A child must receive a loading dose of digoxin 30 mcg÷kg IV. The child weighs 55 lbs.

How many micrograms should the child receive?

This question tests clinical safety protocols during medication administration. It requires identifying the breach of standard documentation policies, which mandate that medications are recorded only after they have been administered to the patient, to prevent medical errors and ensure accurate, safe clinical record-keeping.

Choice A rationale

Verifying the medication against the prescription and the label is a fundamental step in the medication administration process. This action is essential for confirming the "right medication" and "right dose" to prevent dangerous medication errors and ensure patient safety.

Choice B rationale

Documentation must never occur before the medication is physically administered to the patient. Pre-documentation is a critical safety violation that creates a false record and increases the risk of error, such as omitting the dose or administering it to the wrong patient.

Choice C rationale

Scanning the bar codes on the patient's ID band and the medication label is a standard, evidence-based technological safety check. This process is designed to reduce human error by electronically verifying that the correct medication is given to the correct patient.

Choice D rationale

Checking the provider's orders and verifying doses in a reliable drug reference guide is a core competency for safe medication administration. This action demonstrates sound clinical judgment and adherence to safety practices by ensuring the dosage is appropriate before administering it to the patient.

This question focuses on the pharmacological management of opioid withdrawal. It requires identifying the use of long-acting opioid agonists, which provide a controlled, stable effect on the nervous system, helping to suppress withdrawal symptoms and reduce cravings while minimizing the potential for intoxication.

Choice A rationale

Disulfiram is a medication used to treat alcohol use disorder. It works by causing severe adverse reactions if the patient consumes alcohol. It has no pharmacological role in managing opioid withdrawal symptoms and would be entirely ineffective for this purpose.

Choice B rationale

Betalol is not a recognized medication used for managing opioid withdrawal. Medications for withdrawal are selected for their ability to interact with opioid receptors or mitigate the autonomic nervous system hyper-arousal that occurs during the process of opioid cessation in patients.

Choice C rationale

Methadone is a long-acting synthetic opioid agonist used to manage opioid withdrawal and dependence. It binds to the same receptors as heroin or morphine but has a slower onset and longer duration, helping to prevent withdrawal while reducing illicit drug cravings.

Choice D rationale

Diazepam is a benzodiazepine used for anxiety or muscle spasms. While it may sometimes be used to manage some withdrawal symptoms, methadone is the specific pharmacological intervention used for opioid withdrawal because it directly targets the underlying neurochemical dependence on opioids.
