Question

A client is to receive antivenin following a snake bite. Before administering the antivenin, the nurse should give priority to: A. Administering a local anesthetic B. Checking for an allergic response C. Administering an anxiolytic D. Withholding fluids for 6-8 hours

Short answer

Answer: B. Checking for an allergic response.

Step-by-step solution

Analyze each option individually

We will analyze each option to determine its importance and relevance to the situation. Option A: Administering a local anesthetic. - A local anesthetic can help with pain management, but it may not be the most critical action to take before administering antivenin. Option B: Checking for an allergic response. - Allergic reactions to antivenin can be severe. Checking for an allergic response before administering antivenin is crucial to prevent life-threatening reactions such as anaphylaxis. Option C: Administering an anxiolytic. - An anxiolytic might help the patient to stay calm, but it is not the most important action to take before applying antivenin. Option D: Withholding fluids for 6-8 hours. - There is no strong medical rationale for withholding fluids before administering antivenin.

Identify the priority

Based on the analysis of each option, we can determine that the most important action for a nurse to take before administering antivenin is option B, checking for an allergic response. Allergic reactions to antivenin can be severe and life-threatening, so testing for an allergic response should be a priority in this situation. So, the correct answer is: B. Checking for an allergic response.

Key concepts

Antivenin Administration

Antivenin is a crucial treatment used in cases of venomous snake bites, where it neutralizes the venom's toxic effects. Before the administration of antivenin, it is essential for the healthcare provider to be well-informed about the procedure and patient considerations to ensure effectiveness and safety. The process involves diluting the antivenin in an IV bag and administering it slowly to mitigate potential side effects. Preparation is key, and understanding the specific type of venom involved can help determine the right type of antivenin. Important factors include:

• Correct identification of the snake species involved, as different antivenins work for specific types of venom.
• Monitoring the patient's vital signs regularly during and after the administration, as changes can indicate complications.
• Being aware of any pre-existing conditions that might affect the treatment, such as allergies or chronic health issues.

Allergic Response

Allergic responses to antivenin are a significant concern because they can be severe and even life-threatening. Healthcare providers must be vigilant in recognizing and managing potential allergic reactions. Common symptoms of an allergic response may include:

• Rash or hives
• Difficulty breathing
• Swelling of the face, lips, or throat
• Rapid heart rate
• Anaphylaxis, which is a severe, rapid allergic reaction that can be fatal

To prevent these negative effects, a skin test may be performed prior to full dosage administration. This test helps in assessing whether the patient might react negatively to the antivenin. Interventions in case of an allergic response involve discontinuing the antivenin immediately and administering medications such as antihistamines or epinephrine to counteract the symptoms.

Nursing Priorities

The primary responsibility of nurses when it comes to administering antivenin is the safety and well-being of the patient. Therefore, prioritizing tasks appropriately can make a significant difference in patient outcomes. Before administering antivenin, the priority should be to assess for allergic reactions, which entails:

• Gathering a detailed patient history to identify previous allergic reactions or sensitivities.
• Conducting thorough checks for skin reactions or respiratory issues as indicators of potential allergies.
• Educating the patient and their family about the signs of allergic reactions and the importance of immediate reporting.

Apart from monitoring for allergies, nurses must also focus on continuous patient monitoring during the administration, ensuring equipment is functioning correctly, and being prepared to intervene swiftly if complications arise.

Patient Safety

Patient safety is the top priority in any healthcare setting, especially when administering potentially volatile treatments like antivenin. Several measures are essential to uphold safety standards:

• Performing a comprehensive assessment of the patient’s medical history for allergy risks and concurrent medications.
• Ensuring that emergency equipment, such as a defibrillator and oxygen tank, is readily available in case of severe allergic reactions or anaphylaxis.
• Educating patients on what to expect during treatment and potential side effects, so they are prepared and can assist in their care by reporting changes.
• Documenting all findings and changes accurately and promptly so that any necessary adjustments to treatment can be made quickly.

These steps help in reducing risks and promoting a safe recovery environment for patients undergoing antivenin therapy, ensuring that the benefits of the treatment outweigh the potential risks.
