A nurse is preparing to administer methy prednisolone 7 mg/kg/day IM in two divided doses to a school-age child who weighs 64 lb. Available is methyiprednisolone 20 mg/mL. How many mL should the nurse administer per 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 ["5.1"]
First, convert the child's weight from pounds to kilograms: 64 lb / 2.205 lb/kg = 29.02 kg
Calculate the total daily dose of methylprednisolone needed: 7 mg/kg x 29.02 kg = 203.14 mg
Calculate the dose per administration: 203.14 mg / 2 = 101.57 mg
Calculate the volume of methylprednisolone to administer per dose: 101.57 mg / 20 mg/mL = 5.0785 mL
Round to the nearest tenth: 5.0785 mL rounded to the nearest tenth is 5.1 mL.

Correct Answer is B
Explanation
A. The client can return to bed after taking the medication, but before eating:
This instruction is incorrect. After taking alendronate, the client should remain upright for at least 30 minutes to prevent irritation of the esophagus and minimize the risk of esophageal injury or reflux. Returning to bed immediately after taking the medication could increase the risk of these complications. The client should remain upright for the full 30 minutes, and this action is essential for the medication's safety and effectiveness.
B. Choose the same day of each week to take this medication:
The nurse should advise the client to take alendronate on the same day each week. This will help the client remember to take the medication regularly and consistently. Alendronate is typically prescribed as a once-weekly dose, and establishing a routine, such as choosing a specific day of the week, can improve adherence to the treatment regimen and ensure optimal therapeutic effects for osteoporosis.
C. Over-the-counter oral preparations can be taken with this medication:
Over-the-counter oral preparations, particularly calcium supplements and antacids, should not be taken with alendronate. Alendronate needs to be absorbed properly in the stomach, and taking it with other medications, especially those containing calcium, magnesium, or aluminum, can interfere with absorption. It is important that alendronate is taken alone, on an empty stomach, at least 30 minutes before any food, fluid, or other medications.
D. Take the medication at 1800, 30 min after the evening meal:
This is not correct. Alendronate should be taken in the morning, at least 30 minutes before eating, drinking, or taking any other medications. Taking it at 1800 (6:00 PM) after the evening meal would be incorrect, as the medication needs to be absorbed in an empty stomach for maximum effectiveness. Evening doses are not appropriate because of the potential for gastric irritation and decreased absorption with food and other evening medications.
Correct Answer is C
Explanation
A. Route:
The prescription clearly specifies the route as "apply topically," which means that the method of administration is already well-defined. There is no need for further clarification or addition regarding the route of administration in this case. Since it is already included in the instructions, adding this information would be redundant.
B. Time/frequency:
The prescription includes the frequency, stating that the hydrocortisone acetate cream should be applied "twice a day." Therefore, the time and frequency are already specified in the order, leaving no need for further clarification in this section. It is important to ensure that the time and frequency are correctly indicated, but in this case, the details are complete.
C. Dose/Strength:
The prescription lacks crucial information about the dose or strength of the hydrocortisone acetate cream. This is a critical piece of information, as different strengths (e.g., 1%, 2.5%) can be prescribed depending on the severity of the condition being treated. Clarifying the dose/strength is necessary to ensure that the client receives the appropriate concentration, preventing underdosing or overdosing, which could affect the treatment's effectiveness and safety.
D. Medication name:
The medication name, "hydrocortisone acetate cream," is already clearly listed in the prescription. Since it has been included in the order, there is no need for the nurse to ask the provider to add it again. The medication name is essential for correct identification, but in this scenario, it is already documented. Adding it would be unnecessary and would not improve the clarity of the prescription.
