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 A
Explanation
Choice A reason:
Offer to take pictures of the newborn for the client is the right choice, During the initial grieving process after experiencing a stillbirth, the nurse should offer to take pictures of the newborn for the client if the client wishes. Offering to take pictures is an essential and sensitive way to honour and validate the client's experience and the significance of their baby. It allows the client to have tangible memories of their child, which can be important for the grieving process and help in the healing journey.
It is crucial for the nurse to be supportive and compassionate during this time, respecting the client's emotional needs and preferences. Providing emotional support and empathy are critical components of caring for a client who has experienced the loss of a baby.
Choice B reason:
Assure the client that she can have additional children is not correct. While this statement may be well-intentioned, it may not be appropriate during the initial grieving process. The client may not be emotionally ready to discuss future pregnancies, and such assurances might minimize the significance of the loss they are experiencing. It is essential to be sensitive and refrain from making assumptions about the client's feelings or future plans.
Choice C reason:
Avoid talking to the client about the newborn. Avoiding talking to the client about the newborn may be seen as disregarding their feelings and emotions. Instead, it is essential to provide opportunities for the client to talk about their feelings and the baby if they wish to do so. Creating an environment where the client feels comfortable expressing their emotions can be crucial in the grieving process.
Choice D reason
Discouraging the client from allowing friends to see the newborn It is not appropriate for the nurse to discourage or prevent the client from allowing friends to see the newborn if they wish to do so. Grieving is a highly individual process, and some clients may find comfort and support in sharing their grief with loved ones. The nurse should respect the client's decisions regarding who they want to involve in their grieving process.
Correct Answer is B
Explanation
The correct answer is B.
Previous violent behavior. According to the web search results, this is the best predictor of future violence among the given risk factors.
Other risk factors include past history of aggression, poor impulse control, and violence. Comorbidity that leads to acts of violence (psychotic delusions, command hallucinations, violent angry reactions with cognitive disorders).
Choice A is wrong because a history of being in prison is not a direct cause of violence, but rather a possible consequence of it.
Choice C is wrong because male gender is not a sufficient factor to predict violence, as there are many other variables involved. Choice D is wrong because experiencing delusions is not necessarily associated with violence, unless they are of a paranoid or persecutory nature.
Normal ranges for violence risk assessment are not standardized, but some tools that can be used include the Historical Clinical Risk Management-20 (HCR-20), the Violence Risk Appraisal Guide (VRAG), and the Psychopathy Checklist-Revised (PCL-R). These tools use different scales and criteria to evaluate the likelihood of violent behavior in individuals.
