A nurse is caring for a client who has heart failure and a prescription for digoxin 125 mcg PO daily. Available is digoxin PO 0.25 mg/tablet. How many tablets should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

A. CD4 T cell count 180 cells/mm3: In a client with HIV, monitoring the CD4 T cell count is crucial for assessing immune function and determining the progression of the disease. A CD4 T cell count of less than 200 cells/mm3 indicates severe immunosuppression and an increased risk of opportunistic infections, making it the priority laboratory value to monitor in this client.
B. Platelets 150,000/mm3: While platelet count is important for assessing clotting function, it is not the priority laboratory value in a client with HIV. Thrombocytopenia can occur in HIV but is often secondary to other factors such as medication side effects or opportunistic infections. However, a platelet count within the normal range of 150,000/mm3 is reassuring and does not require immediate intervention.
C. WBC 5000 mm3: White blood cell (WBC) count is essential for assessing overall immune function, but it is not the priority laboratory value in a client with HIV. A WBC count of 5000 mm3 is within the normal range and does not require urgent attention.
D. Positive Western blot test: While a positive Western blot test confirms HIV infection, it does not provide information about the client's current immune status or the need for immediate intervention. Confirmatory tests such as Western blot are important for diagnosis, but they do not provide ongoing monitoring of disease progression or immune function.

A. Rotate assignment of daily caregivers: Consistency in caregivers is important for individuals with Alzheimer's disease to build trust and rapport. Rotating caregivers frequently may disrupt the client's routine and lead to increased confusion and anxiety.
B. Provide an activity schedule that changes from day to day: Consistency and routine are beneficial for individuals with Alzheimer's disease as they provide structure and predictability. A consistent activity schedule helps the client feel more secure and can reduce agitation and behavioral issues.
C. Limit time for the client to perform activities: While it may be necessary to pace activities based on the client's abilities and fatigue level, arbitrarily limiting time for the client to perform activities can be counterproductive. Instead, individualizing the pace of activities based on the client's preferences and abilities is more beneficial.
D. Talk the client through tasks one step at a time: Individuals with Alzheimer's disease often experience cognitive impairment, including difficulty with memory, attention, and problem-solving. Breaking tasks down into manageable steps and providing clear, simple instructions can help the client understand and complete activities of daily living more effectively. This intervention supports the client's independence and reduces frustration.
