Correct Answer: A

Rationale: The correct answer is A: Malignant. A malignant tumor spreading to surrounding tissues indicates invasive growth, characteristic of malignancy. It is aggressive and can invade nearby structures. Non-malignant tumors are localized and do not invade surrounding tissues. Benign tumors are non-invasive and do not spread to other parts of the body. Choice D is incorrect because a tumor spreading to surrounding tissues is indicative of malignancy, not benignity.

Correct Answer: B

Rationale: The correct answer is B: Counseling about respite care options. This intervention is most appropriate as it addresses the issue of role strain by providing the family member with support and options for temporary relief from caregiving responsibilities. Respite care allows the family member to take a break and recharge, reducing stress and preventing burnout. A: Assisting with activities of daily living is important but may not directly address the underlying issue of role strain. C: Teaching range-of-motion exercises is beneficial for physical well-being but does not directly address the emotional and psychological impact of role strain. D: Consulting with a social worker may be helpful for additional support but may not provide immediate relief or practical solutions for the family member's role strain.

Correct Answer: B

Rationale: The correct answer is B: Ineffective airway clearance related to obstruction by a tumor or secretions. This is the highest priority because compromised airway clearance can lead to life-threatening complications such as respiratory distress or hypoxia. Ensuring effective airway clearance is crucial in preventing respiratory compromise and maintaining oxygenation. Choices A, C, and D are not the highest priority because they do not directly address the immediate risk to the client's physiological well-being. Treating disturbed body image, anxiety, or imbalanced nutrition are important but can be addressed after ensuring the client's airway is clear and they are able to breathe effectively.

Correct Answer: A

Rationale: The correct answer is A: Confusion or delirium can be a defense against further stress. This is because providing new information slowly and in small amounts can help prevent overwhelming Mr. Reyes, who is already confused. This approach allows him to process and understand the information more effectively without adding to his stress levels. Choices B, C, and D are incorrect: B: Destruction of brain cells has occurred, interrupting mental activity - This is not the most appropriate explanation as it assumes irreversible damage to the brain, which is not mentioned in the question. C: Teaching based on information progressing from the simple to the complex - While this may be a valid teaching strategy in general, it does not address Mr. Reyes' specific state of confusion and the need to reduce stress. D: A minimum of information should be given, since he is unaware of surrounding - This choice does not address the underlying reason for providing information slowly, which is to manage stress and confusion, rather than solely focusing on the

Correct Answer: C

Rationale: The correct answer is C: IgM. During an acute infection, the body's initial response is rapid and non-specific, leading to the production of IgM antibodies first. IgM is the first immunoglobulin class produced in response to a new antigen, providing immediate protection. IgG is produced later in the immune response and is responsible for long-term immunity. IgE is involved in allergic reactions and parasitic infections, not typically the first response to infection. IgD is primarily found on the surface of B cells and its function is not well understood in the context of acute infections.
