A nurse is caring for a client who has had a myocardial infarction. Upon his first visit to cardiac rehabilitation, he tells the nurse that he doesn't understand why he needs to be there because there is nothing more to do, as the damage is done. Which of the following is the correct nursing response?

Turn the client's head to the side.

The nurse should turn the client's head to the side first to prevent aspiration of oral secretions and maintain a patent airway. This is the priority action according to the airway, breathing, and circulation (ABC) principle.

Check the client's motor strength is wrong because it is not the priority action and it is not feasible during a seizure. The nurse should check the client's motor strength after the seizure to assess for any neurological deficits or postictal weakness.

Document the time the seizure began is wrong because it is not the priority action and it can be done later. The nurse should document the time, duration, type, and characteristics of the seizure, but only after ensuring the client's safety and well-being.

Loosen the clothing around the client's waist is wrong because it is not the priority action and it may not be necessary. The nurse should loosen any tight clothing that could impair breathing or circulation, but only after securing the airway and protecting the head from injury.

To calculate the volume to administer, the nurse should use the following formula:

Volume (mL) = Dose (mg) / Concentration (mg/mL) x 1000

Plugging in the given values, the nurse should get:

Volume (mL) = 400 mg / 250 mg/5 mL x 1000

Volume (mL) = 8 mL

The nurse should round the answer to the nearest whole number and use a leading zero if it applies. Therefore, the nurse should administer 8 mL of valproic acid per dose.
