The nurse is preparing to administer a unit of packed red blood cells (PRBC's) to a patient whose blood type is A- (negative). The nurse knows that this patient can receive transfusions from which blood types? (SELECT ALL THAT APPLY).
O-
AB -
A+
A-
O+
Correct Answer : A,D
A) O- (O negative):
A person with blood type A- can safely receive blood from a universal donor blood type, which is O-. This is because O- has no A, B, or Rh antigens on the surface of its red blood cells, making it compatible with any ABO blood group. The Rh negative status is also compatible, as the recipient is also Rh-negative.
B) AB- (AB negative):
A person with blood type A- cannot receive blood from someone with AB-. This is because the AB- blood type contains both A and B antigens on the surface of red blood cells, which could cause an immune reaction in a person with A- blood, whose immune system will react against the B antigen. Therefore, AB- is not compatible with A- blood.
C) A+ (A positive):
A person with A- blood cannot receive blood from an A+ donor, because the A+ blood contains the Rh positive antigen. If a person with A- blood receives Rh-positive blood, they will form antibodies against the Rh factor, leading to a hemolytic transfusion reaction. Therefore, A+ is not compatible with A- blood.
D) A- (A negative):
A person with A- blood can receive blood from another A- donor, because both share the A antigen and are Rh-negative. This is a perfect match and poses no risk of a transfusion reaction.
E) O+ (O positive):
A person with A- blood cannot receive blood from an O+ donor, because the O+ blood contains the Rh-positive antigen. This could cause an immune reaction in a person with A- blood, leading to the production of anti-Rh antibodies. Therefore, O+ is not compatible with A- blood.

Correct Answer is B
Explanation
A) Begins training to prepare to run a marathon next year:
This response is not characteristic of the stage of anger. Instead, this behavior suggests denial or possibly bargaining, as the client may be attempting to maintain a sense of normalcy or even hope in the face of a terminal illness like Amyotrophic Lateral Sclerosis (ALS).
B) Refuses to attend church and states that "his faith has failed him":
This statement reflects the anger stage of Kubler-Ross’s five stages of grief. During the anger stage, individuals often experience intense feelings of frustration, helplessness, and resentment about their situation. They may direct these emotions towards others, including higher powers or themselves. In this case, the client is expressing anger by blaming his circumstances and feeling abandoned by his faith, a common reaction when facing an irreversible condition like ALS.
C) Promises God to give up smoking if allowed to live until their children are married:
This behavior represents the bargaining stage of grief, not anger. In the bargaining phase, individuals may attempt to negotiate with a higher power or themselves, making promises or deals in exchange for a prolongation of life or a desired outcome. The client is trying to strike a "deal" by making promises for future behavior in exchange for a specific wish, reflecting bargaining rather than anger.
D) Gathers the family together in order to discuss what their last wishes are:
This scenario aligns more with the acceptance stage of grief. In the acceptance stage, individuals come to terms with their diagnosis and begin to make plans for the end of their life. The act of discussing last wishes indicates that the client is accepting the reality of their condition and preparing for what is to come.
Correct Answer is A
Explanation
A) CD4 count of less than 200 cells/uL, and new diagnosis of pneumocystis pneumonia:
A CD4 count of less than 200 cells/uL and the diagnosis of a severe opportunistic infection, such as pneumocystis pneumonia (PCP), are major criteria for the diagnosis of acquired immunodeficiency syndrome (AIDS). AIDS is the final stage of HIV infection, where the immune system is severely compromised, and the individual is highly susceptible to opportunistic infections like PCP, tuberculosis, and others. The CD4 count, which measures the number of immune system cells (specifically T-helper cells), is used to monitor disease progression, with values below 200 cells/uL indicating a diagnosis of AIDS.
B) CD4 count of 1200 cells/uL and a new diagnosis of hepatitis A:
While hepatitis A is an important condition that should be managed, it is not an opportunistic infection associated with AIDS. A CD4 count of 1200 cells/uL is within the normal range (500-1800 cells/uL), indicating that the immune system is not severely compromised.
C) Low grade fever with the diagnosis of influenza A:
A low-grade fever and a diagnosis of influenza A do not indicate AIDS. Influenza is a viral infection that can affect both individuals with and without HIV. It is common to experience flu-like symptoms in the early stages of HIV infection, but the presence of a fever and influenza does not confirm AIDS. A low-grade fever is also not specific to AIDS or opportunistic infections.
D) New atopic dermatitis and a white blood count of 11 million/mm³:
Atopic dermatitis is a chronic inflammatory skin condition that is not specifically associated with HIV or AIDS. The white blood cell (WBC) count of 11 million/mm³ is elevated, but this alone does not confirm a diagnosis of AIDS. Elevated WBC counts can occur with various conditions, including infections and allergic reactions, but they are not a diagnostic feature of AIDS.
