The nurse assesses a client who is prescribed digoxin. The client reports nausea and seeing green halos. Which action should the nurse perform?

Administer the dose later in the day when their nausea subsides

Assess the client's apical rate

Contact the physician for STAT serum potassium level

Administer the client's prescribed dose intravenously

Answer and Explanation

The Correct Answer is B

A. Administer the dose later in the day when their nausea subsides: Delaying the dose does not address the underlying concern of potential digoxin toxicity. Symptoms like nausea and visual disturbances suggest toxicity and require immediate assessment rather than postponement.

B. Assess the client's apical rate: The first and most appropriate nursing action is to assess the apical heart rate for one full minute, as bradycardia is a key indicator of digoxin toxicity. If the rate is below 60 bpm, the dose should be held, and the provider should be notified.

C. Contact the physician for STAT serum potassium level: Hypokalemia increases the risk of digoxin toxicity, but while checking potassium is important, it is not the first step. Assessment of heart rate is more immediately critical in evaluating the need to hold the medication.

D. Administer the client's prescribed dose intravenously: Administering the dose especially IV when the client has symptoms of toxicity could worsen the situation. Digoxin should be held, not given, until further evaluation and provider notification.

Correct Answer is B

Explanation

A. Administer amiodarone IV push followed by a continuous infusion: Amiodarone is part of the Advanced Cardiac Life Support (ACLS) algorithm for ventricular fibrillation (VF) or pulseless ventricular tachycardia, but it should only be given after confirming the rhythm and initiating basic life support steps, including pulse check.

B. Establish unresponsiveness and check the carotid pulse: The rhythm strip shows ventricular fibrillation, a life-threatening arrhythmia. However, before initiating advanced interventions such as defibrillation, the nurse must first confirm the client is unresponsive and pulseless, which is the correct initial action according to ACLS protocols.

C. Immediately defibrillate the client using the synchronous mode: Defibrillation is the correct treatment for VF, but it must be done in unsynchronized mode. Additionally, it is not appropriate to defibrillate until pulselessness is confirmed. Synchronized mode is used for rhythms like unstable SVT or atrial fibrillation not VF.

D. Initiate a rapid response call and increase the monitor’s sensitivity: A rapid response team is called for deteriorating patients who are still responsive. If the client is unresponsive and pulseless, a code blue or cardiac arrest protocol should be initiated, not just a rapid response. Monitor sensitivity adjustments are irrelevant in a confirmed life-threatening rhythm.

A. Complete the remainder of the assessment. B. Obtain an order for adenosine IV. C. Notify the physician of the symptoms. D. Administer the prescribed ace inhibitor.

Correct Answer is C

Explanation

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.
