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. Hypomagnesemia: While lithium can affect magnesium levels, starting a new exercise program is not typically associated with hypomagnesemia. Hypomagnesemia may result in muscle weakness, tremors, and cardiac dysrhythmias.
B. Hypocalcemia: Starting a new exercise program is not typically associated with hypocalcemia. Hypocalcemia may present with muscle cramps, tetany, and seizures.
C. Hyponatremia: Starting a new exercise program may lead to dehydration and electrolyte imbalances, including hyponatremia (low sodium levels). This can have profound effects on patients taking lithium. Symptoms of hyponatremia include weakness, confusion, and seizures.
D. Hypokalemia is not a common occurrence among individuals doing exercise.
Correct Answer is A
Explanation
A. Hypotension: Hypotension can occur as an adverse effect of fentanyl, particularly if the client experiences excessive sedation or respiratory depression. Fentanyl is a potent opioid analgesic
that can cause vasodilation and a decrease in blood pressure, especially when used in high doses or in susceptible individuals.
B. Tachycardia: Tachycardia is not a typical adverse effect of fentanyl. Opioids like fentanyl typically cause bradycardia or have minimal effects on heart rate.
C. Diarrhea: Diarrhea is not a common adverse effect of fentanyl. Opioids more commonly cause constipation due to their effects on gastrointestinal motility.
D. Insomnia: Insomnia is not a typical adverse effect of fentanyl. Opioids typically cause sedation and can lead to drowsiness or somnolence, especially during initial use or when administered in high doses.
