A nurse is teaching a newly licensed nurse about the differences between a plaster cast and a synthetic cast. Which of the following information should the nurse include in the teaching?

"Drying time is prolonged with a synthetic cast."

"A synthetic cast is lighter."

"A plaster cast weighs less."

"Application of a plaster cast requires specialized equipment."

Answer and Explanation

The Correct Answer is B

Choice A reason: This statement is incorrect. Synthetic casts typically dry much faster than plaster casts. Plaster casts can take 24 to 48 hours to fully harden, while synthetic casts made from materials like fiberglass or plastic can harden within a few hours.

Choice B reason: This is the correct statement. Synthetic casts are indeed lighter than plaster casts. They are made from materials like fiberglass, which is lighter than the traditional plaster of Paris used in plaster casts.

Choice C reason: This statement is incorrect. Plaster casts are generally heavier than synthetic casts. The weight of a cast can be an important consideration, especially for children or for those who may have difficulty managing a heavier cast.

Choice D reason: This statement is incorrect. Both plaster and synthetic casts require specialized equipment for application, but it is not specific to plaster casts. The application involves similar steps for both types, including the use of a stockinette, padding, and then the casting material itself.

Correct Answer is C

Explanation

Choice A reason: Keeping the client NPO (nothing by mouth) is not directly related to preventing a thyroid crisis. While it may be necessary in some situations, such as preoperative care, it does not address the hyperthyroid state.

Choice B reason: Observing the client for signs of hypocalcemia is important, especially after thyroid surgery, as hypocalcemia can occur due to accidental removal or damage to the parathyroid glands. However, it is not a preventive measure for a thyroid crisis.

Choice C reason: Providing a quiet, low stimulus environment can help reduce stress and agitation, which are potential triggers for a thyroid crisis. Stress can exacerbate hyperthyroid symptoms and precipitate a crisis.

Choice D reason: Aspirin is contraindicated in clients with hyperthyroidism as it can increase thyroid hormone levels by displacing them from their binding proteins. This can potentially worsen the condition and lead to a crisis.

A. Metabolic Alkalosis, Partially Compensated. B. Respiratory Alkalosis, Uncompensated. C. Metabolic Alkalosis, Uncompensated. D. Respiratory Acidosis, Partially Compensated.

Correct Answer is B

Explanation

Choice A reason: This choice is incorrect. Metabolic alkalosis would be indicated by an elevated pH and HCO3, but the PaCO2 would typically be higher due to compensatory hypoventilation.

Choice B reason: This is the correct choice. The elevated pH and low PaCO2 indicate respiratory alkalosis, likely due to hyperventilation. The normal HCO3 suggests that there has been no renal compensation, hence 'uncompensated'.

Choice C reason: This choice is incorrect because, for metabolic alkalosis to be uncompensated, the PaCO2 would typically be normal or high, not low.

Choice D reason: This choice is incorrect. Respiratory acidosis would be indicated by a low pH and high PaCO2, which is not the case here.
