Correct Answer: C

Rationale: The correct answer is C because a lack of response to intradermal anergy testing suggests an inability to mount a normal delayed-type hypersensitivity response, indicating immunodeficiency. This could be due to conditions such as HIV, which impairs cell-mediated immunity. Choice A is incorrect because absence of reaction does not necessarily indicate lack of previous exposure to antigens. Choice B is incorrect as the absence of response doesn't confirm the presence of antibodies. Choice D is incorrect because anergy testing is not used to assess allergy, but rather to evaluate cell-mediated immunity.

Correct Answer: B

Rationale: The correct answer is B because involving the client and family in developing outcomes promotes patient-centered care and increases the likelihood of achieving successful outcomes. This approach fosters collaboration, shared decision-making, and empowers the client and family in their own care. It also helps to ensure that the outcomes align with the client's values, preferences, and goals. Choices A, C, and D are incorrect because focusing solely on nursing goals without considering the client's perspective may lead to a lack of engagement and poor outcomes. Discouraging input from other healthcare providers limits the interdisciplinary approach to care, and focusing on why the nurse believes the outcome is important neglects the client's role in the decision-making process.

Correct Answer: A

Rationale: The correct answer is A: 2 L/min. In emphysema, there is impaired gas exchange due to damaged lung tissue, resulting in decreased oxygen levels. Administering too high a flow rate can lead to oxygen toxicity. The standard oxygen therapy for emphysema is 1-2 L/min to maintain oxygen saturation without causing harm. Higher flow rates like 10 L/min (B) and 6 L/min (C) are excessive and can lead to oxygen toxicity. 95 L/min (D) is dangerously high and not suitable for oxygen therapy in emphysema. Therefore, A is the correct choice for safe and effective oxygen administration in emphysema.

Correct Answer: A

Rationale: Correct Answer: A Rationale: 1. Lymphangitis is an inflammation of lymphatic vessels. 2. If the affected area appears to enlarge, it indicates possible worsening or spreading of the infection. 3. Nurse should notify the physician for further evaluation and treatment. 4. Red streaks extending up the arm or leg (B) are common signs of lymphangitis, not necessarily requiring immediate physician notification. 5. Additional lymph nodes becoming (C) is a normal response to infection and may not warrant immediate physician notification. 6. Liver and spleen enlargement (D) are not directly related to lymphangitis and do not require immediate notification.

Correct Answer: D

Rationale: The correct answer is D: Reassess the client's condition. When an expected outcome is not achieved, the nurse must reassess the client's condition to identify the reasons for the lack of success. This step allows the nurse to gather more information, adjust the plan of care if necessary, and determine the most suitable course of action to help the client achieve the desired outcome. Choice A: Terminating the plan of care is premature without reassessing the client's condition and identifying potential barriers to success. Choice B: Modifying the plan of care may be necessary after reassessment but should not be the first step. Choice C: Reassigning care to another nurse does not address the underlying issues affecting the client's response to the intervention.
