Two identifiers, one patient: the HI150 Unit 4 master patient index exercise below confirms a duplicate, traces the registration search that created it and decides how the merge should run. Searches like "hi 150 unit 4 assignment example", "hi150 unit 4 sample" and "hi150 unit 4 example" land here.
What a finished HI150 Unit 4 master patient index exercise looks like
A comparison table of the two index entries opens the exercise: name, date of birth, sex, address, phone, the last four digits of the Social Security number where recorded, and encounter history. One entry reads Robert, the other Bobby; the dates of birth differ only by swapped day and month. A scoring paragraph weighs each field and concludes the entries are the same composite patient, with two independent identifiers agreeing. The root-cause section reconstructs the search at registration: a nickname typed into the name field and a date entered in the wrong order, so the existing record never appeared. The merge section names the surviving number, the retired number, who authorizes the merge after verification, and what happens to the laboratory results and consult note filed under the newer number. Prevention closes it.
How a HI150 Unit 4 example is structured
Candidate records usually arrive with the prompt, and the exercise answers in three moves: a determination, a cause and a correction. The comparison table comes first so the reader sees the evidence before any conclusion. The determination follows, distinguishing a duplicate, one person with two numbers, from an overlay, two people sharing one number, since the fixes differ sharply. The cause section places the error at a specific moment in the registration workflow and names the search practice that would have found the existing entry. The merge section runs in sequence: verification, authorization, choice of surviving number, movement of documents, notice to the systems and departments holding the retired number. A final paragraph proposes one control at registration and one detection routine in the department, each assigned to a role rather than to the department at large.
Evidence before verdict
Both index entries side by side, field by field, so the determination rests on visible data rather than on the writer's assertion.
Duplicate, not overlay
One person carrying two numbers, separated clearly from two people sharing one number, because each problem needs a different repair.
The search that missed
A nickname and a swapped date reconstructed at the registration desk, placing the error at the moment it was made.
Merge in sequence
Verification, authorization, the surviving number, documents moved, and every downstream system told which number was retired.
One control, one detection routine
A registration search practice and a department duplicate report, each owned by a named role rather than by the department in general.
Where marks go in HI150 Unit 4
Points most often disappear on a merge with no account of documents already attached, as if retiring a number made its laboratory results and notes follow on their own. Next is a cause stated as human error with no reconstruction of what the clerk searched and why it failed. Confusing a duplicate with an overlay costs heavily, since treating an overlay as a duplicate would push two patients' information further together. Deciding the match on name alone, while ignoring the date and identifier fields that settle it, drops points too. Merges authorized by nobody in particular read as incomplete. Prevention aimed at the coding desk, where the duplicate was noticed, misses the registration desk where it was created, a misplacement rubrics in this course regularly penalize.

HI150 Unit 4 questions, answered
What is the difference between a duplicate, an overlay and an overlap?
A duplicate is one person with two numbers in the same index. An overlay is two different people sharing one number, usually because a clerk selected the wrong existing entry. An overlap is one person carrying different numbers across facilities in a shared system. The example handles a duplicate and names the other two so the determination is visibly deliberate.
Which record number should survive a merge?
The example follows a common convention that the older number survives, since it usually carries the longer history, but facility policy decides and your scenario may state it. Whatever the rule, the exercise should name it, apply it, and describe how references to the retired number are redirected so no document is left pointing nowhere.
Can this exercise use data from my job?
Only in a form stripped of anything that identifies a real patient. The sample uses composite names, invented numbers and altered dates, and yours should too. Most sections supply practice records for exactly this reason. If you rely on a work example, describe the pattern of the error rather than the entries themselves, and keep every identifier out.
