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.)

Answer and Explanation

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. An increased heart rate can be a sign of dehydration and would not indicate that IV fluid replacement has been effective.
B. Excessive thirst is a symptom of dehydration and would not indicate that IV fluid replacement has been effective.
C. Moist oral mucous membranes indicate improved hydration status and are a positive response to IV fluid replacement.
D. Decreased blood pressure is a sign of dehydration and would not indicate that IV fluid replacement has been effective.

A. “Use a nasal decongestant 15 minutes before the medication if you have a stuffy nose." B. "Plan to self-administer this medication for the next 6 months." C. "Lie down for 1 hour after administering the medication." D. "Administer the medication into one nostril once per week."

Correct Answer is D

Explanation

A. “Use a nasal decongestant 15 minutes before the medication if you have a stuffy nose": This statement is not necessary for the administration of nasal cyanocobalamin. Nasal decongestants are not routinely recommended before administering nasal medications.
B. "Plan to self-administer this medication for the next 6 months": While the duration of treatment for pernicious anemia may vary, specifying a timeframe of 6 months for self- administration is not appropriate without considering individualized treatment plans.

C. "Lie down for 1 hour after administering the medication": There is no need for the client to lie down after administering nasal cyanocobalamin. This instruction is not necessary and may not be practical.
D. "Administer the medication into one nostril once per week": This is the correct instruction for administering nasal cyanocobalamin. It is typically given once weekly into one nostril. This
method provides a convenient and effective route for vitamin B12 supplementation in clients with pernicious anemia.
