A nurse on a telemetry unit is assessing a client who is receiving continuous cardiac monitoring. The client's heart rate is 69/min and the PR interval is 0.24 seconds. The nurse should interpret this finding as which of the following cardiac rhythms?
Atrial fibrillation
First-degree AV block
Premature ventricular contraction
Sinus bradycardia
The Correct Answer is B
The correct answer is B.
Choice A reason: Atrial fibrillation is characterized by a rapid, irregular heartbeat and an absence of distinct P waves on the ECG, which is not indicated by the information provided.
Choice B reason: First-degree AV block is indicated by a prolonged PR interval without affecting the overall heart rate, aligning with the client’s PR interval of 0.24 seconds.
Choice C reason: Premature ventricular contraction would show an abnormal QRS complex on the ECG, which is not mentioned in the scenario.
Choice D reason: Sinus bradycardia is defined by a heart rate less than 60 bpm, which does not apply here as the client’s heart rate is 69/min, within the normal range of 60-100 bpm.

Correct Answer is C
Explanation
The correct answer is choice C. Perform a sterile dressing change for a client who has an abdominal wound. This is because a licensed practical nurse (LPN) can perform tasks that require technical skills and have predictable outcomes, such as dressing changes. A sterile dressing change is also within the scope of practice of an LPN.
Choice A is wrong because complete discharge teaching for a client who has a new diagnosis of diabetes mellitus requires assessment, evaluation and critical thinking, which are beyond the scope of practice of an LPN. Discharge teaching is the responsibility of a registered nurse (RN) who can provide education and counseling to clients and families.
Choice B is wrong because completing the Glasgow Coma Scale for a client who has an evolving stroke requires assessment and interpretation of neurological status, which are complex and unpredictable tasks that only an RN can perform. The Glasgow Coma Scale is a tool that measures the level of consciousness of a client based on eye opening, verbal response and motor response. A client who has an evolving stroke may have changes in their neurological status that require frequent monitoring and intervention by an RN.
Choice D is wrong because performing an admission assessment for a client who is scheduled for surgery requires comprehensive data collection, analysis and synthesis, which are advanced skills that only an RN can perform. An admission assessment involves obtaining a complete health history, performing a physical examination, identifying client needs and problems, and developing a plan of care.
A client who is scheduled for surgery may have complex and unpredictable needs that require specialized knowledge and judgment by an RN.
Correct Answer is B
Explanation
The correct answer is: B
Choice A reason: A social worker may assist clients in many ways, including finding legal representation. However, this statement does not address the client’s concern about the cost of legal representation for advance directives. It’s important to note that while social workers can provide support, they do not eliminate the need for legal representation if the client chooses to seek it.
Choice B reason: This is the correct statement because advance directives do not require legal representation to be valid. They become legally binding when signed in front of the required witnesses. This option directly addresses the client’s concern about affording legal representation by informing them that it is not necessary for the creation of advance directives.
Choice C reason: While medical care can be initiated without advance directives, this statement does not address the client’s concern about the cost of creating advance directives. It also implies that medical care is contingent on the completion of legal documents, which is not accurate.
Choice D reason: Verbal agreements are not as legally binding as written advance directives and could lead to misunderstandings or disputes later on. It is important for the client to have a clear and documented advance directive, which does not necessarily require legal review to be valid.
