions in therapeutic devices can lead to erratic behavior or inaccurate readings, which poses significant risks to patient safety and treatment efficacy. Therapeutic devices rely on sensors to monitor vital signs, administer medication, or adjust treatment protocols based on real-time data. When these sensors fail, they can provide false data or fail to respond appropriately, resulting in incorrect dosages or inadequate patient monitoring. Such inaccuracies could lead to severe consequences, such as under-treatment of a medical condition or adverse effects from excess treatment.

The other options do not reflect potential issues stemming from sensor malfunctions. Increased battery life may actually be a benefit rather than a problem, improved user interface and enhanced portability are typically features of a well-functioning device rather than complications arising from sensor errors. Thus, the correct answer highlights the critical nature of accurate sensor functioning in therapeutic equipment.
