A nurse is assessing a client's ability to swallow. Which of the following, when selected by the nurse, indicates an understanding of the cranial nerve that tests the ability to swallow?

Choice A rationale: this is not an appropriate response because while it may reduce the intake of vitamin K, suddenly changing the client's diet drastically may not be necessary. It is essential for the healthcare provider to make any necessary adjustments to the medication based on the client's diet.

Choice B rationale: Warfarin is an anticoagulant medication that works by inhibiting the formation of blood clots. It interacts with vitamin K, which plays a crucial role in the blood clotting process. Leafy green vegetables are rich in vitamin K, and their consumption can affect the effectiveness of warfarin. The nurse should advise the client to inform her healthcare provider about her vegetarian diet and the regular consumption of leafy green vegetables. The healthcare provider will then be able to adjust the warfarin dosage accordingly to ensure that the client receives the appropriate and consistent level of anticoagulation.

Choice C rationale: while a vegetarian diet can be healthy, the specific concern here is the potential impact of vitamin K-rich foods on warfarin therapy. It's essential to address this potential interaction rather than focusing solely on the overall healthy lifestyle.

Choice D rationale: Consuming large amounts of leafy green vegetables and vitamin K-rich foods may actually reduce the effectiveness of warfarin, leading to a decreased ability to prevent blood clots. Therefore, it is crucial to consult with the healthcare provider to manage the dosage appropriately.

Choice A rationale: Tetracycline should generally be taken on an empty stomach, as certain food and beverages, including orange juice, can interfere with its absorption. The nurse should instruct the client to take tetracycline with water and on an empty stomach unless otherwise specified by the healthcare provider.

Choice B rationale: Tetracycline is an antibiotic that can make the skin more sensitive to sunlight, leading to an increased risk of sunburn and photosensitivity reactions. To prevent these adverse effects, the nurse should instruct the client to protect their skin from sunlight while taking the medication. This includes using sunscreen, wearing protective clothing, and avoiding prolonged sun exposure. It is essential to educate the client about this potential side effect to ensure their safety and minimize skin reactions during treatment.

Choice C rationale: Tetracycline does not require routine monitoring of serum drug levels. It is an antibiotic with a well-established dosing regimen, and monitoring drug levels is not necessary for its safe and effective use.

Choice D rationale: While taking tetracycline with milk or antacids may help reduce GI irritation, it can also interfere with the absorption of the medication. Therefore, it is generally recommended to take tetracycline with water and on an empty stomach to ensure optimal absorption and effectiveness.
