The client, admitted to the ED, is prescribed to receive 0.5 mg epinephrine subcutaneously for treatment of a severe asthma attack. The medication for injection is supplied in a vial that contains 5 mg/mL. How many milliliters of epinephrine should the nurse administer?
Correct Answer: 0.1
Rationale: Use a proportion to determine the amount in milliliters; then multiply the extremes (outside values) and the means (inside values) and solve for X. 5 mg: 1 mL :: 0.5 mg: X mL; 5X = 0.5 mL; X = 0.1 mL; the nurse should administer 0.1 mL of epinephrine (Adrenalin).

- A. The catheter inserted in the right external jugular vein of the 2-year-old
- B. The catheter inserted in the right subclavian vein of the 4-year-old

Correct Answer: C
Rationale: A: The external jugular vein is a central IV access site. B: The subclavian vein is a central IV access site. C: TPN is a concentrated hypertonic solution containing glucose, vitamins, electrolytes, trace minerals, and protein. Because it is hypertonic, it should be administered through a central IV access site or a PICC. A major vein is used to avoid inflammatory reactions and venous thrombosis from the high-caloric and high-osmotic fluid. D: A PICC is a central IV access site.
While the nurse is completing the assessment of the child with Reye's syndrome, the parent states that multiple OTC medications were given before hospitalization to treat the child's influenza symptoms. Which medication stated by the parent is most important for the nurse to report to the HCP?
- A. Acetaminophen
- B. Bismuth subsalicylate
- C. Pseudoephedrine
- D. Diphenhydramine

Rationale: A: Acetaminophen (Tylenol) is an aspirin-free analgesic and antipyretic. B: Although the etiology of Reye's syndrome is unknown, the condition typically occurs after a viral illness, such as influenza, and is associated with aspirin (acetylsalicylic acid) use during the illness. Bismuth subsalicylate (Pepto-Bismol) contains aspirin. C: Pseudoephedrine (Sudafed) is an allergy and/or cold remedy used for nasal drying and decongestion. This does not contain aspirin. D: Diphenhydramine (Benadryl) is an antihistamine. This does not contain aspirin.
