1. Which of the following factors may alter the level of consciousness in a patient?

• A. Alcohol
• B. Electrolytes
• C. Infection
• D. All of the above may cause altered level of consciousness

Correct answer: D

Rationale: Various factors can lead to altered levels of consciousness in a patient. Alcohol consumption can depress the central nervous system and cause changes in consciousness. Electrolyte imbalances, such as hyponatremia or hypernatremia, can disrupt brain function and affect consciousness. Infections, especially those affecting the brain like encephalitis, can also lead to alterations in consciousness. Therefore, all of the choices provided - Alcohol, Electrolytes, and Infection - can potentially cause changes in the level of consciousness. Remember the acronym AEIOU-TIPPS to recall common causes of decreased level of consciousness, including Alcohol, Electrolytes, and Infection, among others.

2. 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.

3. A 55-year-old patient admitted with an abrupt onset of jaundice and nausea has abnormal liver function studies, but serologic testing is negative for viral causes of hepatitis. Which question by the nurse is most appropriate?

• A. Is there any history of IV drug use?
• B. Do you use any over-the-counter drugs?
• C. Are you taking corticosteroids for any reason?
• D. Have you recently traveled to a foreign country?

Correct answer: B

Rationale: The most appropriate question for the nurse to ask in this scenario is whether the patient uses any over-the-counter drugs. The patient's symptoms, negative serologic testing for viral hepatitis, and sudden onset of symptoms point towards toxic hepatitis, which can be triggered by commonly used over-the-counter medications like acetaminophen (Tylenol). Asking about IV drug use is relevant for viral hepatitis, not toxic hepatitis. Inquiring about recent travel to a foreign country is more pertinent to potential exposure to infectious agents causing viral hepatitis. Corticosteroid use is not typically associated with the symptoms described in the case.

4. A nurse in the emergency department is observing a 4-year-old child for signs of increased intracranial pressure after a fall from a bicycle, resulting in head trauma. Which of the following signs or symptoms would be cause for concern?

• A. Bulging anterior fontanel
• B. Repeated vomiting
• C. Signs of sleepiness at 10 PM
• D. Inability to read short words from a distance of 18 inches

Correct answer: B

Rationale: Increased intracranial pressure after head trauma can lead to serious complications. Repeated vomiting is a concerning sign as it can indicate stimulation of the vomiting center within the brainstem due to increased pressure. This can be an early indicator of raised intracranial pressure and the need for urgent medical intervention. Bulging anterior fontanel may not be immediately apparent in a 4-year-old child and is more common in infants. Signs of sleepiness at a particular time of day are not specific to increased intracranial pressure. Inability to read short words from a distance of 18 inches may indicate vision problems but is not directly related to intracranial pressure.

5. The clinic nurse reviews the record of an infant and notes that the primary healthcare provider has documented a diagnosis of suspected Hirschsprung's disease. The nurse reviews the assessment findings documented in the record, knowing that which sign most likely led the mother to seek healthcare for the infant?

• A. Diarrhea
• B. Projectile vomiting
• C. Regurgitation of feedings
• D. Foul-smelling, ribbon-like stools

Correct answer: D

Rationale: Hirschsprung's disease, also known as congenital aganglionosis or aganglionic megacolon, is a congenital anomaly characterized by an absence of ganglion cells in the rectum and other areas of the affected intestine. A key clinical manifestation of Hirschsprung's disease is chronic constipation that starts in the first month of life, leading to pellet-like or ribbon-like stools that have a foul smell. Another sign is the delayed passage or absence of meconium stool in the neonatal period. In addition to foul-smelling, ribbon-like stools, bowel obstruction (especially in the neonatal period), abdominal pain and distention, and failure to thrive are also common clinical manifestations of this disorder. Options A, B, and C are not typically associated with Hirschsprung's disease, making them incorrect choices in this scenario.
