Correct Answer: D

Rationale: The correct answer is D. In functional structures, employees are grouped in departments by specialty, with similar tasks being performed by the same group. This means that in a healthcare system with a functional structure, all nursing tasks would fall under the nursing service.

Choices A, B, and C are incorrect because open communication between departments, one department having authority over another, or the level of authority of a particular department do not necessarily represent a functional structure.

Correct Answer: B

Rationale: The correct answer is B because choosing a puncture site in the center of the finger pad is not recommended for blood glucose monitoring. The recommended sites are the sides of the fingertips. Option A is correct as washing the puncture site using warm water and soap is a good practice. Option C is also correct as hanging the arm down for a minute can help increase blood flow. Option D is incorrect as a blood sugar level of 120 mg/dL may not necessarily indicate good blood sugar control and needs further interpretation.

Correct Answer: D

Rationale: Job satisfaction is a crucial factor in sustaining employee satisfaction. Studies have shown that higher levels of job satisfaction lead to lower turnover rates and higher productivity.
Choice A, organization culture, is important but focuses more on the overall environment rather than individual satisfaction.
Choice B, individual performance, is relevant but doesn't directly address employee satisfaction.
Choice C, performance evaluation, is a process rather than a factor in sustaining satisfaction.

Correct Answer: D

Rationale: A sodium level of 125 mEq/L indicates hyponatremia, which can lead to abdominal cramping. Abdominal cramping is a common symptom of hyponatremia due to an imbalance in electrolytes. While other options like Chvostek's sign, bradycardia, and numbness of the extremities can be associated with other electrolyte imbalances, they are not typically seen with low sodium levels. Chvostek's sign is related to hypocalcemia, bradycardia can be seen in hyperkalemia, and numbness of the extremities can be a symptom of hypocalcemia or hypokalemia, but not directly related to hyponatremia.

Correct Answer: C

Rationale: When a client is experiencing difficulty breathing, the priority intervention is to assist the client to an upright position. This position helps improve ventilation by maximizing lung expansion and promoting better oxygenation. Suctioning the airway may be necessary if there is an obstruction, but repositioning the client is the initial step. Instructing the client to perform incentive spirometry and humidifying oxygen are important interventions but not the first priority in this scenario.
