Which of the following will determine aortic pulse pressure.
a. systolic + systolic + diastolic/3
b. diastolic + pulse pressure/3
c. systolic pressure - diastolic pressure
d. stroke volume x heart rate x 10.
Give this one a try later!
Aortic pulse pressure is just the difference between systolic and diastolic
pressure, so ANSWER is C
A unilateral wheeze would most likely indicate which of the following.
a. Asthma
b. Atelectasis
c. Foreign body aspiration
d. Epiglottitis
,Give this one a try later!
You wouldn't have asthma on just one side (unilateral), atelectasis would
cause diminished breath sounds, with epiglottitis you would get stridor,
since you are only hearing wheezing on one side, you are hearing it on the
side where you aspirated something,
so ANSWER is C
What should you recommend FIRST for a patient with multifocal pvc's
a. Administration of lidocaine
b. Administration of 100% oxygen
c. Administration of atropine
d. Administration of epinephrine
Give this one a try later!
Multiple pvc's coming from multiple locations (multifocal) is a real problem
and you should administer oxygen FIRST, so ANSWER is B. lidocaine will
help reduce irritability of heart and help with pvc's but would not be first
option, atropine is used for bradycardia and cardiac irregularities but not
pvc's, epinephrine is emergency drug not for pvc's but more for pulseless
ventricular tachycardia or ventricular fibrilation where heart is not
responding .
A patient in the emergency dept has frothy secretions, moist crackles, and tachypnea.
The patient has marked dyspnea and a history of heart disease. Which of the following
should the respiratory therapist recommend.
1.suction immediately
2.administer 100% oxygen
3.place in Fowlers position
4.administer furosemide
Give this one a try later!
, This is an emergency, they are having heart problems, dyspnea, frothy
secretions indicating severe pulmonary edema, etc. so 100% oxygen
immediately, having the patient in the Fowlers position (an upright position)
will help pull fluid down away from the lungs, furosemide is a lasix (loop
diuretic) which gets rid of excess fluid. You do NOT suction someone with
frothy secretions and heart problems, this just delays appropriate therapy.
So ANSWER is 2,3,4
Which of the following is a potential side effect of inhaled nitric oxide therapy?
A. Systemic hypotension
B. Formation of nitrous oxide
C. Oxygen toxicity
D. Methemoglobinemia
Give this one a try later!
Answer is D. Nitric oxide is for pulmonary hypertension. Nitric oxide can
alterate hemoglobin which is why D is the best answer.
What is the normal range for the mean pulmonary artery pressure in an adult
a. 2-6 mm Hg
b. 4-12 mmHg
c. 9-18 mmHg
d. 21-28 mmHg
Give this one a try later!
Mean pulmonary artery pressure in an adult should be in the teens
so best ANSWER is C
, What is the function of the one-way valve on a mouth-to-valve mask resuscitation
device?
A. Increase the delivered FIO2
B. Prevent the patient from exhaling back
C. Prevent the patient from breathing room air
D. Control the flow of gas to the patient
Give this one a try later!
A mouth-to-valve mask resuscitation device eliminates direct contact with
the patient as in mouth-to-mouth resuscitation. The one-way valve on this
device prevents the patient from exhaling back, so the ANSWER is B.
What total flow is delivered to a patient if the air entrainment mask is set at 35%
oxygen and the flowmeter is set at 6 L/min?
A. 20 - 25 L/min
B. 30 - 35 L/min
C. 40 - 45 L/min
D. 50 - 55 L/min
Give this one a try later!
Question 12 of 15 - Need I:E ratio of 35% X 6 L/min
Question 10 of 15 - A patient is receiving mechanical ventilation at the following
settings:
Mode: VC, SIMV
Mandatory rate: 12 /min
Total rate: 12 /min
FIO2: 0.50
VT: 700 mL
a. systolic + systolic + diastolic/3
b. diastolic + pulse pressure/3
c. systolic pressure - diastolic pressure
