ace inhibitors

ATI RN

ATI Proctored Pharmacology Test

1. How do ACE inhibitors work?

A. Block the vasoconstrictor and aldosterone effects of angiotensin II at the receptor site
B. Block stimulation of beta 1 and beta 2 at the receptor sites
C. Block the conversion of angiotensin I to the vasoconstrictor angiotensin II
D. None of the above

Correct answer: C

Rationale: ACE inhibitors work by inhibiting the conversion of angiotensin I to angiotensin II. Angiotensin II is a potent vasoconstrictor, and by blocking its production, ACE inhibitors help dilate blood vessels, reduce blood pressure, and decrease the workload of the heart. Choice A is incorrect because it describes the mechanism of action of angiotensin receptor blockers (ARBs), not ACE inhibitors. Choice B is incorrect as it describes beta-blockers, not ACE inhibitors. Choice D is incorrect as ACE inhibitors do have a specific mechanism of action.

2. A client with active pulmonary tuberculosis (TB) is to be started on intravenous rifampin therapy. The client should be informed by the nurse that this medication can cause which of the following adverse effects?

A. Constipation
B. Black-colored stools
C. Staining of teeth
D. Body secretions turning a red-orange color

Correct answer: D

Rationale: The correct answer is D: Body secretions turning a red-orange color. Rifampin is known to cause body secretions, such as urine, sweat, tears, and sputum, to turn a harmless red-orange color. This is a common and expected side effect of rifampin therapy. Choices A, B, and C are incorrect. Constipation is not a common adverse effect of rifampin. Black-colored stools and staining of teeth are not associated with rifampin therapy. It is important for the nurse to educate the client about the harmless red-orange discoloration that may occur with this medication.

3. Which of the following is not a known effect of the drug Clozapine?

A. Agranulocytosis
B. Antipsychotic
C. Used for Schizophrenia
D. Hyperactivity

Correct answer: D

Rationale: Clozapine is associated with side effects like agranulocytosis (a serious blood condition), sedation (not hyperactivity), and is used as an antipsychotic to treat schizophrenia. Hyperactivity is not a typical effect of Clozapine, making it the correct answer in this context.

4. When assessing a client with chronic Neutropenia receiving Filgrastim, what action should the nurse take to evaluate for an adverse effect of the medication?

A. Assess for bone pain.
B. Assess for right lower quadrant pain.
C. Auscultate for crackles in the bases of the lungs.
D. Auscultate the chest to listen for a heart murmur.

Correct answer: A

Rationale: The correct action when assessing a client receiving Filgrastim for chronic Neutropenia is to assess for bone pain. Bone pain is a known dose-related adverse effect of Filgrastim. Acetaminophen or opioid analgesics can be used to manage bone pain if necessary. Assessing for other types of pain, lung crackles, or heart murmurs would not be specific to the adverse effects of Filgrastim.

5. A client is receiving imatinib. Which of the following adverse effects should the nurse monitor?

A. Edema
B. Constipation
C. Dry mouth
D. Urinary retention

Correct answer: A

Rationale: Corrected Rationale: Imatinib is known to cause edema as an adverse effect. The nurse should closely monitor the client for signs of fluid retention, such as swelling of the extremities or weight gain. Edema can indicate potential complications and requires prompt intervention to prevent further issues. Choices B, C, and D are incorrect because they are not typically associated with imatinib use. Constipation, dry mouth, and urinary retention are not commonly reported adverse effects of imatinib therapy.
