Question 1 of 5
The nurse is aware that multiple sclerosis is a progressive disease of the central nervous system characterized by:
Correct Answer: D
Rationale: Multiple sclerosis (MS) is a progressive disease of the central nervous system characterized by all the given options: axon degeneration, sclerosed patches of the nervous system, and demyelination of the brain and spinal cord. Axon degeneration occurs due to the damage caused by the immune system attacking the myelin sheath. Sclerosed patches of the nervous system result from the formation of scar tissue in the central nervous system. Demyelination is the hallmark feature of MS, where the protective covering of nerve fibers (myelin) is damaged, leading to disrupted communication between the brain and the rest of the body. Collectively, these characteristics contribute to the clinical manifestations and progression of multiple sclerosis.
Question 2 of 5
The physician orders propranolol (Inderal) for a client's angina. The effect of this drug is to:
Correct Answer: B
Rationale: Propranolol (Inderal) is a beta-blocker medication that works by blocking beta stimulation in the heart. By doing so, it reduces the workload on the heart and helps to decrease the heart rate and blood pressure. This is beneficial in the management of angina because it decreases the oxygen demand of the heart muscle, thereby relieving chest pain. Propranolol does not act as a vasoconstrictor, vasodilator, or increase the heart rate.
Question 3 of 5
Usually, how does the patient behave after his seizure has subsided?
Correct Answer: C
Rationale: After a seizure has subsided, it is common for the patient to experience restlessness and agitation. This may be due to confusion, disorientation, and fatigue following the seizure. Restlessness and agitation can also be caused by the brain's recovery process and the emotional impact of a seizure episode. It is important to provide a calm and supportive environment for the patient during this time and to ensure their safety until they fully recover from the seizure.
Question 4 of 5
A client has cancer that has me tastasized to her bones. She is complaining of increased thirst, polyuria and decreased muscle tone. Her lab values are: Na 139mEq/L, k 4 mEq/L, Cl 103 mEq/L, and Ca 8 mg/dl. What electrolyte imbalance is present?
Correct Answer: C
Rationale: The patient's symptoms of increased thirst, polyuria, decreased muscle tone, and the lab value of high calcium (8 mg/dl) indicate hypercalcemia. Hypercalcemia is commonly seen in cancer patients due to cancer metastasis to the bones, leading to the release of calcium. The other electrolyte levels (sodium, potassium, and chloride) are within normal range, ruling out other electrolyte imbalances. Multiple myeloma is a common malignancy associated with bone metastases and hypercalcemia. Symptoms of hypercalcemia may include thirst, frequent urination, weakness, confusion, and muscle pain. Treatment of hypercalcemia may involve hydration, loop diuretics, bisphosphonates, and addressing the underlying cause.
Question 5 of 5
A surgical intervention that can cause substantial remission of myasthenia gravis is:
Correct Answer: B
Rationale: Thymectomy is a surgical procedure that involves the removal of the thymus gland. The thymus is a key component of the immune system and is believed to play a role in the development of myasthenia gravis (MG). In some cases, particularly in younger patients with early onset MG or with thymoma (a tumor of the thymus), thymectomy can lead to substantial remission of MG symptoms or even a cure. By removing the thymus gland, the abnormal immune response in MG may be reduced, resulting in improved muscle strength and decreased symptoms. It is worth noting that thymectomy is not always indicated for all patients with MG and should be considered on a case-by-case basis in consultation with a healthcare provider specialized in neuromuscular diseases.
