Anaphylactic

Coronary artery bypass grafting (CABG) is a treatment modality for which disorder of cardiac function?

Atherosclerosis and unstable angina

A client who developed a deep vein thrombosis during a prolonged period of bed rest has deteriorated as the clot has dislodged, resulting in a pulmonary embolism. Which type of shock is this client at risk of experiencing?

Obstructive shock

The nurse is caring for a client who has just experienced an acute myocardial infarction. Which type of shock is this client likely to experience?

Cardiogenic

A nurse is monitoring a client with a consistent and regular heart rate of 128 beats/min. Which physiologic alteration would be consistent with this finding?

Decrease in ventricular filling time and blood pressure

A client is immobilized following a hip injury. The client has developed lower leg discoloration with edema, pain, and tenderness in the midcalf area. How should the nurse document these clinical findings?

Deep vein thrombosis

A client's electrocardiogram monitor begins to sound an alarm and shows sustained ventricular fibrillation. The client is unconscious and without a pulse. Which priority intervention should the nurse take?

Defibrillate the client

All of the following interventions are ordered STAT for a client stung by a bee who is experiencing severe respiratory distress and faintness. Which priority intervention will the nurse administer first?

Epinephrine

A 20-year-old college student has a pelvic fracture and a severed leg from a motorcycle accident. She lost several units of blood. When the student arrived in the emergency department, her blood pressure was very low, her pulse was high, and her skin was pale. The nurse knows that this client has developed which type of shock?

Hypovolemic

The nurse is assisting a client who had a myocardial infarction 2 days ago during a bath. The client suddenly lost consciousness and the nurse was unable to feel a pulse. Cardiopulmonary resuscitation was begun and the client was connected to the monitor with a gross disorganization without identifiable waveforms or intervals observed. What is a priorityintervention at this time?

Immediate defibrillation

Anaphylactic shock is the most severe form of systemic allergic reaction. Immunologically medicated substances are released into the blood, causing vasodilation and an increase in capillary permeability. What physiologic response often follows the vascular response in anaphylaxis?

Laryngeal edema

The nurse is interpreting an electrocardiogram of a 65-year-old woman. Which should the nurse recognize as representing ventricular depolarization?

QRS complex

Considering the PQRST complex of an electrocardiogram (ECG), which letter designation represents atrial depolarization?

P wave

A client experiencing a sinus arrest would demonstrate which symptom or finding?

Prolonged periods of asystole demonstrated on an electrocardiogram

What is the correct sequence for the generation of electrical impulses in the heart causing ventricular contraction?

SA node - AV node - bundle of His - bundle branches - Purkinje fibers

A 20-year-old college student being treated for a kidney infection developed a temperature of 104ºF (40°C) in spite of treatment with antibiotics. Her pulse was high, her blood pressure was low, and her skin was hot, dry, and flushed. The nurse knows that this client most likely is experiencing which type of shock?

Septic

Which of the following is called the pacemaker of the heart?

Sinoatrial (SA) node

A 28-year-old marathon runner comes to the clinic to obtain a physical exam for a new job. The nurse assesses a regular pulse rate of 52 beats per minute (bpm). Which common dysrhythmia is the nurse aware this client most likely has related to maintaining a large stroke volume?

Sinus bradycardia

An older adult client with a past medical history of diabetes type II and myocardial infarction (MI) is admitted with sudden shortness of breath, palpitations, irregular apical pulse with no pattern, heart rate of 130 and blood pressure of 100/60. The nurse suspects atrial fibrillation (AF) for which reasons? Select all that apply. Tachycardia Hypotension Flutter waves on the ECG Palpitations Irregular rhythm

Tachycardia Palpitations Irregular rhythm

Which client is at the greatest risk of developing rheumatic heart disease?

Teenager with untreated strep throat

Which client will the nurse prioritize to assess first?

The client with sinus arrest

The health care provider is reviewing lab results of a client diagnosed with heart failure. The provider notes that the client's ANP and BNP levels have been increasing and remain significantly elevated. These results would be interpreted as:

The condition is getting progressively worse.

A client is believed to be in cardiac arrest and defibrillation is being performed. What is an aspect of the rationale and physiology of defibrillation treatment?

The goal is to depolarize the entire heart during the passage of current.

A client comes to the emergency room with all the symptoms of a myocardial infarction. Which lab value, known to have a high specificity for myocardial tissue considered the primary biomarker test for diagnosing an MI, does the nurse suspect the physician will order?

Troponin assays

Which dysrhythmia is considered to be the most fatal and requires immediate treatment?

Ventricular fibrillation

A client presents with uncharacteristic chest pain, and his ECG reveals T-wave elevation. This finding suggests an abnormality with which aspect of the cardiac cycle?

Ventricular repolarization

A client has just returned from his surgical procedure. During initial vital sign measurements, the nurse notes that the client's heart rate is 111 beats/minute and the BP is 100/78 (borderline low).
