Q

A 50 year male patient with a second-degree heart block (Mobitz Type I AV block), presents
his EKG report to the physical therapist. What would a physical therapist expect to find on his
EKG?
A. An increase in PR interval with no dropped beats
B. No relationship between P waves and QRS complexes
C. Normal PR intervals in all the beats preceding a dropped beat
D. A gradual increase in PR interval length in all the beats preceding a dropped beat

A

Correct Answer: D
Mobitz Type I AV block, also known as Wenckebach, presents with a gradual increase in PR
interval length in the preceding beats and then an eventual dropped beat. Option A. is a first
degree heart block, B. is a third degree heart block, C. is a second degree heart block Mobitz
Type II AV block.

Q

During a cardiac rehabilitation session, the PT notices that the ECG strip is displaying an
increased PR interval, while the rest of everything is normal. Which of the following would be
indicative of this findings?
A. First degree AV block
B. Second degree Mobitz Type II AV block
C. Third degree AV block
D. Second degree Mobitz Type I AV block

A

Correct answer: A
First degree heart block occurs when the conduction time through the A-V node is prolonged;
therefore, the ECG will have an increased length of the PR interval.

Q

A 50 year old male patient is performing a Bruce protocol in the clinic. During the protocol,
the PT sees the EKG as below. What does it mean and what should the PT do?

A) CVA causing a lateral medullary syndrome and the PT should stop the protocol and call 911
B) First degree AV block and the PT should continue the protocol
C) Myocardial Ischemia with ST segment depression of more than 2 mm and the PT should stop
the protocol
D) Myocardial Infarction with ST segment elevation greater than 1 mm and the PT should stop
the protocol

A

Correct answer: C
ST segment depression is seen with myocardial ischemia. The American College of Sports
Medicine recommends termination of test/exercise when the ST segment is depressed 2.0 mm
or more.

Q

Which anatomical structure is auscultated in the below image?

A) Apical Pulse
B) Aortic valve
C) Tricuspid valve

D) Pulmonic valve

A

Correct answer: A
The apex of the normal heart is in the fifth intercostal space at the midclavicular line. In a
healthy heart, this area, known as the apical pulse/ point of maximal impulse (PMI), is where
the contraction of the LV is most pronounced.

Q

A 45 year old male patient had an incident of uncomplicated myocardial infarction 6 weeks
ago. The patient was in cardiac rehab and now the PT has to give strength training to the
patient. Which is the MOST appropriate protocol that can be given to this patient?
A) Wait 2 more weeks for strength training
B) Start using 5 pounds free weights or dumbbells with UE and LE training
C) Use 5-10 pounds for UE and 10-15 pounds for LE
D) Exercise with light weights based on 30%–40% of the one-repetition

A

Correct answer: D
Participation in resistance training can begin a minimum of five weeks post MI including four
weeks of continuous program participation. Resistance exercise is traditionally prescribed based
on the individual’s measured or estimated maximal strength or the “one-repetition maximum.”
General strength prescription in cardiac patients involves 30%–40% of the one-repetition. The
patient can exercise with light weights and elastic bands.

Q

A physical therapist is designing exercise for a patient who is on beta blockers, which of the
following is NOT correct about the effect of beta blockers:
A) Decrease HR with exercise
B) Decrease contractility
C) Decrease myocardial oxygen demand
D) Increase afterload

A

Correct answer: D

Beta blockers decrease beta-sympathetic activity on the heart, resulting in a decrease in blood
pressure, HR and contractility and therefore reduced energy demand. Beta blockers do not
increase afterload.

Q

A 58 year old male patient in is phase II cardiac rehabilitation. On the initial examination,
the therapist noted that the patient is taking atenolol. Which of the following is the BEST
measure to monitor the patient’s exertion level while exercising?
A) Heart rate
B) VO2 max
C) RPE scale
D) Systolic blood pressure

A

Correct Answer: C
Atenolol is a beta blocker which is a category of drugs that block the sympathetic beta receptors
and decrease both resting HR and HR response to exercise. They are commonly used in the
treatment of angina pectoris, arrhythmias, and hypertension. Patients taking beta blockers
typically experience early fatigue with exercise; an alternative to HR monitoring, such as Ratings
of Perceived Exertion scale, should be considered to monitor exercise intensity.

Q

A 26 year old woman is diagnosed with a high risk pregnancy and is in her second trimester.
She would like advice on resting positioning from her PT. What is the most beneficial position
for this patient?
A) Supine
B) Right side-lying
C) Supine with head end of bed elevated to 20 degrees
D) Left side-lying

A

Correct answer: D
The position of choice for the high risk patient is left side-lying, which is optimal for reducing
pressure on the inferior vena cava and for maximizing cardiac output, thereby enhancing
maternal and fetal circulation.

Q

A 60 year old healthy male comes to the outpatient clinic for aerobic exercise program. On
examination, the resting heart rate of the patient is 70 bpm. Which of the following is the MOST
appropriate exercise intensity for this patient?
A. Exercise at 6-7 METs
B. Exercise at target heart rate of 115-133 beats/min
C. Exercise at 40% of HR max
D. Exercise at 85% to 95% of VO2max.

A

Correct answer: B
We can use Karvonen formula for calculating the target heart range. Karvonen formula (target
HR = [(HRmax – HRrest) × % intensity] + HRrest).
For moderate-intensity exercise, the CDC recommends that the target HR be 50% to 70% of
predicted HR maximum and for vigorous-intensity exercise, it should be 70% to 85%. Lower
exercise intensities are indicated for individuals with low fitness levels.
HRmax: 220-age i.e. 220-60=160
HRR= HRmax- HRrest, 160-70, i.e. 90
Intensity= 50%-70%
Using the formula, Target Heart rate= 90*(50%-70%)+70
50% intensity: 45+70=115

Q

A PT is conducting a 6MWT in a 50 year old male patient diagnosed with hypertension.
The patient uses quad cane for ambulation. Which of the following is not true regarding 6MWT?
A. The patient could walk as far as he can in a normal walking pace
B. Standardized encouragement is provided periodically by the PT
C. The patient could use his quad cane during the test
D. The time stops when the patient stops and rest

A

Correct answer: D
In the 6MWT, options A, B and C are all part of the protocol. In this test, the patients walk as far
as they can at their usual pace for 6 minutes while using their customary assistive devices and
orthotics. They can stop and rest as needed, but the stopwatch continues. Standardized
encouragement is provided periodically.

Q

Which of the following is the best measure to determine myocardial oxygen demand?
A) VO2 max
B) Rate Pressure Product
C) Heart rate reserve
D) Blood pressure

A

Correct answer: B
Myocardial oxygen demand (MVO2) is the energy cost to the myocardium. Clinically, MVO2 is
calculated as the product of HR and systolic blood pressure, known as the rate pressure product
(RPP) or double product. Any activity that increases HR and/or BP will increase MVO2.

Q

A 12 year old child presents in the emergency with burns to head, neck and anterior trunk.
What percentage of the child’s body is suffering from burns, based on Modified Lund and
Browder chart?
A. 26%
B. 16%

C. 31%
D. 35%

A

Correct answer: A
As per the Modified Lund and Browder chart for determination of percentage of body surface
area for burn in a 12 year old child; head- 11%, neck-2%, anterior trunk- 13%, so total burn
percentage is 26%.

18
Q

A patient with peripheral artery disease is starting a walking program using a treadmill.
The patient complains of moderate pain and reaches a 3 on the claudication scale. What is the
NEXT step the therapist should take?
A. Continue walking, pain is expected and a normal response
B. Stop exercise, sit patient down, continue walking when pain subsides
C. Continue exercising but slow treadmill speed to 1.0 mph
D. Stop walking, patient isn’t tolerating it well, use arm cycle ergometry instead

A

Correct Answer- B
Rationale: Walking programs are used for patients with peripheral artery disease and include
moderate intensity exercise. Patients should exercise to levels of maximal tolerable pain (3 out
of 4 in the claudication scale), in order to obtain optimal symptomatic benefit over time,
possibly through enhanced collateral circulation or increased muscular efficiency. So, the patient
should stop exercise and rest until the pain subsides and start again.

19
Q

A 50 year old male patient visited cardiac rehabilitation center with a diagnosis of
right heart failure. Which of the following is NOT commonly seen in right heart failure?
A. Abnormal heart sound
B. Peripheral edema
C. Pulmonary edema with dyspnea on exertion
D. Jugular vein distension

A

Correct Answer- C
Options A, B and D are commonly seen in right heart failure. Dyspnea is one of the most
common symptoms experienced with left-sided CHF. The SOB is associated with pulmonary
edema.

20
Q

A 25 year old female with supraventricular tachycardia has an exacerbation of her
symptoms due to anxiety related to exams. She asked her cardiologist for an alternate to the
beta blockers due to unfavorable side effects. The most appropriate intervention by
her cardiologist would be:
A. Calcium channel blockers
B. Anti-anxiety medication to relieve her exam induced stress
C. Carotid massage and valsalva maneuver
D. Increase the dose of beta blockers

A

Correct answer: C
Patients with SV-tach usually respond to a carotid massage where stimulation of the
baroreceptors within the carotid bodies of the carotid artery produce a parasympathetic
response. Other treatment interventions to reduce heart rate for patients with SV-tach include
coughing and breath-holding techniques achieved through the Valsalva maneuver. Each of these
techniques are geared to increase parasympathetic drive in different ways to reduce heart rate.

21
Q

A patient is exercising in a Cardiac Rehab Clinic, the physical therapist monitors the ECG
and notes the below changes. Which of the following is most likely diagnosis for this patient?

A. Trigeminy
B. Couplet
C. Bigeminy
D. Ventricular tachycardia

A

Correct answer: A
The PVC is called bigeminy when every other beat is a PVC, trigeminy when every third beat is a
PVC. The PVC is paired or a couplet if two PVCs are together, a triplet or ventricular tachycardia
(VTACH) if three are together in a row.
