Answer to Question 1

2,4
Rationale 1: Functional antagonists do not block alpha receptors.
Rationale 2: Functional antagonists change pharmacokinetic factors such as excretion.
Rationale 3: Functional antagonists do not block beta receptors.
Rationale 4: Functional antagonists change pharmacokinetic factors such as metabolism.
Rationale 5: Drugs that bind with DNA may inhibit protein synthesis.
Global Rationale: Functional antagonists change pharmacokinetic factors such as excretion and metabolism. They do not block alpha or beta receptors. Drugs that bind with DNA may inhibit protein synthesis.

Answer to Question 2

1,2
Rationale 1: The most important question is if the patient has changed therapy secondary to test results.
Rationale 2: It is important for the patient to discuss the results of the tests and any indicated changes with the health care provider.
Rationale 3: Asking a why question is confrontational and is likely to result in the patient not sharing more information.
Rationale 4: The nurse may be curious as to the expense of the test, but the cost is not pertinent to this discussion.
Rationale 5: Asking who suggested the test is confrontational and is likely to result in the patient not sharing more information.
