Correct Answer: D

Rationale: When documenting information in a client's medical record, the nurse should end each entry with their signature and title. This practice is crucial for legal and professional standards compliance as it ensures that the documentation is attributable to the responsible individual. Choices A, B, and C are incorrect because while crossing out errors, using a black ink pen, and leaving a blank line before each entry are good practices, they are not as critical as ensuring each entry is signed and titled by the nurse for accountability and traceability.

Correct Answer: B

Rationale: Providing a diversionary activity is the most appropriate nursing intervention to promote comfort for a client with pericarditis. This intervention helps to distract the patient and reduce discomfort by focusing their attention elsewhere. Auscultating heart sounds, while important for monitoring the condition, does not directly address the client's comfort. Encouraging deep breathing can be beneficial for some conditions but may not be specifically aimed at promoting comfort in pericarditis. Maintaining a patent intravenous access is essential for treatment access and management of the condition, but it does not directly promote comfort for the client.

Correct Answer: A

Rationale: The correct order in the nursing process is Assessment, Diagnosis, Planning, Implementation, and Evaluation. Assessment involves gathering information about the patient, Diagnosis is identifying the problem, Planning involves setting goals and outcomes, Implementation is carrying out the plan, and Evaluation is assessing the outcomes. Choices B, C, and D have the steps in the incorrect order, not following the standard nursing process framework. Therefore, the correct answer is option A.

Correct Answer: B

Rationale: The correct answer is B: Airborne isolation. Measles is highly contagious and can be transmitted through airborne particles, so airborne isolation is necessary to prevent its spread. Choice A, Contact isolation, is incorrect because measles is not primarily transmitted through direct contact. Choice C, Droplet isolation, is also incorrect as measles is not transmitted through large droplets but through smaller airborne particles. Choice D, Reverse isolation, is used to protect a patient from outside infections, not to prevent the spread of a contagious disease like measles.

Correct Answer: B

Rationale: A heart rate of 120 beats per minute is within the normal range for a 2-month-old infant. Therefore, it is safe to administer the digoxin and document the heart rate as part of routine care. Choice A is incorrect as withholding the medication is not necessary since the heart rate is normal. Choice C is incorrect as there is no need to delay the administration until the next scheduled dose when the heart rate is within the normal range. Choice D is incorrect as the primary nurse is not needed to administer the medication since the heart rate is normal and falls within the safe range for administration.
