Leadership and Management HESI

Correct Answer: B

Rationale: Managerial skills are crucial for nurse managers to be effective. They need to possess skills such as problem-solving and decision-making to handle various challenges in the healthcare setting. Clinical knowledge (choice A) is important for direct patient care but may not be the primary focus of a manager's role. Patient care coordination (choice C) is vital, but managerial skills are more directly related to a nurse manager's effectiveness. Human resource training (choice D) is helpful but not as essential as managerial skills in ensuring effective leadership in a nursing environment.

Correct Answer: B

Rationale: In hyperparathyroidism, there is an overproduction of parathyroid hormone, leading to increased calcium levels in the blood (hypercalcemia). This occurs as the parathyroid hormone stimulates the release of calcium from the bones and enhances calcium absorption in the intestines and kidneys. Therefore, the correct answer is hypercalcemia (Choice B). Hypocalcemia (Choice A) is not consistent with hyperparathyroidism, as this condition is characterized by high calcium levels. Hypokalemia (Choice C) and hyperphosphatemia (Choice D) are not typically associated with hyperparathyroidism and are not primary manifestations of this condition.

Correct Answer: C

Rationale: The correct answer is C because scientific management focuses on improving efficiency through the analysis of tasks and work processes. Choice A is more aligned with a human relations-based approach, which emphasizes motivation and relationships. Choice B reflects recognition and morale boosting, which is also characteristic of the human relations approach. Choice D involves conflict resolution and promoting mutual understanding, which is related to the human relations approach rather than scientific management.

Correct Answer: C

Rationale: In hypocalcemia, a decreased level of calcium can lead to a prolonged QT interval on the ECG due to its role in myocardial repolarization. A widened T wave (Choice A) is typically seen in hyperkalemia. A prominent U wave (Choice B) is associated with hypokalemia. A shortened ST segment (Choice D) is not a typical ECG finding in hypocalcemia.
