The healthcare provider prescribes methylprednisolone 1 mg/kg IM every 12 hours for inflammation for a child who weighs 58 pounds.
The vial is labeled, "40 mg/mL.”. How many mL should the practical nurse (PN) administer with each dose? (Enter the numerical value only. If rounding is required round to the nearest tenth.)
The Correct Answer is ["0.7"]
Step 1 is: Convert pounds to kilograms. 58 pounds ÷ 2.2 pounds/kg = 26.36 kg.
Step 2 is: Calculate the total milligrams per dose. 1 mg/kg × 26.36 kg = 26.36 mg.
Step 3 is: Calculate the volume to administer per dose. 26.36 mg ÷ (40 mg/mL) = 0.659 mL.
Step 4 is: Round to the nearest tenth. 0.7 mL.

Correct Answer is D
Explanation
Choice A rationale
Cheese is a good source of calcium and protein, but it is not a primary source of iron. Iron is essential for hemoglobin synthesis, and the client's hemoglobin and hematocrit levels are below normal ranges [Hemoglobin, pregnant female > 11 g/dL ( > 110 g/L); Hematocrit, pregnant female > 33% ( > 0.33 volume fraction)], indicating iron deficiency anemia.
Choice B rationale
Cauliflower is a cruciferous vegetable rich in vitamin C and fiber, but its iron content is relatively low. While vitamin C aids in iron absorption, cauliflower itself does not provide a significant amount of dietary iron to effectively address the client's anemic status.
Choice C rationale
Carrots are well-known for their beta-carotene content, a precursor to vitamin A, and provide fiber. However, carrots are not a significant source of iron. To combat iron deficiency anemia during pregnancy, foods rich in heme iron or non-heme iron with good bioavailability are required.
Choice D rationale
Chicken, particularly the dark meat, is a good source of heme iron, which is more readily absorbed by the body compared to non-heme iron found in plant-based foods. Given the client's anemic status, increasing dietary intake of iron-rich foods like chicken is crucial for improving hemoglobin and hematocrit levels.
Correct Answer is C
Explanation
Choice A rationale
While suctioning with a bulb syringe may be indicated for secretions, in an active choking episode with a foreign body obstruction, it is not the immediate first action. Back-blows are more effective at dislodging the obstructing object by increasing intrathoracic pressure and creating an artificial cough.
Choice B rationale
Monitoring respirations for 15 seconds is a delay in critical intervention for an infant actively choking. An infant who is choking requires immediate, active intervention to clear the airway and restore effective breathing, as prolonged airway obstruction can quickly lead to hypoxia and cardiac arrest.
Choice C rationale
In a choking infant, the immediate and most effective first action is to perform three back-blows. This maneuver utilizes gravity and rapid increases in intrathoracic pressure to dislodge the foreign object from the airway, aiming to clear the obstruction quickly and restore ventilation.
Choice D rationale
Stopping the feeding and sitting the infant upright might be appropriate if the infant is merely gagging or coughing, but for active choking, this action alone is insufficient to dislodge an aspirated object. Active intervention like back-blows is required to overcome the obstruction.
