MCCQE Part I Exam Prep 2026 | 100 Questions, Answers &
Rationales | Graded A+
1. A 40-year-old male patient suffered a burn injury in a household accident. The
burns cover his face, neck, right upper arm, and upper trunk. The nurse is
using the rule of nines to estimate the total body surface area (TBSA) affected
by the burns to guide treatment planning. According to the rule of nines,
which area has the largest percent of burns?
Right thigh and penis
Upper trunk
Right upper arm and penis
Face and neck
2. Discuss the significance of absent breath sounds in the context of a patient
with viral pneumonia and intubation.
Absence of breath sounds indicates the presence of bronchospasm.
Absence of breath sounds suggests normal lung function in this
scenario.
Absence of breath sounds is a sign of effective ventilation.
Absence of breath sounds may indicate a pleural effusion or
pneumothorax, which can complicate the patient's respiratory
status.
3. Describe the role of Theophylline in the management of apnoea in infants.
Theophylline acts as a respiratory stimulant to help alleviate apnoea
in infants.
Theophylline is used to manage cardiac issues in infants.
Theophylline is primarily a sedative for infants.
, Theophylline is used to treat infections in infants.
4. A child who has an arterial blood gas that depicts respiratory acidosis will
show
pH is alkalotic, PaO2 is lowered and Pa CO2 is raised
pH is acidic, PaO2 is raised and PaCO2 is raised
pH is acidic, PaO2 is raised and PaCO2 is lowered
pH is acidic, PaO2 is lowered and PaCO2 is raised
5. A 35-year-old woman comes to the ED complaining of chest pressure. She
has had such episodes intermittently over the last 5 years, usually when
sleeping, but over the last year she has had more frequent severe symptoms
that are occasionally associated with severe migraine headaches. The pain is
midsternal and is described as pressure that extends as a band around her
chest. The ED physician is initially dubious that the pain is cardiac in origin,
because the woman has no coronary disease risk factors. An ECG, however,
shows 2mm ST-segment elevation and inverted T waves in leads V1 through
V5 and 1mm ST-segment depression in leads II, III, and aVF. Before the
cardiologist arrives in the ED, the patient's ECG has returned to normal. This
repeat normal ECG is obtained after the administration of aspirin,
nitroglycerin, morphine, and oxygen. Which of the following is most likely for
these findings?
Diffuse intimal thickening with focal areas of atherosclerotic narrowing
Plaque rupture and thrombus formation in the left anterior
descending artery
Intermittent thrombus formation and lysis in the right coronary artery
Transiently increased coronary vascular tone in the right coronary
artery
, Intermittent thrombus formation and lysis in the left anterior
descending artery
6. What is a common indicator of a positive result in a stress test for coronary
artery disease?
Decreased blood pressure
Normal heart rate response
Exercise-induced angina or ST-segment changes
Increased oxygen consumption
7. Mr. Jackle, 68 years old, is admitted with hypotension and respiratory distress
requiring intubation following a large ST elevation anterior lateral wall
myocardial infarction. Mr. Jackle will be monitored for signs of reinfarction.
Which one of the following lab tests would best indicate reinfarction?
Lactate dehydrogenase
Venous oxygen saturation
Creatinine kinase
Cardiac troponin
8. A child, admitted to an emergency department, is experiencing nausea and
vomiting, salivation, respiratory muscle weakness, and depressed reflexes an
hour after exposure to pesticides. Which medications should a nurse
anticipate administering to the child?
Epinephrine and naloxone (Narcan®)
Atropine and flumazenil (Romazicon®)
Epinephrine and digoxin immune Fab (Digibind®)
Atropine and pralidoxime (Protopam chloride®)
