A nurse in a clinic is caring for a client who has heart failure and is taking digoxin. Which of the following statements by the client indicates the client is experiencing digoxin toxicity?
"I am constipated."
"My vision seems yellow
"My tongue is red and beefy."
"I am gaining weight."
The Correct Answer is B
A. "I am constipated." Constipation is not a common indicator of digoxin toxicity; it may be more related to diet or other medications.
B. "My vision seems yellow." Yellow or blurred vision, also called xanthopsia, is a classic sign of digoxin toxicity and should be reported immediately.
C. "My tongue is red and beefy." A red and beefy tongue may indicate vitamin B12 deficiency, not digoxin toxicity.
D. "I am gaining weight." Weight gain is usually a sign of fluid retention or worsening heart failure, not specifically digoxin toxicity.

Correct Answer is B
Explanation
A. Fatigue. Fatigue can be a common symptom of various health conditions, including heart disease, and is not specific to pacemaker malfunction.
B. Rapid pulse. A rapid pulse or palpitations may signal a malfunction where the pacemaker is pacing too quickly or erratically.
C. Increased urine output. Increased urine output is not related to pacemaker function and does not indicate a malfunction.
D. Sneezing. Sneezing is unrelated to pacemaker malfunction and does not warrant provider notification.
Correct Answer is B
Explanation
A. Creatine kinase-myocardial band (CK-MB) test: While CK-MB is also a marker of myocardial injury, it is less specific than troponin and can be elevated in other conditions, such as muscle injury.
B. Troponin T test. The Troponin T test is highly specific and sensitive for myocardial injury and is considered the gold standard for diagnosing a myocardial infarction. Troponin levels rise within hours of cardiac muscle injury and remain elevated for days, providing an early and reliable indicator of cardiac muscle damage.
C. Brain natriuretic peptide (BNP) test. BNP levels are used to assess heart failure and do not indicate acute cardiac muscle injury.
D. Creatine kinase (CK) test. CK measures overall muscle injury, not specific to cardiac muscle.
