The healthcare provider prescribes epoetin alfa 100 units/kg SUBQ three times a week for a client who weighs 220 lbs. The medication is available 1,000 units/mL. How many milliliters should the practical nurse (PN) administer? (Enter the numerical value only. If rounding required, round to the whole number.)
The Correct Answer is ["10"]
Convert the client's weight from pounds (lb) to kilograms (kg).
Given weight = 220 lbs
Conversion factor = 1 kg = 2.2 lb
Weight (kg) = (Weight in lb / 2.2 lb/kg)
= (220 / 2.2)
= 100 kg.
Calculate the single dose in units (units/dose).
Prescribed dose = 100 units/kg
Single Dose (units) = Weight (kg) × Dose (units/kg)
= 100 kg × 100 units/kg
= 10,000 units.
Calculate the volume in milliliters (mL) to administer per dose.
Available concentration = 1,000 units per mL
Volume (mL) = (Single Dose (units) / Available concentration (units/mL))
= (10,000 units / 1,000 units/mL)
= 10 mL.

Correct Answer is C
Explanation
A. Brown spots on hands and arms: These are common age-related changes (lentigines) and are not an urgent concern related to hot pack use or psoriatic care.
B. Areas of decreased pigmentation: Hypopigmentation can occur in psoriasis or with chronic skin changes, but it is not typically a sign of acute injury or complication from heat therapy.
C. Erythema and edematous areas: Redness and swelling indicate possible skin irritation or burns from hot packs. These findings require prompt referral to the charge nurse for assessment and intervention to prevent further injury or infection.
D. Yellow-white scales on the skin: These are characteristic of psoriatic plaques and are expected findings. They do not signal a complication from the heat therapy and do not require immediate referral.
Correct Answer is ["B","D","E","F"]
Explanation
A. When spouse died: This is related to remote memory, not orientation to person, place, or time. While it may help assess long-term memory, it does not indicate the client’s current orientation.
B. Season of the year: This assesses orientation to time, helping determine whether the client is aware of the current temporal context, which is essential for evaluating cognitive status.
C. Past surgeries: This evaluates past medical history and long-term memory rather than current orientation. It does not reflect awareness of person, place, or time.
D. Client's name: Asking the client’s name assesses orientation to self (person), a core component of determining cognitive awareness and mental status.
E. Reason for hospitalization: This question evaluates orientation to situation or circumstance, indicating whether the client understands why they are in the hospital and the purpose of current care.
F. Present location: Asking where the client is assesses orientation to place, confirming awareness of the immediate environment and safety awareness.
