Correct Answer: B

Rationale: Maintaining optimal function within the client's limitations is the most realistic and appropriate nursing goal when caring for an 80-year-old client with Parkinson's disease. This goal focuses on maximizing the client's abilities and quality of life while acknowledging the impact of the disease. Option A is less realistic as returning to usual activities may not always be achievable in the case of Parkinson's disease. Option C is not appropriate as it does not address the client's current condition and care needs. Option D is less realistic as Parkinson's disease is progressive, and delaying its progression may not be entirely feasible.

Correct Answer: B

Rationale: The first nursing action when caring for a client with a wound infection is to perform a wound culture before applying antibiotics. This step is crucial to identify the specific infecting organism and determine the most effective antibiotic therapy. Choices A, C, and D are incorrect because changing the dressing, cleansing the wound, or applying a wet-to-dry dressing should only be done after obtaining the culture results and starting appropriate antibiotic treatment.

Correct Answer: A

Rationale: The correct answer is A. A neurological assessment includes evaluating the level of consciousness and motor function as they are key components in assessing neurological function. Choices B, C, and D are incorrect as headache, nausea, reflexes, pupil size, tremors, and confusion may be part of a neurological assessment but are not the key components that are fundamental for a comprehensive assessment.

Correct Answer: B

Rationale: The correct answer is B because the client should press the button when feeling fetal movement to track the baby's activity. Choice A is incorrect because the client should press the button during movements. Choice C is incorrect as the button should be pressed during fetal movements, not contractions. Choice D is irrelevant to the instructions for the nonstress test.

Correct Answer: B

Rationale: The correct answer is to suction the tracheostomy. When a client with a tracheostomy is experiencing respiratory distress, the priority intervention is to clear the airway by suctioning the tracheostomy to remove secretions that may be obstructing the air passage. Administering a bronchodilator (Choice A) may be considered if bronchospasm is present, but the immediate focus should be on clearing the airway. Notifying the physician (Choice C) is important but should not delay the immediate intervention of suctioning. Increasing the oxygen flow rate (Choice D) may provide temporary relief, but addressing the root cause of the distress by suctioning is the priority.
