Night-Shift Nurse With Low Confidence and a History of Quitting
Denise, 38, is an ICU nurse on rotating 12-hour night shifts (three nights on, four off) and a single mother of two. She has had type 2 diabetes for four years; her latest A1c is 8.6%, BMI 36, and she takes metformin 1,000 mg twice daily. Her physician wrote 'exercise 150 min/week' on the referral. She has bought three gym memberships in four years and used each fewer than five times. She says she is 'all or nothing' and quit a boot camp after two weeks because she was 'the slowest one there.' On a 0-10 scale she rates importance of exercise 9 and confidence 2. She says, 'I know it matters, but between nights and the kids I don't have time, and I feel guilty even talking about it.' She has no chest pain, but reports fatigue and blurred vision when her glucose runs high. She wants you to 'just tell me what to do.'
1. Where is Denise in the transtheoretical model, and what does that imply for your first two sessions? Justify your answer with evidence from the setup.

She is in contemplation: she acknowledges the importance of exercise and is talking about it, but she is not taking sustained action and has a history of starting and quitting quickly. The high importance score (9) combined with very low confidence (2) is the key pattern. The work is not more education about diabetes; she already knows. The work is building confidence and resolving ambivalence.
First two sessions should therefore:
- Build alliance and ask what matters to her (being present for her children, not feeling defeated).
- Explore the all-or-nothing pattern without judging it; ask what happens internally when she misses a session.
- Avoid setting the full 150-minute target immediately. Negotiate a minimum dose she rates at least 7/10 confidence.
- Identify one or two small experiments, such as a 10-minute walk after a night shift or stairs at work.
- Affirm that her past attempts show she cares, not that she fails.
Her blurred vision with hyperglycemia also warrants encouragement to get a retinal exam before vigorous activity. If guilt or low mood is prominent, screen and refer rather than counseling beyond scope.
2. Write a motivational-interviewing response to 'I don't have time' that avoids the righting reflex and builds confidence, then propose a first-month plan.

Response: 'You are working 12-hour nights and raising two kids, so adding a gym plan feels like one more thing you will fail at. You still rated this a 9 in importance. What would a version look like that fits the life you actually have, not the one the gym assumes?' Then: 'On a scale of 2 to 10, what would move you from 2 to 3?' and 'What has worked before, even for a week?' This avoids arguing, affirms her reality, and evokes her own solutions.
First-month plan:
- Weeks 1-2: two 10-minute walks on shift days (break or after shift) plus one 15-minute family walk. Choose the days in advance.
- Weeks 3-4: add a third short walk only if confidence is at least 5. Use 'never miss twice' rather than perfection.
- Keep sessions short and scheduled around sleep. A phone reminder and a visible calendar help.
Coordinate with her diabetes team: metformin alone carries low hypoglycemia risk, but she should check glucose if she feels shaky. Blurred vision needs an eye exam before vigorous exercise. The target is consistency, not 150 minutes in month one.
3. What outcomes would you track, and how would you coordinate with her diabetes care team?
Read the worked answer
Track process outcomes first: sessions completed, minutes walked, confidence rating, and whether the plan felt doable. Weight and A1c are secondary and should not be the weekly feedback loop, because early scale changes can undermine confidence.
Also monitor steps, BP, sleep, and any glucose symptoms. Review at two weeks and six weeks. If she misses sessions, ask what got in the way rather than scolding; missed sessions are data about the plan, not evidence of character.
With a signed release, send the activity plan and any glucose symptoms to the diabetes educator or physician. Ask about metformin timing around night shifts and whether retinal screening is current. Do not change medication, prescribe a diabetes diet, or interpret A1c beyond the referral. If A1c remains high or blurred vision persists, reinforce medical follow-up. The counseling goal is to make the next action small enough that she can succeed and attribute the success to herself.
