Rhythm Strip
The nurse is evaluating the following rhythm strip on a client in the telemetry unit. The client is alert and oriented but is complaining of slight nausea after eating breakfast. What is the nurse's best action?
Complete the remainder of the assessment.
Obtain an order for adenosine IV.
Notify the physician of the symptoms.
Administer the prescribed ace inhibitor.
The Correct Answer is C
A. Complete the remainder of the assessment: While ongoing assessment is important, the rhythm strip shows atrial flutter, a potentially unstable arrhythmia, and the client is experiencing symptoms (nausea after breakfast) which could suggest compromised cardiac output. Completing the remainder assessment delays the necessary intervention.
B. Obtain an order for adenosine IV: Adenosine is typically used for stable supraventricular tachycardia (SVT), not for atrial flutter, as it may not terminate the rhythm. It may slow conduction enough to better visualize flutter waves, but initiating it without a provider's order or further evaluation is inappropriate.
C. Notify the physician of the symptoms: The client’s rhythm strip shows atrial flutter with a rapid ventricular response and the patient is experiencing nausea, which could indicate decreased perfusion or early decompensation. Immediately notifying the provider is the safest and most appropriate action for further evaluation and treatment planning.
D. Administer the prescribed ACE inhibitor: ACE inhibitors are used for blood pressure control or heart failure management, not for acute rhythm disturbances. Administering it would not address the current rhythm or symptoms and could worsen hypotension if cardiac output is compromised.

Correct Answer is B
Explanation
A. Run of premature ventricular beats: While adenosine can occasionally provoke brief ventricular ectopy, this is not its primary or most expected effect. Premature ventricular contractions may occur transiently but are not the hallmark response to this medication.
B. Short period of asystole: Adenosine briefly blocks AV node conduction and can interrupt re-entry pathways, often resulting in a short period of asystole lasting a few seconds. This is an expected effect and reflects the drug’s mechanism in terminating supraventricular tachycardia by interrupting the reentrant pathway.
C. Brief seizure episode: Adenosine does not typically cause seizures. It acts primarily on cardiac tissue and has no significant pro-convulsant effects. A seizure would be an atypical and concerning adverse reaction rather than an expected response.
D. Dramatic increase in blood pressure: Adenosine causes transient vasodilation and may lead to a brief drop in blood pressure or flushing. A dramatic increase in blood pressure would not be expected and could suggest an alternate diagnosis or drug reaction.
Correct Answer is A
Explanation
A. Benign Prostatic Hyperplasia: Tamsulosin is an alpha-1 adrenergic blocker specifically prescribed to relieve urinary symptoms caused by benign prostatic hyperplasia (BPH). It works by relaxing the smooth muscles in the bladder neck and prostate, improving urine flow and decreasing bladder outlet obstruction.
B. Congestive Heart Failure: Tamsulosin is not indicated for heart failure management. Medications used in heart failure typically include ACE inhibitors, beta blockers, diuretics, and aldosterone antagonists not selective alpha-1 blockers like tamsulosin.
C. Rheumatic Fever: Rheumatic fever is linked to valvular heart disease, not urinary retention or prostate enlargement. Tamsulosin does not have a role in its treatment or management.
D. Coronary Artery Disease: Tamsulosin does not have any therapeutic effect in managing coronary artery disease. CAD is typically managed with medications such as beta blockers, statins, antiplatelets, and nitrates, depending on the clinical scenario.
