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 A

Explanation

Choice A reason: This set of values is indicative of metabolic acidosis with respiratory compensation, which is common in chronic kidney disease due to the accumulation of acids in the blood and the lungs' attempt to compensate by retaining CO2.

Choice B reason: This choice suggests respiratory alkalosis, which is less likely in chronic kidney disease unless there is a secondary respiratory condition causing hyperventilation.

Choice C reason: This choice indicates metabolic alkalosis, which is not typical for chronic kidney disease, as the kidneys are unable to excrete acid effectively.

Choice D reason: While this set of values does indicate acidosis, the expected compensatory response in chronic kidney disease would be an elevated PaCO2, not a normal or low value.

A. The test measures the hormone that attaches to a protein in your blood. B. The test measures the hormone that feeds the thyroid gland. C. The test measures the hormone that indicates the metabolic rate. D. The test measures the hormone that controls energy levels.

Correct Answer is C

Explanation

Choice A reason: The statement is incorrect because TSH does not attach to a protein in the blood; it stimulates the thyroid gland to produce thyroid hormones.

Choice B reason: This choice is partially correct. TSH does stimulate the thyroid gland, but the main purpose of the test is not to measure the 'feeding' of the gland but to assess its function and how well it's producing thyroid hormones.

Choice C reason: This is the correct statement. TSH levels are measured to determine the thyroid gland's activity, which directly influences the metabolic rate. The normal range for TSH levels in adults is typically 0.4 to 4.0 milliunits per liter (mU/L). However, these values can vary slightly based on the laboratory and the age of the individual.

Choice D reason: While TSH does influence energy levels by regulating thyroid hormone production, this choice does not directly explain the purpose of measuring TSH levels.
