Correct Answer: D

Rationale: The best way to handle the situation in this scenario is to move the neighboring client to a room at the end of the hall. This solution is considerate to both clients because it addresses the issue by providing a quieter environment for the client with dementia while allowing the postoperative client to rest. Choice A is inappropriate as it does not address the root cause of the problem and may not be feasible or respectful. Choice B of closing the doors may not effectively reduce the noise disturbance. Choice C of giving the complaining client sedatives should be the last resort and not the initial solution, as it does not address the underlying issue causing the disturbance.

Correct Answer: A

Rationale: Tuberculosis is an airborne infection, and placing a client with TB in a room with negative pressure airflow helps prevent the spread of the infection by containing the pathogens. This measure is crucial as it prevents the dissemination of TB droplet nuclei to other areas. Choice B, using a disposable gown for contact precautions, is important for preventing the transmission of infections spread by direct or indirect contact. Choice C, placing a client with MRSA in a private room, is essential to prevent the spread of MRSA through contact with others. Choice D, using a mask for clients with influenza, helps prevent the spread of influenza through respiratory droplets. However, negative pressure airflow is specifically required for airborne infections like TB, making it the most appropriate choice in this scenario.

Correct Answer: A

Rationale: A decrease in heart rate can indicate improved fluid balance and successful treatment of fluid volume deficit. When a client is experiencing fluid volume deficit, the heart rate typically increases as a compensatory mechanism to maintain cardiac output. As fluid volume is restored and the deficit is corrected, the heart rate should decrease back towards a normal range. Choices B, C, and D are less likely to be directly related to the successful treatment of fluid volume deficit. An increase in blood pressure may occur as a compensatory response to fluid volume deficit; a decrease in respiratory rate is not a typical indicator of fluid volume deficit correction; and an increase in urine output can be a sign of improved kidney function but may not directly reflect fluid volume status.

Correct Answer: A

Rationale: Monitoring hourly urine output is crucial after successful resuscitation from a pulseless dysrhythmia to assess kidney function and perfusion. The kidneys are particularly vulnerable to injury following cardiac events due to decreased perfusion during the event. Evaluating urine output hourly allows for early detection of renal impairment or inadequate organ perfusion. Option B, monitoring white blood cell count, is not a priority in this situation as it does not directly relate to immediate post-resuscitation care. Option C, checking blood glucose every 4 hours, is important but not as critical as assessing kidney function and perfusion. Option D, measuring temperature every 2 hours, is relevant for monitoring signs of infection or inflammatory response but is not as crucial as assessing kidney function in this scenario.

Correct Answer: B

Rationale: The correct way to transcribe the dosage of three tenths of a milligram of levothyroxine IV STAT is 0.3 mg. When expressing decimals less than 1, there should be a leading zero before the decimal point. Choice A is incorrect (.3 mg) because it lacks the leading zero. Choice C (0.30 mg) is incorrect as it includes a trailing zero after the decimal point, which is unnecessary. Choice D (3/10 mg) is incorrect as it presents the dosage as a fraction, which is not the standard format for transcribing medication dosages. Therefore, B (0.3 mg) is the most appropriate and accurate way to document this prescription on the client's medical record.
