Question 1 of 5
Clinical manifestations of Huntington’s disease include:
Correct Answer: D
Rationale: The correct answer is D because Huntington's disease is a neurodegenerative disorder that presents with a triad of symptoms: abnormal involuntary movements (chorea), intellectual decline, and emotional disturbances. Abnormal involuntary movements are a hallmark feature, while cognitive decline and emotional disturbances are also commonly observed. Therefore, all three manifestations are typically present in individuals with Huntington's disease. Choices A, B, and C are incorrect because each of these symptoms alone does not encompass the full spectrum of clinical manifestations seen in Huntington's disease.
Question 2 of 5
What deficits would the nurse expect in a right-handed person experiencing a stroke affecting the left side of the cortex?
Correct Answer: A
Rationale: The correct answer is A: Expressive aphasia and paralysis on the right side of the body. In a right-handed person, the left side of the brain controls language and right-sided motor function. A stroke affecting the left side of the cortex would lead to expressive aphasia due to damage to Broca's area, causing difficulty in speaking and forming words. Paralysis on the right side of the body would result from damage to the motor cortex in the left hemisphere. Choices B, C, and D are incorrect because they do not align with the typical deficits seen in a person with a stroke affecting the left side of the cortex in a right-handed individual.
Question 3 of 5
Which of the following parts of neuron transmits impulses away from the cell body?
Correct Answer: C
Rationale: The correct answer is C: Axon. The axon is the part of the neuron that transmits impulses away from the cell body towards other neurons or target cells. It is coated with a myelin sheath, which helps speed up the transmission of impulses. Dendrites (A) receive signals from other neurons, the neurolemma (B) is the outermost layer of the myelin sheath, and the synapse (D) is the junction between two neurons where neurotransmitters are released. Therefore, the axon is the only part of the neuron specifically responsible for transmitting impulses away from the cell body.
Question 4 of 5
Which drug class is used to reduce symptoms of muscle weakness from myasthenia gravis?
Correct Answer: A
Rationale: The correct answer is A: Anticholinesterase drugs. These drugs increase acetylcholine levels at neuromuscular junctions, helping improve muscle strength in myasthenia gravis. Adrenergic drugs (B) and beta-blocker drugs (D) are not typically used to treat muscle weakness in myasthenia gravis. Anticholinergic drugs (C) can worsen symptoms by blocking acetylcholine receptors, making them an inappropriate choice for this condition.
Question 5 of 5
Which of the ff nursing interventions may reduce hemostasis and decrease the potential for thrombophlebitis for a client with a neurologic disorder?
Correct Answer: B
Rationale: The correct answer is B: Keep extremities at neutral position. This intervention promotes proper blood flow and reduces the risk of thrombophlebitis by preventing compression or restriction of blood vessels. Removing and reapplying elastic stockings (choice A) can disrupt circulation and increase the risk of thrombophlebitis. Changing the client's position (choice C) may not directly address hemostasis or thrombophlebitis. Using a flotation mattress (choice D) is not specifically focused on maintaining proper positioning of the extremities to promote circulation.
