Three Decisions for Posttraumatic Stress After a Highway Crash: A Decision Tree Case in Which the Second Choice Causes the Third Problem
The Case
A composite woman in her mid-forties, a school bus driver, was the driver in a highway crash eleven months ago in which the other driver died. She meets criteria for posttraumatic stress disorder: intrusive memories, avoidance of highways and news reports, irritability, poor concentration and nightmares of the crash three to four nights a week. She has started trauma-focused psychotherapy but finds it hard to attend sessions consistently because of her work schedule, and she asks about medication. She has mild hypertension treated with a diuretic. The case is laid out as three decision points; each gives the options, the choice, the reasoning and the result that the next point responds to. No doses are given; reasoning stays at the level of drug class and mechanism.
Decision Point 1: Choosing a First Medication
Options: two selective serotonin reuptake inhibitors and one serotonin-norepinephrine reuptake inhibitor, each with some trial evidence in posttraumatic stress disorder. Choice: a selective serotonin reuptake inhibitor with a guideline recommendation for this condition. Reasoning: current clinical practice guidance recommends individual trauma-focused psychotherapy as the first-line treatment and, for pharmacotherapy, identifies specific serotonergic agents from these two classes as options (Department of Veterans Affairs & Department of Defense, 2023). The mechanism, serotonin transporter inhibition with slower downstream changes in fear-related circuits, predicts benefit over weeks rather than days (Stahl, 2021). The serotonin-norepinephrine option was set aside because its noradrenergic action can raise blood pressure, a consideration in a patient already treated for hypertension. Encouragement to continue psychotherapy remained part of the plan. Result at twelve weeks: intrusive memories and irritability are clearly reduced, and her PCL-5 score has fallen, but nightmares continue at about the same frequency, and she is sleeping badly before early shifts.
Decision Point 2: Nightmares That Did Not Respond
Options: add an alpha-1 adrenergic antagonist taken at night; refer for a nightmare-focused psychotherapy such as imagery rehearsal; or wait longer on the current medication. Choice: add an alpha-1 adrenergic antagonist at night, with a referral for nightmare-focused therapy once her schedule allows. Reasoning: nightmares in posttraumatic stress disorder are thought to involve heightened noradrenergic activity during sleep, and blocking alpha-1 receptors dampens that arousal (Stahl, 2021). The evidence is mixed, and the case says so: earlier small trials suggested benefit, but a large trial in military veterans with chronic posttraumatic stress disorder found that an alpha-1 antagonist was no better than placebo for distressing dreams or sleep quality (Raskind et al., 2018). The choice was made with her informed agreement that the benefit was uncertain. Predicted adverse effect, recorded in advance: dizziness on standing, from reduced vascular tone, made more likely by her diuretic. She was taught to rise slowly at night and to report lightheadedness. Result at six weeks: nightmares are somewhat less frequent, and she reports dizziness when she gets up at night.
Decision Point 3: A Fall at Night
Event: she fell getting up to use the bathroom at 0300, bruising her hip; she did not lose consciousness. Orthostatic vital signs at the next visit show a clear drop in systolic pressure on standing. Options: continue with more caution; stop the alpha-1 antagonist; or request that her primary care clinician reconsider the diuretic. Choice: stop the alpha-1 antagonist, inform her primary care clinician of the fall and the orthostatic findings, and move nightmare-focused psychotherapy forward as the main approach to the remaining nightmares. Reasoning: the fall is the adverse effect that the mechanism predicted, made more likely by the combination with her diuretic, and it outweighs an uncertain benefit for a woman whose job requires her to be alert and uninjured. The serotonergic antidepressant continues, since it is producing clear benefit.
What the Tree Shows
The second decision was reasonable when it was made, and its predicted risk was recorded and taught. The tree shows why that matters: when the fall occurred, the explanation was already written down, and the response was quick. It also shows the value of recording mixed evidence as mixed. Because the case never claimed the alpha-1 antagonist would work, stopping it was not a failure of the plan but the plan working as designed. The remaining symptom returns to the treatment with the strongest recommendation, psychotherapy (Department of Veterans Affairs & Department of Defense, 2023).

Reading the NURS 6630 Week 5 instructions
Decision tree prompts in this course usually present a patient and ask you to make a series of treatment decisions, each responding to the patient's result from the previous one, with rationale based on mechanism and evidence. Many sections provide the options at each point and the outcomes. Papers typically run three to four pages. At each decision, state the options, your choice and why, and the predicted benefits and risks. When evidence is mixed, say so. Include non-drug treatments where guidelines recommend them, and keep the reasoning at class level unless your prompt asks for more. If the prompt supplies outcomes, use them exactly.
Inside the NURS 6630 Week 5 example
The case section sets the scene, symptoms, psychotherapy access and her diuretic. Decision 1 compares serotonergic options, chooses one with guideline support from the VA/DoD guideline and explains why a noradrenergic option was set aside for her blood pressure, ending in a partial result. Decision 2 compares an alpha-1 antagonist, nightmare-focused therapy and waiting, chooses the medication with her informed agreement, cites a large negative trial and records the predicted dizziness. Decision 3 responds to the fall with orthostatic findings and stops the medication. A closing section explains why recording mixed evidence made stopping straightforward. Her informed agreement to an uncertain option is recorded at the second point, and her primary care clinician is told about the fall.
NURS 6630 Week 5 rubric: what earns full marks
Decision tree rubrics generally score the logic connecting decisions, pharmacologic rationale at each point, attention to evidence quality, safety and monitoring, integration of non-pharmacologic care and presentation. Logic earns the most credit when each decision clearly answers the previous result. Rationale is judged on mechanism and fit to the patient. Evidence quality rewards honest statements about mixed or negative trials. Safety rewards predicted adverse effects that are recorded and acted on. Integration rewards psychotherapy placed where guidelines put it. Presentation checks that options, choices and results are easy to follow. Some rubrics also reward recording the patient's informed agreement when evidence is uncertain, since that is part of good prescribing. Communication with other prescribers about adverse events is often credited as well.
Common NURS 6630 Week 5 mistakes, and how to avoid them
The most common loss is a set of decisions that ignore each other, as if each were a separate case. Another is presenting an add-on medication as proven when trials disagree. Some papers predict no adverse effects, or predict them and then forget them. Others leave psychotherapy out of a condition where it is first-line. Make each branch end with a result, cite the strongest guideline and the most important trial, record what you expect to go wrong and show that the plan changes when it does. Also check that each branch's result is the starting point for the next decision.

NURS 6630 Week 5 questions, answered
Why does each branch end with a result?
Because the next decision has to answer it. The example writes the outcome of each choice, partial response, then persistent nightmares, then a fall, as the evidence the following branch works from. Without those results the tree would be three unrelated decisions. That dependency is what graders this week hunt for, and your own case will supply its own sequence.
Why is the evidence for the second choice called mixed?
Because the trials testing an alpha-1 antagonist for trauma-related nightmares have not agreed, and the example reports that honestly instead of presenting the addition as proven. Acknowledging uncertainty where it exists earns accuracy credit in this course. The case still argues the choice from mechanism and from the patient's specific complaint, stating why it was worth trying.
Are doses given at any branch?
No. Each branch names a class and its receptor action, the reasoning, and what the record monitors, but no amounts, timing or target figures appear anywhere, here or in the sample. The week grades reasoning, not dosing. Prescribing detail is learned from drug references and precepted practice, never from a sample.
Where can I find a free NURS 6630 Week 5 sample paper?
All three decision points and the closing discussion are available here at no charge. A tree built on your own section's case is available from the desk.
Why does the NURS 6630 case keep psychotherapy in the plan?
Because guidelines recommend trauma-focused psychotherapy as first-line treatment for posttraumatic stress disorder, and medication is added alongside it rather than instead of it.
