Correct Answer: B

Rationale: Yellow or blurred vision can be a sign of digoxin toxicity. These visual disturbances are concerning as they indicate a potential adverse reaction to the medication. Recognizing this symptom promptly is crucial to prevent serious complications. Increased appetite, increased urination, and diarrhea are not typically associated with digoxin toxicity. Therefore, option B is the correct choice in this scenario.

Correct Answer: C

Rationale: Corrected Rationale: Bradykinesia is a cardinal symptom of Parkinson's disease characterized by slowness of movement. An increase in bradykinesia may indicate a worsening of the disease and the need for adjustments in medication or other interventions. Therefore, it is crucial for the healthcare professional to report this finding to the provider promptly for further evaluation and management. Weight gain, urinary retention, and dry mouth are not directly associated with levodopa/carbidopa therapy or indicative of a worsening condition in Parkinson's disease, making them less urgent findings to report to the provider.

Correct Answer: A

Rationale: Inhaling deeply and slowly after activating the MDI is the correct instruction to ensure effective delivery of the medication to the lungs. This technique helps the medication reach the lower airways where it can be most beneficial in managing COPD symptoms. Inhaling too quickly or not deeply enough may result in improper drug delivery and reduce the effectiveness of the treatment. Holding the breath for 5 seconds after inhaling the medication (Choice B) may not be necessary and could cause discomfort without additional benefits. Rinsing the mouth immediately after using the MDI (Choice C) is not necessary unless specified by the healthcare provider. Exhaling fully before placing the mouthpiece in the mouth (Choice D) is not ideal as it may result in inadequate medication delivery to the lungs.

Correct Answer: A

Rationale: The correct answer is to avoid foods high in vitamin K. Clients taking warfarin (Coumadin) should maintain a consistent intake of vitamin K to keep the medication's effectiveness stable. Foods high in vitamin K, such as leafy greens, can interfere with the anticoagulant effects of warfarin. Therefore, it is crucial for clients to avoid these foods to ensure the therapeutic effects of warfarin. Choices B, C, and D are incorrect because increasing dairy products, limiting fiber intake, or increasing protein intake do not directly impact the effectiveness of warfarin therapy and are not necessary dietary modifications for clients on this medication.

Correct Answer: A

Rationale: The correct answer is A: Avoid foods high in vitamin K. Clients taking warfarin need to be cautious with their vitamin K intake because vitamin K can counteract the effects of the medication. Therefore, it is essential to avoid foods high in vitamin K to maintain the therapeutic effects of warfarin. Choice B is incorrect because increasing dairy product intake is not specifically related to warfarin therapy. Choice C is incorrect as high-fiber foods do not interfere with warfarin therapy. Choice D is incorrect as protein-rich foods are not contraindicated with warfarin therapy.
