Correct Answer: A

Rationale: The correct answer is A: Administer oxygen and provide breathing exercises. These interventions are essential in managing COPD as they help improve lung function and oxygenation. Choice B is incorrect as suctioning airway secretions and encouraging coughing are not typically indicated for COPD patients. Choice C is incorrect as while administering bronchodilators is common in COPD treatment, monitoring oxygen saturation alone is not a comprehensive intervention. Choice D is incorrect as restricting fluids is not a standard intervention for COPD, and encouraging mobility, although beneficial, is not as directly related to managing COPD symptoms as administering oxygen and providing breathing exercises.

Correct Answer: D

Rationale: Restlessness and agitation in clients with dementia could indicate a worsening condition and should be prioritized. While wandering at night and urinary incontinence are common issues in dementia patients, restlessness and agitation can signal acute distress or an unmet need, requiring immediate attention. Monitoring serum albumin levels is important for overall health but would not be the priority when assessing a client with dementia.

Correct Answer: B

Rationale: Ataxia, which refers to difficulty with coordination, is a common symptom seen in individuals with multiple sclerosis. Nystagmus, the involuntary eye movement, can also occur in multiple sclerosis but is not as common as ataxia. Fatigue is a common symptom in multiple sclerosis, but ataxia is more specific. Fever is not a typical finding associated with multiple sclerosis.

Correct Answer: D

Rationale: Option D is the most appropriate response as it acknowledges the client's expressed uncertainty about the surgery. By acknowledging the client's feelings, the nurse validates their concerns and opens the door for further discussion. This approach can help build trust and rapport with the client. Option A focuses more on seeking justification for the client's belief rather than addressing the underlying emotion. Option B, while acknowledging doubt, does not directly address the client's feelings. Option C, although well-intentioned, dismisses the client's concerns without exploring them further.

Correct Answer: A

Rationale: The correct nursing intervention for a patient with a pressure ulcer is to clean the wound and apply a hydrocolloid dressing. This promotes healing by creating a moist environment conducive to the wound healing process. Choice B is incorrect because while nutrition is important for wound healing, a high-protein diet alone is not a specific intervention for a pressure ulcer. Choice C is incorrect as antibiotics are only used if there is an infection present. Choice D is also incorrect as a low-sodium diet and monitoring for fluid retention are more related to conditions like heart failure or kidney disease, not specifically pressure ulcer care.
