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.

Correct Answer: D

Rationale: Hypotension is not a typical sign or symptom of an acute stroke. The correct signs and symptoms of a stroke include sudden weakness or numbness of the face, arm, or leg, sudden confusion, and a sudden headache with no known cause. Hypotension, which refers to low blood pressure, is not a common indicator of a stroke. It is important to differentiate between hypotension and hypertension in the context of stroke symptoms, as hypertension (high blood pressure) is actually a risk factor for strokes. Sudden weakness, numbness, confusion, and headache are signs associated with a stroke due to a disruption in blood flow to the brain. Hypotension, on the other hand, primarily indicates low blood pressure and is not directly linked to the typical presentation of a stroke.

Correct Answer: B

Rationale: When encountering a 16-month-old child exhibiting fear of strangers by clinging to the parent and crying, it is essential for the nurse to explain that this behavior is expected. Fear of strangers typically emerges around 6-8 months of age and can continue into the toddler years and beyond. This behavior is a normal part of development as the child is displaying attachment and trust in familiar caregivers. Changing client care assignments, discussing 'time-out,' or suggesting the child needs extra attention are not appropriate initial actions in this situation. Changing care assignments is unnecessary and does not address the child's emotional needs. Discussing 'time-out' is not relevant as it pertains to discipline strategies for older children. Suggesting the child needs extra attention may misinterpret the situation; the child's behavior is a normal response to a new environment and does not necessarily indicate a need for additional attention.

Correct Answer: B

Rationale: Elevated serum ALT levels would further confirm the diagnosis of Hepatitis. ALT is a liver enzyme, and hepatitis is a liver disease. Elevated liver enzymes, such as ALT, often indicate liver damage. Choice A, 'Decreased serum Bilirubin,' is incorrect as elevated bilirubin levels are typically seen in hepatitis due to impaired bilirubin metabolism. Choices C and D are unrelated to confirming a diagnosis of hepatitis as they describe findings not specific to liver function or hepatitis. Low RBC and Hemoglobin with increased WBCs (Choice C) suggest a different condition like anemia or infection, not specific to liver disease. Increased Blood Urea Nitrogen level (Choice D) is more indicative of kidney function rather than liver function, thus not helpful in confirming hepatitis.

Correct Answer: D

Rationale: In a patient in shock, increasing blood pressure is not a sign that compensatory mechanisms are failing. As shock progresses and compensatory mechanisms fail, systolic blood pressure will decrease, leading to hypotension, which is a late and ominous sign in these patients. Therefore, choices A, B, and C are warning signs of failing compensatory mechanisms in shock: an increasing heart rate above normal, absent peripheral pulses, and decreasing level of consciousness, respectively. An increasing blood pressure is not indicative of compensatory failure in shock; instead, it may be a sign of compensatory mechanisms still trying to maintain perfusion pressure.
