Apixaban held on the PAUSE schedule, metoprolol continued, lisinopril and metformin held, glargine reduced and atorvastatin kept: this NU648 perioperative plan dates every decision for a composite colectomy patient.

What a finished NU648 Unit 4 perioperative medication plan looks like
Three pages, most of it a six-row table with columns for medication and indication, decision, last preoperative dose, restart timing, and source. Apixaban stops [two] days before the operation, a high-bleeding-risk procedure, with no heparin bridge and no preoperative coagulation test, following the PAUSE trial (Douketis and colleagues, JAMA Internal Medicine 2019). Metoprolol continues, with POISE (2008) cited for the harm of starting high-dose beta-blockade at surgery rather than for stopping it. Lisinopril is held the morning of surgery, a choice set against STOP-or-NOT (2024), which found no outcome difference either way. Metformin is held the day of surgery. Glargine drops to [80] percent the evening before, following the ADA Standards of Care. Atorvastatin continues throughout. A restart line places apixaban at [48-72] hours after surgery once bleeding risk allows.
How a NU648 Unit 4 example is structured
Risk sorts every row, and the plan names which risk it is sorting by: bleeding against clotting for the anticoagulant, hypotension against rebound for the cardiovascular agents, hypoglycemia against hyperglycemia for the diabetes medications. Naming each tradeoff separates the plan from a list of instructions. Apixaban receives the most space because it involves the most dates, and its bleeding-risk category and the patient's renal function justify the two-day interval. The absence of bridging is argued, with BRIDGE (2015) cited alongside PAUSE, since a reader might expect heparin coverage for a patient with atrial fibrillation. Where evidence is genuinely mixed, as with ACE inhibitors, the plan names the 2024 ACC/AHA perioperative guideline and the trial, then follows the surgical team's stated convention. Restart timing gets the same weight as stopping, because resumption is where postoperative plans most often lose track.
Apixaban by the calendar
A high-bleeding-risk colectomy and normal renal function give a last dose [two] days before surgery and a restart [48-72] hours after. The plan cites PAUSE for both intervals and for skipping a preoperative anticoagulant level.
No bridge, and why
BRIDGE found that heparin bridging in atrial fibrillation added bleeding without reducing clots. The plan uses that result, together with apixaban's short half-life, to explain why nothing replaces the anticoagulant during the gap.
Keep the beta-blocker
Metoprolol continues, morning dose included. POISE is cited for a narrower point than it is often used for: starting high-dose beta-blockade at surgery caused harm, which says nothing against continuing an established one.
Blood pressure agents, a stated judgment
Holding lisinopril reduces intraoperative hypotension in some studies, while STOP-or-NOT found no outcome difference. The plan records both, follows the surgical team's convention, and sets a restart condition based on pressure and creatinine.
Insulin and metformin on the day
Glargine at [80] percent the night before and metformin held that day limit hypoglycemia during fasting. Point-of-care glucose every [four to six] hours is scheduled, with a target range cited from the ADA Standards of Care.
Where marks go in NU648 Unit 4
A plan that holds everything, or continues everything, gets little credit however neat its table, because the assignment is the sorting. Apixaban stopped with no reference to bleeding category or renal function, or bridged with heparin by reflex, draws the most frequent correction. Beta-blockers held before surgery count as a real error, given the rebound risk. Restart timing left blank for any row makes the plan half a plan. Mixed evidence on ACE inhibitors presented as settled, in either direction, loses credit for accuracy. Insulin handled without a glucose monitoring plan looks incomplete, and metformin held for days without a reason looks cautious to the point of error. A row with no source, or a date written relative to nothing in particular, is a lesser slip.

Whatever the home list in your NU648 Unit 4 case, send it with the procedure, the patient data and the rubric. The plan sample, free the first time and delivered inside 24-48h, sorts each medication by the risk it carries around surgery, dates both the last dose and the restart, and attaches a source to every row.
NU648 Unit 4 questions, answered
What if the case uses warfarin instead of apixaban?
Warfarin changes the timeline and the monitoring. It is typically stopped about [five] days ahead with an INR check before surgery, and bridging becomes a genuine question for some patients, such as those with a mechanical mitral valve. The sample would cite the relevant guidance and apply the patient's thrombotic risk to the bridging decision.
Should herbal products and supplements appear in the plan?
If the patient takes any, yes. Several supplements affect bleeding or interact with anesthesia, and a complete home list includes them. The sample asks about them in the history, names any that should stop before surgery with the reason, and cites a recognized reference, since evidence for many products is limited.
Who actually decides which medications are held?
In practice, the surgical, anesthesia and prescribing teams within hospital policy. The coursework plan demonstrates the reasoning such a decision rests on, and its figures sit in brackets around an invented patient. It is not an order set, and no part of it applies to a real person without that team's review.
