Correct Answer: C

Rationale: Pursed-lip breathing is a common manifestation in clients with emphysema. It helps to increase the duration of exhalation and reduce air trapping, aiding in the management of the condition. Decreased chest expansion and bradypnea are not typically associated with emphysema. While cyanosis can occur in severe cases, pursed-lip breathing is a more specific and commonly observed sign of emphysema.

Correct Answer: C

Rationale: When providing tracheostomy care, it is important to ensure the client's safety and prevent pressure ulcers. When securing ties that require knotting, the knot should be placed at the side of the client's neck, not at the back. Tying a square knot at the back of the neck could lead to discomfort, pressure ulcers, or accidental tightening. Holding the device securely, suctioning the client as needed, and using appropriate cleansing solutions are all essential components of tracheostomy care.

Correct Answer: C

Rationale: Suprasternal retraction during inhalation suggests the client is using accessory muscles due to difficulty in moving air into the respiratory passages caused by airway narrowing. The presence of bilateral wheezing and decreased pulse oxygen saturation further support airway narrowing. In this situation, immediate intervention is necessary to improve oxygenation. Administering oxygen to maintain saturations above 94% is crucial to support oxygenation. While administering a rescue inhaler may be warranted, the priority in this scenario is ensuring adequate oxygenation to address the respiratory distress.

Correct Answer: A

Rationale: The priority action for a client with an oxygen saturation of 88% on room air is to initiate oxygen therapy to improve oxygen saturation levels. Oxygen therapy is crucial to address hypoxemia promptly. Placing the client in a high-Fowler's position can also aid in oxygenation, but administering oxygen takes precedence. While notifying the healthcare provider is important, it is a secondary action after ensuring the client's immediate need for oxygen is met. Documenting the finding in the client's medical record is necessary for continuity of care but is not the primary intervention when addressing hypoxemia.

Correct Answer: A

Rationale: The correct answer is African American churches. African Americans in the United States have one of the highest rates of hypertension globally. By providing services at African American churches, the nurse can effectively reach this priority population. While hypertension education and screening are essential for all groups, African Americans are the priority population for this intervention due to their disproportionately high rates of hypertension.
