CCT - Practice Test Questions with Verified Solutions 1. Which heart chamber functions to pump deoxygenated blood to the lungs? a. Right atrium b. Right ventricle c. Left atrium d. Left ventricle 1. B: The right ventricle pumps the deoxygenated blood it has received from the right atrium to the lungs. The right atrium pumps deoxygenated blood from the body to the right ventricle. The left atrium pumps oxygenated blood from the lungs to the left ventricle. The left ventricle pumps ...

To determine whether there is a delay in impulse conduction through the ventricles, the nurse will measure the duration of the patient's: A) p wave B) q wave C) pr interval D) qrs complex D) qrs complex (the qrs complex represents ventricular depolarization. The p wave represents the depolarization of the atria. The pr interval represents depolarization of the atria, av node, bundle of his, bundle branches, and the purkinje fibers. The q wave is the first negative deflection following the...

Conduction System of the Heart correct answers The SA (sinoatrial) node spontaneously generates impulses at a rate of 60-100bpm This stimulates the atria to contract and travel to the AV node The signal gets briefly held in the AV node and is then conducted through the bundle of His, Purkinje fibers and the ventricular epicardium If the SA node can't fire the AV junction will take over at a rate of 40-60bpm If both the SA and AV junction don't fire the ventricles generate an impuls...

Pulmonary artery - CORRECT ANSWER-One of two arteries that carry venous (oxygen poor) blood from heart to lungs What type of intubation is preferred with emesis with aspiration? - CORRECT ANSWER-ETT. LMA or combitube acceptable. What emergency would a cricothyrotomy typically be performed? - CORRECT ANSWER-Airway obstruction Atropine would be given in which emergency? - CORRECT ANSWER-Symptomatic bradycardia Adenosine would be given in which emergency? - CORRECT ANSWER-SVT Amiodarone would ...

Fisdap Cardiology ExamWhere are Beta 1 receptors found? Correct Answer: Heart and Kidneys Stimulation of Beta 1 receptors results in an increase of what? Correct Answer: Heart: Inotropy, Chronotropy, Dromotropy Kidneys: Renin-Angiotensin-Aldosterone System = Vasoconstriction = Increase blood pressure Which node is located at the junction of the superior vena cava and the right atrium, is typically supplied by the Right Coronary artery, and fires at a rate of 60-100 bpm. Correct Answ...

ACLS Exam Fall 2022 Complete Questions & Answers. When providing transcutaneous pacing, the appearance of wide QRS complexes and tall, broad T waves after each pacing spike confirms that mechanical capture has been achieved. 2 In a six-person high-performance resuscitation team, which tasks are responsibilities of the team members? Select all correct options that apply. Recording key data Sharing pertinent observations Ordering interventions Performing chest compressions Going to ...

Telemetry med surg exam 3 Sinus node The intrinsic pacemaker. Cell membrane "leakiness" causes spontaneous depolarization at a rate of 60-100 times a minute. AV node Acts like a resistor to slow the impulse allowing time for the atria to completely contract before initiating ventricular contraction. Back up pacemaker if SA fails, pacing at a rate of 40-60 times a minute. Bundle of his "Cable" that passes through the fibrous sheath separating atria from ventricles. Divides into th...

P wave - ANSWER Depolarization of the atria PR interval - ANSWER -Normal is 0.12 to 0.2 seconds - onset of atrial depolarization until onset of ventricular polarization QRS complex - ANSWER -Normal is 0.06 to 0.11 seconds -Ventricular depolarization -systole T wave - ANSWER -appears after QRS complex - Ventricular repolarization -Spiked T-wave occurs with hyperkalemia U wave - ANSWER - repolarization of the purkinje fibers - seen in patients with hypokalemia SA node - ANSWER...
