With Von Willebrand’s Correct answer- the only laboratory abnormality is increased
bleeding time (literally you prick the patient and see how long it takes them to stop

RSV is an RNA virus that enters the cell Correct answer- via a fusion protein (which is
the target of the prophylactic monoclonal antibody drug Palivizumab).*
RSV is an RNA virus Correct answer- causes RSV Bronchialitis
1 / 2
RSV is an RNA virus Correct answer- has a property of mediation of cell entry via fusion
protein
β2 adrenergic agonists’ effects on smooth muscle Correct answer- cause dilation of
bronchial passages, vasodilation in muscle and liver, relaxation of uterine muscle, and
release of insulin
β2 adrenergic agonists Correct answer- are primarily used to treat asthma and other
pulmonary disorders, such as COPD bilateral wheezing as a result of a bee sting
The purpose of Rhogam Correct answer- is to bind to and remove the RhD antigens so
that the mother does not form an immune response against the antigen in fetus’ blood.
Rhogham administration Correct answer- It’s given to at-risk Rh- moms at 28 weeks and
at deliver
Mom is group O and baby is RH Negative give Correct answer- give Rhogham
Metformin causes Correct answer- 1. Hepatic glucose out put to be decreased
- target tissue glucose uptake and utilization to be increased
Metformin(Glucophage) Correct answer- decreases hepatic glucose production,
decreases intestinal absorption of glucose, and improves insulin sensitivity by
increasing peripheral glucose uptake and utilization.*
colicky right flank pain that radiates to
the groin and hematuria.
Ultrasound examination of the kidneys shows right-sided hydronephrosis and a dilated
ureter.
Which of the following is most likely to be found on urinalysis? Correct answer- Uric acid
crystals
Neisseria gonorrhoeae gram stain of the
exudate Correct answer- shows numerous neutrophils, many that contain intracellular
gram-negative diplococci.
Neisseria gonorrhoeae Correct answer- is able to switch out different pilin genes, and
for this reason, prior infection does not confer long-lasting immunity.
Gonorrhea Correct answer- Gonorrhea can change its pilus, which is responsible for
adhesion to host cells and the main antigen to which the host mounts an immune
response.
Neisseria gonorrhoeae Correct answer- has the property of antigenic variation which
causes reinfection
