A healthcare professional reviews a client's electrolyte laboratory report and notes that the potassium level is 3.2 mEq/L. Which of the following would the healthcare professional note on the electrocardiogram as a result of the laboratory value?

Correct Answer: A

Rationale: The correct answer is A: U waves. A low potassium level (hypokalemia) can manifest as U waves on an ECG. U waves are small, extra deflections seen after the T wave and may indicate cardiac irritability. Absent P waves (Choice B) are associated with conditions like atrial fibrillation. Elevated T waves (Choice C) can be seen in hyperkalemia, not hypokalemia. Elevated ST segment (Choice D) is not typically associated with low potassium levels but can be seen in conditions like myocardial infarction.

Correct Answer: D

Rationale: Clients who have sustained traumatic burns are at a higher risk of developing hyperkalemia due to cell lysis. When cells are damaged in a traumatic burn, potassium can leak out from the intracellular space into the bloodstream, leading to elevated serum potassium levels. Colitis, Cushing's syndrome, and overuse of laxatives are not typically associated with the same degree of cell damage or potassium shifts seen in traumatic burns, making them less likely to result in such high potassium levels.

Correct Answer: A

Rationale: The best method for communicating a vision for the future is to involve others in creating the vision and connect daily work tasks to the vision. This approach fosters ownership and commitment among team members, as they feel part of the vision-building process and understand how their daily tasks contribute to achieving that vision. Choice B, encouraging staff nurses to openly discuss practice and possible improvements, is important for fostering communication but doesn't directly address creating and communicating a vision. Choice C, critically analyzing and discussing advances in practice with other nurses, focuses on professional development and knowledge sharing rather than specifically communicating a future vision. Choice D, actively listening to recommendations, is valuable for gathering input but may not be sufficient on its own for effectively communicating a future vision.

Correct Answer: B

Rationale: The best way for a follower to 'manage up' is by assisting the manager in capitalizing on his or her strengths and weaknesses. By doing so, the follower helps build a good working relationship with the manager, fostering mutual growth and development. Choice A is not the best option as it only focuses on providing feedback when asked, which may not necessarily contribute to 'managing up.' Choice C is incorrect because transferring to a different unit should not be the first solution when dealing with a manager with poor leadership skills; instead, efforts should be made to improve the current working relationship. Choice D, while important, focuses more on showing respect and appreciation rather than actively helping the manager improve, which is key to 'managing up.'

Correct Answer: B

Rationale: The correct answer is 'Business sense.' Nurse managers need to understand how financial decisions impact patient outcomes, which requires a strong understanding of business principles. Leadership (choice A) is important but doesn't specifically address understanding financial and outcome-based impacts. Clinical expertise (choice C) is essential for patient care but doesn't directly relate to understanding budget changes and their impact. Financial management (choice D) is more about managing finances directly rather than understanding the broader implications of budget changes on patient outcomes.
