Question

The physician orders Dopamine drip to be initiated at 2 mcg/kg/min for a patient with a slow heart rate. The patient weighs 78 kg. Dopamine 400 mg is supplied in 'normal saline. At what rate would the nurse initiate the IV infusion (in mL/hr)? Round to the nearest tenths.

Answer 1

Correct Answers:

5.9

Rationale :

🧮Required dose: 2 mcg × 78 kg × 60 min = 9,360 mcg/hr. 🔄Convert to milligrams: 9,360 mcg ÷ 1,000 = 9.36 mg/hr. 💉Assuming the standard concentration is 400 mg in 250 mL, the concentration is 1.6 mg/mL. 📐Infusion rate: 9.36 mg/hr ÷ 1.6 mg/mL = 5.85 mL/hr, rounded to 5.9 mL/hr.

📌Core Message:

A dopamine dosage of 2 mcg/kg/min for 78 kg using 400 mg in 250 mL requires an infusion rate of 5.9 mL/hr.

Answer 2

Correct Answers:

synchronized intermittent mandatory ventilation

Rationale :

🫁SIMV delivers a preset number of mandatory breaths synchronized with the patient’s respiratory effort.

🌬️The patient can breathe spontaneously between mandatory breaths using their own tidal volume.

⚙️This mode supports ventilation while encouraging respiratory-muscle activity.

📉It can also be used during gradual ventilator weaning.

📌Core Message:

SIMV provides synchronized mandatory breaths while allowing spontaneous breathing between them.

Answer 3

Correct Answers:

Decrease in venous return

Rationale :

📈Higher PEEP increases intrathoracic pressure.

❤️This pressure reduces venous blood flow returning to the right side of the heart.

📉Reduced preload decreases stroke volume and cardiac output, producing hypotension.

🩺The nurse should assess hemodynamic status after increases in PEEP.

📌Core Message:

Excessive PEEP can decrease venous return and cardiac output, causing hypotension.

Answer 4

Correct Answers:

Suctioning is done as indicated by patient assessment.

Rationale :

🫁Endotracheal suctioning should be performed only when clinically indicated.

🔊Indications include visible or audible secretions, coarse breath sounds, decreased oxygen saturation, or increased airway pressure.

⚠️Unnecessary suctioning can cause hypoxemia, mucosal trauma, dysrhythmias, and increased intracranial pressure.

👀Assessment-based suctioning reduces avoidable complications.

📌Core Message:

Endotracheal suctioning should be performed as needed based on respiratory assessment findings.

Answer 5

Correct Answers:

Coughing or attempting to talk

Rationale :

🚨A high inspiratory-pressure alarm indicates increased resistance to airflow.

😷Coughing, biting the tube, retained secretions, bronchospasm, or kinked tubing can increase airway pressure.

🫁The nurse should immediately assess the patient and ventilator circuit.

🛡️Airway patency and adequate ventilation are the priorities.

📌Core Message:

High-pressure alarms commonly result from coughing, secretions, bronchospasm, tube obstruction, or kinked tubing.

Answer 6

Correct Answers:

Initiating an Atracurium infusion

Rationale :

🫁Severe ARDS may require complete synchronization with a nontraditional ventilation strategy.

💊The patient remains dyssynchronous despite propofol and fentanyl, indicating that sedation and analgesia are already being provided.

🧠Atracurium, a neuromuscular blocker, can temporarily eliminate spontaneous muscle activity and improve ventilator synchrony.

🛡️Continuous sedation, analgesia, respiratory support, and neuromuscular monitoring are essential because paralysis provides no sedation or pain control.

📌Core Message:

Persistent ventilator dyssynchrony in severe ARDS despite adequate sedation may require short-term neuromuscular blockade.

Answer 7

Correct Answers:

"Our main concern is avoiding the development of a widespread infection called sepsis."

Rationale :

🦠Ventilator-associated pneumonia is a serious hospital-acquired infection.

🩸The infection can spread into the bloodstream and cause sepsis or septic shock.

🫁Treatment usually involves cultures, appropriate antibiotics, pulmonary hygiene, and supportive care.

🛡️Preventive measures include oral care, head-of-bed elevation, hand hygiene, and daily evaluation for ventilator removal.

📌Core Message:

A major danger of ventilator-associated pneumonia is progression to sepsis and multisystem deterioration.

Answer 8

Correct Answers:

Increase the Fentanyl and/or Midazolam IV infusion rates.

Rationale :

⚠️Restlessness, tachypnea, and reaching for the endotracheal tube indicate inadequate sedation and possible self-extubation risk.

📊The prescribed RASS target is 0 to −2, but the client’s behavior indicates a more agitated score.

💊Titrating fentanyl and/or midazolam upward according to the prescription can improve comfort and ventilator synchrony.

🫁The nurse should simultaneously assess for pain, hypoxemia, secretions, tube obstruction, and other reversible causes of agitation.

📌Core Message:

A ventilated patient who is agitated and attempting to remove the tube requires assessment and titration of prescribed sedation toward the ordered RASS target.

Answer 9

Correct Answers:

Hyperoxgenate prior to suctioning.

Rationale :

🫁Suctioning temporarily removes oxygen from the airway and can cause hypoxemia.

💨Hyperoxygenation before suctioning increases the patient’s oxygen reserve.

⏱️Each suction pass should be brief, with oxygenation and reassessment between passes.

❤️The nurse should monitor oxygen saturation, heart rate, rhythm, and patient tolerance.

📌Core Message:

Hyperoxygenation before endotracheal suctioning reduces the risk of procedure-related hypoxemia.

Answer 10

Correct Answers:

Uncompensated respiratory acidosis; hyperoxgenated

Rationale :

🧪The pH of 7.31 indicates acidemia. 🫁The PaCO₂ of 48 mm Hg is elevated, identifying a respiratory cause. ⚖️The bicarbonate of 22 mEq/L is not elevated, so meaningful metabolic compensation has not occurred. 💨The PaO₂ of 115 mm Hg and oxygen saturation of 99% indicate hyperoxygenation.

📌Core Message:

Low pH with elevated PaCO₂ and no bicarbonate elevation indicates uncompensated respiratory acidosis, while PaO₂ 115 mm Hg indicates hyperoxygenation.
