A client with a history of myocardial infarction (MI) is receiving a beta-blocker medication. What is the most important outcome for the nurse to monitor?

Correct Answer: A

Rationale: The correct answer is A: Heart rate and blood pressure. When a client with a history of myocardial infarction (MI) is on a beta-blocker medication, monitoring heart rate and blood pressure is crucial. Beta-blockers lower heart rate and blood pressure, so monitoring these parameters helps assess the medication's effectiveness and prevent complications like bradycardia or hypotension. Choices B, C, and D are not the most important outcomes to monitor in this scenario. Blood glucose levels are typically monitored in clients with diabetes or when using medications that affect glucose levels. Respiratory rate is important in assessing respiratory function and oxygenation, while liver function tests are more relevant when monitoring the impact of medications on liver health.

Correct Answer: B

Rationale: The correct answer is B: 'The technique is intended to maintain straight spinal alignment.' Log-rolling is a technique used to move a person as a single unit to maintain the alignment of the spinal column. This is crucial to prevent spinal cord injury, especially in clients with suspected spine fractures. Choice A is incorrect because log-rolling focuses on spinal alignment, not just decreasing back injury risks. Choice C is incorrect because the number of people involved is not the primary purpose of log-rolling, which is maintaining spinal alignment. Choice D is incorrect because while turning instead of pulling may help prevent skin damage, the primary goal of log-rolling is to protect the spine, not the skin.

Correct Answer: A

Rationale: The correct position for a child with a nosebleed (epistaxis) is sitting up and leaning forward. This position helps prevent blood from flowing into the throat and causing choking. Choice B, reclining with the head elevated, and choice D, lying flat on the back, are incorrect as they can cause blood to flow backward into the throat. Choice C, sitting up with the head tilted back, is also incorrect as it can lead to blood flowing down the back of the throat and potentially into the airway.

Correct Answer: C

Rationale: The correct answer is C because it provides a truthful yet sensitive response to the child's question. Saying that the body will stop functioning and that there will be no more pain helps the child understand what to expect without unnecessary details or causing distress. Choice A is too technical and may not be suitable for a child. Choice B might give the impression of a peaceful passing, which may not always be the case. Choice D introduces the concept of feeling tired, which might not be accurate or helpful in this context.

Correct Answer: C

Rationale: Turning the client to the right lateral position is essential as it can improve fetal oxygenation and uterine blood flow, promoting better labor outcomes. This intervention helps relieve pressure on blood vessels, enhancing blood flow to the placenta and improving oxygen supply to the fetus. Applying oxygen at a specific rate may not address the underlying issue of compromised blood flow and oxygenation. Stopping the oxytocin infusion is not the priority unless medically indicated as it can affect labor progression. While monitoring the progress of labor is important, actively addressing the compromised fetal oxygenation and uterine blood flow by changing the client's position takes precedence in this scenario.
