cardiac

The nurse is reviewing an electrocardiogram rhythm strip. The P waves and QRS complexes areregular. The PR interval is 0.16 second, and QRS complexes measure 0.06 second. The overall heart rate is 64 beats/minute. Which would be a correct interpretation based on these characteristics?

• Sinus bradycardia

• Sick sinus syndrome

• Normal sinus rhythm

• First-degree heart block

A client is wearing a continuous cardiac monitor, which begins to sound its alarm. A nurse sees noelectrocardiographic complexes on the screen. Which is the priority action of the nurse?

• Call a code

• Call the health care provider

• Check the client's status and lead placement

• Press the recorder button on the electrocardiogram console

A client is having frequent premature ventricular contractions. The nurse should place priority onassessment of which item?

• Sensation of palpitations

• Causative factors, such as caffeine

• precipitating factors, such as infection

• Blood pressure and oxygen saturation

The nurse is evaluating a client's response to cardioversion. Which observation would be of highestpriority to the nurse?

• Blood pressure

• Status of airway

• Oxygen flow rate

• Level of consciousness

A client's electrocardiogram strip shows atrial and ventricular rates of 110 beats/minute. The PRinterval is 0.14 second, the QRS complex measures 0.08 second, and the PP and RR intervals areregular. How should the nurse correctly interpret this rhythm

• Sinus dysrhythmia

• Sinus tachycardia

• Sinus bradycardia

• Normal sinus rhythm

The nurse in the medical unit is reviewing the laboratory test results for a client who has beentransferred from the intensive care unit. The nurse notes that a cardiac troponin T level assay wasperformed while the client was in the intensive care unit. The nurse determines that this test wasperformed to assist in diagnosing which condition?

• Heart failure

• Atrial fibrillation

• Myocardial infarction

• Ventricular tachycardia

The nurse is performing an assessment on a client with a diagnosis of left-sided heart failure. Whichassessment component would elicit specific information regarding the client's left-sided heart

function?

• Listening to lung sounds

• Monitoring for organomegaly

• Assessing for jugular vein distention

• Assessing for peripheral and sacral edema

A client with a first-degree heart block has an electrocardiogram (ECG) taken during an episode ofchest pain. The nurse knows that which ECG finding would be an indication of first-degree heart

block?

• Presence of Q waves

• Tall, peaked T waves

• Prolonged PR interval

• Widened QRS complex

The nurse working in a long-term care facility is assessing a client who is experiencing chest pain.The nurse should interpret that the pain is most likely caused by myocardial infarction (MI) on the basis of what assessment findings?

• The client is not experiencing dyspnea

• The client is not experiencing nausea or vomiting

• The pain has not been relieved by rest and nitroglycerin tablets

• The client says the pain began while she was trying to open a stuck dresser drawe

A client has experienced an episode of pulmonary edema. The nurse determines that the client's respiratory status is improving after this episode if which breath sounds are noted

• Rhonch

• Wheezes

• Crackles in the bases

• Crackles throughout the lung fields
