Correct Answer: B

Rationale: The correct answer is B. Immediate evaluation by the surgeon is necessary due to the possibility of an internal hemorrhage, which is a life-threatening condition. Choice A is incorrect as lung status and oxygen saturation are not the priority in this situation. Choice C is not relevant to the current urgent issue. Choice D, while providing additional history, is not pertinent to the immediate concern of a potential internal hemorrhage post angioplasty and stent placement.

Correct Answer: D

Rationale: The best client for the charge nurse to assign to a practical nurse (PN) is an older client post-stroke who is aphasic with right-sided hemiplegia. This client is stable and suitable for care by a PN under supervision. Choices A, B, and C present clients with more complex and acute conditions that would require a higher level of nursing expertise and intervention.

Correct Answer: D

Rationale: Assessing fundal tone and lochia flow is crucial in the immediate postpartum period to detect postpartum hemorrhage, a life-threatening complication. Monitoring these parameters allows for early identification of excessive bleeding, enabling prompt intervention. While maintaining cold packs to the perineum, assessing pain levels, and observing for appropriate interaction with the infant are important aspects of postpartum care, assessing fundal tone and lochia flow takes precedence due to its direct relevance to identifying and managing a potential emergency situation.

Correct Answer: C

Rationale: The correct answer is C: Peaked T waves on the ECG. In hyperkalemia, elevated potassium levels can affect the heart's electrical activity, leading to changes on the ECG such as peaked T waves. This finding is concerning as it can progress to serious cardiac arrhythmias, including ventricular tachycardia and fibrillation. Bradycardia (choice A) and decreased deep tendon reflexes (choice D) are not typically associated with hyperkalemia. While muscle weakness (choice B) can occur in hyperkalemia due to its effect on neuromuscular function, the most concerning assessment finding indicating the need for immediate intervention in this scenario is peaked T waves on the ECG.

Correct Answer: D

Rationale: In a client with increased intracranial pressure (ICP), the body's compensatory mechanisms lead to an elevation in blood pressure and a widening pulse pressure. This occurs due to the body's attempt to maintain cerebral perfusion. Therefore, elevated blood pressure and widening pulse pressure are classic signs of increased ICP and necessitate immediate attention. Choices A, B, and C are incorrect because a widening pulse pressure, sudden drop in heart rate, or decreased urine output are not specific indicators of increased ICP.
