Answer to Question 1
Correct Answer: 2
Rationale 1: Nonsteroidal anti-inflammatory drugs (NSAIDs) inhibit the synthesis of prostaglandins, and do not affect histamine.
Rationale 2: Histamine dilates blood vessels causing capillaries to become more permeable. The affected area may become congested with blood.
Rationale 3: Histamine dilates, not constricts, vessels, causing capillaries to become more permeable.
Rationale 4: Histamine is primarily stored in mast cells, not phagocyte cells.
Answer to Question 2
Correct Answer: 4
Rationale 1: Acetaminophen (Tylenol) is the preferred antipyretic drug for infants and children.
Rationale 2: The nurse can answer the mother's question; it is not necessary to refer to the pediatrician.
Rationale 3: It is not fine to use the same medicine for both children because the concentration of medication is different.
Rationale 4: Infant drops should be used for the baby; they have a different concentration of medication than the liquid preparations.
