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: D

Rationale: In a right-hemispheric stroke, the expected findings include left-sided hemiplegia (Choice B), loss of depth perception (Choice C), and impulse control difficulty (Choice A). Aphasia (Choice D) is typically associated with left-hemispheric strokes. Therefore, aphasia is not an expected finding in a client who has experienced a right-hemispheric stroke.

Correct Answer: B

Rationale: Pressure support ventilation (PSV) is a mode that delivers a preset pressure when the client initiates a breath. This support helps the client to breathe spontaneously by reducing the work of breathing. The correct statement indicating an understanding of PSV is that it allows preset pressure to be delivered during spontaneous ventilation, as it assists the client's efforts without controlling the rate or volume of each breath.

Correct Answer: C

Rationale: Stripping the drainage tubing is an outdated practice and can cause complications. Encouraging the client to cough helps with lung expansion, checking for continuous bubbling ensures proper functioning of the chest tube system, and obtaining a chest x-ray helps to assess the position of the chest tube and re-expansion of the lung. Therefore, stripping the drainage tubing every 4 hours should not be included in the plan of care.

Correct Answer: D

Rationale: Following chest tube placement, an indwelling urinary catheter is not typically needed or relevant to the care provided. Chest tube placement is primarily concerned with managing pleural effusion or pneumothorax, and urinary catheterization is not directly related to this procedure. Oxygen, sterile water, and enclosed hemostat clamps are commonly used items in the care of a client with a chest tube in place, to ensure proper oxygenation, maintain drainage system integrity, and manage any bleeding that may occur. Therefore, the indwelling urinary catheter should not be available in the client's room following chest tube placement.
