In a clinical scenario, a patient with a skin infection requires a drug that acts directly at the site of infection. Which drug form should be selected?

Appeared in: RRB Nsg. Superintendent-2026 (Shift -3rd)

Explanation

The question requires a drug that acts directly at the site of a skin infection, indicating a need for localized treatment.
Topical creams are semisolid preparations designed to be applied externally to the skin (dermal route).
This route delivers a high concentration of the active ingredient directly to the affected tissue, maximizing therapeutic effect for skin conditions.
It also minimizes systemic absorption, which reduces the risk of side effects throughout thebody.

Option A: A capsule is an oral dosage form. It is swallowed, and the drug is absorbed into the bloodstream to produce a systemic effect throughout the body, not a direct local effect on the skin.
Option B: A suppository is designed for insertion into a body cavity like the rectum or vagina. It melts at body temperature to release medication for either a local effect in that cavity or for systemic absorption.
Option D: A syrup is a liquid oral dosage form. Like a capsule, it is swallowed and absorbed through the gastrointestinal tract to produce a systemic effect.

Clinical Relevance

Nursing practice connection: Use the key finding related to Drug dosage forms and routes of administration to guide bedside assessment, documentation, and the next nursing action.
Choosing the correct drug form and route is a fundamental nursing responsibility that directly impacts patient safety and treatment efficacy.
Applying a topical agent correctly (e.g., cleaning the skin first, using a thin layer) enhances its effectiveness and prevents waste or adverse reactions.
What if? If the patient's skin infection was showing signs of spreading (e.g., red streaks, fever, chills), it would indicate a systemic infection. In that case, a topical cream alone would be insufficient, and the provider would likely prescribe a systemic antibiotic, such as an oral capsule or IV infusion.

How to Approach the Question

First, identify the key requirements from the question: the location of the problem ('skin infection') and the desired action ('acts directly at the site').
The phrase 'acts directly at the site' points to a local effect, not a systemic one.
Analyze the options based on their route of administration and type of effect.
A 'Capsule' and 'Syrup' are oral and cause systemic effects.
A 'Suppository' is for rectal/vaginal use.
A 'Topical cream' is applied to the skin for a local effect. This matches the requirements perfectly.
