Correct Answer: C

Rationale: The most appropriate action for the nurse is to allow the client the time needed to dress. Patients with Parkinson's disease may experience difficulties with activities of daily living due to their condition. Allowing the client sufficient time to dress promotes independence and dignity, which are essential aspects of patient-centered care. Asking family members to dress the client may undermine the client's autonomy and self-esteem. Encouraging the client to dress more quickly may lead to frustration and feelings of inadequacy. Demonstrating methods on how to dress more quickly may not address the underlying challenges the client faces and could be perceived as insensitive or dismissive of the client's needs.

Correct Answer: B

Rationale: The client's inability to effectively clear the airway due to pain and sputum production hinders the cough mechanism, making 'Ineffective airway clearance' the most appropriate nursing diagnosis. Although impaired gas exchange may occur due to the pneumonia, the immediate issue is the inability to clear the airway. 'Ineffective breathing pattern' does not address the specific issue of airway clearance. 'Anxiety' is not the priority when the focus should be on the physical complications of pneumonia.

Correct Answer: A

Rationale: The correct answer is A. Chest indrawing may not always be present and can vary with the child's activity level, so it should not be expected to be present at all times. Choice B is correct because the lower chest wall should not go in when the child breathes in. Choice C is correct as the lower chest should go in when the child breathes in, indicating chest indrawing. Choice D is correct as a calm child makes it easier to assess chest indrawing, but the absence of chest indrawing does not mean the child is not calm.

Correct Answer: B

Rationale: The correct answer is B: botulism toxin. Botulism toxin is associated with symmetric, descending flaccid paralysis, blurred vision, double vision, and dry mouth, which are consistent with the client's presentation. Ricin (Choice A) typically presents with gastrointestinal symptoms. Sulfur mustard (Choice C) is a blistering agent causing skin, eye, and respiratory issues. Yersinia pestis (Choice D) is associated with the bubonic plague, presenting with fever, malaise, and buboes.

Correct Answer: A

Rationale: The correct answer is A: Primary prevention. Administering a booster dose of DTaP vaccine to an infant is an example of primary prevention. Primary prevention aims to prevent disease or injury before it occurs by preventing exposure to risk factors. Tertiary prevention focuses on reducing the impact of a disease or injury that has already occurred, while secondary prevention involves early detection and treatment to prevent the progression of disease. Choice B, tertiary prevention, is incorrect as it deals with managing the consequences of a disease rather than preventing it. Choice C, secondary prevention, is also incorrect as it focuses on early detection and treatment rather than vaccination to prevent the disease. Choice D, primary nursing, is unrelated to the level of prevention being implemented in this scenario.
