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 D
Explanation
A. Increase the oxygen delivery by 10%: While hypoxemia is present, simply increasing oxygen may be insufficient for a client who is difficult to arouse and in severe respiratory distress. Immediate advanced airway intervention is a higher priority.
B. Administer PRN nebulizer treatment: Bronchodilators can improve airway obstruction but will not rapidly correct profound hypoxemia or altered mental status in a critically decompensating client. This intervention alone is not adequate.
C. Complete neurological assessment: Assessing neurological status is important, but the client’s low oxygen saturation and decreased responsiveness indicate a life-threatening situation that requires immediate intervention before completing a full assessment.
D. Prepare for rapid sequence intubation: The client exhibits severe hypoxemia, high respiratory rate, and decreased level of consciousness—signs of impending respiratory failure. Rapid sequence intubation ensures airway protection and adequate ventilation, which is the priority action to prevent respiratory arrest.
Correct Answer is C
Explanation
A. Repeat the heel stick for glucose in one hour: Delaying intervention to recheck glucose places the infant at risk for worsening hypoglycemia, which can lead to seizures or brain injury. Immediate corrective action is required to stabilize glucose levels.
B. Offer nipple feedings of 10% dextrose: Dextrose feedings are typically reserved for infants who cannot tolerate oral feeds or whose glucose does not improve with routine feeding. Initial management of mild neonatal hypoglycemia focuses on early and frequent feeding with breast milk or formula.
C. Begin frequent feedings of breast milk or formula: Early, frequent feeding is the first-line intervention for mild hypoglycemia in infants of diabetic mothers. It helps stabilize blood glucose by providing a steady carbohydrate source and prevents further decline without requiring IV therapy unless feeding is ineffective.
D. Assess for signs of hypocalcemia: Hypocalcemia can occur in infants of diabetic mothers but usually develops later, not within the first 30 minutes after birth. The current glucose level of 40 mg/dL indicates hypoglycemia.
