Correct Answer: A

Rationale: The correct answer is A: An IV line is inserted to provide access to a vein. In shock, adequate intravenous access is crucial to administer fluids and medications rapidly. This helps stabilize the client's condition by restoring blood volume and improving circulation. Choice B is incorrect as immobilization is not a primary intervention for shock in this scenario. Choice C, traction, is not appropriate for managing shock but rather for stabilizing spinal cord injuries. Choice D, using a turning frame, is not relevant to managing shock and does not address the immediate need for fluid resuscitation.

Correct Answer: D

Rationale: Correct Answer: D. Antagonize the action of K on the heart Rationale: 1. Calcium gluconate stabilizes cardiac cell membranes during hyperkalemia. 2. By antagonizing the effects of potassium on the heart, it helps prevent life-threatening cardiac arrhythmias. 3. It does not lower potassium levels immediately or prevent transient renal failure. 4. Administering calcium gluconate is specific to addressing the cardiac effects of hyperkalemia, not renal or overall potassium reduction.

Correct Answer: C

Rationale: Rationale: 1. Pulmonary edema is caused by increased hydrostatic pressure in the pulmonary circulation. 2. Elevated left ventricular end-diastolic pressure signifies heart failure, a common cause of pulmonary edema. 3. A rise in pulmonary venous pressure is a consequence of increased hydrostatic pressure. Therefore, all three alterations (A, B, D) are characteristic of pulmonary edema. Option C is correct. Choices A, B, and D are incorrect because they are all individually associated with pulmonary edema and collectively represent the condition.

Correct Answer: C

Rationale: Rationale: 1. Insulin is a hormone produced by beta cells of the pancreas. 2. Beta cells are responsible for monitoring blood glucose levels and secreting insulin in response to high glucose levels. 3. Insulin helps regulate blood glucose by facilitating glucose uptake into cells. 4. Adenohypophysis secretes other hormones, not insulin. 5. Alpha cells of the pancreas secrete glucagon, not insulin. 6. Parafollicular cells of the thyroid secrete calcitonin, not insulin. Summary: Choice C is correct because insulin is indeed secreted from the beta cells of the pancreas. Choices A, B, and D are incorrect as they do not secrete insulin or are related to other hormones.
