Question 1 of 5
The nurse is caring for a patient who was in a motor vehicle accident that resulted in cervical trauma to C4. Which assessment is the priority?
Correct Answer: A
Rationale: Respirations: C4 injuries compromise the phrenic nerve, which controls the diaphragm. A high cervical spine injury can lead to respiratory failure, making airway and breathing the top priority. Pulse: While monitoring circulation is important, breathing takes priority in a C4 injury due to the risk of respiratory paralysis. Temperature: Temperature regulation may be affected due to autonomic dysfunction, but airway and breathing remain the priority. Blood Pressure: While spinal cord injuries can cause neurogenic shock (low BP, bradycardia), ensuring airway and breathing comes first.
Question 2 of 5
A nurse is reviewing the electrocardiogram (ECG) results. Which portion of the conduction system does the nurse consider when evaluating the P wave?
Correct Answer: B
Rationale: SA Node: The SA (sinoatrial) node initiates electrical impulses and is responsible for atrial depolarization, which produces the P wave on an ECG. This makes it the correct answer. AV Node: The AV node is responsible for delaying electrical impulses before they pass to the ventricles, but it does not generate the P wave. It affects the PR interval rather than the P wave itself. Purkinje Fibers: The Purkinje fibers play a role in ventricular contraction (QRS complex), not in the formation of the P wave. Bundle of HIS: The Bundle of HIS transmits impulses to the ventricles and is involved in ventricular depolarization, not atrial activity. It is not responsible for the P wave.
Question 3 of 5
Convert from Fahrenheit to Celsius: 98.6
Correct Answer: 37
Rationale: Solution: (98.6 - 32) × 5/9 = 37°C. Answer: 37°C.
Question 4 of 5
The nurse is preparing to assess the blood pressure of a 3-year-old. How should the nurse proceed?
Correct Answer: A
Rationale: Explain the procedure to the child: Explaining procedures in an age-appropriate manner helps reduce anxiety and increases cooperation. A 3-year-old can understand simple instructions, so explaining what will happen can help them remain calm. Choose the cuff that says 'Child' instead of 'Infant': Blood pressure cuffs should be appropriately sized for accurate readings. A cuff that is too small can result in falsely high readings, while a cuff that is too large can produce falsely low readings. Use the diaphragm portion of the stethoscope to detect Korotkoff sounds: The bell of the stethoscope is best for detecting low-pitched sounds, including Korotkoff sounds. Obtain the reading before the child has a chance to settle down: A child who is upset, crying, or anxious may have an elevated blood pressure reading due to stress. It is best to allow the child to calm down before obtaining an accurate measurement.
Question 5 of 5
Your patient drunk 150 mL of Ice Tea. How many ounces is this?
Correct Answer: 5
Rationale: Solution: 1 ounce = 30 mL, so 150 mL ÷ 30 mL/oz = 5 oz. Answer: 5 ounces.
