A nurse is planning to administer medications to a client who weighs 198 lb. The prescription reads, "filgrastim 5 mcg/kg, subcutaneous, daily." Available is filgrastim 300 mcg/mL. How many mL should the nurse plan to give with each dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["1.5"]
Convert the client's weight from pounds to kilograms by dividing by 2.2. 198 lb / 2.2 = 90 kg
Calculate the dose of filgrastim in micrograms by multiplying the client's weight in kilograms by the prescribed dose per kilogram. 90 kg x 5 mcg/kg = 450 mcg
Calculate the volume of filgrastim in milliliters by dividing the dose in micrograms by the concentration of the available solution. 450 mcg / 300 mcg/mL = 1.5 mL
Round the answer to the nearest tenth. The nurse should plan to give 1.5 mL of filgrastim with each dose.

Correct Answer is C
Explanation
A. Prior episode of kidney stones: A history of kidney stones is not a contraindication to prednisone therapy. However, it may require monitoring due to potential fluid and electrolyte imbalances associated with corticosteroid use.
B. Taking levothyroxine orally: Taking levothyroxine orally is not a contraindication to prednisone therapy. However, concurrent use of corticosteroids and levothyroxine may require dosage adjustments of both medications due to potential interactions.
C. Has a systemic fungal infection: Corticosteroids like prednisone can suppress the immune system, increasing the risk of fungal infections and worsening existing fungal infections.
Therefore, the presence of a systemic fungal infection is a contraindication to corticosteroid therapy.
D. History of asthma: Asthma is not a contraindication to prednisone therapy. In fact, prednisone is commonly used as a treatment for asthma exacerbations. However, caution may be needed in individuals with asthma to avoid exacerbating symptoms or complications.
Correct Answer is D
Explanation
A. Hold the injector in place for 10 seconds: Holding the injector in place after administering epinephrine is not the first action the client should take. After administering epinephrine, the client should immediately seek emergency medical attention.
B. Massage the outer thigh for 10 seconds: Massaging the outer thigh is not the first action the client should take after administering epinephrine. Seeking emergency medical attention is the priority.
C. Seek immediate medical attention: After administering epinephrine for an anaphylactic reaction, the client should immediately seek emergency medical attention to receive further evaluation and treatment. Epinephrine provides temporary relief of symptoms but does not replace the need for medical evaluation and ongoing management.
D. Jab the device into the outer thigh. The client should use the epinephrine auto-injector as soon as possible after experiencing an anaphylactic reaction. The device delivers a dose of
epinephrine, which constricts blood vessels and relaxes the airways, to reverse the symptoms of anaphylaxis.
