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 A
Explanation
A) Take the prescribed anticoagulant specifically as directed:
Clients with mechanical heart valves are at an increased risk of developing blood clots, and therefore, anticoagulation therapy (often warfarin or another blood thinner) is necessary to prevent thromboembolic events. It is essential for the client to take the prescribed anticoagulant exactly as directed, ensuring therapeutic levels are maintained while minimizing the risk of bleeding.
B) Stop taking your antihypertensive medications until checking:
This instruction is not appropriate after heart surgery. Antihypertensive medications are typically necessary to manage blood pressure and reduce the strain on the heart. Stopping antihypertensive medications without consulting the healthcare provider could result in elevated blood pressure, which can put undue stress on the heart, especially after valve replacement surgery.
C) Avoid lifting objects ten pounds or greater for two days:
This statement is not appropriate for a client who has undergone open heart surgery. After heart surgery, particularly valve replacement, the client may be advised to avoid lifting heavy objects for a period of time (often 4-6 weeks) to prevent strain on the incision site and the heart. Two days of restriction is insufficient; longer periods of activity limitation are usually required to ensure proper healing.
D) Take your immunosuppressive medications daily in the morning:
Immunosuppressive medications are not typically prescribed for clients with mechanical heart valves. Immunosuppressive drugs are usually prescribed for clients who have had organ transplants (e.g., kidney, liver) to prevent organ rejection. Since the client in this scenario had a mitral valve replacement, immunosuppressants are not usually indicated unless there are specific complications, such as endocarditis or other infections.
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.
