PCCN EXAM|VERIFIED QUESTIONS AND CORRECT DETAILED
ANSWERS|RATED AND GRADED A+ NEW UPDATE| 2026/2027
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
The nurse must be able to visualize the junction of the central venous access and the dialysis unit at all
times. Disconnection can result in exsanguination within minutes.
Four hours after starting an insulin infusion in a patient admitted with diabetic ketoacidosis, the
patient's blood glucose is 235 mg/dL. Which of the following fluids should be administered at this point?
A Hypertonic solution to hydrate the cell
B D5.45 or D NS with a glucose source
C Isotonic saline bolus to maintain extracellular hydration
D Hypotonic saline to provide cellular hydration - ANSWER✔ B D5.45 or D NS with a glucose source
Dextrose should be included in IV fluids since the glucose has dropped below 250. This is done to
prevent hypoglycycemia.
11. A 45-year-old male is admitted to 1500m With Severe sepsis.
You are administering lactated ringers 500 ml IV boluses. A central line has been placed. Which of the
findings below indicate the fluid boluses are having its intended effect?
A* MAP of 55 mm Hg
B* ScvO, of 52%
