PCCN Exam prep practice Questions
and All Correct Answers 2025-2026
Updated.
1. A 49-year-old male was recently admitted with an inferior wall
MI resulting from 100% occlusion of the right coronary artery
(RCA). The 12-Lead ECG reveals ST elevation in leads II, Ill, and avF.
You would expect to see reciprocal changes in which leads?
A. I, aVR
B. V, V2
C. V, VA
D I, aVL - Answer 1. D. I, aVI. The RCA perfuses the inferior wall and the mirror image or
reciprocal change will be seen in the high latera wall, which is reflected in leads I, and aVL, on
the 12-Lead ECG. Leads V1 and V2 correlate with the septal area, leads V3 and V4 correlate
With the anterior area of the heart. The aVR lead does not provide much diagnostic value as all
energy is depolarizing away from this lead.
You are summoned to the room of a 30-year-old female who is experiencing sustained tonic-
clonic convulsions while sitting in a chair. A family member states: "She was just talking to us
and suddenly she let out a shriek and started flopping like a fish out of water." What is your
initial priority of care?
A. Call for help and safely guide the patient to the floor
B. Call for help and administer a prescribed antiepileptic
C. Call for help and administer a prescribed benzodiazepine
D. Call for help and monitor the course of the seizure - Answer A. Call for help and safely
guide the patient to the floor
Patient Safety is priority
A 46-year-old patient presents with pneumonia and sepsis.
He was treated with 4 days of antibiotics and IV fluids. He is increasingly short of breath and is
now on 100% FiO, via non-re-breather mask. You obtain an ABG with the following results: pH
7.20 / PaCO, 68/ PaO, 102/ HCO, 28. A chest x-ray reveals bilateral pulmonary infiltrates. The
patient is likely developing:
A. Worsening pneumonia
B. Acute Respiratory Distress Syndrome
C. Pulmonary embolus
D. Atelectasis - Answer B. Acute Respiratory Distress Syndrome
,A 56-year-old male is admitted to the PCU with a hypertensive crisis. His blood pressure is now
205/125 mm Hg and he is complaining of a headache with nausea. He reports he ran out of
blood pressure medication three days ago, but also appears to be confused to the date and
situation. What is the most appropriate treatment approach?
A. Rapidly lower the systolic pressure to 100 mm Hg with IV antihypertensive medication, then
gradually reduce the diastolic pressure to 85 mm Hg with oral antihypertensive medications
B. Slowly lower the systolic pressure to 120 mm Hg with IV antihypertensive medications, then
switch to oral antihypertensive medications for maintenance
C. Rapidly lower the diastolic pressure to 100 mm Hg with IV antihypertensive medications, then
continue to gradually reduce the diastolic pressure to 85 mm Hg with oral antihypertensive
medications
D. Slowly lower the diastolic pressure to 85 mm - Answer C. Rapidly lower the diastolic
pressure to 100 mm Hg with IV antihypertensive medications, then continue to gradually reduce
the diastolic pressure to 85 mm Hg with oral antihypertensive medication
5. Which of the following labs must be closely monitored when administering Lisinopril to a
patient with systolic heart failure?
A. Sodium
B. Phosphate
C. Magnesium
D Potassium - Answer D. Potassium
Patients taking angiotensin converting enzyme inhibitors may experience hyperkalemia. ACE
inhibitors block angiotensin II, which may lead to decreased aldosterone. Aldosterone is
responsible forexcreting potassium from the kidneys. Therefore, ACE inhibitors can cause
potassium retension and potassium levels should be monitored closely. In addition, renal labs
such as BUN and creatinine should be monitored. If the patient develops more than a 20%
increase in the creatinine, the medication should be discontinued.
A 57-year-old man was admitted with an acute myocardial infarction and is rapidly
deteriorating. He has a BP of 86/42
(57), heart rate of 110, weak, thready pulses, and mottled skin-especially at the knees. He has
had minimal urine output the past 8 hours. A Rapid Response is activated. Which of the
following medications would be the best option to increase the patient's cardiac output?
A Dobutamine
B Norepinephrine
C Amiodarone
D Phenylephrine - Answer A Dobutamine. Dobutamine is a positive inotropic medication
used to improve myocardial dysfunction on patients with a low cardiac index and elevated
, afterload. It will improve contractility and reduce afterload. Milrinone, which is a
phosphodiesterase inhibitor could also be used as an alternative to dobutamine, in the setting
of decompensated heart failure. It is used cautiously in patients experiencing cardiogiogenic
shock as one of the main side effects of Milrinone is hypotension. The half life of Milrinone is
about 6 hours. Norepinephrine and Phenylephrine cause vasoconstriction, which would
increase the SVR and may compromise cardiac output.
You are caring for a patient post gastric bypass. Which of the following parameters should you
closely monitor after surgery?
A* HR, RR, temperature, WBC & MAP
B* Protein levels and vitamin B12
C* Albumin and pre-albumin levels
D* Signs of dumping syndrome - Answer A* HR, RR, temperature, WBC & MAP
You are caring for a patient admitted after a ground level fall. The patient has decreased level of
consciousness. On admission the patient is ordered to be a full code. The family arrives with
advanced directives stating the patient wishes not to have CPR performed or life sustaining
treatment continued. The nurse approaches the provider about this discrepancy and the
provider states "I am aware of the advanced directive, but the daughter wants everything
done."
What is the appropriate next step by the nurse?
A* Ask the daughter why she wants everything done
B* Collaborate with the provider and social worker to schedule a family meeting
C* Tell the doctor we have to follow the patient's wishes
* Discuss the situation with the nurse manager - Answer B* Collaborate with the provider
and social worker to schedule a family meeting
Which is the best intervention to promote safety of the patient receiving hemodialysis?
A* Direct visualization of the connection between the machine and the access device
B* Strict intake and output monitoring
C* Strict bedrest
D* Electrolyte assessment q 4 hours - Answer A* Direct visualization of the connection
between the machine and the access device
