Correct Answer: B

Rationale: A case manager is the most appropriate interdisciplinary team member to consult for a client with anorexia nervosa. They can help coordinate care, resources, and communication between various healthcare professionals involved in the client's treatment. Consulting an occupational therapist (Choice A) may not directly address the primary concerns associated with anorexia nervosa. While nutritional therapists (Choice C) play a role in addressing nutritional needs, a case manager is better suited for overall care coordination. Mental health counselors (Choice D) focus more on emotional and psychological aspects, whereas a case manager coordinates practical aspects of care.

Correct Answer: D

Rationale: Most water leaves the body through the kidneys. The kidneys play a crucial role in filtering waste and excess substances from the blood to form urine, which is then excreted out of the body. Choices A, B, and C are incorrect because while a small amount of water can be lost through respiration, feces, and sweating, the primary organ responsible for regulating water balance and excretion is the kidneys.

Correct Answer: D

Rationale: Lactated Ringer's solution is the most suitable IV solution for a patient with hypovolemia. It is a balanced crystalloid solution containing electrolytes such as sodium, chloride, potassium, calcium, and lactate, which closely resemble the body's natural fluids. This solution helps to restore intravascular volume and electrolyte balance in hypovolemic patients. Choice A, 3% sodium chloride, is a hypertonic solution used for specific situations like severe hyponatremia or cerebral edema, not typically for hypovolemia. Choice B, 10% dextrose in water, is a hypertonic solution primarily used for providing calories and free water, not for volume expansion. Choice C, 0.45% sodium chloride, is a hypotonic solution used for conditions like hypernatremia or as maintenance fluid, not for hypovolemia.

Correct Answer: C

Rationale: The progressive stage of shock is accurately described as the stage where histamine is released, leading to fluid and proteins leaking into surrounding tissues and the blood thickening. In this stage, the body's compensatory mechanisms are overwhelmed, resulting in a cascade of events that worsen the shock state. Choice A is incorrect as hyperventilation and a rise in blood pH are more characteristic of the compensatory stage. Choice B is incorrect as hypoxia and a rise in lactic acid are more typical of the progressive stage. Choice D is incorrect as the described electrolyte imbalances and metabolic acidosis are more aligned with the refractory stage of shock.

Correct Answer: B

Rationale: The main purpose of quality improvement in healthcare is to improve patient outcomes by enhancing the quality and safety of healthcare services. Choice A is incorrect because the goal is not to increase healthcare costs but to optimize resources and provide cost-effective care. Choice C is incorrect as the aim is to increase patient satisfaction through better outcomes. Choice D is incorrect as the objective is to reduce hospital stays by improving care efficiency and effectiveness.
