Jill


"Thank you for the exceptional HESI tests! I failed the HESI several times before I discovered your website. I took all your practice tests and this time I passed!!!"

Sharon


"I just took my Hesi exit PN today and got a Hesi score of 1205 and a conversion score of 99.99%. Thanks for the help. Doing all those tests helped so much. Not because I saw the same questions but because I learned so much from the answer reasoning section. Hope to fly through my boards in a couple weeks. Thanks again, it was money well spent."

Welsh


"I recently had to test out of my school with an 850 on the Hesi PN, so I punched the exams from you guys about 5 to 7 exams and passed the exit HesiPn with an 988! First time around! Then I punched the NclexPN exam tests from you guys and I passed my nclex first time around! These test really helped me to study well, I am a slow learner and still yet, was able to pass! I highly recommend you purchase the tests! It will totally be worth your money! Thank you so much,"

DIANA


"I want to thank you... the tests are really helpful. I took it three times and after using your exams I finally passed it. The tests helped me specially on math section, which I got 90. "

Juliet M.


"I can't believe this website has no high following status. I bought 40 practice questions, and I did 20 practice questions and took my Hesi exit. I scored 1070. I completed all 40 practice exams and passed my boards for the first time. Exam Edge introduced me to a bunch of topics and boosted my confidence. They're rationales are so brief and straight to the point. They're not overwhelming. Thank you, Exam Edge team"

HESI EMT-Basic Exit - Test Reviews Sample Questions

Breathing is mainly forced or driven by the

Correct Answer:
diaphragm.


breathing, a critical life-sustaining process, is primarily driven by the diaphragm. the diaphragm is a large, dome-shaped muscle located at the base of the lungs and the top of the abdomen. when you inhale, the diaphragm contracts and flattens out, moving downward toward the abdomen. this increases the space in your chest cavity, allowing your lungs to expand. as the lungs expand, air is drawn in through the nose or mouth, travels down the trachea, and fills the lungs.

the role of the diaphragm in breathing is crucial because it creates a pressure difference that facilitates the inflow of air. when the diaphragm contracts, it reduces the pressure inside the thoracic cavity relative to the outside atmosphere, effectively pulling air into the lungs. conversely, when you exhale, the diaphragm relaxes and moves upward, reverting to its dome shape, which decreases the space in the chest cavity and pushes air out of the lungs.

while the diaphragm is the primary muscle responsible for breathing, other parts of the respiratory system also play supportive roles. the intercostal muscles between the ribs assist by elevating the ribs and expanding the chest cavity further. additionally, structures like the trachea, alveoli, and larynx are involved in the air passage and gas exchange but do not drive the breathing process.

therefore, understanding the function and mechanics of the diaphragm is essential in appreciating how breathing occurs. its unique position and muscle structure make it indispensable for the inhalation and exhalation processes that sustain life.

Where is the coronary sinus located?

Correct Answer:
on the posterior side of the heart.


the coronary sinus is a large vein located on the posterior aspect of the heart and plays a crucial role in the heart's circulatory system. its primary function is to collect deoxygenated blood from the heart muscle (myocardium) and deliver it back to the right atrium, which is one of the four chambers of the heart. this is a key component of the cardiac venous system, which is responsible for facilitating the removal of carbon dioxide and waste products from the myocardial cells.

anatomically, the coronary sinus is situated in the atrioventricular groove that separates the left atrium and the left ventricle from the right atrium and the right ventricle. this position allows it to effectively gather blood from smaller veins covering the myocardium—specifically, the great cardiac vein, the middle cardiac vein, and the small cardiac vein among others—before it empties into the right atrium.

the significance of the coronary sinus extends beyond its anatomical location and function. in some medical procedures, such as during the administration of drugs or the implantation of pacemaker leads, the coronary sinus can serve as an important access pathway. given its size and strategic location, it provides a viable route for interventions that require access to the heart, particularly the left side of the heart.

understanding the location and function of the coronary sinus is crucial for healthcare professionals, especially those involved in cardiology and cardiovascular surgeries. its role in the drainage of the heart's venous blood makes it a significant structure in the overall cardiovascular system.
