A nurse is reinforcing teaching with a client who is scheduled for a cardiac catheterization. Which of the following should the nurse tell the client to expect during injection of the contrast medium?

The correct answer is c. Apply a moist saline dressing to the area.

Choice A reason: Obtaining a set of vital signs is important, but it is not the immediate priority in this situation. The vital signs will not address the protruding organs directly.

Choice B reason: Flexing the client’s knees and hips may provide comfort but does not directly address the issue of the open incision and protruding organs.

Choice C reason: Applying a moist saline dressing to the area is the correct action. It helps to protect the protruding organs by keeping them moist and reduces the risk of organ damage or infection. This is the priority action to keep the organs moist and reduce the risk of tissue damage until surgical repair can be done.

Choice D reason: Elevating the head of the client’s bed 20° may be part of the overall care plan, but it is not the immediate priority when dealing with protruding organs from an open abdominal incision.

The correct answer is choice B: Store opened insulin vials at room temperature for up to 4 weeks.

Choice B rationale: Opened insulin vials can be stored at room temperature (59°F to 86°F or 15°C to 30°C) for up to 4 weeks. After this period, the insulin may lose potency, and a new vial should be used.

Choice A rationale: Regular insulin is short-acting, and its peak effect occurs 2 to 3 hours after administration. Eating a snack 6 hours after insulin administration may not be necessary as the insulin would have already reached its peak effect, and blood glucose levels should be monitored accordingly.

Choice C rationale: Warming the insulin vial to dissolve crystals is not recommended. Insulin should be inspected before use, and if crystals or clumps are present, it should be discarded as this could indicate that the insulin has lost its effectiveness.

Choice D rationale: Unopened insulin vials should be stored in the refrigerator (36°F to 46°F or 2°C to 8°C) and should not be frozen. Freezing can cause insulin to lose potency or become ineffective. Once opened, insulin vials can be stored at room temperature for up to 4 weeks, as mentioned in choice B.
