NUR 265 Exam 2 Respiratory and Endocrine Care Questions &
Answers 2026 | High-Yield Review | Graded A+
1. You are a physician assistant student attending physician rounds on the
medicine floor. The attending physician suspects that a patient may have
pheochromocytoma. Which of the following diagnostic tests do you suspect
he will order?
Blood sample to measure Hb A1c.
Plasma levels of catecholamines and metanephrines.
Measurement of cortisol via salivary sample.
Ultrasonography of the thyroid gland.
2. A patient with DKA presents with severe acidosis and hyperkalemia. What
should be prioritized in the treatment plan?
Administer insulin to lower blood glucose and potassium levels.
Monitor glucose levels without treatment.
Start sodium bicarbonate immediately.
Increase IV fluid rate without insulin.
3. Synchronized intermittent mandatory ventilation (SIMV) is one mode of
positive pressure mechanical ventilation. With the SIMV mode of ventilation:
a patient's spontaneous inspiratory efforts (breaths) are assisted
a patient does not have spontaneous breathing
machine-assisted breaths are delivered in between a patient's
spontaneous breaths
4. What is a common symptom associated with pheochromocytoma?
, Bradycardia
Weight gain
Hypertension
Hypoglycemia
5. The hallmark of ARDS is:
increased compliance secondary
refractory hypoxemia
low functional residual capacity
refractory hypercapnia
6. What is the first action a nurse should take upon suspecting a pulmonary
embolism in a patient?
Administer oxygen therapy.
Notify the healthcare provider immediately.
Start intravenous fluids.
Perform a chest X-ray.
7. In order to prevent ventilator-associated/acquired pneumonia (VAP) in an
intubated patient, what should the healthcare provider do?
Provide oral care and suctioning to the patient
Discourage patient visitors
Give prophylactic antibiotics
Maintain intubation for no more than 72 hours
,8. In a scenario where a patient presents with a pulmonary contusion after a car
accident, what nursing intervention should be prioritized to ensure adequate
respiratory function?
Monitor the patient's oxygen saturation and provide supplemental
oxygen as needed.
Encourage the patient to perform deep breathing exercises without
monitoring.
Administer antibiotics immediately to prevent infection.
Prepare the patient for immediate surgery without assessment.
9. The characteristic symptom of pheochromocytoma is
depression
hypertension
weight gain
hypoglycemia
10. Describe how the symptoms of Diabetic Ketoacidosis (DKA) relate to the
underlying metabolic processes.
The symptoms of DKA are unrelated to blood glucose levels.
The symptoms of DKA, such as excessive thirst and frequent
urination, result from high blood glucose levels and the body's
attempt to eliminate ketones.
The symptoms of DKA are primarily caused by infections.
The symptoms of DKA are solely due to dehydration.
11. Describe how tension pneumothorax affects respiratory function in a patient.
, Tension pneumothorax compresses the lung and mediastinum,
leading to impaired gas exchange and respiratory distress.
Tension pneumothorax causes increased lung capacity and improved
oxygenation.
Tension pneumothorax has no effect on respiratory function.
Tension pneumothorax primarily affects the gastrointestinal system.
12. The nurse notes that the client's mechanical ventilator is set to control mode.
The nurse understands that this setting will achieve which action?
Allows for spontaneous respirations
Hyperventilates the client to ensure adequate oxygenation
Provides some breaths for the client but allows the client to breathe
on his/her own also
Allows the lungs to rest
13. Which of the following is a common symptom of Addison's disease?
Hyperactivity
Increased appetite
Fatigue
Weight gain
14. A patient presents with episodic hypertension, palpitations, and sweating.
What condition should be suspected based on these symptoms?
Cushing's disease
Addison's disease
Hyperthyroidism
