CAT Exam Practice

Correct Answer: D

Rationale: The correct action for the nurse to implement in a client experiencing clear, watery diarrhea is to review the client's current list of medications. Certain medications can cause diarrhea as a side effect, so identifying any potential culprits is essential. Administering an antiemetic (Choice A) is not appropriate for diarrhea, as antiemetics are used to control nausea and vomiting, not diarrhea. Assessing for hemorrhoids (Choice B) is not the priority when the client is experiencing watery diarrhea; addressing the root cause is crucial. Checking the client's hemoglobin level (Choice C) is not the immediate action needed for this situation as it does not directly address the cause of diarrhea.

Correct Answer: B

Rationale: The correct answer is B. Consistency in vitamin K intake is crucial for clients on warfarin to maintain stable anticoagulation levels. Option A is incorrect as vitamin C does not directly interact with warfarin. Option C is incorrect because although leafy greens are high in vitamin K, excessive consumption can affect warfarin's effectiveness. Option D is incorrect as any changes in diet, particularly in vitamin K intake, can impact the efficacy of warfarin.

Correct Answer: A

Rationale: The correct answer is A: 'Avoid heavy lifting for at least 6 weeks.' After abdominal surgery, it is essential to avoid heavy lifting to prevent complications such as incisional hernias and support proper healing. Choice B, 'Limit fluid intake to reduce the risk of infection,' is incorrect because adequate fluid intake is necessary for wound healing and preventing dehydration. Choice C, 'Resume normal activities as soon as possible,' is incorrect as it may increase the risk of complications and delay healing. Choice D, 'Avoid driving for at least 2 weeks,' is incorrect as the restriction on driving may vary depending on the type of surgery and individual recovery.

Correct Answer: A

Rationale: The correct signs and symptoms indicative of hyperosmolar hyperglycemic nonketotic syndrome (HHNS) include increased heart rate, visual disturbances, and decreased mentation. These symptoms are often associated with HHNS due to the high blood glucose levels. Uremic frost, a sign of advanced kidney disease, is not typically associated with HHNS. Therefore, choices B and D are incorrect. However, choice C, 'Presence of uremic frost,' is incorrect as it is not typically associated with HHNS.

Correct Answer: B

Rationale: The correct response is to provide a relevant explanation to the client. Choice B, "This shot will help relieve the pain in your feet," is the best answer because it directly addresses the client's concern about the purpose of the medication. By explaining the potential benefit of the injection, the nurse can alleviate the client's anxiety and increase their cooperation during the procedure. Choice A is incorrect as it dismisses the client's question and may escalate the situation. Choice C is not suitable as it deviates from addressing the client's immediate query. Choice D is incorrect because it fails to specifically address the client's concern regarding the medication's purpose.
