A patient with Parkinson's disease asks the nurse why anticholinergics are used in the treatment. Which response by the nurse is most accurate?

"These drugs inhibit the action of acetylcholine

"These drugs help you urinate."

"These drugs will decrease your eye pressure."

"These drugs will assist in lowering your heart rate."

Answer and Explanation

The Correct Answer is A

A. "These drugs inhibit the action of acetylcholine":

This response is accurate. Anticholinergic medications work by blocking the action of acetylcholine, a neurotransmitter involved in various functions in the body, including muscle control. In Parkinson's disease, there is an imbalance between dopamine and acetylcholine, leading to motor symptoms such as tremors and rigidity. By inhibiting the action of acetylcholine, anticholinergic drugs help rebalance neurotransmitter activity and alleviate some of the motor symptoms associated with Parkinson's disease.

B. "These drugs help you urinate":

This statement is not directly related to the use of anticholinergic medications in Parkinson's disease. While some anticholinergic drugs can indeed relax the smooth muscle of the bladder and improve urinary symptoms, this is not the primary indication for their use in Parkinson's disease.

C. "These drugs will decrease your eye pressure":

While anticholinergic medications can be used to dilate the pupils and decrease intraocular pressure, this is not typically the reason for their use in Parkinson's disease. While some anticholinergic medications may have ocular effects, they are primarily used to address motor symptoms associated with Parkinson's disease.

D. "These drugs will assist in lowering your heart rate":

While some anticholinergic medications may have effects on heart rate by blocking parasympathetic nervous system activity, this is not the primary indication for their use in Parkinson's disease. The focus of anticholinergic therapy in Parkinson's disease is primarily on addressing motor symptoms rather than cardiovascular effects.

Correct Answer is A

Explanation

A.Computerized tomography angiography (CTA)

This is a likely diagnostic test that the provider may prescribe. CTA uses computed tomography (CT) imaging to visualize the blood vessels in the brain and neck. It can help identify areas of stenosis, occlusion, or other abnormalities in the blood vessels that may contribute to the TIA symptoms.

B. Complete blood count (CBC)

A complete blood count (CBC) is a routine laboratory test that assesses various components of blood, such as red blood cells, white blood cells, and platelets. While it may not be specific to diagnosing a transient ischemic attack (TIA), it can help evaluate for underlying conditions such as anemia or thrombocytosis that could contribute to TIA symptoms or increase the risk of stroke.

C. Prothrombin time (PT)

Prothrombin time (PT) is a laboratory test that evaluates the clotting ability of blood and is typically used to monitor anticoagulant therapy. While abnormal coagulation parameters may be associated with certain conditions that predispose to TIA (such as atrial fibrillation), PT alone is not a specific diagnostic test for TIA.

D. Transesophageal echocardiogram (TEE)

This is another possible diagnostic test that the provider may prescribe. TEE is a specialized echocardiogram that provides detailed images of the heart structures by inserting an ultrasound probe

A. Aura phase B. Presence of automatisms C. Postictal phase D. Presence of absence seizures

Correct Answer is C

Explanation

A. Aura phase:

The aura phase occurs before the seizure and is characterized by subjective sensations or experiences that some individuals may have. It serves as a warning sign that a seizure is about to occur. This phase precedes the seizure itself and is not applicable to the period immediately afterward.

B. Presence of automatisms:

Automatisms refer to repetitive, involuntary movements or actions that some individuals may exhibit during certain types of seizures, such as complex partial seizures. They are not typically observed during the postictal phase of a generalized tonic-clonic seizure.

C. Postictal phase:

The postictal phase, also known as the postictal state, refers to the period following a seizure during which the individual may experience confusion, drowsiness, or other altered states of consciousness. This phase typically lasts for minutes to hours and is characterized by gradual recovery of normal function.

D. Presence of absence seizures:

Absence seizures are characterized by brief episodes of altered consciousness, often manifesting as staring spells or momentary loss of awareness. They are distinct from generalized tonic-clonic seizures and do not involve the same postictal phase characterized by drowsiness and altered arousal.
