PCCN practice Questions Exam Questions
And Answers
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?
