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 B
Explanation
Choice A reason: "I will need to limit the number of fruit servings each day." is not a statement that indicates a correct understanding of the teaching, because it is irrelevant and inaccurate. Limiting the number of fruit servings each day is not a part of the lowpurine diet, as fruits are low in purine and do not affect the uric acid levels. Fruits are also beneficial for the health, as they provide vitamins, antioxidants, and fiber.
Choice B reason: "I should avoid eating liver and other organ meats." is a statement that indicates a correct understanding of the teaching, because it is relevant and accurate. Avoiding eating liver and other organ meats is a part of the lowpurine diet, as organ meats are high in purine and can increase the uric acid levels. Uric acid is a waste product that is formed when purine is broken down in the body. High uric acid levels can cause gout, which is a type of arthritis that occurs when uric acid crystals accumulate in the joints, causing pain, inflammation, and swelling.
Choice C reason: "I can drink only white wine." is not a statement that indicates a correct understanding of the teaching, because it is incorrect and misleading. Drinking only white wine is not a part of the lowpurine diet, as white wine is not low in purine and can increase the uric acid levels. Alcohol, in general, can interfere with the excretion of uric acid by the kidneys, and can also trigger or worsen the gout attacks. Therefore, people with gout should limit or avoid alcohol consumption, regardless of the type or color of the wine.
Choice D reason: "I should choose red meat instead of poultry." is not a statement that indicates a correct understanding of the teaching, because it is incorrect and misleading. Choosing red meat instead of poultry is not a part of the lowpurine diet, as red meat is not low in purine and can increase the uric acid levels. Red meat, such as beef, pork, or lamb, is high in purine and can aggravate the gout symptoms. Therefore, people with gout should limit or avoid red meat consumption, and choose poultry, fish, or plantbased proteins instead.
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.
