A nurse is preparing to administer ceftriaxone 1g via intermittent IV bolus over 60 min. Available is 1 g ceftriaxone sodium in 250 mL dextrose 5% in water. The nurse should set the pump can deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

A. Hemoglobin and hematocrit count:
Hemoglobin and hematocrit levels are useful in assessing overall blood volume and oxygen-carrying capacity. While these tests can help identify anemia or other hematologic abnormalities that might occur in HIV-infected individuals, they do not provide specific information regarding the stage of HIV infection or the immune function. Therefore, they are not the most helpful for determining the stage of the disease.

B. CD4+ count cell:
The CD4+ count is the most important laboratory test for assessing the progression of HIV. CD4+ T cells are critical components of the immune system, and their count reflects the level of immune suppression in the body. As HIV progresses, the CD4+ count decreases, making the individual more vulnerable to opportunistic infections. A low CD4+ count (typically below 200 cells/mm³) indicates that the individual has progressed to acquired immunodeficiency syndrome (AIDS). Therefore, the CD4+ count provides the most direct insight into the stage of HIV infection.

C. Western blot:
The Western blot test is used to confirm an HIV diagnosis after an initial positive screening test, such as the ELISA. It is not used to assess the stage of the disease. While it helps to confirm the presence of HIV antibodies, it does not provide information about immune function or the progression of the disease.

D. Enzyme-linked immunosorbent assay (ELISA):
The ELISA is a screening test used to detect antibodies against HIV. If the ELISA test is positive, it is usually followed by a confirmatory test (such as the Western blot). While ELISA is important for diagnosing HIV infection, it does not provide information about the current stage or progression of the disease. Therefore, it is not the most helpful test for assessing the stage of HIV infection once the diagnosis is established.

A. Have the client lay prone for 30 minutes. 3-4 times a day:
This statement is correct. Lying prone (on the stomach) for 30 minutes several times a day helps to prevent hip flexion contractures, which are common complications after an above-the-knee amputation. By lying prone, the residual limb is stretched and the hip joint is kept in an extended position, which helps maintain proper alignment and reduces the risk of contractures. This is a key part of postoperative care to promote optimal positioning and rehabilitation.

B. Continue using the limb prosthesis even if the skin appears irritated:
This statement is incorrect. If the skin becomes irritated or damaged, the prosthesis should not be used until the skin has healed. Continued use of the prosthesis in the presence of skin irritation can cause further damage, leading to ulcers or infections. It is essential to regularly check the residual limb for irritation, redness, or sores and adjust the prosthesis as needed. If irritation is present, the prosthesis should be removed, and appropriate skin care should be provided.

C. Withhold medication for phantom limb pain as it isn't real pain:
This statement is incorrect. Phantom limb pain is real and a common experience for individuals after an amputation. It occurs when the brain perceives pain sensations in the area where the limb used to be, even though the limb is no longer there. Phantom limb pain is often treated with pain medications, including analgesics, anticonvulsants, or antidepressants, and should not be withheld. Proper management of phantom limb pain is important for the client's comfort and overall well-being.

D. Keep the residual limb elevated to achieve as close to 90-degree hip flexion as possible:
This statement is incorrect. While it is important to elevate the residual limb after surgery to reduce swelling, it should not be elevated to the point where the hip joint is flexed to 90 degrees. Elevating the limb too much or for prolonged periods can increase the risk of developing a hip flexion contracture, which would impair mobility. The residual limb should be elevated slightly, but the hip joint should not be excessively flexed. Ideally, the limb should be positioned in a neutral or extended position when elevated.
