Protamine
Vitamin K
Atropine
Epinephrine
The Correct Answer is B
A. Protamine is used to reverse the effects of heparin, not warfarin.
B. Vitamin K is the antidote for warfarin overdose, as it promotes the synthesis of clotting factors that are inhibited by warfarin.
C. Atropine is used to treat bradycardia and other conditions, but it is not used to reverse the effects of warfarin.
D. Epinephrine is used to treat severe allergic reactions (anaphylaxis) and cardiac arrest, but it is not used to reverse the effects of warfarin.

B. Quaternary prevention focuses on avoiding unnecessary medical interventions and reducing the risk of over-medicalization. Tube feeding for a special needs student is a necessary medical intervention.
C. Tertiary prevention focuses on managing and treating existing conditions to prevent further complications or disability. Helping a special needs student with tube feeding is aimed at managing their existing condition (inability to eat orally) to prevent malnutrition or other complications.

Correct Answer is C
Explanation
A. A WBC count of 5,000/mm3 is within the normal range (4,000-11,000/mm3) and is not a priority value to monitor in a client with HIV.
B. A platelet count of 150,000/mm3 is within the normal range (150,000-400,000/mm3) and is not a priority value to monitor in a client with HIV.
C. The CD4-T-cell count is a key indicator of the immune system's function in clients with HIV. A CD4-T-cell count of 180 cells/mm3 is significantly below the normal range (500-1,500 cells/mm3) and indicates a weakened immune system, which is a priority concern in clients with HIV.
D. A positive Western blot test confirms the diagnosis of HIV, but it does not provide information about the severity of the client's condition or their immune system function.
