Question 1 of 5
Which of the following is not a phenylpropionic derivatives:
Correct Answer: D
Rationale: Mefenamic acid is not a phenylpropionic derivative. It is classified as a fenamate, structurally related to fenamic acid. The other options (A. ibuprofen, B. fenoprofen, C. naproxen) are all examples of phenylpropionic derivatives, commonly referred to as propionic acids. These drugs have similar chemical structures and mechanisms of action, making them a distinct group within the nonsteroidal anti-inflammatory drug (NSAID) class.
Question 2 of 5
In what patient is propranolol (Inderal) contraindicated?
Correct Answer: B
Rationale: Beta-adrenergic blocking agents are contraindicated in patients with bradycardia, heart failure, and heart block. The drug would not be contraindicated in the other patients. The nurse should assess the patient’s medical history and contraindications before administering propranolol to ensure safe and effective treatment.

Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 5
A nurse is providing instructions to a client receiving baclofen (Lioresal). Which of the following would be included in the teaching plan?
Correct Answer: D
Rationale: Baclofen is a muscle relaxant used to treat spasticity. Weakness is a potential side effect and should be reported to the physician, as it may indicate an adverse reaction or the need for dose adjustment. Limiting fluid intake is not typically recommended, and holding the medication due to diarrhea is not a standard instruction. While alcohol can enhance the sedative effects of baclofen, the primary concern is monitoring for weakness, which could impact the patient's safety and mobility.
Question 5 of 5
A client with myasthenia gravis frequently complains of weakness and fatigue. The physician plans to identify whether the client is responding to an overdose of the medication or a worsening of the disease. A tensilon test is performed. Which of the following would indicate that the client is experiencing an overdose of the medication?
Correct Answer: A
Rationale: In a Tensilon test, edrophonium chloride is administered to differentiate between myasthenic crisis (worsening of the disease) and cholinergic crisis (overdose of medication). A temporary worsening of symptoms, such as increased weakness, indicates a cholinergic crisis due to an overdose of anticholinesterase medications. Improvement suggests myasthenic crisis, while no change is inconclusive. Muscle spasms are not specific to an overdose. Therefore, worsening symptoms indicate an overdose.
