Order: Hydroxyzine 25 mg PO STAT
Available: Refer to the med label below
How many milliliters will you administer? (Insert the numerical value only)
The Correct Answer is ["12.5"]
Desired dose = 25 mg
Available concentration = 10 mg per 5 mL
- Calculate the concentration in mg/mL:
Concentration (mg/mL) = Available dose / Available volume
= 10 mg / 5 mL
= 2 mg/mL
Volume to administer = Desired dose / Available concentration
= 25 mg / 2 mg/mL
= 12.5 mL

Correct Answer is B
Explanation
A. Instruct the patient to limit their fluid intake: Limiting fluids can worsen secretion thickness and impair mucociliary clearance. Hydration is essential for thinning secretions and supporting the action of mucolytics like Acetylcysteine.
B. Perform chest physiotherapy: Chest physiotherapy, including percussion and postural drainage, helps mobilize loosened secretions following Acetylcysteine administration. This facilitates airway clearance and improves ventilation and oxygenation.
C. Instruct the patient to avoid coughing to prevent airway irritation: Coughing is a natural and beneficial response that helps expel mucus after mucolytic therapy. Inhibiting the cough reflex can lead to secretion retention and airway obstruction.
D. Administer a bronchodilator: While bronchodilators may be helpful in patients with bronchospasm, they are not required after every dose of Acetylcysteine. Chest physiotherapy is more directly effective in clearing mucus after mucolytic administration.
Correct Answer is ["B","D","E","F"]
Explanation
A. Right Pharmacy: While it is important for medications to be obtained from a reliable pharmacy, "Right Pharmacy" is not one of the 10 rights of medication administration. The focus is on ensuring the correct administration process by the nurse or healthcare provider.
B. Right Medication: This is one of the core rights and ensures that the patient receives the exact medication that was prescribed. Verification is essential to avoid medication errors and adverse drug events.
C. Right Physician: Although having accurate prescriptions from a qualified provider is essential, "Right Physician" is not part of the 10 rights. The emphasis is on correct administration to the patient, not the prescriber’s identity.
D. Right Time: Administering medication at the correct time is critical for maintaining therapeutic drug levels, preventing underdosing or overdosing, and optimizing effectiveness especially for time-sensitive medications like insulin or antibiotics.
E. Right Route: Ensuring the medication is given via the prescribed route (oral, IV, subcutaneous, etc.) is vital for proper absorption, action, and safety. Errors in route can lead to severe complications or therapeutic failure.
F. Right Dose: Administering the correct dose is fundamental to achieving the desired therapeutic effect and avoiding toxicity or subtherapeutic dosing. Dosage must always match what is prescribed and appropriate for the patient's age, weight, and condition.
