ATI Fundamentals

Correct Answer: C

Rationale: A client who was vaccinated for pneumococcus and influenza 6 months ago would have a reduced risk of developing pneumonia compared to those who have not been vaccinated. Vaccination helps protect individuals from specific pathogens, thereby lowering the risk of infection. Clients with dysphagia, AIDS, or a closed head injury and receiving ventilation are at higher risk for pneumonia due to compromised immunity, respiratory function, or protective airway reflexes, respectively.

Correct Answer: B

Rationale: When assessing a client with a chest tube and drainage system, gentle constant bubbling in the suction control chamber is an expected finding. This indicates that the system is functioning properly. Continuous bubbling in the water seal chamber would suggest an air leak, the drainage system should be positioned upright at chest level to promote proper drainage, and exposed sutures without dressing would be an incorrect finding as they should be covered to prevent infection.

Correct Answer: C

Rationale: Patients who have experienced a left-hemispheric stroke may exhibit symptoms of agnosia, which is the inability to recognize familiar objects or people. This occurs due to damage to the right hemisphere of the brain, which is responsible for visual and spatial perception. Impulse control difficulty, poor judgment, and loss of depth perception are not typically associated with left-hemispheric strokes.

Correct Answer: B

Rationale: Pale skin is an early manifestation of hypoxemia due to decreased oxygenation of the blood. The skin may appear pale as the body redirects blood flow to vital organs in response to low oxygen levels. Confusion, bradycardia, and hypotension may occur as hypoxemia worsens, but pale skin is one of the initial signs that healthcare professionals should recognize when assessing a client experiencing respiratory distress.

Correct Answer: B

Rationale: A Venturi mask is the most appropriate choice for delivering a precise amount of oxygen to a client with dyspnea. Unlike other oxygen delivery devices, the Venturi mask allows for accurate oxygen concentration delivery by controlling the amount of air entrained. This feature is crucial in ensuring the client receives the prescribed oxygen concentration, especially in cases where precise oxygen delivery is required.
