A school-age child has a fractured wrist with a Salter-Harris Type II fracture on x-ray. What is true about this type of fracture?

An adolescent who has asthma and severe perennial allergies has poor asthma control in spite of appropriate use of a short-acting beta2-agonist (SABA) and a daily high-dose inhaled corticosteroid. What will the primary care pediatric nurse practitioner do next to manage this child’s asthma?

What physical findings is most indicative of a Kawaski viral infection?

Rotational kinematics with constant angular acceleration: In the figure, point P is at rest when it is on the x-axis. The time t, when P returns to the original position on the x-axis, is closest to

An adolescent who has exercise-induced asthma (EIA) is on the high school track team and has recently begun to practice daily during the school week. The adolescent uses 2 puffs of albuterol via a metered-dose inhaler 20 minutes before exercise but reports decreased effectiveness since beginning daily practice. What will the primary care pediatric nurse practitioner do?

For the Cu-Ni phase diagram below, what fraction of the system is liquid for 50 wt% Ni at 1300C

Satellites: A satellite in a circular orbit of radius R around planet X has an orbital period T. If Planet X had one-fourth as much mass, the orbital period of this satellite in an orbit of the same radius would be

Refer to the phase diagram and figures below and identify the microstructure that corresponds to 50wt% Sn- 50wt%Pb at 150°C

The International Space Station is orbiting at an altitude of about 370 km above the earth’s surface. The mass of the earth is 5.97 × 1024 kg, the radius of the earth is 6.38 × 106 m, and G = 6.67 × 10-11 N ∙ m2/kg2. Assume the orbit is circular. (a) What is the period of the International Space Station’s orbit? (b) What is the speed of the International Space Station in its orbit? (c) The ISS has a mass of approximately 4.45 × 105 kg. Calculate the total mechanical energy of the ISS in its orbit.

Consider a metal single crystal oriented such that the normal to the slip plane and the slip direction are at angles of 60° and 35°, respectively, with the tensile axis. If the critical resolved shear stress is 7 MPa, will an applied stress of 13 MPa cause the single crystal to yield? If not, what stress will be necessary?
