The nurse is caring for a patient with wheezes, shortness of breath, urticaria and itching after receiving a new antibiotic The nurse understands that the epinephrine in this situation would be administered intramuscularly (IM), rather than intravenously (IV) because:
IM epinephrine is the fastest route of administration
IV epinephrine is only administered during cardiac arrest
Epinephrine would not be administered in this situation
IM epinephrine is less concentrated than IV.
The Correct Answer is B
A) IM epinephrine is the fastest route of administration:
While epinephrine is often administered intramuscularly in cases of anaphylaxis and allergic reactions, the speed of action is not the primary reason for choosing this route over intravenous (IV) administration in this situation. Intramuscular administration of epinephrine allows for a rapid onset of action, but it is not necessarily the fastest route compared to IV. IV administration would act more quickly in an emergency setting where immediate blood circulation is critical, but IM is preferred in allergic reactions to prevent excessive systemic effects and to avoid rapid peaks in plasma levels.
B) IV epinephrine is only administered during cardiac arrest:
Epinephrine is generally administered intravenously during life-threatening situations such as cardiac arrest or severe shock, where immediate circulatory effects are needed. In cases of anaphylaxis, however, intramuscular (IM) administration of epinephrine is the preferred route because it allows for a more controlled absorption rate and reduces the risk of excessive blood pressure and other adverse cardiovascular effects. This is the correct rationale for why epinephrine is administered IM in the context of an allergic reaction.
C) Epinephrine would not be administered in this situation:
Epinephrine is the first-line treatment for severe allergic reactions and anaphylaxis, especially in cases where symptoms like wheezing, shortness of breath, urticaria, and itching are present. Therefore, withholding epinephrine is not an appropriate response in this situation. Immediate intervention with epinephrine is critical to reverse the symptoms of anaphylaxis and prevent further respiratory distress or cardiovascular collapse.
D) IM epinephrine is less concentrated than IV:
The concentration of epinephrine used for IM and IV administration is the same. The primary reason for choosing the IM route over the IV route is the slower absorption and the fact that it minimizes the risk of a rapid increase in systemic blood pressure and other adverse reactions. While IM epinephrine may be absorbed more slowly than IV, its concentration is appropriate for treating anaphylaxis effectively. The choice of IM is based on safety and controlled response, not on the concentration of the drug.

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 D
Explanation
A) Prolonged prothrombin time (PT):
A prolonged PT is a sign of impaired coagulation, which is common in DIC as the clotting factors are consumed. In DIC, both clotting and bleeding occur, leading to prolonged PT. Therefore, a prolonged PT does not reflect a positive outcome. A positive outcome would show normalization or improvement of the clotting profile.
B) Elevated fibrinogen level:
Fibrinogen is often decreased in DIC because it is consumed in the process of forming clots. An elevated fibrinogen level would not indicate a positive outcome in DIC. Instead, fibrinogen levels typically fall in DIC due to widespread clotting activity. A positive outcome would involve a normalization or increase in fibrinogen levels as the condition improves.
C) Decreased platelet count:
Platelet count typically decreases in DIC because platelets are used up in the formation of clots, leading to thrombocytopenia. A decreased platelet count reflects ongoing consumption of platelets and would not be a positive indicator of improvement. In a positive outcome, the platelet count would increase toward normal levels.
D) Decreased D-dimer level:
D-dimer is a product of fibrin degradation and is elevated in conditions like DIC, where abnormal clotting and fibrinolysis are occurring. A decreased D-dimer level indicates that the coagulation process is resolving, and fibrin degradation is returning to normal, reflecting a positive outcome. Monitoring the D-dimer level is a key indicator of improvement in DIC.
