The healthcare provider orders Compazine 10 mg IM now. The concentration available is Compazine 5 mg/mL. How many mL will the patient receive?

0.5 mL

4 mL

1 mL

2 mL

Answer and Explanation

The Correct Answer is D

Choice A reason: For 10 mg at 5 mg/mL: 10 ÷ 5 = 2 mL. Choice A (0.5 mL) delivers 2.5 mg (0.5 × 5), underdosing Compazine, which may fail to control nausea or psychosis, making this choice incorrect for the prescribed dose.

Choice B reason: The correct volume is 10 mg ÷ 5 mg/mL = 2 mL. Choice B (4 mL) delivers 20 mg (4 × 5), overdosing Compazine, risking extrapyramidal symptoms or sedation, making this choice incorrect and potentially harmful for safe administration.

Choice C reason: For 10 mg, the volume is 2 mL (10 ÷ 5). Choice C (1 mL) delivers 5 mg (1 × 5), underdosing Compazine, which could be ineffective for nausea or psychiatric symptoms, making this choice inadequate for the ordered dose.

Choice D reason: Calculating 10 mg ÷ 5 mg/mL = 2 mL accurately delivers the ordered 10 mg of Compazine (prochlorperazine) for nausea or psychosis. This ensures therapeutic efficacy without overdose, aligning with safe intramuscular administration, making this the correct choice.

Correct Answer is ["A","D","E"]

Explanation

Choice A reason: Electronic order entry systems reduce errors by standardizing prescriptions and flagging issues. This enhances safety, making it a correct preventive strategy.

Choice B reason: Naming and shaming create fear, discouraging error reporting and learning. Nonpunitive approaches are effective, so this is incorrect for preventing errors.

Choice C reason: Prosecuting caregivers deters transparency, hindering error analysis. Supportive tracking systems prevent errors, so this is incorrect for effective strategies.

Choice D reason: Engaging patients as informed team members improves adherence and catches errors. This collaborative approach is effective, making it a correct choice.

Choice E reason: Nonpunitive error tracking encourages reporting, identifying patterns to prevent future mistakes. This is a proven method, making it a correct choice.

A. Benzonatate [Tessalon] B. Guaifenesin [Mucinex] C. Dextromethorphan [Robitussin] D. Codeine

Correct Answer is ["A","C","D"]

Explanation

Choice A reason: Benzonatate suppresses cough by anesthetizing stretch receptors in the respiratory tract, reducing the cough reflex. It acts locally on nerve endings in the lungs and pleura, effectively decreasing cough frequency without systemic opioid effects, making it an appropriate choice for cough suppression.

Choice B reason: Guaifenesin is an expectorant, promoting mucus clearance by thinning secretions, not suppressing the cough reflex. It facilitates productive coughing rather than inhibiting it, making it ineffective for cough suppression and an incorrect choice for this indication in managing cough symptoms.

Choice C reason: Dextromethorphan suppresses cough by acting on the medulla’s cough center, reducing the urge to cough. As a non-opioid antitussive, it effectively controls non-productive cough without significant respiratory depression, making it a suitable and correct choice for cough suppression in various conditions.

Choice D reason: Codeine, an opioid, suppresses cough by acting on the central nervous system’s cough center, reducing reflex activity. It’s effective for non-productive cough but carries risks of sedation and dependency, making it a correct but cautiously used choice for cough suppression.
