Correct Answer: A

Rationale: The correct answer is A. Soaking feet daily can lead to excessive moisture, which can increase the risk of skin breakdown or infection in diabetic clients. Choices B, C, and D are all correct statements for foot care in diabetic clients. Using a mirror for daily foot checks helps in early detection of any issues, applying lotion while avoiding the area between the toes helps keep the skin moisturized without creating a risk for fungal infections, and wearing properly fitting shoes is important to prevent pressure points and potential injuries.

Correct Answer: A

Rationale: Administering an anticoagulant is the nurse's priority action in this situation. Given the client's history of DVT and the presentation of new onset shortness of breath and a productive cough, there is a concern for a pulmonary embolism, which is a life-threatening complication of DVT. Administering an anticoagulant promptly is crucial to prevent further clot formation and to manage the existing clot, reducing the risk of pulmonary embolism. While auscultating lung sounds and preparing for chest physiotherapy are important actions in respiratory assessment and management, the priority in this case is to address the potential complication of a pulmonary embolism by administering the anticoagulant. Notifying the healthcare provider can be done after initiating the immediate intervention of anticoagulant therapy.

Correct Answer: B

Rationale: The correct answer is B. Clients with duodenal ulcers should avoid spicy foods and alcohol as they can exacerbate symptoms and delay healing. Choice A is incorrect because while antacids may help with symptoms, they are not the primary focus of medication teaching for duodenal ulcers. Choice C is not directly related to medication teaching for duodenal ulcers unless antibiotics are specifically prescribed. Choice D is incorrect as stopping all food intake is not recommended and can lead to other complications.

Correct Answer: B

Rationale: Ciprofloxacin can cause crystalluria, so increasing fluid intake to 2-3 liters per day helps flush out the medication and prevent crystal formation in the kidneys. This also ensures adequate hydration, which supports the body's ability to fight the infection. Choice A is incorrect because ciprofloxacin should not be taken with dairy products as they can interfere with the absorption of the medication. Choice D is incorrect because although it's important to complete the full course of antibiotics, it's equally crucial to report any improvement in symptoms to the healthcare provider.

Correct Answer: D

Rationale: The correct answer is D. A preschooler with intermittent alertness episodes is not a suitable candidate for patient-controlled analgesia (PCA) due to their inability to effectively manage the system. In the context of terminal cancer, it is crucial for the patient to be able to utilize the PCA system appropriately to manage pain effectively. Preschoolers may not have the cognitive ability or understanding to operate a PCA pump compared to the other clients. Choices A, B, and C present clients with conditions that do not inherently impede their ability to use a PCA pump effectively.
