Explanation

Digoxin is a cardiac glycoside that has a negative chronotropic effect, meaning it slows down the heart rate.
Assessing the apical pulse for a full minute is the most accurate method to determine the heart rate and detect any underlying arrhythmias before administration.
This safety check is critical to prevent profound bradycardia, a potentially dangerous side effect of the medication.
A full 60-second count is necessary to accurately assess the rate, especially if the rhythm is irregular, which is common in patients with heart failure.
Standard clinical practice dictates holding the dose and notifying the provider if the apical pulse is less than 60 beats/minute in an adult.

Option A: Assessing the respiratory rate evaluates pulmonary function. Digoxin's primary and most immediate life-threatening side effect is on the heart rate, not respiration.
Option B: The radial pulse can be inaccurate in patients with congestive heart failure. A condition called a 'pulse deficit' can occur, where weak heart contractions are not transmitted to peripheral arteries, making the radial pulse seem slower than the actual heart rate.
Option C: Extending the duration of a radial pulse count to two minutes does not correct the fundamental problem of potential inaccuracy due to a pulse deficit. The location of the assessment is the issue, not the duration.

Clinical Relevance

Nursing practice connection: Use the key finding related to Nursing assessment prior to medication administration to guide bedside assessment, documentation, and the next nursing action.
Patient Safety: This is a fundamental patient safety measure. Administering digoxin to a bradycardic patient can lead to severe heart block, arrhythmias, and cardiac arrest.
Critical Thinking: Nurses must understand the 'why' behind their actions. Knowing that CHF can cause a pulse deficit is the critical thinking link that makes the apical pulse the only correct choice.
What if?: What if the patient's apical pulse is 62 bpm but very irregular? The nurse should still administer the medication as the rate is above 60, but must document the irregular rhythm and continue to monitor the patient closely for any changes.

How to Approach the Question

First, identify the drug in the question: Digoxin.
Recall the primary action and major side effects of Digoxin. Its main action is to strengthen heart contractions, but a critical side effect is that it slows the heart rate (bradycardia).
Consider the patient's diagnosis: Congestive Heart Failure (CHF). Patients with CHF are prone to arrhythmias and may have a pulse deficit.
Based on the risk of bradycardia and the potential for a pulse deficit, determine the most accurate way to assess the heart rate. The apical pulse is the gold standard.
Evaluate the options. Eliminate respiratory rate as it's irrelevant. Eliminate radial pulse options because they are less accurate than the apical pulse in this situation.
Conclude that assessing the apical pulse for a full minute is the necessary and safest nursing action.
