NUR 254 Exam 4 Questions With Accurate Answers 100%
Guarantee Pass 2026/2027
1. If a patient presents with symptoms of sepsis and shows signs of shock, what
should be your immediate course of action?
Administer pain relief and monitor the patient.
Wait for lab results before taking any action.
Transfer the patient to a different facility immediately.
Initiate fluid resuscitation and start broad-spectrum antibiotics.
2. Describe the physiological changes that occur in the body during Diabetic
Ketoacidosis (DKA).
In DKA, insulin levels are elevated, causing hypoglycemia and
dehydration.
In DKA, the body experiences a lack of insulin, leading to increased
ketone production and metabolic acidosis.
In DKA, glucose is converted to glycogen, resulting in increased
energy levels.
In DKA, the body retains water, leading to hypervolemia.
3. What are common signs and symptoms that indicate a patient may be in
sepsis?
Nausea and vomiting
Fever, increased heart rate, and confusion
Severe headache and dizziness
Low blood pressure and rash
,4. You are treating an alert, responsive patient suffering from hypothermia. Your
first priority in caring for this patient is:
Determining the patient's temperature
Immediately transporting the patient
Airway maintenance
Removing the patient from the cold and preventing further heat
loss
5. What does the red triage category indicate in emergency situations?
Immediate treatment is required.
Treatment can be delayed.
Patient is deceased.
No treatment is necessary.
6. Describe how precedex functions as a sedative in emergency medical
situations.
Precedex is a narcotic that induces deep anesthesia.
Precedex is an alpha-2 adrenergic agonist that provides sedation
without significant respiratory depression.
Precedex is used to treat severe allergic reactions.
Precedex acts as a muscle relaxant during surgeries.
7. What is the definition of 'emergent' in the context of emergency
departments?
A condition requiring immediate medical attention.
A non-life-threatening situation.
, A condition that can wait for treatment.
A routine medical procedure.
8. *** CARDIOGENIC SHOCK is categorized by _________
vasodilation
mechanical interference
low circulating volume
reduction in cardiac output
9. Describe how Midazolam contributes to patient management during medical
emergencies.
Midazolam acts as a stimulant to increase patient alertness during
emergencies.
Midazolam is used to induce sedation, helping to calm patients and
facilitate procedures.
Midazolam is primarily used to treat infections in emergency settings.
Midazolam is used to manage blood pressure in critical care.
10. In a scenario where a patient presents with a crush injury to the leg, what
immediate management step should be prioritized?
Immediately apply ice to reduce swelling.
Perform a surgical intervention right away.
Administer pain medication without further assessment.
Assess and relieve any pressure on the affected limb.
11. Describe the physiological changes that occur during neurogenic shock.
, Neurogenic shock is characterized by heart failure and fluid overload.
Neurogenic shock is caused by excessive blood volume and results in
increased heart rate.
Neurogenic shock involves loss of sympathetic tone, leading to
vasodilation and decreased blood pressure.
Neurogenic shock occurs due to an infection and leads to systemic
inflammation.
12. Describe how methamphetamine affects a patient's physiological state.
Methamphetamine increases neurotransmitter activity, leading to
heightened energy, alertness, and increased heart rate.
Methamphetamine primarily affects digestion and appetite.
Methamphetamine has no significant effect on physiological states.
Methamphetamine decreases neurotransmitter activity, resulting in
drowsiness and lethargy.
13. Hyperkalemia manifests on the ECG.
Striking pointed P waves
Prolonged QT interval
Wide QRS complex and high spiky T wave
ST segment depression and T wave inversion
14. If a patient arrives in the emergency room exhibiting signs of
methamphetamine use, what immediate action should be taken?
Administer sedatives to calm the patient.
Perform a surgical intervention immediately.
