Free TCR-Nurse MCQ Questions and Answers

Question 1

Following a tractor accident, a 27-year-old patient is brought into the emergency room with an open, contaminated fracture of the tibia.  Which of the following details should you particularly try to get from the patient?

Accepted Answer

Date of last tetanus shot.

Answer

For all open infected wounds, the time since the most recent tetanus vaccine is particularly crucial.  However, if the patient is not immunized, has had fewer than three immunizations, or is unsure about immunization, then the patient should receive both the tetanus toxoid and tetanus immune globulin because tetanus toxoid does not immediately confer immunity while tetanus immune globulin provides temporary immunity right away. Patients who have had three or more immunizations.

Question 2

Which type of concussion would be considered in the case of a soccer player who was struck in the head by a ball and experienced temporary bewilderment for ten minutes after the injury before it went away?

Accepted Answer

Grade 1

Answer

Grade 1 (Mild): Temporary confusion without coma, and symptoms go away in about 15 minutes.

Question 3

The central venous pressure (CVP) of an adult patient is being monitored, and the pressure is decreasing. Which method is used to confirm hypovolemia?

Accepted Answer

Rapid fluid infusion of 250 to 500 mL and then evaluation in 10 minutes.

Answer

A fast fluid infusion of 250 to 500 mL may be administered because hypovolemia is the most frequent cause of a decline in CVP.  If the pressure begins to drop again after ten minutes, hypovolemia is likely the cause. Always utilize serial readings to confirm an increase or reduction. The right atrium, right ventricle, and blood flow back into the heart are all evaluated using the CVP, which is the pressure in the superior vena cava close to the right atrium. Depending on the method of measurement, the normal ranges for CVP are 0 to 8 cm H2O or 2 to 6 mm Hg.

Question 4

What are the main symptoms of a broken mandible?

Accepted Answer

malocclusion and ecchymosis of floor of the mouth.

Answer

Malocclusion and ecchymosis of the mouth floor are the main symptoms of mandibular fracture. There can be a gap between the teeth.  Blunt trauma causes the majority of wounds, and numerous fractures may be present.  Although bleeding may happen if the fracture tears an artery, such as the inferior alveolar artery, bleeding from blunt injuries is uncommon. Most of the time, pressure application, fracture reduction, and/or local anesthetic with epinephrine are enough to stop the bleeding.

Question 5

A 30-year-old patient with an ipsilateral distal radius fracture and elbow dislocation complains of excruciating forearm pain. Analgesia does not relieve the pain.  What should the nurse be on the lookout for?

Accepted Answer

Compartment syndrome.

Answer

An early symptom of compartment syndrome, which is typically brought on by bleeding into the tissue, is severe, growing pain that is not eased by analgesia and is localized distal to the injury (in this case, the forearm). Upon examination, the compartment feels tight, and passive muscular stretching may cause pain. Paraesthesia and hypoaesthesia could develop in patients. Finding a pulse below the injury should not lead the nurse to believe that compartment syndrome is ruled out because motor weakness and vascular insufficiency are late signs.
