1.

The nurse is caring for a patient with a radial arterial line. Prior to obtaining a reading, which action is most appropriate?

  • A) Flush line for 10 seconds
  • B) Level at sternal angle
  • C) Perform an Allen test
  • D) Reference and zero the line

Explanation

Correct Answer: D. Reference and zero the line
Explanation:
Before obtaining a reading from an arterial line, it is essential to reference and zero the line. This ensures that the pressure monitoring system is accurately calibrated to the patient’s baseline pressure. Zeroing the line eliminates any potential errors caused by changes in atmospheric pressure or equipment calibration, providing accurate readings for the patient's blood pressure and hemodynamics.
2.

The nurse obtains the following 6 second ECG strip on a patient. The nurse interprets this strip as what rhythm? (see attachment)

  • A Ventricular tachycardia
  • B Ventricular fibrillation
  • C Supraventricular tachycardia
  • D Atrial fibrillation

Explanation

Correct Answer: B. Ventricular fibrillation
Explanation:
Ventricular fibrillation (VF) is a shockable rhythm that presents as rapid, erratic electrical activity of the heart. There are no identifiable P waves, QRS complexes, or T waves, and the rhythm is completely disorganized. VF causes the heart to stop pumping blood effectively, leading to a lack of perfusion to vital organs, which is why immediate defibrillation is required.
3.

The nurse notes increasing systemic vascular resistance readings on a patient in the intensive care unit. The nurse understands the effects of this change to include which of the following?

  • A) Increasing pulmonary vascular resistance and respiratory rate.
  • B) Decreasing arterial blood pressure and mean arterial pressure.
  • C) Increasing cardiac output and stroke volume.
  • D) Decreasing cardiac output and increasing oxygen demands.

Explanation

Correct Answer: D. Decreasing cardiac output and increasing oxygen demands.
Explanation:
When systemic vascular resistance (SVR) increases, the heart has to work harder to overcome the increased resistance to blood flow. This leads to a decrease in cardiac output because the heart struggles to pump blood effectively against the higher resistance. The increased resistance places additional strain on the heart, leading to increased oxygen demands as the myocardium requires more oxygen to perform the work of pumping against the higher resistance. This can result in decreased perfusion to tissues, especially if the heart is unable to meet the oxygen demands.
4.

The nurse interprets the patient's 6-second strip as which rhythm? See attachment.

  • A Atrial fibrillation
  • B Normal sinus rhythm with premature atrial contractions (PACs)
  • C Ventricular Fibrillation
  • D Atrial flutter

Explanation

Correct Answer: D. Atrial flutter
Explanation:
The rhythm on the strip shows a regular, rapid rhythm with sawtooth-shaped P waves, which is characteristic of atrial flutter. In atrial flutter, the atria contract very rapidly, often at rates between 250-350 beats per minute, but the ventricular response is typically slower due to a block at the AV node. The hallmark of atrial flutter is the presence of sawtooth waves in the P wave portion of the EKG, which is consistent with what is seen in this strip.
5.

An RN is observing a nursing student who is performing closed suctioning on a hospitalized patient with an endotracheal (ET) tube in place. Which actions by the student requires the RN to intervene? Select all that apply.

  • A) Applies suction while inserting the catheter.
  • B) Adjusts wall suction to 100-120 mm Hg.
  • C) Add air to ET tube and slightly deflates the cuff.
  • D) Hyperoxygenates the patient with 100% FIO2 before suctioning.
  • E) Inserts the catheter until resistance is met.

Explanation

Correct Answers: A. Applies suction while inserting the catheter, E. Inserts the catheter until resistance is met
Explanation:
A. Applies suction while inserting the catheter
This is incorrect. Suction should only be applied after the catheter is inserted into the trachea. Suctioning while inserting the catheter can cause damage to the mucosa and may lead to trauma or discomfort for the patient.
E. Inserts the catheter until resistance is met
This is incorrect. The catheter should not be inserted until resistance is met. Inserting the catheter too deeply can cause trauma to the airway or potentially cause dislodgement of the ET tube. The catheter should be inserted gently and only as far as necessary to suction effectively.
6.

Which assessment data obtained by the nurse when caring for a patient with a left radial arterial line indicates a need for the nurse to take action?

  • A) The left hand is cooler than the right hand.
  • B) The mean arterial pressure is 75 mm Hg.
  • C) The system is delivering 3 ml of flush solution per hour.
  • D) The flush bag and tubing were last changed 2 days previously.

Explanation

Correct Answer: A. The left hand is cooler than the right hand.
Explanation
The cooler left hand compared to the right hand suggests impaired circulation in the left arm, which could indicate that the arterial line is compromising blood flow to the distal extremity. This can be a sign of possible occlusion or kinking of the arterial line, or thrombus formation, all of which could reduce blood flow to the hand and cause ischemia. The nurse should take immediate action to assess the line for patency, check for possible complications, and ensure proper blood flow.
7.

All of the following patients require intravenous push (IVP) medications. The nurse would administer which patient's medication first?

  • A) Scheduled dose of IVP furosemide for a patient displaying signs of shortness of breath
  • B) PRN IVP diphenhydramine for a patient complaining of itching
  • C) PRN IVP morphine for a patient complaining of moderate pain
  • D) Scheduled dose of IVP digoxin for a patient in atrial fibrillation

Explanation

Correct Answer: A. Scheduled dose of IVP furosemide for a patient displaying signs of shortness of breath
Explanation:
The patient exhibiting signs of shortness of breath is at immediate risk for respiratory distress or even respiratory failure, especially if the shortness of breath is due to fluid overload (e.g., congestive heart failure). Furosemide is a diuretic, which helps reduce fluid volume and ease the patient’s breathing. Administering IVP furosemide first is crucial to alleviate the shortness of breath and prevent further complications.
8.

The nurse is monitoring the Pulmonary Artery (PA) catheter and notes a central venous pressure (CVP) reading of 15 mmHg. The nurse anticipates administering the patient which medication?

  • A) Ativan 1 mg intravenous bolus now
  • B) Albumin 20% supplied in 50 ml now
  • C) Furosemide 40 mg intravenous bolus now
  • D) Digoxin 0.25 mg intravenous bolus now

Explanation

Correct Answer: C. Furosemide 40 mg intravenous bolus now
Explanation
A CVP reading of 15 mmHg is elevated, which indicates increased right heart preload, potentially due to fluid overload. Furosemide, a loop diuretic, is used to treat fluid overload by promoting diuresis, thus decreasing the volume of circulating blood, reducing venous pressure, and improving cardiac function. It is the most appropriate choice to address the elevated CVP and reduce the risk of complications like pulmonary edema.
9.

A patient presents to the Emergency Department in SVT (Supraventricular Tachycardia). The patient is assessed with complaints of chest pain and a B/P of 80/40. Synchronized cardioversion is ordered by the MD. What does the nurse anticipate?

  • A) Select "sync" with discharge on the P wave
  • B) Defibrillate at 360 joules
  • C) Defibrillate at 100 joules
  • D) Select "sync" with discharge on the R wave

Explanation

Correct Answer: D. Select "sync" with discharge on the R wave
Explanation:
In synchronized cardioversion, the shock is delivered in sync with the R wave of the QRS complex. This ensures that the shock is timed to avoid causing a lethal arrhythmia like ventricular fibrillation. In SVT, cardioversion is synchronized with the R wave, not the P wave, to ensure proper shock delivery during the depolarization of the ventricles, reducing the risk of harming the patient.
10.

Following surgery, a patient's central venous pressure (CVP) monitor indicates low pressures. Which action will the nurse anticipate taking?

  • A) Increase the IV fluid infusion rate.
  • B) Elevate the head of the patient's bed to 45 degrees.
  • C) Administer IV diuretic medications.
  • D) Document the CVP and continue to monitor.

Explanation

Correct Answer: A. Increase the IV fluid infusion rate.
Explanation:
A low CVP typically indicates hypovolemia or a low circulating blood volume, which can occur after surgery due to blood loss, fluid shifts, or inadequate fluid intake. The primary action the nurse would anticipate is to increase the IV fluid infusion rate to restore blood volume and improve venous return to the heart. This will help raise the CVP to an appropriate level, indicating improved blood circulation and perfusion.
