Most adults with human immunodeficiency virus will exhibit which of the following laboratory values?
Higherthannormal number of CD4+ Tcells and CD8+ Tcells are normal
Lowerthannormal number of CD4+ Tcells and CD8+ Tcells are normal
Lowerthannormal number of CD4+ Tcells and higher than normal CD8+ Tcells
Higherthannormal number of CD4+ Tcells and CD8+ Tcells are low
The Correct Answer is C
Choice A reason: Higherthannormal number of CD4+ Tcells and CD8+ Tcells are normal is not a laboratory value that most adults with human immunodeficiency virus will exhibit, because it does not reflect the effect of the virus on the immune system. CD4+ Tcells and CD8+ Tcells are types of white blood cells that play a key role in the immune response. CD4+ Tcells are helper cells that activate and coordinate other immune cells, while CD8+ Tcells are cytotoxic cells that kill infected or abnormal cells. Human immunodeficiency virus infects and destroys CD4+ Tcells, which impairs the immune function and increases the risk of opportunistic infections and cancers. CD8+ Tcells are not directly affected by the virus, but they may increase in number as a compensatory mechanism to fight the infection. Therefore, most adults with human immunodeficiency virus will have lowerthannormal number of CD4+ Tcells and higher than normal CD8+ Tcells.
Choice B reason: Lowerthannormal number of CD4+ Tcells and CD8+ Tcells are normal is not a laboratory value that most adults with human immunodeficiency virus will exhibit, because it does not reflect the effect of the virus on the immune system, as explained above. Lowerthannormal number of CD4+ Tcells and CD8+ Tcells are normal may indicate a condition that affects both types of Tcells, such as aplastic anemia, chemotherapy, radiation therapy, or immunosuppressive drugs.
Choice C reason: Lowerthannormal number of CD4+ Tcells and higher than normal CD8+ Tcells is a laboratory value that most adults with human immunodeficiency virus will exhibit, because it reflects the effect of the virus on the immune system, as explained above. Lowerthannormal number of CD4+ Tcells and higher than normal CD8+ Tcells may indicate the progression of the infection and the severity of the immunodeficiency. The normal range of CD4+ Tcells is 500 to 1500 cells per microliter of blood, while the normal range of CD8+ Tcells is 150 to 1000 cells per microliter of blood.
Choice D reason: Higherthannormal number of CD4+ Tcells and CD8+ Tcells are low is not a laboratory value that most adults with human immunodeficiency virus will exhibit, because it does not reflect the effect of the virus on the immune system, as explained above. Higherthannormal number of CD4+ Tcells and CD8+ Tcells are low may indicate a condition that affects CD8+ Tcells, such as leukemia, lymphoma, or corticosteroid therapy.

Correct Answer is D
Explanation
Choice A reason: This is not the priority assessment, but it is an important assessment for a client with a femur fracture. Pain is the unpleasant sensation that results from tissue damage or inflammation. Pain can affect the client's physical and psychological wellbeing and interfere with their recovery. The nurse should assess the client's pain level, location, quality, and duration using a valid and reliable pain scale. The nurse should also provide pain relief measures, such as medication, ice, elevation, or distraction, as ordered and as needed.
Choice B reason: This is not the priority assessment, but it is a relevant assessment for a client with a femur fracture. Medication history is the record of the drugs that the client is currently taking or has taken in the past, including prescription, overthecounter, herbal, or recreational drugs. Medication history can help the nurse identify any potential drug interactions, allergies, or contraindications that may affect the client's treatment and recovery. The nurse should ask the client about their medication history and document it accurately and completely.
Choice C reason: This is not the priority assessment, but it is a helpful assessment for a client with a femur fracture. Socioeconomic status is the measure of the client's income, education, occupation, and social class. Socioeconomic status can influence the client's access to health care, ability to afford treatment, compliance with therapy, and support system. The nurse should assess the client's socioeconomic status and provide appropriate referrals, resources, or assistance as needed.
Choice D reason: This is the priority assessment for a client with a femur fracture. Pedal pulses are the pulses that can be felt in the feet, such as the dorsalis pedis or the posterior tibial pulse. Pedal pulses can indicate the blood flow and perfusion to the lower extremities, which can be compromised by a femur fracture. A femur fracture can cause bleeding, swelling, or pressure that can reduce or obstruct the blood supply to the feet, leading to ischemia, necrosis, or gangrene. The nurse should assess the client's pedal pulses regularly and report any changes, such as absent, weak, or thready pulses. The nurse should also monitor the client's skin color, temperature, sensation, and movement in the feet.
Correct Answer is C
Explanation
Choice A reason: Purulent exudate is a thick, yellowgreen, or brown pus that indicates infection. It is not bloodtinged and does not drip from the wound.
Choice B reason: Serous exudate is a clear, thin, and watery fluid that is normal in the inflammatory stage of wound healing. It does not contain blood cells and is not red in color.
Choice C reason: Serosanguineous exudate is a pink or red fluid that contains both serum and blood. It is common in the proliferative stage of wound healing and may drip from the wound due to increased capillary permeability.
Choice D reason: Sanguineous exudate is a bright or dark red fluid that consists mostly of blood. It indicates active bleeding and is usually seen in traumatic or surgical wounds. It is not diluted with serum and is more viscous than serosanguineous exudate.
