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) Assess lung sounds and respiratory rate at least every 2 hours:
In a patient with Myasthenia Gravis (MG) who has undergone thymectomy, monitoring respiratory status is critical. MG is a neuromuscular disorder that can lead to respiratory muscle weakness, which may be exacerbated post-operatively. Assessing lung sounds and respiratory rate at least every 2 hours is crucial to detect early signs of respiratory compromise, including hypoventilation or atelectasis.
B) Assess and document pain level once every shift:
While pain assessment is important, especially after a thymectomy, this action alone does not directly address the immediate issue of ineffective breathing patterns. In patients with MG, respiratory complications are a priority concern. Pain management should be part of the overall plan of care, but it is secondary to monitoring respiratory function in the acute post-operative period. Pain can affect respiratory effort, but it should be managed in the context of more pressing issues like airway and breathing assessment.
C) Maintain sequential compression device (SCD's) while in bed:
While SCDs are important in preventing deep vein thrombosis (DVT) in patients who are immobile, they are not the most appropriate intervention for a client with ineffective breathing patterns. The primary concern in a post-thymectomy patient with MG is respiratory function.
D) Elevate the head of the bed ten degrees:
While elevating the head of the bed can help with comfort and potentially improve ventilation in some patients, it is not the most specific or effective intervention for managing ineffective breathing patterns in a patient with MG. For optimal respiratory function, it is typically more beneficial to elevate the head of the bed to a higher degree (e.g., 30-45 degrees) to enhance lung expansion, rather than just 10 degrees.
