A client with acquired immune deficiency syndrome (AIDS) and Pneumocystis jiroveci pneumonia has a CD4+ T cell count of 200 cells/mm³ (20%). The client asks the nurse why they have these recurring massive infections. Which pathophysiologic mechanism should the nurse describe in response to this client's question?

Reference Range:
T-helper CD4 cells [600 to 1500 cells/mm³ (60 to 75%)]

Choice A reason: Measuring capillary glucose level is not a priority action for a client with a rigid abdomen and rebound tenderness. These signs indicate peritonitis, which is a serious complication of IBD that requires immediate attention. Corticosteroids can increase blood glucose levels, but this is not an urgent concern in this situation.

Choice B reason: Encouraging ambulation in the room is not appropriate for a client with a rigid abdomen and rebound tenderness. These signs indicate peritonitis, which is a serious complication of IBD that requires immediate attention. Ambulation can worsen the pain and inflammation, and increase the risk of bowel perforation.

Choice C reason: Monitoring for bloody diarrheal stools is important for a client with IBD, but not a priority action for a client with a rigid abdomen and rebound tenderness. These signs indicate peritonitis, which is a serious complication of IBD that requires immediate attention. Bloody stools can be a sign of ulceration or bleeding in the bowel, but they are not specific to peritonitis.

Choice D reason: Obtaining vital sign measurements is the priority action for a client with a rigid abdomen and rebound tenderness. These signs indicate peritonitis, which is a serious complication of IBD that requires immediate attention. Vital signs can reveal signs of infection, inflammation, shock, and organ failure, which can guide the appropriate interventions and treatments.

- Choice A: Occupational therapist. This is correct because an occupational therapist can help the client with activities of daily living (ADLs) such as dressing, grooming, eating, and toileting. The client may have difficulty performing these tasks due to the facial droop and weakness caused by the stroke.

- Choice B: Speech therapist. This is correct because a speech therapist can help the client with communication and swallowing problems. The client has garbled speech, which indicates a possible aphasia or dysarthria. The client may also have dysphagia, which is difficulty swallowing, due to the impaired coordination of the muscles involved in swallowing.

- Choice C: Case manager. This is correct because a case manager can coordinate the client's care and discharge planning. The case manager can arrange for referrals, home health services, equipment, and follow-up appointments as needed. The case manager can also provide education and support to the client and family.

- Choice D: Physical therapist. This is correct because a physical therapist can help the client with mobility and balance issues. The client may have hemiparesis or hemiplegia, which is weakness or paralysis of one side of the body. The physical therapist can assist the client with exercises, gait training, and assistive devices to improve the client's functional status.

- Choice E: Chief nursing officer. This is incorrect because a chief nursing officer is not directly involved in the client's recovery. A chief nursing officer is a senior-level executive who oversees the nursing staff and operations of a health care organization. A chief nursing officer may have a role in quality improvement, policy development, and strategic planning, but not in individual client care.

- Choice F: Pharmacy technician. This is incorrect because a pharmacy technician is not directly involved in the client's recovery. A pharmacy technician is a health care professional who assists pharmacists with dispensing medications and other tasks. A pharmacy technician may have a role in preparing, labeling, and delivering medications, but not in providing therapy or education to the client.

- Choice G: Respiratory therapist. This is incorrect because a respiratory therapist is not directly involved in the client's recovery. A respiratory therapist is a health care professional who provides respiratory care to patients with breathing problems. A respiratory therapist may have a role in administering oxygen, nebulizers, ventilators, and other respiratory treatments, but not in addressing the client's stroke-related impairments.

- Choice H: Medical assistant. This is incorrect because a medical assistant is not directly involved in the client's recovery. A medical assistant is a health care professional who performs administrative and clinical tasks in a medical office or clinic. A medical assistant may have a role in scheduling appointments, taking vital signs, drawing blood, and performing basic laboratory tests, but not in providing rehabilitation or education to the client.
