The nurse is caring for a patient with a pulmonary artery catheter. The nurse assesses the pressure monitoring system and would immediately correct which finding?
- A) The pressure bag is inflated to 100 mmHg.
- B) Normal saline is used for the flush bag.
- C) The transducer is zeroed with good waveform noted.
- D) The connections are secure.
Explanation
Explanation
The pressure bag should be inflated to 300 mmHg to maintain a constant flush pressure of the pressure monitoring system. This ensures a steady, reliable flow of the flush solution through the catheter and prevents clots or occlusions in the catheter. A pressure bag set at 100 mmHg is insufficient and could cause inaccurate pressure readings or system malfunctions.
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
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.
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
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.
The nurse is assisting with a patient being intubated at the bedside. After tube endotracheal tube insertion and the cuff inflation, what are the next appropriate actions to confirm placement before securing the airway? Select all that apply.
- A) Administer a sedative and paralytic agent
- B) Order a chest x-ray
- C) Use an end-tidal CO2 detector
- D) Auscultate for bilateral breath sounds
- E) Obtain ABGs
Explanation
C. Use an end-tidal CO2 detector
D. Auscultate for bilateral breath sounds
C. Use an end-tidal CO2 detector
Explanation: The most reliable and immediate method to confirm correct placement of the ET tube is the use of an end-tidal CO2 detector. This device detects the presence of exhaled CO2, which confirms that the tube is in the trachea and not the esophagus. A positive CO2 reading is a clear indication that the tube is properly placed in the lungs.
D. Auscultate for bilateral breath sounds
Explanation: Auscultating both sides of the chest is important to confirm that the ET tube is in the trachea. If the tube is in the correct position, breath sounds should be heard equally on both sides of the chest. If breath sounds are only heard on one side, it could indicate that the tube is in one of the mainstem bronchi, and the tube needs to be repositioned.
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
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.
A patient is intubated and placed on continuous mechanical ventilation. Which equipment is most important for the nurse to keep at this patient's bedside?
- A) Pulse oximeter
- B) Nasal cannula
- C) Manual resuscitation bag
- D) Chest tube drainage set-up
Explanation
Explanation:
A manual resuscitation bag (ambu bag) is the most important piece of equipment to keep at the bedside of an intubated patient on mechanical ventilation. In the event of ventilator failure or disconnection, the nurse must be able to provide manual ventilation to the patient to ensure oxygenation and ventilation until the issue is corrected. This is a critical backup for emergencies such as equipment malfunction or tube displacement.
Which nursing action would be the highest priority when suctioning a patient with an oral endotracheal (ET) tube or tracheostomy?
- A) Give antianxiety medications 30 minutes before suctioning.
- B) Instill 5 mL of normal saline into the tube before suctioning.
- C) Hyperoxygenate with 100% FIO2 before suctioning.
- D) Auscultate lung sounds after suctioning is complete.
Explanation
Explanation:
Before suctioning a patient with an oral ET tube or tracheostomy, it is essential to hyperoxygenate the patient with 100% oxygen (FIO2). Suctioning can lead to oxygen desaturation due to the removal of air from the respiratory tract and the potential for hypoxia during the procedure. Hyperoxygenating the patient helps to maintain adequate oxygen levels during the suctioning process, especially in patients who may already have compromised respiratory function.
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
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.
A patient on mechanical ventilation becomes very frustrated when trying to communicate. Which intervention should the nurse perform to assist the patient?
- A) Ask a close family member to assist with communication.
- B) Encourage the patient to use sign language to communicate.
- C) Ask the patient to write or spell words with an alphabet board.
- D) Consult speech therapy to teach the patient voice exercises.
Explanation
Explanation
Patients on mechanical ventilation may be unable to speak, leading to frustration. One effective way to help patients communicate is by providing an alternative method, such as using an alphabet board to write or spell out words. This allows the patient to express their needs and reduce feelings of frustration. It's a practical and immediate intervention that can be used when verbal communication is not possible.
The healthcare provider orders positive end-expiratory pressure (PEEP) to be added to the settings of a mechanically ventilated patient. Which is the most important information for the nurse to obtain when monitoring for the effectiveness of this intervention?
- A) Oxygen saturation
- B) Tidal volume
- C) Respiratory rate
- D) Arterial blood pressure
Explanation
Explanation:
PEEP is used to prevent the collapse of alveoli at the end of exhalation, improving oxygenation. The most important parameter to monitor for the effectiveness of PEEP is oxygen saturation (SpO2). An increase in oxygen saturation indicates improved oxygenation, which is the primary goal of applying PEEP. Monitoring oxygen saturation helps the nurse assess if PEEP is effectively enhancing gas exchange and maintaining adequate oxygen levels.
