MS1 Exam 3 Practice

A patient in sinus bradycardia, with a heart rate of 45 beats per minute and blood pressure of 82/60 mm Hg, reports dizziness. Which intervention should the nurse anticipate will be prescribed?

• Administer digoxin

• Defibrillate the patient

• Continue to monitor the patient

• Prepare for transcutaneous pacing

The nurse in a medical unit is caring for a patient with heart failure. The patient suddenly develops extreme dyspnea, tachycardia, and lung crackles. The nurse immediately asks another nurse to contact the primary health care provider and prepares to implement which priority interventions? Select all that apply.

• Administering oxygen

• Insert a Foley catheter

• Administering furosemide

• Administering morphine sulfate intravenously

• Transporting the patient to the coronary care unit

A patient with a history of type 2 diabetes is admitted to the hospital with chest pain. The client is scheduled for a cardiac catheterization. Which medication would need to be withheld for 24 hours before the procedure and for 48 hours after the procedure?

• Glipizide

• Metformin

• Repaglinide

• Regular Insulin

The nurse notes that a patient with sinus rhythm has a premature ventricular

contraction that falls on the T wave of the preceding beat. The patient's rhythm suddenly changes to one with no P waves, no definable QRS complexes, and coarse wavy lines of varying amplitude. How should the nurse interpret this rhythm?

• Asystole

• Atrial fibrillation

• Ventricular fibrillation

• Ventricular tachycardia

A patient with myocardial infarction is developing cardiogenic shock. What condition should the nurse carefully assess the client for?

• Pulsus paradoxus

• Ventricular dysrhythmias

• Rising diastolic blood pressure

• Falling central venous pressure

The nurse is caring for a patient who had a resection of an abdominal aortic aneurysm yesterday. The client has an intravenous (IV) infusion at a rate of 150 mL/hr, unchanged for the last 10 hours. The patient’s urine output for the last 3 hours has been 90, 50, and 28 mL (28 mL is most recent). The client’s blood urea nitrogen level is 35 mg/dL (12.6 mmol/L), and the serum creatinine level is 1.8 mg/dL (159 mcmol/L), measured this morning. Which

nursing action is the priority?

• Check the serum albumin level

• Check the urine specific gravity

• Continue monitoring urine output

• Call the primary health care provider

The nurse is assessing the neurovascular status of a patient who returned to the surgical nursing unit 4 hours ago after undergoing aortoiliac bypass graft. The affected leg is warm, and the nurse notes redness and edema. The pedal pulse is palpable. How should the nurse interpret the client’s neurovascular status?

• The neurovascular status is normal because of increased blood flow through the leg

• The neurovascular status is moderately impaired, and the surgeon should be called

• The neurovascular status is slightly deteriorating and should be monitored for another hour

• The neurovascular status shows adequate arterial flow, but venous complications are arising

The nurse is evaluating the condition of a patient after pericardiocentesis performed to treat cardiac tamponade. Which observation would indicate that the procedure was effective?

• Muffled heart sounds

• Patient reports dyspnea

• A rise in blood pressure

• Jugular venous distention

The nurse reviews the arterial blood gas results of a patient and notes the following:pH7.45,Paco2of30mmHg(30mmHg),andHCO3– of20mEq/L (20 mmol/L). The nurse analyzes these results as indicating which condition?

• Metabolic acidosis, compensated

• Respiratory alkalosis, compensated

• Metabolic alkalosis, uncompensated

• Respiratory acidosis, uncompensated

The nurse is caring for a patient with diabetic ketoacidosis and documents that the client is experiencing Kussmaul’s respirations. Which patterns did the nurse observe? Select all that apply.

• Respirations that are shallow

• Respirations that are increased in rate

• Respirations that are abnormally slow

• Respirations that are abnormally deep

• Respirations that cease for several seconds
