Preeclampsia is a common problem during pregnancy. The condition — sometimes referred to as pregnancy-induced hypertension — is defined by high blood pressure and excess protein in the urine after 20 weeks of pregnancy. Often, preeclampsia causes only modest increases in blood pressure. Left untreated, however, preeclampsia can lead to serious — even fatal — [...]
Placenta previa is the development of placenta in the lower uterine segment, partially or completely covering the internal cervical os. The cause is unknown, but a possible theory states that the embryo will implant in the lower uterine segment if the deciduas in the uterine fundus is not favorable. Complications are immediate hemorrhage, shock, and [...]
Oxygenated blood enters the umbilical vein from the placenta
Enters ductus venosus
Passes through inferior venacava
Enters the right atrium
Enters the foramen ovale
Goes to the left atrium
Passes through left ventricle
Flows to ascending aorta to supply nourishment to the brain and upper extremeties
Enters superior vena cava
Goes to right atrium
Enters [...]

Nurse Valerie examines the neonate’s hands and palms. Which of the following findings requires further assessment?
a) Many crease across the palm.
b) Absence of creases on the palm.
c) A single crease on the palm.
d) Two [...]
Gout is a disorder of purine metabolism characterized by elevated uric acid levels with deposition of urate crystals in joints and other tissues. High uric acid levels result from decreased excretion of uric acid ( 90% of cases) due to a wide variety of causes. The disorder may progress from an asymptomatic stage through [...]
Ovum
The ovum is the female sex cell.
It is regularly released by the ovary through the process of ovulation.
It has two layers of protective covering, the outer layer is the corona radiata and the inner layer is the zona pellucida.
The egg cell has a lifespan of 24 hours, thus, it can only be fertilized within this [...]
The easiest way to improve your car’s performance and horsepower is to use a supercharger. Due to the increasing prices of oil and gasolines, adding a supercharger to your car and truck will definitely increase it’s mileage and efficiency. Forcing air to the engine gives additional boost of power and torque, that’s how supercharger for [...]
Bactrim, Co-Trimoxazole, Septra
Action:
Fixed combination of sulfamethoxazole (SMZ), an intermediate acting antiinfective sulfonamide, and trimethoprim (TMP), a synthetic antiinfective. Both components of the combination are synthetic folate antagonist antiinfectives. Mechanism of action is principally enzyme inhibition, which prevents bacterial synthesis of essential nucleic acids and proteins.
Classifications:
antiinfective; urinary tract agent; sulfonamide
Indication:
Pneumocystis carinii pneumonitis, Shigellosis enteritis, and [...]
Cozaar
Action:
Angiotensin II receptor (type AT1) antagonist acts as a potent vasoconstrictor and primary vasoactive hormone of the renin–angiotensin–aldosterone system.
Classifications:
cardiovascular agent; angiotensin ii receptor antagonist; antihypertensive
Indication:
Hypertension

Capoten
Action:
Lowers blood pressure by specific inhibition of the angiotensin-converting enzyme (ACE). This interrupts conversion sequences initiated by renin that lead to formation of angiotensin II, a potent endogenous vasoconstrictor. ACE inhibition alters hemodynamics without compensatory reflex tachycardia or changes in cardiac output (except in patients with CHF). Peripheral vascular resistance is lowered by vasodilation.
