Envenomation by spiders or scorpions is a public health problem in many parts of the world and is not isolated to the tropics and subtropics. Spiders and scorpions can be unintentionally transported globally, and keeping them as pets is becoming more popular, so envenomation can occur anywhere. Emergency nurses should be prepared to assess and treat patients who present with a bite or sting. This article gives an overview of the signs, symptoms and treatment of envenomation by species of arachnids that are clinically significant to humans.

Only one species of venomous snake, the adder, is indigenous to the UK, but many people keep venomous snakes as pets and others travel to places, such as the United States, where a wider variety of venomous snakes can be found.

This article offers an overview of the most common forms of envenomation in the UK and makes recommendations for the clinical care of people who have sustained snake bites.

Aim To understand the role and effect of a community mental health nurse (CMHN) deployed to work with military personnel during sea-based operations.

Method Semi-structured interviews were conducted to ascertain Royal Navy aircraft carrier military unit commanders’ perceptions and experiences of the CMHN’s role.

Findings Three mutually inclusive components are necessary to ensure successful integration of the CMHN: familiarity, trust and credibility.

Conclusion For CMHNs to function successfully and provide mental health care to sea-based military personnel, they need to demonstrate familiarity, trust and credibility. This will enhance uptake of mental health services among military personnel and ensure they are fit for service.
