In an outpatient orthopedic clinic, the physical therapist is treating a patient who is undergoing lung cancer treatment for deconditioning. On their fourth visit, the patient reports new left thigh pain and swelling. The area is warm to the touch. They deny any recent injury or trauma. Which of the following is the most appropriate screening tool for the differential diagnosis of this new complaint?

During a physical therapy session, a patient reports subjective dyspnea while ambulating on 2 LPM of oxygen via nasal cannula with SpO2 of 97%. The patient requests that the physical therapist increase the oxygen for exercise so they can “get enough air”. The physician’s order allows for “titration as needed to maintain adequate SpO2.” Which of the following is the most appropriate response?

A patient explains to the physical therapist that their metoprolol was increased at their last cardiology appointment. They have been reluctant to take it every day because they like to walk for exercise and they struggle to walk at the pace they are used to. Which of the following side effects is likely impacting their activity tolerance?

The United States Environmental Protection Agency advises children under 12 years and people who are pregnant or breastfeeding to limit their intake of certain fishes. In particular, fish such as sardines, tilapia, and trout that eat zooplankton, phytoplankton, or insect larvae etc. are safe to eat 2-3 times a week. In contrast albacore tuna, and halibut, which eat other fish should only be consumed once a week, and a top predator such as shark should not be consumed at all by these vulnerable individuals. These dietary recommendations are intended to limit the intake of mercury, which can negatively impact developing brains and nervous systems. In your own words, what is biomagnification? Using what you know about trophic levels and properties of toxins, write a paragraph explaining how biomagnification happens. Why is biomagnification a problem? Give at least one specific example of a negative consequence of biomagnification.

The beam has a rectangular cross section with D = 55 mm, d = 50 mm, r = 10 mm, and a thickness of 6 mm. If M = 23.8 N·m, determine the maximum normal stress at the section through the base of the fillets using Figures 14.24 and 25.

The tension member has a rectangular cross section with D = 65 mm, d = 50 mm, r = 7.5 mm, and a thickness of 3 mm. If P = 3.2 kN, determine the maximum normal stress at the section through the base of the fillets using Figure 14.16.

The notched bar is subjected to an axial tensile load of P = 13 kN. The major bar width is D = 116 mm, the minor bar width at the notches is d = 100 mm, and the radius of each notch is r = 2 mm. If the maximum tensile stress in the bar must not exceed 77 MPa, determine the minimum required bar thickness using Neuber’s nomograph (Table 14.3 and Figure 14.10).
