The nurse is preparing to administer a first dose of benztropine (Cogentin) to a patient diagnosed with parkinsonism. The nurse would notify the patient’s provider if the patient had a history of which condition?

Irritable bowel disease

Glaucoma

Asthma

Hypertension

Answer and Explanation

The Correct Answer is B

A) Irritable bowel disease: Benztropine is an anticholinergic medication that can reduce gastrointestinal motility, which might exacerbate constipation. However, irritable bowel disease (IBD) is not a contraindication for using benztropine. The drug is more likely to cause concern in conditions where smooth muscle relaxation could worsen symptoms of constipation, but it is not typically withheld due to IBD alone.

B) Glaucoma: Glaucoma, particularly narrow-angle glaucoma, is a contraindication for benztropine use. Benztropine, as an anticholinergic agent, can cause pupil dilation (mydriasis), which can increase intraocular pressure and worsen glaucoma. This is a critical concern for patients with glaucoma, and the healthcare provider should be notified before administering the drug.

C) Asthma: While benztropine can have mild anticholinergic effects that may cause dryness of the respiratory tract, it is not a contraindication for asthma. Beta-agonist inhalers are more commonly prescribed to manage bronchospasm, but the use of benztropine in asthma is not typically harmful unless the patient is experiencing severe respiratory distress. Asthma would not be a primary concern when administering this medication.

D) Hypertension: Benztropine does not directly affect blood pressure in a way that would be a concern for someone with hypertension. While it may cause some mild autonomic changes (like dry mouth or dizziness), hypertension is not a contraindication for the medication. Therefore, there is no specific need to notify the healthcare provider due to a history of hypertension.

Correct Answer is D

Explanation

A) CSF proteins and an angiography: While cerebrospinal fluid (CSF) analysis is a valuable diagnostic tool in multiple sclerosis (MS), angiography is not typically used in diagnosing MS. Angiography is primarily used to assess blood vessels and would not help in diagnosing a neurological condition like MS, which involves the central nervous system's myelin sheath.
B) Serum anti-acetylcholine antibodies and x-rays: Anti-acetylcholine antibodies are more relevant for diagnosing autoimmune conditions such as myasthenia gravis, not multiple sclerosis. Additionally, x-rays are not useful for diagnosing MS, as MS is primarily a disorder of the central nervous system, and x-rays are not effective in visualizing soft tissues or brain lesions associated with MS.
C) Serum albumin and a computed tomography (CT) scan: Serum albumin levels are not relevant for diagnosing MS. A CT scan may be used in some cases to rule out other conditions, but magnetic resonance imaging (MRI) is more sensitive and specific for diagnosing MS. MRI is particularly effective in detecting the plaques or lesions in the brain and spinal cord that are characteristic of MS.
D) Cerebrospinal fluid (CSF) and magnetic resonance imaging (MRI): This is the correct combination of diagnostic tests for multiple sclerosis. CSF analysis can show elevated levels of immunoglobulin G (IgG) and oligoclonal bands, which are common in MS. MRI is the most sensitive imaging tool for detecting the characteristic plaques or demyelinated areas in the brain and spinal cord, which are hallmarks of MS. Therefore, this combination is the gold standard for confirming the diagnosis of MS.

A. Feed cells under tress B. Act on invading organisms C. Control vital functions D. Shut down the body at death

Correct Answer is C

Explanation

A) Feed cells under stress:
The primary function of the homeostasis control systems is not to directly "feed" cells under stress, but to regulate internal balance and ensure all systems are functioning optimally, particularly in response to changes in the environment or internal states. "Feeding" or providing nutrients is a broader metabolic process rather than a direct function of the homeostasis control systems.

B) Act on invading organisms:
While the immune system, which plays a role in defending the body against invading organisms, is a part of overall body regulation, homeostasis itself is more concerned with maintaining internal stability. The control systems of the body regulate physiological processes such as temperature, pH, and fluid balance rather than directly targeting external organisms like bacteria or viruses, which would fall under the immune response.

C) Control vital functions:
Homeostasis control systems are integral in maintaining the body's internal environment, ensuring stability for vital functions such as temperature, heart rate, blood pressure, and respiratory rate. These systems help adjust these functions in response to various internal and external stimuli to maintain optimal conditions for survival, making this the most accurate answer.

D) Shut down the body at death:
While the control systems ultimately cease to function at death, the purpose of homeostasis during life is to maintain the balance of bodily functions, not to cause the cessation of life. The homeostatic mechanisms are about maintaining life and health, preventing "shutdown" until the point of death.
