A nurse is providing teaching about health promotion activities for a client who has a new diagnosis of type 1 diabetes mellitus. Which of the following statements by the client indicates an understanding of the teaching?

Choice A rationale:
Assessing the need for oral suction every 4 hours is essential in maintaining airway patency and preventing complications associated with excessive secretions. This is an appropriate action and does not require clarification.
Choice B rationale:
Checking the ventilator settings every 12 hours is necessary to ensure that the mechanical ventilation is providing adequate support for the client's respiratory needs. This prescription is appropriate and does not need clarification.
Choice C rationale:
Keeping the head of the client's bed elevated at 30° is important in preventing aspiration and ventilator-associated pneumonia. This position helps promote optimal lung expansion and improves oxygenation in ventilated clients.
Choice D rationale:
Performing oral hygiene using an alcohol-based oral rinse is not recommended for clients receiving mechanical ventilation. Alcohol-based products can be harmful if aspirated and may disrupt the normal oral flora, leading to complications. The nurse should use a non-alcohol-based oral rinse or foam swabs instead.

Choice A rationale:
A warm left leg is a normal finding and does not require immediate intervention. Warmth indicates adequate circulation to the limb.
Choice B rationale:
A pedal pulse strength of 2 in the left leg indicates diminished pulse but does not require immediate intervention. The nurse should continue to monitor the pulse and report any significant changes to the healthcare provider.
Choice C rationale:
The client's report of pain in the foot of the left leg is an expected finding due to the fractured left femur. Pain is a subjective symptom, and the nurse should address the client's pain appropriately but not intervene immediately based on this finding.
Choice D rationale:
This is the correct choice. A capillary refill time of 3 seconds in the left foot suggests impaired circulation, which could be indicative of compartment syndrome or other circulation-related issues. The nurse should intervene immediately by notifying the healthcare provider to prevent further complications.
