The nurse is caring for a client receiving treatment for myxedema. The nurse should explain that warm blankets are used to warm the client instead of heating pads for which of the following reasons?

Active rewarming may increase oxygen demands.

Electric cords from heating pads can be a choking hazard.

Heating pads could cause tissue burns.

Warm blankets are more comforting for the client.

Answer and Explanation

The Correct Answer is C

A. The statement active rewarming may increase oxygen demands is true for some conditions, like hypothermia, but it is not the primary reason to avoid heating pads for a client with myxedema. While rewarming can increase oxygen demands, the primary concern with heating pads is the risk of burns due to impaired thermoregulation in myxedema.
B. This is not relevant to the scenario. The concern with heating pads is not about choking hazards but about burns and safe rewarming.
C. In myxedema, the body’s ability to regulate temperature and respond to thermal stimuli is impaired due to severe hypothyroidism. This puts the client at a higher risk for burns if heating pads are used. Using warm blankets instead of heating pads ensures a safer, more gradual rewarming process.
D. While warm blankets may indeed be more comforting, the primary reason for using them instead of heating pads is to avoid the risk of burns due to impaired temperature regulation.

Correct Answer is D

Explanation

A. Carbidopa does not directly prevent dyskinesia. Dyskinesia is often a side effect of long-term levodopa therapy. Carbidopa’s role is to help optimize the effectiveness of levodopa and reduce side effects, but it does not specifically prevent dyskinesia.
B. The combination of levodopa and carbidopa does not prevent drug tolerance. Drug tolerance refers to the reduced effect of a drug over time, and while the combination may help with optimal absorption and effectiveness, it doesn't directly address tolerance.
C. While carbidopa helps reduce some side effects (such as nausea and vomiting) by preventing the peripheral breakdown of levodopa, the primary purpose of combining the two drugs is not solely to prevent side effects but to improve levodopa's effectiveness and absorption in the brain.
D. Carbidopa inhibits the enzyme aromatic L-amino acid decarboxylase (AADC) in the peripheral tissues, preventing the premature breakdown (metabolism) of levodopa into dopamine before it reaches the brain. This allows more levodopa to enter the brain and be converted into dopamine, enhancing the therapeutic effect for Parkinson's disease.

A. Because an acute condition has caused the seizures you have had. B. When a client has had a seizure that has lasted more than 5 minutes. C. When a client has a history of 2 or more seizures more than 24 hours apart. D. Because there is no known cause for the seizures you have had

Correct Answer is C

Explanation

A. Epilepsy is a chronic neurological disorder characterized by recurrent, unprovoked seizures, and an acute condition is not typically the cause of seizures in people with epilepsy.
B. While a seizure lasting more than 5 minutes (status epilepticus) is a medical emergency, it does not define epilepsy. Epilepsy is diagnosed based on recurrent, unprovoked seizures, not the duration of a single seizure.
C. Epilepsy is diagnosed when a person has had two or more unprovoked seizures that occur more than 24 hours apart. This is the key criterion for the diagnosis of epilepsy, which is a chronic condition.
D. While it's true that some forms of epilepsy may not have a known cause, many cases of epilepsy have identifiable causes, such as brain injury, genetic factors, or structural abnormalities. The diagnosis of epilepsy is not solely based on the absence of a known cause for seizures.
