Correct Answer is A

Explanation

A. Verify dosage based on weight calculation. This is the most critical safety action, as pediatric dosages are often weight-based to prevent overdosing or underdosing, ensuring the child's safety and the medication's efficacy.

B. Make sure that the medication has a barcode. While barcode scanning is important to verify the correct medication, it is a secondary action compared to ensuring the correct dosage based on weight.

C. Have a glass of water at the bedside. While having water available can be helpful, especially for oral medications, it is not a critical safety action. The focus should be on the correct dosage.

D. Ask the child if they have taken this medication before. While it can be useful to know a child's previous experience with a medication, this is not a priority safety action compared to verifying the correct dose.

A. blocking agents B. palliative care medications C. diagnostic medications D. synergistic medications.

Correct Answer is A

Explanation

A. Blocking agents: Antagonist medications block the action of other substances, typically by binding to receptors without activating them, thus preventing other substances from binding.

B. Palliative care medications: These medications are used to relieve symptoms in patients with serious illnesses but do not describe how antagonist medications work.

C. Diagnostic medications: These are used in diagnostic tests and procedures but do not describe the action of antagonists.

D. Synergistic medications: Synergistic medications enhance the effects of each other when used together. This is the opposite of what antagonists do, as antagonists typically inhibit effects.
