The nurse is caring for a client who had a cholecystectomy two days ago. The client is febrile, reporting upper abdominal pain radiating to the back and has had three episodes of vomiting in the last 8 hours. The nurse reviews the client's serum amylase and lipase level results which are twice the normal value. Based on these findings, the nurse should recognize the client is exhibiting symptoms of which condition?

Choice A reason: This is incorrect because the humoral immune response involves B cells that produce antibodies against specific antigens. However, AIDS affects the cellular immune response, which involves T cells that activate other immune cells and directly kill infected cells.

Choice B reason: This is correct because AIDS is caused by human immunodeficiency virus (HIV), which infects and destroys CD4+ T cells, also known as helper T cells. These cells are essential for initiating and regulating both humoral and cellular immunity. Without enough CD4+ T cells, the body cannot mount an effective response against pathogens, especially opportunistic infections that take advantage of a weakened immune system.

Choice C reason: This is incorrect because bone marrow suppression of white blood cells is not a direct consequence of AIDS. However, some drugs used to treat AIDS, such as zidovudine, may cause bone marrow suppression as a side effect.

Choice D reason: This is incorrect because exposure to multiple environmental infectious agents does not cause AIDS. However, people with AIDS are more susceptible to infections from various sources due to their impaired immune system.

Choice A reason: Place the client in a room near the elevator: This does **not** promote client safety, because it exposes the client to more noise and disturbance, which can increase stress and blood pressure. A quiet and calm environment is preferable for stroke clients.

Choice B reason: Complete a swallow study before giving anything by mouth: This **promotes** client safety, because it assesses the client's ability to swallow and prevent aspiration. Stroke clients may have impaired swallowing due to facial weakness or sensory loss.

Choice C reason: Provide a call button kept within reach: This **promotes** client safety, because it allows the client to communicate their needs and request assistance when needed. Stroke clients may have limited mobility or vision, which can increase their risk of falls or injuries.

Choice D reason: Initiate use of the bed alarm: This **promotes** client safety, because it alerts the staff if the client tries to get out of bed without assistance. Stroke clients may have impaired judgment or balance, which can lead to falls or accidents.

Choice E reason: Place client belongings out of reach: This does **not** promote client safety, because it makes the client feel frustrated and helpless. Stroke clients may have difficulty reaching for their belongings due to hemiparesis or hemiplegia, which can affect their self-care and independence. The nurse should place the client's belongings within reach on their unaffected side and encourage them to use them as much as possible.

Choice F reason: Instruct the client to call before getting up: This **promotes** client safety, because it ensures that the client has adequate support and supervision when getting up. Stroke clients may have orthostatic hypotension, which can cause dizziness or fainting when changing positions. The nurse should assist the client to get up slowly and monitor their vital signs.
