Which of the following lymphoid tissues has both hematopoietic and immune functions and acts as an emergency reservoir of blood and filters the blood as well?

Correct Answer: C

Rationale: The correct answer is C) Spleen. The spleen is a vital lymphoid tissue that serves both hematopoietic and immune functions. It acts as an emergency reservoir of blood, storing red blood cells and platelets, and can release them into circulation when needed. Additionally, the spleen filters the blood by removing old or damaged red blood cells, pathogens, and cellular debris. Option A) Tonsils and adenoids are important in the immune response against inhaled and ingested pathogens, but they do not have hematopoietic functions or act as a blood reservoir. Option B) Thymus gland is crucial for T-cell maturation but does not have hematopoietic functions or filter the blood. Option D) Lymph nodes play a key role in filtering lymph and trapping pathogens, but they do not have hematopoietic functions or act as a blood reservoir like the spleen. Understanding the functions of different lymphoid tissues is essential in pharmacology as it influences drug actions, especially those targeting the immune system. Knowing the unique roles of each tissue helps pharmacology students comprehend how drugs may impact specific immune responses based on their target organ or tissue.

Correct Answer: C

Rationale: In this scenario, the correct answer is C) Viatical settlement. A viatical settlement involves a terminally ill individual selling their life insurance policy to a third party for a lump sum payment, typically less than the full death benefit. This arrangement allows the individual to access funds while alive. Option A) Power of attorney grants legal authority to another person to make decisions on behalf of the client, but it does not involve life insurance settlements. Option B) Beneficiary settlement is not a recognized term in the context of life insurance arrangements. Option D) Life insurance guardianship is not a standard term in the insurance industry. Educationally, understanding viatical settlements is important in pharmacology as it relates to end-of-life care and financial planning for patients with terminal illnesses like AIDS. It highlights the ethical, legal, and financial considerations that healthcare professionals should be aware of when supporting patients in such situations. This knowledge can help pharmacology students provide comprehensive care and guidance to patients and their families facing end-of-life decisions.

Correct Answer: C

Rationale: An experienced RN who is familiar with the medical unit and its protocols is the best choice for caring for a patient with acute rejection. This patient requires close monitoring and skilled care which an experienced RN can provide. The other options involve RNs who may not be as familiar with the unit or are less experienced.

Correct Answer: A

Rationale: An elevated BUN level may indicate kidney involvement which is a serious complication of SLE. The other findings are expected in SLE and do not indicate an urgent problem. CRP is a marker of inflammation and positive ANA and LE cell prep are diagnostic of SLE but do not indicate acute complications.

Correct Answer: C

Rationale: In a patient with a CD4 count less than 200, the most important nursing assessment would include monitoring for fever (option C). This is because a CD4 count below 200 indicates severe immunosuppression, specifically defining AIDS. Fever in this context could indicate an opportunistic infection, which is a common complication in patients with advanced HIV/AIDS. Monitoring for fever allows for early detection and timely intervention, which is crucial in preventing further complications and improving patient outcomes. Option A, bowel movements, is not the priority assessment in this case because while changes in bowel movements can occur with some infections, fever is a more specific and critical assessment in an immunocompromised patient. Option B, urinary output, is important for assessing hydration status and kidney function but is not the priority when considering the risk of opportunistic infections in a patient with severe immunosuppression. Option D, blood pressure, is essential for monitoring overall hemodynamic status, but it is not the most crucial assessment in a patient with a CD4 count less than 200, where infection surveillance is paramount. Educationally, understanding the significance of CD4 counts and their implications on a patient's immune status is vital in pharmacology and nursing practice. This scenario highlights the importance of prioritizing assessments based on the patient's condition and the potential complications they may be at risk for due to their immunocompromised state. It emphasizes the need for comprehensive and targeted assessments to provide holistic care to patients with complex medical conditions like HIV/AIDS.
