A nurse is preparing to administer IV adenosine to a client. Which of the following effects should the nurse anticipate?

Loss of consciousness

Conversion of atrial fibrillation

Increased heartrate

A period of asystole

Answer and Explanation

The Correct Answer is D

A. Loss of consciousness: Adenosine can cause transient lightheadedness or dizziness, but complete loss of consciousness is not an expected effect during administration. Any syncope would be brief and uncommon.

B. Conversion of atrial fibrillation: Adenosine is effective for terminating paroxysmal supraventricular tachycardia (PSVT) but does not convert atrial fibrillation or atrial flutter. Its action is specific to AV node–dependent reentrant tachycardias.

C. Increased heart rate: Adenosine typically slows conduction through the AV node and may transiently slow the heart rate. An increase in heart rate is not an expected pharmacologic effect.

D. A period of asystole: Adenosine briefly blocks AV nodal conduction, which can result in a transient period of asystole lasting a few seconds. This effect is anticipated and resolves quickly, restoring normal sinus rhythm in PSVT.

Correct Answer is C

Explanation

A. "I know I will need to take methimazole for the rest of my life.": Methimazole therapy is often temporary, used to control hyperthyroidism until definitive treatment or remission occurs. Lifelong use is not necessarily required.

B. "I should take methimazole 1 hr before eating.": Methimazole can be taken with or without food. Timing relative to meals is not critical for its absorption, so taking it strictly one hour before eating is unnecessary.

C. "I should be vigilant with birth control while taking methimazole.": Methimazole can be teratogenic, especially during the first trimester of pregnancy. Effective contraception is important to prevent fetal harm while on this medication.

D. "I should stop taking methimazole when my night sweats go away.": Symptoms may improve before thyroid hormone levels normalize. Stopping methimazole prematurely can lead to relapse of hyperthyroidism, so discontinuation should only occur under provider guidance.

A. A client receives regular insulin 1 hr after a meal. B. A client refuses to get out of bed. C. A client was scheduled to be discharged 2 hr ago. D. A client receives an antibiotic 30 min after the scheduled time.

Correct Answer is A

Explanation

A. A client receives regular insulin 1 hr after a meal: Administering insulin outside the recommended timing can cause hypoglycemia or other adverse effects. This medication error is a reportable event, requiring completion of an incident report for documentation and quality improvement.

B. A client refuses to get out of bed: Patient refusal of activity or care is part of routine nursing documentation and does not constitute an incident that requires a formal report unless it results in harm.

C. A client was scheduled to be discharged 2 hr ago: A delayed discharge is an operational issue rather than a clinical incident. It should be addressed in workflow review but does not require an incident report.

D. A client receives an antibiotic 30 min after the scheduled time: A slight delay in routine medication administration is typically documented in the medical record but does not usually meet the threshold for an incident report unless it results in harm or adverse effects.
