A nurse is caring for a client who is receiving intermittent enteral tube feedings.
Which of the following factors places the client at risk for aspiration?

Choice A rationale:

A client who received a Mantoux test 48 hr ago and has an induration does not require immediate follow-up care. An induration at the injection site indicates a positive reaction, but further evaluation and management are necessary, not urgent.

Choice B rationale:

A client taking warfarin with an INR of 1.8 requires follow-up care. The normal range for INR in a client taking warfarin is usually 2.0 to 3.0. An INR of 1.8 suggests inadequate anticoagulation, putting the client at risk of thromboembolic events. Dose adjustment or other interventions are needed to bring the INR within the therapeutic range.

Choice C rationale:

A client scheduled for a colonoscopy and taking sodium phosphate does not necessarily require immediate follow-up care. However, sodium phosphate can cause electrolyte imbalances, so monitoring for any signs of electrolyte disturbances is essential, but it does not mandate urgent intervention.

Choice D rationale:

A client taking bumetanide with a potassium level of 3.6 mEq/L requires follow-up care. The normal range for potassium is typically 3.5 to 5.0 mEq/L. A potassium level below the normal range (hypokalemia) can lead to cardiac arrhythmias and muscle weakness. The client may need potassium supplements or dietary adjustments to correct the imbalance.

Choice A rationale:

Using a 12-point font when printing written materials is helpful for readability, especially for individuals with visual impairments. However, this action alone does not necessarily promote meaningful learning. The content and presentation style are equally important.

Choice B rationale:

Presenting information using abstract concepts can be confusing, especially for older adults. Using concrete examples and simple language facilitates better understanding. Abstract concepts are more challenging to grasp, especially for individuals who might be experiencing cognitive decline.

Choice C rationale:

Connecting new information with the client's past experiences enhances learning and retention. Relating new knowledge to familiar situations or memories helps create cognitive associations, making it easier for the client to understand and remember the information. This technique is particularly effective in promoting learning among older adults.

Choice D rationale:

Speaking loudly when addressing the client is unnecessary and can be perceived as rude or patronizing. Clear and audible speech is essential, but shouting or raising the volume excessively is not respectful and does not enhance the learning experience.
