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.
