Initial treatment of the patient with a fracture should include
- A. Surgical reduction of the fracture.
- B. Insertion of internal fixation device.
- C. Reduction of the fracture.
- D. Immobilization of the area.
Correct Answer: D
Rationale: Immobilization is often the first step in managing fractures to prevent further injury.

The resting membrane potential of a cell
- A. is dependent on the permeability of the cell membrane to K+ being greater than the permeability to Na+
- B. falls to zero immediately when Na+, K+ ATPase in the membrane is inhibited
- C. is usually equal to the equilibrium potential for K+
- D. is usually equal to the equilibrium potential for Na+
Correct Answer: A
Rationale: The resting membrane potential is primarily determined by the permeability of the cell membrane to potassium ions (K+), which is greater than its permeability to sodium ions (Na+). This is because the membrane has more leak channels for K+ than for Na+, allowing K+ to diffuse out of the cell, creating a negative intracellular environment. The Na+, K+ ATPase pump maintains this gradient but does not directly set the resting potential. Inhibition of the pump would eventually disrupt the gradient, but the potential does not immediately fall to zero.
Neurotransmitters carry signals across the ________ ________.
- A. refractory gap
- B. axonal gap
- C. synaptic gap
- D. hippocampal gap
Correct Answer: C
Rationale: Neurotransmitters carry signals across the synaptic gap, also known as the synaptic cleft, which is the small space between the terminal button of one neuron and the dendrite of another. When an action potential reaches the terminal button, neurotransmitters are released into the synaptic gap and bind to receptors on the postsynaptic neuron, facilitating communication between neurons. This process is essential for neural signaling and brain function.
Before feeding a patient four days following a stroke, what should the nurse do first?
- A. Check the patient's gag reflex.
- B. Order a soft diet for the patient.
- C. Raise the head of the bed to a sitting position.
- D. Evaluate the patient's ability to swallow small amounts of crushed ice or ice water.
Correct Answer: A
Rationale: Checking the gag reflex ensures the patient can safely swallow and reduces the risk of aspiration
The afferent path of the sneeze reflex is mediated via the
- A. Ophthalmic nerve V1
- B. Maxillary nerve V2
- C. Mandibular nerve V3
- D. Vagus nerve
Correct Answer: B
Rationale: The sneeze reflex is triggered by irritation of the nasal mucosa, which is innervated by the maxillary nerve (V2). The reflex involves the trigeminal nerve and medullary centers.
The presence of Laseuge sign suggests damage to the following:
- A. meninges of the brain
- B. spinal roots C5-C8 or radial nerve
- C. spinal roots L5-S1 or sciatic nerve
- D. anterior horns at the level L5-S1
Correct Answer: C
Rationale: Spinal roots L5-S1 or sciatic nerve is the correct answer because Lasegue's sign, also known as the straight leg raise test, is used to diagnose sciatica or lumbar radiculopathy. Pain elicited during this test indicates irritation or compression of the sciatic nerve or its roots, typically due to a herniated disc.
