1. Which of the following can cause coup-contrecoup injuries?

• A. Rotational forces
• B. Deformation forces
• C. Deceleration forces
• D. Acceleration forces

Correct answer: C

Rationale: Deceleration forces occur when the head is moving and abruptly comes to a stop, such as in a car crash. This sudden deceleration can cause the brain to hit against the skull, resulting in coup-contrecoup injuries. In a coup-contrecoup injury, the brain is damaged on opposite sides due to the initial impact and the rebound effect inside the skull. Rotational forces usually result in diffuse axonal injuries rather than coup-contrecoup injuries. Deformation forces can cause focal brain injuries but not coup-contrecoup injuries. Acceleration forces typically lead to diffuse brain injuries, not coup-contrecoup injuries. Therefore, the correct answer is deceleration forces.

2. Which of the following signs is NOT indicative of increased intracranial pressure?

• A. Decreased level of consciousness
• B. Projectile vomiting
• C. Sluggish pupil dilation
• D. Increased heart rate

Correct answer: D

Rationale: Increased intracranial pressure can lead to serious complications if not promptly addressed. Common signs of increased intracranial pressure include decreased level of consciousness, sluggish pupil dilation, abnormal respirations, and projectile vomiting. However, an increased heart rate is not a typical sign associated with increased intracranial pressure. It is important for healthcare providers to recognize these signs early to prevent severe consequences such as brain herniation.

3. A mother has recently been informed that her child has Down syndrome. You will be assigned to care for the child at shift change. Which of the following characteristics is not associated with Down syndrome?

• A. Simian crease
• B. Brachycephaly
• C. Oily skin
• D. Hypotonicity

Correct answer: C

Rationale: Individuals with Down syndrome commonly have certain physical characteristics, such as a simian crease (single transverse palmar crease), brachycephaly (shortened front-to-back skull dimension), and hypotonicity (low muscle tone). Oily skin is not a characteristic associated with Down syndrome; instead, individuals with Down syndrome often have dry skin. Therefore, oily skin is the correct answer in this context.

4. A fragile 87-year-old female has recently been admitted to the hospital with increased confusion and falls over the last two weeks. She is also noted to have a mild left hemiparesis. Which of the following tests is most likely to be performed?

• A. CBC (Complete Blood Count)
• B. ECG (Electrocardiogram)
• C. Thyroid Function Tests
• D. CT Scan

Correct answer: D

Rationale: A CT scan is most likely to be performed in this scenario. A CT scan would be done to further investigate the cause of the left hemiparesis. Noncontrast CT scanning is commonly used in the acute evaluation of patients with suspected acute stroke to assess for ischemic changes or hemorrhage in the brain. While a CBC may provide information on blood cell counts and general health status, it is not the primary test for evaluating hemiparesis. An ECG is used to assess heart function and rhythm, which is not the main concern in this case. Thyroid function tests evaluate thyroid hormone levels and are not typically the initial tests for evaluating hemiparesis and confusion.

5. A patient who has a right-sided chest tube following a thoracotomy has continuous bubbling in the suction-control chamber of the collection device. Which action by the nurse is most appropriate?

• A. Document the presence of continuous bubbling.
• B. Notify the surgeon of a possible pneumothorax.
• C. Take no further action with the collection device.
• D. Adjust the dial on the wall regulator to decrease suction.

Correct answer: C

Rationale: Continuous bubbling in the suction-control chamber of the chest tube collection device is an expected finding and indicates that the suction control chamber is connected to suction. It does not necessarily indicate a large air leak, which would be detected in the water-seal chamber. There is no evidence to suggest a pneumothorax based solely on continuous bubbling in the suction-control chamber. Adjusting the suction level by changing the wall regulator setting is not indicated in this situation, as the amount of suction applied is primarily regulated by the water level in the water-seal chamber and not by the vacuum source. Therefore, the most appropriate action in this scenario is for the nurse to take no further action with the collection device.
