A nurse recognizes the class of medication being administered to help plan ongoing assessment and client education. The nurse would identify which drug as an example of a b-adrenergic blocker?
- A. Carvedilol (Coreg)
- B. Propranolol (Inderal)
- C. Metoprolol (Lopressor)
- D. Atenolol (Tenormin)
- E. Labetalol (Trandate)
Correct Answer: B,C,D
Rationale: Propranolol, metoprolol, and atenolol are b-adrenergic blockers, but carvedilol and labetalol are a/b-adrenergic blockers.

A nurse is caring for a client who has been prescribed propranolol for angina. After administering the drug, which of the following would the nurse do?
- A. Ask about relief of symptoms and record responses on the chart
- B. Determine signs of infection in the client
- C. Monitor for sudden decrease in urine output
- D. Monitor for sudden increase in intraocular pressure
Correct Answer: A
Rationale: The nurse should ask about the relief of symptoms and record the responses on the client's chart. Determining the signs of infection in the client is part of the nurse's preadministration assessment, not the ongoing assessment. The nurse need not monitor the client for a sudden decrease in urine output and a sudden increase in intraocular pressure for a client receiving propranolol therapy for angina.
A nurse understands that while most b-adrenergic receptors are found in the heart, they are also commonly found in which other organs?
- A. Pancreas
- B. Eyes
- C. Liver
- D. Lungs
- E. Skin
Correct Answer: B,D
Rationale: b-adrenergic receptors are also found in the eyes and lungs. The blockage of these receptors can be beneficial in treatment of glaucoma or cause adverse reactions in the lungs (bronchospasms).
A client with a cardiac problem is treated with b-adrenergic blocking drugs. Which of the following should the nurse identify as a cardiac reaction that impacts the body when a b-adrenergic blocking drug is given to the client?
- A. Vomiting
- B. Hyperglycemia
- C. Nausea
- D. Vertigo
Correct Answer: D
Rationale: The nurse should identify vertigo as the cardiac reaction that impacts the body when a b-adrenergic blocking drug is given to the client. Vomiting, nausea, and hyperglycemia are not cardiac reactions; they are gastrointestinal reactions that are observed when the client is administered b-adrenergic blocking drugs.
A nurse is preparing to administer a centrally acting adrenergic blocker to a group of clients. The nurse would be especially cautious when administering the drug to which client?
- A. Client with diabetes
- B. Client with chronic bronchitis
- C. Client with renal function impairment
- D. Client with impaired hepatic function
Correct Answer: C
Rationale: The nurse should administer centrally acting adrenergic blockers cautiously to clients with renal function impairment. The a/b-adrenergic blocking drugs should be used cautiously in clients with diabetes, chronic bronchitis, and impaired hepatic function.
A client is receiving nadolol as part of the treatment plan for hypertension. The client reports dizziness on standing. The nurse checks the client's blood pressure lying, sitting, and standing and notes a significant drop in the readings. When developing this client's plan of care, which nursing diagnosis would the nurse most likely identify?
- A. Risk for Injury
- B. Ineffective Tissue Perfusion
- C. Impaired Comfort
- D. Decreased Cardiac Output
Correct Answer: A
Rationale: The client is experiencing orthostatic hypotension, placing the client at risk for falls and injury. Ineffective Tissue Perfusion would be appropriate if the client was experiencing more rapid changes in blood pressure and/or changes in pulse and heart rate. Impaired Comfort would apply if the client was complaining of other adverse reactions such as dry mouth or constipation. There is no information provided that would suggest decreased cardiac output.
