ATI Fundamentals Proctored Exam 2023 Quizlet

Correct Answer: B

Rationale: Acute illnesses are characterized by the sudden onset of severe symptoms that typically last for a short duration. These conditions usually resolve within a defined period, unlike chronic illnesses that persist over a longer time frame. Pain and syndrome are not specific types of illnesses but rather symptoms or clinical manifestations that can occur in various health conditions.

Correct Answer: A

Rationale: The left atrium receives oxygenated blood from the lungs via the pulmonary veins. This oxygen-rich blood is then pumped into the left ventricle before being circulated throughout the body. The right atrium, on the other hand, receives deoxygenated blood from the body via the vena cava.

Correct Answer: A

Rationale: The Snellen chart is used to test visual acuity, which assesses the function of the optic nerve responsible for vision. The other options are not related to vision; olfactory relates to the sense of smell, oculomotor controls eye movement, and trochlear controls certain eye muscles.

Correct Answer: A

Rationale: The correct answer is the lens. The lens is a transparent structure in the eye that helps to focus light onto the retina, which is essential for clear vision. The cornea and sclera are also important parts of the eye, but the lens specifically plays a crucial role in focusing light onto the retina.

Correct Answer: B

Rationale: Before rigor mortis occurs, it is essential to place a pillow under the body's head and shoulders to maintain proper positioning. This helps prevent postmortem changes and ensures a more dignified appearance. Providing a complete bath and dressing change, removing clothing, or wrapping the body in a shroud are tasks typically done after rigor mortis sets in or later in the postmortem care process. Allowing the body to relax normally does not address the need for proper positioning before rigor mortis occurs.
