ATI Pharmacology Final Exam 1 Questions

Question 1 of 5

The nurse recognizes that adrenergic drugs cause relaxation of the bronchi and bronchodilation by stimulating which type of receptors?

Correct Answer: B

Rationale: The correct answer is B: Beta2 adrenergic receptors. Adrenergic drugs cause bronchodilation by stimulating Beta2 adrenergic receptors in the bronchi. Activation of these receptors leads to smooth muscle relaxation and widening of the airways, improving airflow. Alpha 1 adrenergic receptors (
Choice
A) typically cause vasoconstriction, not bronchodilation. Beta adrenergic receptors (
Choice
C) are a broad category, but specifically, Beta2 receptors are responsible for bronchodilation. Dopaminergic receptors (
Choice
D) are not involved in bronchodilation.

Question 2 of 5

A client tells the nurse that he is having nausea and decreased appetite during drug therapy with a tetracycline antibiotic. Which statement is the nurse's best advice to the client?

Correct Answer: B

Rationale: The correct answer is B: Drink a full glass of water with each dose. Water helps prevent gastrointestinal irritation caused by tetracycline. Milk, cheese, and yogurt can bind to tetracycline and reduce its absorption, decreasing its effectiveness. Taking an antacid with tetracycline can also reduce its absorption.
Therefore, the best advice is to take it with water to avoid these interactions and ensure optimal drug absorption.

Question 3 of 5

An adrenergic agonist is ordered for a client in cardiogenic shock. The nurse will note that this drug has had its primary intended effect if which expected outcome occurs?

Correct Answer: A

Rationale: The correct answer is A: Increased cardiac output. Adrenergic agonists stimulate the sympathetic nervous system to increase heart rate and contractility, leading to improved cardiac output in cardiogenic shock. This helps improve tissue perfusion. Reduced anxiety (
B) and volume depletion (
C) are not primary effects of adrenergic agonists in this context. Decreased urine output (
D) may occur due to increased blood flow to vital organs, but it is not the primary intended effect in cardiogenic shock.

Question 4 of 5

The nurse is developing a care plan for a client who will be self-administering a metered-dose inhaler. Which statement reflects a measurable outcome?

Correct Answer: D

Rationale: The correct answer is D because it specifies a measurable outcome that can be observed and evaluated objectively. By demonstrating the proper technique of self-administering a metered-dose inhaler, the client's understanding and ability can be directly assessed.
Choice A is vague and subjective, as understanding may not necessarily translate to practical application.
Choice B only mentions knowledge without addressing application.
Choice C is similar to choice D but lacks the clarity of a specific action being demonstrated.

Question 5 of 5

A laxative has been ordered for a client. The nurse checks the client's medical history and would be concerned if which condition is present?

Correct Answer: C

Rationale: The correct answer is C: Abdominal pain of unknown origin. This is concerning because giving a laxative to a client with unknown abdominal pain can potentially worsen an underlying condition or cause complications. High ammonia levels (
A) are concerning but not directly related to the use of a laxative. Diverticulosis (
B) and chronic constipation (
D) are conditions that may actually benefit from a laxative, so they are not as concerning.
