When inflating a blood pressure cuff, the valve must be turned clockwise in order to allow air to enter the cuff and increase the pressure inside. Choosing options B or D would result in air being released from the cuff, rather than entering it. Option C is referring to the valve being pushed into the cuff to close it, rather than turn it to open. Additionally, turning the valve counter-clockwise can potentially cause damage to the cuff and make it difficult to obtain an accurate measurement. Thus, option A is the only correct option when inflating a blood pressure cuff.
