The behavioral change model that assumes that a person takes health action to avoid negative consequences, believing the action will prevent a negative outcome is:

An adult patient is being evaluated for asthma severity. Pulmonary function testing shows an FEV₁ of 78% of predicted. The patient reports nighttime awakenings about once per week, uses a short-acting β₂-agonist once daily, and has minimal limitation of normal activity. There have been no frequent exacerbations requiring oral corticosteroids. How would this patient’s asthma be classified?

A patient presents with well-demarcated, flat areas of depigmentation on the dorsum of the hand as shown in the image. The lesions are larger than 1 cm, non-scaly, and non-palpable. How should these skin lesions be classified?           

Miss Pink presents with a 1-day history of cough, which she notices only at night. She denies fever, shortness of breath, chest pain, or sputum production.

Ture or False: A quantity of radioactive material is measured in units of Gy in the traditional unit system.

True or False:  If emitted from a radioisotope deposited in the body, alpha particles cannot be absorbed in epithelial tissue and therefore are not damaging to that tissue.

Which of the following are types of ionizing radiation that produce virtually the same biologic effect for equal absorbed doses in body tissue?  (In other words, they have the same quality factor).

Which of the following interactions of radiation and matter is responsible for most of the scattered radiation produced during radiologic procedures?

During the process of photoelectric absorption, which of the following terms refers to the radiation that occurs when an electron drops down from an outer orbit to fill a vacancy in an inner orbit of the parent atom (what does it give off in this process)?
