SENTINEL U APS ADULT COMPLEX 2 EXAM PREP 2026 QUESTIONS WITH
VERIFIED ANSWERS DETAILED RATIONALES GRADED A+
Part I: Complex Medication Management & Pharmacology (Questions 1–20)
1. A patient with multiple chronic conditions is admitted with new-onset
confusion and a recent fall. During medication reconciliation, which action should
the nurse prioritize first to identify a potential iatrogenic cause?
A. Reviewing the patient's immunization history and allergy list.
B. Compiling a complete list of all prescription, over-the-counter, and herbal
supplements to screen for interactions and duplications.
C. Asking the patient to identify their primary care provider for records.
D. Scheduling a family meeting to discuss long-term care options.
Rationale: Complex adult encounters often involve polypharmacy. A
comprehensive medication reconciliation is the priority to identify potential drug
interactions, duplications, or adverse effects that could explain the new
symptoms.
2. A patient on a loop diuretic, ACE inhibitor, and potassium supplement reports
generalized weakness and palpitations. Which laboratory value should the nurse
review most urgently to assess for a common adverse effect of this regimen?
A. Serum sodium level.
B. Serum calcium level.
C. Serum potassium level.
D. Serum magnesium level.

,Page 2 of 66
Rationale: The combination of a loop diuretic (which causes potassium loss) and
an ACE inhibitor (which can increase potassium) creates a high risk for dyskalemia.
Weakness and palpitations are classic signs of hypokalemia or hyperkalemia, both
of which can cause fatal arrhythmias.
3. A patient is prescribed warfarin for atrial fibrillation. Which over-the-counter
medication should the nurse specifically instruct the patient to avoid without
consulting their provider due to a significant interaction risk?
A. Acetaminophen.
B. Ibuprofen (NSAID).
C. Diphenhydramine.
D. Artificial saliva.
Rationale: NSAIDs can potentiate the anticoagulant effect of warfarin and increase
the risk of gastrointestinal bleeding. Patients should be counseled to avoid them
or use them only under close provider supervision.
4. A patient with type 2 diabetes is started on a new medication. Which
instruction is most critical for the nurse to include regarding the risk of
hypoglycemia?
A. "Monitor your blood glucose closely, especially during periods of illness or if
you skip meals."
B. "You can adjust your own dose based on how you feel each day."
C. "This medication will cure your diabetes, so you can stop your other
medications."
D. "Take this medication only when you feel your blood sugar is high."
Rationale: Patient education for diabetes medications must emphasize the risk of
hypoglycemia, its recognition, and the importance of monitoring, especially during
stressors like illness or decreased oral intake.
5. A patient is receiving IV heparin. Which laboratory value is the most sensitive
indicator for monitoring the therapeutic effect of this medication?
2|Page
,Page 3 of 66
A. Prothrombin time (PT).
B. International normalized ratio (INR).
C. Activated partial thromboplastin time (aPTT).
D. Platelet count.
Rationale: The aPTT is the standard test used to monitor and titrate
unfractionated heparin therapy. The INR is used for warfarin monitoring.
6. A patient with a history of heart failure is prescribed a new medication. Which
class of medication requires the nurse to monitor for signs of digoxin toxicity?
A. Beta-blockers.
B. Angiotensin-converting enzyme (ACE) inhibitors.
C. Diuretics (especially loop and thiazide diuretics).
D. Statins.
Rationale: Diuretics can cause hypokalemia, which significantly increases the risk
of digoxin toxicity. The nurse must monitor potassium levels closely when these
medications are used together.
7. A patient is prescribed a high-alert medication. Which action is most essential
for the nurse to take to ensure patient safety during administration?
A. Verify the medication with a second nurse or use an automated verification
system.
B. Administer the medication as quickly as possible to avoid delays.
C. Prepare the medication in a common area to allow for observation.
D. Document the administration before giving the medication to save time.
Rationale: High-alert medications carry a heightened risk of significant patient
harm. Independent double-checks or bar-code verification are critical safety steps
to prevent administration errors.
8. A patient with a seizure disorder is prescribed phenytoin. Which instruction is
most important for the nurse to provide regarding oral care?
A. "Use a soft toothbrush to prevent gum irritation and bleeding."
B. "Floss your teeth vigorously to maintain gum health."
3|Page
, Page 4 of 66
C. "Rinse your mouth with hydrogen peroxide daily."
D. "Avoid brushing your teeth to prevent medication absorption issues."
Rationale: Phenytoin can cause gingival hyperplasia, making the gums tender and
prone to bleeding. Soft toothbrushes and gentle oral hygiene are essential to
prevent complications.
9. A patient is on long-term corticosteroid therapy. Which assessment finding is a
priority concern for the nurse to report?
A. Weight loss and hypotension.
B. Signs of infection, such as fever or delayed wound healing.
C. Polyuria and polydipsia.
D. Bradycardia and hypertension.
Rationale: Long-term corticosteroid use suppresses the immune system, masking
signs of infection. A fever or poor wound healing can indicate a serious, potentially
masked infection that requires urgent intervention.
10. A patient with depression is started on an SSRI. Which statement by the
patient indicates a need for further teaching about potential adverse effects?
A. "I know it might take a few weeks before I feel the full effect."
B. "I should report any new or worsening thoughts of self-harm immediately."
C. "If I miss a dose, I can just take two the next day to catch up."
D. "I might experience some nausea or headache when I first start taking this."
Rationale: Taking a double dose of an SSRI is not recommended and can increase
the risk of adverse effects, including serotonin syndrome. Patients should be
instructed to take the missed dose as soon as remembered unless it is almost time
for the next dose, and never to double up.
11. A patient is prescribed a new medication that is highly protein-bound. Which
concurrent condition would most increase the risk of drug toxicity?
A. Hypoalbuminemia.
B. Polycythemia.
