The spherical face shield of an astronaut’s helmet is made from polycarbonate with a yield strength of 101 MPa. The shield has an outside diameter of 350 mm and a thickness of 4.1 mm. If the shield is successfully pressure tested to 835 kPa on Earth, determine the factor of safety with respect to yielding.

An upward load is applied to a circular rod that has a diameter of 10.55 mm. The rod is connected to the ground using a pin that has a diameter of 9.57 mm. If the normal stress in the rod is limited to 295 MPa and the average shear stress in the pin is limited to 135 MPa, determine the maximum load that can be applied to this connection.

A patient in the Surgical Trauma Intensive Care Unit (STICU) develops a sudden onset of narrow-complex tachycardia with a rate of 220 beats per minute. The patient’s blood pressure is 124/64 and the pulse oximetry is 99%. The patient has vascular access in the right arm and has not been given any vasoactive drugs. A 12-lead ECG confirms supraventricular tachycardia (SVT) with no evidence of cardiac ischemia. The heart rate has not responded to a modified valsalva maneuver. What is your next action?

A client converts from normal sinus rhythm at 80 bpm to atrial fibrillation with a ventricular response at 166 bpm. Blood pressure is 162/74 mm Hg. Respiratory rate is 20 breaths per minute with normal chest expansion and clear lungs bilaterally. IV heparin and Diltiazem are given. The nurse caring for the client understands that the main goal of treatment is what?
