Correct Answer: D

Rationale: The correct answer is D. Clients with chronic obstructive pulmonary disease have difficulty exhaling fully due to the weak alveolar walls from the disease process. Pursed-lip breathing helps prevent alveolar collapse by maintaining positive pressure in the airways during exhalation. This is the major reason for using pursed-lip breathing in individuals with chronic obstructive lung disease. Choices A, B, and C are incorrect because they do not directly address the main purpose of pursed-lip breathing, which is to prevent alveolar collapse and improve exhalation in these patients.

Correct Answer: D

Rationale: The correct answer is that you cannot give her anything to eat or drink. 'NPO' is the standard abbreviation for 'nothing by mouth,' indicating that the patient should not consume any food or liquids. It is crucial to adhere to this restriction to prevent any potential harm or complications in the patient's condition. Choices A, B, and C are incorrect because 'NPO' clearly specifies that the patient should not have anything to eat or drink, including milk and crackers. Providing these items could lead to adverse effects, so it is essential to follow the 'NPO' directive strictly.

Correct Answer: C

Rationale: Raising the bed to the level of the nurse's waist while assisting a client with shampooing in bed is done to reduce strain on the nurse's back. This adjustment ensures that the nurse can work comfortably without excessive bending or stooping, thus preventing back injuries. Choices A, B, and D are incorrect. While preventing shampoo from getting into the client's eyes, allowing excess water to run off the bed, and preventing hair tangles are important considerations, the primary rationale for raising the bed is to prioritize the nurse's ergonomic safety and prevent musculoskeletal strain.

Correct Answer: C

Rationale: Emotional abuse involves behaviors that harm an individual's self-worth and emotional well-being. Threatening someone instills fear and causes psychological distress, making it a clear example of emotional abuse. Choices A, C, and D involve physical abuse, neglect, and neglect of care, respectively, rather than emotional abuse. A slap to the person's hand constitutes physical abuse, ignoring and isolating a person is neglectful behavior, and leaving a patient soiled for hours falls under neglect of care.

Correct Answer: B

Rationale: The correct answer is 'battery.' Battery occurs when there is unwanted physical contact or force applied to a person without their consent. In this scenario, force-feeding the patient against their will constitutes battery as the nurse is physically interfering with the patient's body without permission. Assault involves the threat of physical harm, which is not present in the situation described. Physical neglect refers to the failure to provide basic care needs, which is not the case here. Emotional neglect involves the failure to address emotional needs, which is also not applicable in this context.
