Loop Diuretics - 🧠ANSWER ✔✔Prefix "emide" Furosemide.
Mechanism of action: Block water reabsorption in the loop of Henle of the
nephron. Increases urine output.
AE: decreased K+, decreased BP, Ototoxicity, nephrotoxicity.
Contradictions: auditory, renal impartments
During diastole, which part of the heart is filling with blood? - 🧠ANSWER
✔✔Both ventricles. Systole reflects the perfusing pressure of the
cardiovascular system where the ventricles eject blood from the heart.
Once complete, a resting period—diastole—follows, where blood must refill
the ventricles directly from the collection that occurred in the atria.
Oxygenated blood flows through which vessel? - 🧠ANSWER
✔✔Pulmonary vein. The superior vena cava carries all the deoxygenated

,blood from peripheral circulation back to the heart where it enters the right
atrium to be pumped into the right ventricle. The right ventricle pumps to
the lungs for oxygenation via the pulmonary artery. After pulmonary
circulation, the oxygenated blood is carried back to the heart via the
pulmonary vein.
What effect does atherosclerosis have on the development of an
aneurysm? - 🧠ANSWER ✔✔Erodes the vessel wall .Atherosclerosis, also
known as the process of "hardening of the arteries" and secondary to
plaque formation, weakens the flexibility of a blood vessel wall. Without
vascular compliance, the vessel wall becomes more rigid and susceptible
to rupture (i.e., an aneurysm).
Which complex (wave) represents the sum of all ventricular muscle cell
depolarizations? - 🧠ANSWER ✔✔The QRS wave of an electrocardiogram
(ECG or EKG) represents the largest spike in electrical activity of the heart,
as ventricular muscle cells perform the highest burden of work to pump
blood volume out of the heart in that instance.
Which factor is responsible for the hypertrophy of the myocardium
associated with hypertension? - 🧠ANSWER ✔✔Angiotensin II leads to
myocardial hypertrophy, poor myocardial compliance, and ventricular

,dilation through stimulating increased cardiac preload and afterload and
direct toxicity to myocardial cells. It causes sarcomere death, abnormal
collagen matrices, and interstitial fibrosis
Most cardiovascular developments occur between which weeks of
gestation? - 🧠ANSWER ✔✔During weeks four to seven, the primitive heart
tube progresses through numerous stages of development leading to a
developed heart with distinct atria, ventricles, and cardiac vessels.
Which compensatory mechanism is spontaneously used by children
diagnosed with tetralogy of Fallot (TOF) to relieve hypoxic spells? -
🧠ANSWER ✔✔Spontaneous squatting helps relieve hypercyanotic events
in older children through increasing systemic vascular resistance,
decreasing venous blood return. This provides a larger amount of
oxygenated blood for the body and leads to the temporary reversal of blood
through the ventricular septal defect (VSD), which results in increased
pulmonary flow. Squatting is rarely seen clinically because most TOF
defects are diagnosed and surgically repaired in infancy
Which condition is consistent with the cardiac defect of transposition of the
great vessels? - 🧠ANSWER ✔✔The aorta arises from the right ventricle. In
transposition of the great vessels, opposite of a normal heart, the aorta

, arises from the right ventricle, and the pulmonary artery arises from the left
ventricle.
A 26-year-old female presents to urgent care with complaints of extreme
fatigue, muscle aches, abdominal pain, numbness and tingling in her
extremities, and bloating. She explains that she has been experiencing
gastrointestinal upset after meals and has not had a bowel movement for
the past four days. She reports using over-the-counter, anti-diarrheal
products last week to combat diarrhea. She denies having any chronic
diseases. The assessment findings include a blood pressure of 108/71 mm
Hg, pulse of 82 beats per minute, and respirations of 20 breaths per
minute. The abdomen is distended and firm. Bowel sounds are present in
all four quadrants. The patient has a steady gait, though verbally complains
of feeling weak and off balance upon ambulation. Following antibody
testing, Celiac disease is suspected. Which follow-up tissue test, the gold
standard for this suspected diagnosis, should be ordered? - 🧠ANSWER
✔✔Endoscopy with small intestine biopsy
A 44-year-old woman has recently been diagnosed with advanced
metastatic non-small-cell lung cancer. Genetic testing is ordered to
determine if the patient's tumor has any genomic alterations and to guide
