Correct Answer: B

Rationale: In this scenario, it is more appropriate to assign a stable client, such as the one with a myocardial infarction who is free from pain and dysrhythmias, to a nurse who lacks specialized critical care experience. This client's condition is relatively stable and does not require immediate critical interventions. Choices A, C, and D involve clients with more complex and critical conditions that would be better managed by a nurse with specialized critical care training. Choice A involves a client on a Dopamine drip with frequent vital sign monitoring, Choice C has a client with a tracheotomy in respiratory distress, and Choice D describes a client with a pacemaker experiencing intermittent capture, all of which require a higher level of critical care expertise.

Correct Answer: D

Rationale: In a client experiencing a sudden drop in blood pressure after epidural anesthesia, the first action the nurse should take is to place the client in a lateral position. This position helps improve venous return and cardiac output by relieving aortocaval compression. Administering oxygen via nasal cannula may be necessary if the client shows signs of respiratory distress, but it is not the first priority in this situation. Administering an intravenous fluid bolus can help stabilize blood pressure, but repositioning the client takes precedence. Preparing the client for an emergency cesarean section is not indicated solely based on a sudden drop in blood pressure after epidural anesthesia; this step would be considered if other complications arise.

Correct Answer: B

Rationale: Offering frequent snacks of foods the client enjoys is the most appropriate action to enhance the nutritional intake of a client with Alzheimer's disease. This approach helps to ensure that the client receives an adequate amount of nutrients throughout the day, especially when larger meals might be challenging for individuals with Alzheimer's. Encouraging large meals in one sitting (Choice A) may overwhelm the client and lead to decreased food intake. While foods high in fiber (Choice C) are beneficial for digestion, the primary focus should be on providing foods the client enjoys to increase intake. Discouraging eating late at night (Choice D) is not directly related to enhancing nutritional intake in this scenario.

Correct Answer: B

Rationale: An S3 heart sound is often a normal finding in pregnant women due to increased blood volume and cardiac output. The nurse should document the finding as part of the routine assessment unless accompanied by other abnormal symptoms. Performing a 12-lead electrocardiogram (Choice A) is unnecessary for a normal S3 heart sound in pregnancy. Notifying the healthcare provider immediately (Choice C) is premature and may lead to unnecessary interventions. Assessing for signs of heart failure (Choice D) is not indicated as an isolated S3 heart sound is typically benign in pregnancy.

Correct Answer: A

Rationale: The correct answer is to monitor the client's potassium level. During hemodialysis, there is a risk of potassium shifting, which can lead to life-threatening arrhythmias if not properly managed. Assessing the potassium level is crucial to prevent complications. While assessing blood pressure, checking hemoglobin and hematocrit levels, and monitoring for signs of infection are important aspects of care for a client with chronic kidney disease, monitoring potassium levels takes precedence due to its immediate life-threatening potential post-dialysis.
