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?
- A. U waves
- B. Absent P waves
- C. Elevated T waves
- D. Elevated ST segment
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.

A female client with a history of pheochromocytoma is admitted to the hospital in an acute hypertensive crisis. To reverse the hypertensive crisis caused by pheochromocytoma, nurse Lyka expects to administer:
- A. Phentolamine (Regitine)
- B. Methyldopa (Aldomet)
- C. Mannitol (Osmitrol)
- D. Felodipine (Plendil)
Correct Answer: A
Rationale: In a hypertensive crisis due to pheochromocytoma, the appropriate medication to administer is Phentolamine (Regitine), an alpha-adrenergic blocker. Phentolamine acts quickly to block the effects of excess catecholamines that are released in pheochromocytoma, helping to rapidly lower blood pressure. Methyldopa (Aldomet) is an alpha-2 adrenergic agonist used for chronic hypertension, not for acute crises like pheochromocytoma. Mannitol (Osmitrol) is an osmotic diuretic used to reduce intracranial pressure and treat cerebral edema, not indicated for hypertensive crises. Felodipine (Plendil) is a calcium channel blocker used for chronic management of hypertension, not for acute hypertensive crises like those seen in pheochromocytoma.
Which of the following best describes the nurse's responsibility in obtaining informed consent?
- A. The nurse is responsible for ensuring that the patient understands the procedure and has the opportunity to ask questions.
- B. The nurse should ensure that the patient signs the consent form before the procedure begins.
- C. The nurse is responsible for witnessing the patient sign the consent form and documenting the event.
- D. The nurse should delegate the task of obtaining informed consent to another healthcare provider.
Correct Answer: A
Rationale: The correct answer is A. Informed consent is a process where the healthcare provider, in this case, the nurse, ensures that the patient understands the procedure, risks, benefits, and alternatives before they agree to it. The nurse plays a crucial role in facilitating this understanding by explaining the information in a clear and understandable manner and providing the patient with the opportunity to ask questions. Choice B is incorrect because merely obtaining the patient's signature on the consent form does not ensure that the patient truly understands what they are consenting to. Choice C is not fully accurate as the nurse's role goes beyond just witnessing the signature; it involves actively ensuring the patient's comprehension. Choice D is incorrect as the responsibility of obtaining informed consent should not be delegated to another healthcare provider, as it is the nurse's duty to ensure proper communication and understanding with the patient.
The client is receiving dietary instructions for hypoparathyroidism. Which of the following dietary recommendations is appropriate?
- A. Increase intake of dairy products and green leafy vegetables
- B. Avoid foods high in calcium
- C. Consume a high-sodium diet
- D. Limit fluid intake to prevent fluid overload
Correct Answer: A
Rationale: For clients with hypoparathyroidism, the appropriate dietary recommendation is to increase intake of calcium-rich foods like dairy products and green leafy vegetables to help manage hypocalcemia. This is because hypoparathyroidism leads to low levels of calcium in the blood, so increasing calcium intake through diet is essential. Choices B, C, and D are incorrect. Avoiding foods high in calcium (choice B) would exacerbate the hypocalcemia. Consuming a high-sodium diet (choice C) is not necessary for managing hypoparathyroidism. Limiting fluid intake (choice D) is not directly related to the dietary management of hypoparathyroidism.
A nurse manager is working to improve patient satisfaction on the unit. Which of the following best describes the nurse manager's role in this process?
- A. The nurse manager should set clear expectations for patient satisfaction, monitor progress, and provide feedback to staff members to continuously improve patient care.
- B. The nurse manager should gather data on patient satisfaction, identify areas for improvement, and implement strategies to enhance the patient experience.
- C. The nurse manager should develop a patient satisfaction improvement plan, set measurable goals, and track progress over time to ensure continuous improvement.
- D. The nurse manager should involve patients and families in the patient satisfaction improvement process, gather feedback, and use it to make improvements to care delivery.
Correct Answer: A
Rationale: The correct answer is A. The nurse manager's role in improving patient satisfaction involves setting clear expectations for patient satisfaction, monitoring progress, and providing feedback to staff members to continuously improve patient care. Choice B is incorrect as gathering data and implementing strategies are typically part of quality improvement initiatives but do not solely define the nurse manager's role. Choice C is incorrect because the nurse manager is responsible for setting expectations and monitoring progress rather than developing the improvement plan. Choice D is incorrect as involving patients and families and gathering feedback are important aspects, but the question specifically asks about the nurse manager's role, which primarily involves setting expectations, monitoring progress, and providing feedback to staff.
What is the nurse manager's role in improving the quality of care on the unit?
- A. The nurse manager is responsible for setting goals and priorities for the unit and ensuring that staff members are working towards achieving those goals.
- B. The nurse manager is responsible for monitoring patient outcomes and implementing changes to improve the quality of care on the unit.
- C. The nurse manager is responsible for ensuring that staff members follow established procedures and protocols to maintain the quality of care on the unit.
- D. The nurse manager is responsible for providing feedback and coaching to staff members to help them improve their performance and achieve the unit's quality goals.
Correct Answer: A
Rationale: The nurse manager plays a crucial role in improving the quality of care on the unit by setting goals and priorities for the unit and ensuring that staff members are working towards achieving those goals. This involves strategic planning, coordination, and leadership to guide the team in delivering high-quality patient care. Option B is incorrect as while monitoring patient outcomes is important, it is not the primary role of the nurse manager in improving care quality. Option C is incorrect because while ensuring staff adherence to procedures is important, it is a part of maintaining quality rather than actively improving it. Option D is incorrect as providing feedback and coaching, though essential, is not the primary role of the nurse manager in setting goals and priorities for quality improvement.
