Client Health and Safety Specifications Questions
Question 1 of 5
Which assessment data indicate to the nurse the client diagnosed with ARDS has experienced a complication secondary to the ventilator?
Correct Answer: C
Rationale: The correct answer is C because asymmetrical chest expansion indicates a potential complication such as pneumothorax, a common complication of mechanical ventilation in ARDS. This can lead to decreased lung compliance and oxygenation. A: Urine output may indicate renal function but is not directly related to ventilator complications. B: Pulse oximeter reading greater than 95% indicates good oxygenation, which is a positive finding. D: Sinus tachycardia can be due to various reasons and is not specific to ventilator complications.
Question 2 of 5
The nurse will monitor for clinical manifestations of hypercapnia when a patient in the emergency department has
Correct Answer: A
Rationale: The correct answer is A: chest trauma and multiple rib fractures. This condition can lead to impaired ventilation and hypoventilation, resulting in retention of carbon dioxide (hypercapnia). The other choices do not directly lead to hypercapnia. B: carbon monoxide poisoning affects oxygen transport, not carbon dioxide levels. C: left-sided ventricular failure causes hypoxia, not hypercapnia. D: tachypnea in ARDS may lead to hypocapnia, not hypercapnia. Therefore, chest trauma with rib fractures is the most likely scenario to cause hypercapnia.
Question 3 of 5
When admitting a patient in possible respiratory failure with a high PaCO2, which assessment information will be of most concern to the nurse?
Correct Answer: A
Rationale: The correct answer is A: The patient is somnolent. This indicates potential respiratory fatigue, requiring immediate intervention. Somnolence suggests worsening respiratory function, leading to further CO2 retention. SpO2 at 90% (choice B) is concerning but not as urgent as hypercapnia. Weakness (choice C) is a common symptom but not as critical as somnolence. Blood pressure of 162/94 (choice D) is high but not directly related to respiratory failure. Prioritize addressing the somnolence to prevent further deterioration.
Question 4 of 5
A 26-year-old patient is admitted to the hospital in severe respiratory distress. His oxygen saturations are 80% despite supplemental oxygen provided by facemask. The physician decides to intubate the patient to help with his breathing oxygenation. Which medication would the nurse most likely administer when assisting with intubation?
Correct Answer: A
Rationale: The correct answer is A: Midazolam (Versed). Midazolam is a benzodiazepine used for sedation and anxiolysis before intubation to ensure patient comfort and cooperation. It has rapid onset and short duration, making it ideal for this situation. Zolpidem (B) is a sedative-hypnotic used for insomnia, not suitable for intubation. Phentermine (C) is a weight-loss medication and has no role in intubation. Modafinil (D) is a wakefulness-promoting agent and is not used for intubation. In summary, Midazolam is the correct choice for its sedative properties in facilitating intubation, while the other options are not appropriate for this scenario.
Question 5 of 5
A patient is placed on volume-cycled ventilation. The nurse plans care for this client based on which characteristic of this method of ventilation?
Correct Answer: A
Rationale: The correct answer is A because volume-cycled ventilation delivers a set volume with each breath, ensuring a consistent tidal volume. This characteristic is beneficial in overcoming airway resistance changes, as the set volume helps maintain adequate ventilation despite changes in lung compliance or airway resistance. Option B refers to trigger mechanism, not characteristic of volume-cycled ventilation. Option C is a true statement, but it does not fully capture the reason why volume-cycled ventilation is chosen. Option D is incorrect as it inaccurately describes pressure-controlled ventilation.
