Correct Answer: B

Rationale: To calculate the correct dosage, first, determine the total daily dose: 1.5 grams = 1500 mg. Since the medication is 200 mg/5 ml, for 1500 mg, the nurse needs to administer 1500/200 = 7.5 times the 5 ml dose. Therefore, 7.5 x 5 ml = 37.5 ml total daily dose. To administer this every 8 hours, divide 37.5 ml by 3 (8 hours intervals in a day) to get 12.5 ml to be administered every 8 hours. Choice A, C, and D are incorrect as they do not reflect the correct calculation of the dose based on the prescription and the available concentration.

Correct Answer: C

Rationale: The correct action for the nurse to take first in this situation is to stop the feeding infusion. Coughing in a client with a nasogastric tube can indicate aspiration, which can be a serious complication. By stopping the feeding infusion immediately, the nurse can prevent further aspiration and related complications. Auscultating breath sounds or turning the client to the side may be necessary actions but addressing the feeding infusion is the priority. Notifying the healthcare provider can be done after the immediate issue of potential aspiration is managed.

Correct Answer: A

Rationale: Administering the prescribed analgesic when requested reflects the nurse's value of client autonomy over veracity. This choice respects the client's right to manage their pain as they see fit. Enrolling the client in a substance abuse program (Choice B) assumes substance abuse without evidence and infringes on the client's autonomy. Providing a placebo (Choice C) violates the principle of beneficence and autonomy by deceiving the client. Documenting the frequency of medication requests (Choice D) is important for assessment but does not directly address the client's autonomy in managing their pain.

Correct Answer: B

Rationale: The correct answer is to notify the healthcare provider if there is any drainage at the catheterization site. Drainage at the site can be a sign of infection, which needs prompt evaluation and treatment. Choices A, C, and D are not as crucial as identifying and reporting any drainage, which is more directly related to potential complications post-cardiac catheterization.
