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 A
Explanation
Choice A reason: Primary intention is the correct answer, because it is the type of wound healing that occurs when the wound edges are approximated and closed with sutures, staples, or glue. Primary intention is the fastest and most effective way of wound healing, as it minimizes tissue loss, infection, and scarring.
Choice B reason: Secondary intention is not the correct answer, because it is the type of wound healing that occurs when the wound edges are not approximated and left open to heal by granulation, contraction, and epithelialization. Secondary intention is the slowest and least effective way of wound healing, as it results in more tissue loss, infection, and scarring.
Choice C reason: Tertiary intention is not the correct answer, because it is the type of wound healing that occurs when the wound edges are initially left open and then closed with sutures, staples, or glue after a period of time. Tertiary intention is a delayed form of primary intention, and it is used when the wound is contaminated, infected, or requires drainage.
Choice D reason: Binary intention is not the correct answer, because it is not a real term for wound healing. Binary intention is a madeup term that does not describe any specific process or outcome of wound healing.
Correct Answer is C
Explanation
Choice A reason: The client is in a private room is not an observation that requires further action by the nurse, because it is appropriate and desirable. The client with reduced immunity should be in a private room, as it can reduce the exposure to pathogens or allergens that may cause infection or inflammation. The client with reduced immunity has a weakened or impaired immune system, which makes them more susceptible and vulnerable to infection. The private room can also provide privacy, comfort, and security for the client.
Choice B reason: The client has a dedicated vital signs machine is not an observation that requires further action by the nurse, because it is appropriate and desirable. The client with reduced immunity should have a dedicated vital signs machine, as it can prevent the crosscontamination or transmission of pathogens or allergens that may cause infection or inflammation. The vital signs machine is a device that measures the blood pressure, pulse, temperature, and oxygen saturation of the client. The vital signs machine can be contaminated by the blood, body fluids, or secretions of the client or other clients, and can harbor bacteria, viruses, or fungi. The dedicated vital signs machine can also ensure the accuracy, consistency, and availability of the measurements for the client.
Choice C reason: The client has a vase of fresh flowers on the table is an observation that requires further action by the nurse, because it is inappropriate and undesirable. The client with reduced immunity should not have a vase of fresh flowers on the table, as it can increase the exposure to pathogens or allergens that may cause infection or inflammation. The fresh flowers are a source of mold, pollen, or insects, which can trigger allergic reactions, respiratory distress, or skin irritation. The fresh flowers can also contain bacteria, viruses, or fungi, which can infect the client through inhalation, ingestion, or contact. The vase of fresh flowers should be removed from the room and replaced with artificial flowers, pictures, or cards.
Choice D reason: There is hand sanitizer by the door is not an observation that requires further action by the nurse, because it is appropriate and desirable. The client with reduced immunity should have hand sanitizer by the door, as it can promote the hand hygiene and infection prevention of the client and others. Hand sanitizer is a product that contains alcohol or other agents that can kill or reduce the number of pathogens or allergens that may cause infection or inflammation. Hand sanitizer should be used by the client, the staff, and the visitors before and after entering or leaving the room, or after touching any objects or surfaces in the room.
