A child with a ventriculoperitoneal shunt complains of headache and blurry vision and now experiences irritability and sleeping more than usual. The parents ask the nurse what they should do. Select the nurse's best response.

Give her some acetaminophen and see if her symptoms improve. If they do not improve, bring her to the healthcare provider's office.

You should immediately take her to the emergency department because these may be symptoms of a shunt malfunction.

It is common for girls to have these symptoms, especially before beginning their menstrual cycle. Give her a few days and see if she improves.

You are probably worried that she is having a problem with her shunt. This is very unlikely because it has been working well for 9 years.

The correct answer is: b) You should immediately take her to the emergency department because these may be symptoms of a shunt malfunction.
