Something for Sleep
A 61-year-old woman, three years post-menopause, takes warfarin for atrial fibrillation, metoprolol, atorvastatin, and sertraline 100 mg. She reports five to six hours of broken sleep, waking three or four times, "mind racing" at 2 a.m., daytime fatigue, 12 pounds of weight gain, and four or five night sweats. She says, "My friend takes kava and melatonin - just tell me what dose to take." She drinks two glasses of wine to wind down, has coffee until 2 p.m., naps about 90 minutes most afternoons, and provides five days a week of care for her mother, who has dementia. Her last INR was therapeutic.
1. How do you handle the supplement request in the moment?
Read the worked answer
I do not give a dose, and I say why in one sentence rather than a lecture.
- Be warm and specific, not vague. "I'm not going to give you a dose - not because I'm being cagey, but because with warfarin these aren't casual choices and I'm not the right person to make them."
- Flag the actual concerns at a level that is accurate without practicing pharmacy: kava is associated with hepatotoxicity and is a poor choice for anyone with liver risk factors or on multiple hepatically metabolized drugs; both kava and melatonin have been discussed in relation to bleeding risk and are not well studied in anticoagulated patients; her sertraline adds serotonergic and bleeding considerations. Valerian is another common sleep herb with the same interaction uncertainty.
- Redirect rather than refuse. "Ask your pharmacist or prescriber, and take the actual bottles in - not a photo of the label. Will you do that before you start anything?"
- Do not launder a recommendation through "my friend takes it." Social proof is not evidence, and my silence is easily heard as endorsement.
Scope reasoning: nurse coaching does not include prescribing, recommending supplement doses, or diagnosing a sleep disorder. The safe and genuinely helpful move is to route the question to the people who can answer it, then work on what is actually within my scope - which here is considerable.
2. Set your assessment and coaching priorities. What do you pursue first, and why not all of it at once?

Do a whole-person pass, then refuse to act on all of it.
Assess across domains:
- Physical: sleep pattern and timing, vasomotor symptoms, caffeine and alcohol timing, nap length, pain, medication timing (metoprolol and night waking), thyroid and anemia status already known to the care team.
- Mental/emotional: the 2 a.m. racing mind suggests cognitive arousal; screen for depression and anxiety, noting sertraline already indicates a history.
- Relational/caregiver: five days a week of dementia care is the load-bearing fact in this story and is likely upstream of the 2 a.m. wakefulness, the weight gain, and the wine.
- Environmental/spiritual: sleep environment, meaning and grief around the mother's illness, who supports her.
Priorities, in order:
- Alcohol. Two glasses to "wind down" metabolize overnight and produce exactly the 2 a.m. rebound awakening she describes. It is high-yield, client-controlled, and does not require anyone's permission. It is also the change she is most likely to resist, so it has to be explored rather than prescribed.
- The nap and the caffeine cutoff. Structural, concrete, easy to test, and framed as an experiment: "Would you be willing to try a 20-minute nap instead of 90 for one week and see what happens to the 2 a.m. waking?"
- Caregiver load. One question she has probably not been asked: "Who relieves you?"
Why not everything: seven simultaneous changes guarantee none of them. Offering a menu respects autonomy and produces better data than a compliance list. Refer for CBT-I as a first-line discussion with her prescriber, since it addresses the cognitive arousal directly.
3. What in this case is outside your scope, and how do you close the loop rather than simply mentioning it?
Read the worked answer
Out of scope here:
- Diagnosing insomnia disorder or sleep apnea. Her fatigue, weight gain, and fragmented sleep warrant a clinical conversation about screening; I raise it and route it, I don't settle it.
- Supplement selection and dosing, and any adjustment to warfarin, metoprolol, atorvastatin, or sertraline.
- Treating the vasomotor symptoms - that belongs to her prescriber, and it matters because her night sweats are a plausible independent cause of the awakenings.
- Depression treatment, though screening is within nursing practice.
Closing the loop - the part that separates coordination from a vague suggestion:
- Ask permission to communicate with her prescriber and pharmacist, and get a written release.
- Send a short factual note: sleep pattern, alcohol and caffeine timing, nap, night sweats, the supplement question, and what she has agreed to try.
- Ask her to report back what the pharmacist said, and put that on the agenda for the next session.
- Document all of it, including that the supplement question was referred rather than answered.
Judgment point: a coach who says "you should ask your doctor" and moves on has technically stayed in scope and practically abandoned the concern. The standard is warm handoff plus documented follow-up - and if she reports starting kava anyway, that goes to the prescriber the same day.
