WITH DETAILED VERIFIED ANSWERS (100% CORRECT
ANSWERS) /ALREADY GRADED A+
VERSION 1
Question 1
A 45-year-old male presents to the ED with sudden onset of severe, tearing chest pain radiating
to his back. He has a history of poorly controlled hypertension. His blood pressure is 190/110
mmHg in the right arm and 160/90 mmHg in the left arm. What is the most critical differential
diagnosis?
A) Acute Myocardial Infarction (AMI)
B) Pulmonary Embolism (PE)
C) Aortic Dissection
D) Pericarditis
E) Esophageal Spasm
Correct Answer: C) Aortic Dissection
Rationale: Sudden, severe, tearing chest pain radiating to the back, especially with a
significant blood pressure differential between the arms, is a classic presentation of
aortic dissection, a life-threatening emergency.
Question 2
A 28-year-old female presents to the ED after a motor vehicle crash. She is conscious, but her
respirations are shallow at 28/min, and she has significant bruising and paradoxical movement of
her right chest wall. What is the most likely injury?
A) Pneumothorax
B) Hemothorax
C) Flail Chest
D) Cardiac Contusion
E) Simple Rib Fracture
Correct Answer: C) Flail Chest
Rationale: Flail chest occurs when three or more adjacent ribs are fractured in two
or more places, creating a free-floating segment of the chest wall that moves
,paradoxically (inward on inspiration, outward on expiration), leading to ineffective
ventilation and respiratory distress.
Question 3
When managing a client with suspected increased intracranial pressure (ICP), which of the
following is the priority nursing intervention?
A) Administer a rapid infusion of IV fluids.
B) Keep the head of the bed flat.
C) Maintain head and neck in neutral alignment.
D) Encourage coughing and deep breathing.
E) Administer a sedative to keep the client awake.
Correct Answer: C) Maintain head and neck in neutral alignment.
Rationale: Maintaining neutral head and neck alignment prevents compression of the
jugular veins, facilitating venous outflow from the brain and helping to reduce ICP.
Other interventions like elevating the head of the bed (30 degrees) also help.
Question 4
A 6-year-old child presents to the ED with inspiratory stridor, drooling, high fever, and appears
anxious and tripoding. What is the most critical intervention?
A) Forcefully inspect the oropharynx to visualize the epiglottis.
B) Administer nebulized albuterol.
C) Prepare for immediate intubation in a controlled environment, avoiding stimulation of the
airway.
D) Obtain a complete blood count (CBC) immediately.
E) Provide oral antibiotics.
Correct Answer: C) Prepare for immediate intubation in a controlled environment,
avoiding stimulation of the airway.
Rationale: These are classic signs of epiglottitis, a life-threatening upper airway
obstruction. Any manipulation of the airway (like inspecting the oropharynx) can
trigger laryngospasm and complete airway occlusion. Intubation is the priority.
Question 5
A client presents with a sudden onset of severe, sharp, unilateral flank pain radiating to the
,groin, accompanied by hematuria, nausea, and vomiting. What is the most likely cause?
A) Appendicitis
B) Cholecystitis
C) Nephrolithiasis (Kidney Stones)
D) Pyelonephritis
E) Pancreatitis
Correct Answer: C) Nephrolithiasis (Kidney Stones)
Rationale: Acute, severe, colicky flank pain radiating to the groin, often with
hematuria, nausea, and vomiting, is highly characteristic of nephrolithiasis as the
stone moves through the ureter.
Question 6
When caring for a client with a suspected spinal cord injury after trauma, what is the priority
initial intervention?
A) Administer pain medication.
B) Obtain a detailed neurological history.
C) Immobilize the cervical spine.
D) Assess motor strength in all extremities.
E) Prepare for a CT scan of the spine.
Correct Answer: C) Immobilize the cervical spine.
Rationale: Protecting the cervical spine from further injury is paramount in any
suspected spinal cord injury to prevent worsening neurological deficits. This is done
with a cervical collar and backboard.
Question 7
A client presents with signs of septic shock. Which of the following hemodynamic parameters
would the nurse expect?
A) Increased systemic vascular resistance (SVR), normal cardiac output (CO).
B) Decreased SVR, increased CO, hypotension.
C) Increased SVR, decreased CO, hypertension.
D) Normal SVR, decreased CO, normal blood pressure.
E) Increased SVR, normal CO, hypotension.
, Correct Answer: B) Decreased SVR, increased CO, hypotension.
Rationale: Septic shock is characterized by profound vasodilation (decreased SVR)
leading to hypotension. The body attempts to compensate by increasing cardiac
output initially, resulting in a "warm shock" state.
Question 8
A client presents with an open fracture of the tibia. After ensuring ABCs, what is the next
priority intervention?
A) Administer antibiotics.
B) Reduce the fracture.
C) Cover the open wound with a sterile dressing.
D) Assess distal pulses and neurological function.
E) Splint the extremity.
Correct Answer: C) Cover the open wound with a sterile dressing.
Rationale: After assessing ABCs, protecting the open wound from further
contamination is critical to prevent infection in an open fracture. Splinting usually
follows this.
Question 9
A client with suspected acute appendicitis presents with right lower quadrant pain, rebound
tenderness, and a positive Rovsing's sign. What is the nurse's priority action?
A) Administer oral analgesics.
B) Prepare for surgical consultation and NPO status.
C) Encourage ambulation to relieve gas.
D) Provide a heating pad to the abdomen.
E) Administer a laxative for constipation.
Correct Answer: B) Prepare for surgical consultation and NPO status.
Rationale: Acute appendicitis is a surgical emergency. The priority is to prepare the
client for potential appendectomy, which includes keeping them NPO to prevent
aspiration during surgery.
