At the start of each shift, I review the schedule and patient files to familiarize myself with any specific needs or potential issues. I ensure that all monitoring equipment is set up and functioning correctly ahead of time.

Once the patients start arriving, I stagger their setup times to allow me to focus on each individual’s needs without feeling rushed. I also make use of checklists and electronic health records to keep track of vital information and progress throughout the night. If any issues arise, like a patient experiencing discomfort with their equipment, I address it promptly while keeping an eye on the monitoring systems for other patients. This systematic approach ensures each patient receives attentive care, even during busy nights.”

23. How would you address a situation where a patient refuses to follow pre-study instructions?

Handling a patient’s refusal to follow pre-study instructions is more than just managing compliance; it’s about patient engagement and adherence to protocols that ensure accurate study results. This question delves into the ability to balance empathy with firmness, showcasing an understanding of the importance of these instructions for the patient’s well-being and the integrity of the study. It reveals problem-solving skills and the approach to patient education, which are crucial for maintaining the quality of care and data accuracy in sleep studies.

How to Answer: Emphasize your strategy for calmly and respectfully communicating the significance of following pre-study instructions. You might mention that you would first seek to understand the patient’s concerns or reasons for non-compliance, then provide clear, concise explanations about how their cooperation directly impacts their diagnosis and treatment. Highlight any techniques you use to build trust and rapport, such as active listening, reassurance, and offering practical solutions or alternatives to address their concerns.

Example: “I would start by calmly and empathetically discussing the importance of the pre-study instructions with the patient, explaining how they directly impact the accuracy and effectiveness of the sleep study. Sometimes patients are more willing to comply when they understand the ‘why’ behind the rules. If the patient still refuses, I’d try to identify any specific concerns or barriers they might have and see if there’s a way to address those directly—perhaps they have a fear or misunderstanding that can be clarified.

If they continued to refuse, I’d document their non-compliance and notify the supervising physician or the relevant team member to determine the best course of action. It’s important to respect the patient’s autonomy while also ensuring the integrity of the study. The goal is to find a balance between the two, ensuring the patient feels heard and supported, while also maintaining the study’s reliability.”
