Correct Answer: C

Rationale: The correct nursing intervention for a male client with SIADH is to restrict fluids. In SIADH, there is excess release of antidiuretic hormone (ADH), leading to water retention and dilutional hyponatremia. Restricting fluids helps prevent further dilutional hyponatremia by reducing water intake. Infusing I.V. fluids rapidly (choice A) would worsen the condition by adding more fluids, encouraging increased oral intake (choice B) is contraindicated as it adds more fluids, and administering glucose-containing I.V. fluids (choice D) is not a standard treatment for SIADH.

Correct Answer: D

Rationale: To improve retention of newly hired nurses, the nurse manager should focus on building their own leadership skills and relationships with staff members. By creating a supportive environment and demonstrating effective leadership, the manager can positively impact staff retention. Options A, B, and C do not directly address the core issue of creating a supportive work environment and effective leadership, which are crucial for retaining newly hired nurses.

Correct Answer: C

Rationale: Clients with hyperparathyroidism should avoid high-calcium foods like milk because they already have elevated calcium levels. Bananas and spinach are not high in calcium and can be included in the diet. Processed meats are not specifically contraindicated in hyperparathyroidism, so they are not the correct answer.

Correct Answer: C

Rationale: A magnesium level of 1.0 mg/dL can cause a depressed ST segment on the ECG. Magnesium deficiency commonly leads to ST segment depression on an electrocardiogram. Prominent U waves are associated with hypokalemia, prolonged PR interval is seen in conditions like first-degree heart block, and widened QRS complexes are typically related to conditions affecting the conduction system of the heart, such as bundle branch blocks.

Correct Answer: A

Rationale: The nurse manager's role in managing conflict involves identifying the sources of conflict and working with staff members to resolve them in a constructive manner. This includes addressing conflicts at their root cause and guiding staff towards effective resolution. Choice B is incorrect as the nurse manager typically does not act as a mediator but rather empowers staff to resolve conflicts themselves. Choice C is incorrect as while facilitating communication is important, it is not the sole responsibility of the nurse manager. Choice D is incorrect as providing training and support for conflict management is part of the role, but the primary responsibility lies in addressing the sources of conflict directly.
