Scenario:Mr. D is a 79-year-old male admitted to the hospital for management of congestive heart failure. He has a history of type 2 diabetes, mild cognitive impairment, and osteoarthritis. He wears bifocal glasses and reports occasional dizziness when standing. During his hospital stay, the nurse notes that Mr. D frequently gets out of bed without using the call light and was recently found trying to walk to the bathroom without assistance. His medications include metformin, furosemide, and a low-dose antipsychotic for sleep disturbances. He requires help with grooming and dressing. The nurse observes his footwear are hospital-issued socks with non-slip grips. What is the nurse’s most appropriate initial intervention to prevent a fall for Mr. D?

What is the primary goal of using the 30 second chair stand test? 

A 78-year-old patient reports dizziness when standing up quickly. What is the nurse’s first priority?

A non-inferiority study compared risankizumab (intervention) to secukinumab (standard of care) for at least 90% improvement in plaque psoriasis symptoms (i.e., achievement of the PASI90). An NI margin of 12% was used. Risankizumab was found to achieve PASI90 in 73.8% of patients and secukinumab in 65.6% of patients (difference of 8.2%; 95%CI 0.8 to 38.8%). Which of the following is the best interpretation of these results. Compared to secukinumab:

Determine the reactions at roller support A, fixed support B, and at joint C. If members BCD and AC are connected by a spring (EF) with a stretch of 7in and a spring constant k=30lb/in, and if the frame is subject to the loading condition shown, which include a 125lb・in concentrated moment, acting at the middle of the segment FB.

A truss is supported by a pin support at A and roller support at H (shown below). Determine the forces in members BC, FC, GH and CG and whether the members are in Tension or Compression.

An investigator conducts a study comparing lowopril (a new ACE-inhibitor) to lisinopril in patients with uncontrolled hypertension. The NI margin is set at 6 mmHg. Lowopril lowered blood pressure by 6.1 mmHg and lisinopril lowered by 7.8 mmHg. The difference in blood pressure lowering was 1.7 mmHg (95%CI 0.1 to 3.3). Describe the appropriate interpretation of the results in the context of the NI margin.
