Q

A 21 year old woman has a fear of injections and has presented as she wishes to become pregnant and knows she will probably then need to have some blood taken.
You think that she has a phobic disorder and try to explain principles of exposure therapy. She says exposure won’t work for her, because if she sees a needle coming towards her she faints.

What is the explanation for the alleged fainting
episodes?

A

This is vasovagal syncope due to a diphasic response in blood-injury phobia

Practically this means that if exposure is to be attempted then something is necessary to prevent syncope - this is done by teaching the patient a technique called “applied tension”
(which prevents venous pooling, etc.):

Q

Would it be wise to offer clomipramine to a patient at risk of suicide?

A

No. TCAs are potentially much more toxic than SSRIs in overdose (marked cardiotoxicity). If the indication for use is very strong, consider offering very short repeat prescriptions and ensure safety plans are robust.

Q

Outline the principles of CBT

A

Cognitive behavioural therapy (CBT) is a type of talking therapy where patients work with a therapist to identify and challenge negative thought patterns and behaviour.

CBT is based on the idea that how we think about situations can affect the way we feel and behave. For example, if you interpret a situation negatively, you might experience negative emotions, which may lead you to act in a certain way.
