1. Which of the following eye disorders manifests with red eye, pain, and visual acuity changes?

• A. Bacterial conjunctivitis
• B. Acute closed-angle glaucoma
• C. Chronic open-angle glaucoma
• D. Blepharitis

Correct answer: B

Rationale: Acute closed-angle glaucoma presents with symptoms such as a red eye, severe pain, and rapid visual acuity changes due to increased intraocular pressure. This condition is considered an ophthalmologic emergency. Bacterial conjunctivitis typically presents with redness, discharge, and irritation but is not associated with severe pain or visual changes. Chronic open-angle glaucoma is usually asymptomatic until advanced stages and does not typically present with acute pain. Blepharitis involves inflammation of the eyelid margins and is characterized by redness and irritation, but it does not cause severe pain or acute visual changes.

2. What is the best method to identify which type of stroke the client has?

• A. Obtain a 12-lead electrocardiogram STAT
• B. Obtain a blood specimen for electrolytes and blood cultures
• C. Ask the client about current allergies
• D. Obtain a cranial computerized tomogram (CT) STAT

Correct answer: D

Rationale: The correct answer is to obtain a cranial computerized tomogram (CT) STAT. A cranial CT scan is the best method to quickly identify the type of stroke a client is experiencing. Options A, B, and C are not appropriate for identifying the type of stroke as they are not specific to assessing stroke types.

3. A client with a diagnosis of depression has been prescribed a medication that ultimately increases the levels of the neurotransmitter serotonin between neurons. Which process will accompany the actions of the neurotransmitter in a chemical synapse?

• A. Two-way communication between neurons is permitted, in contrast to the one-way communication in electrical synapses.
• B. Communication between a neuron and the single neuron it is connected with will be facilitated.
• C. The neurotransmitter will cross gap junctions more readily.
• D. More neurotransmitters will cross the synaptic cleft and bond with postsynaptic receptors.

Correct answer: D

Rationale: When serotonin levels increase, more neurotransmitters will cross the synaptic cleft and bind with postsynaptic receptors, facilitating enhanced communication. Option A is incorrect because chemical synapses, unlike electrical synapses, are unidirectional. Option B is incorrect because neurotransmitters impact communication with multiple neurons, not just a single connected neuron. Option C is incorrect because neurotransmitters cross the synaptic cleft, not gap junctions.

4. A client has experienced a pontine stroke which has resulted in severe hemiparesis. What priority assessment should the nurse perform prior to allowing the client to eat or drink from the food tray?

• A. Evaluate the client's gag reflex.
• B. Assess the client's bowel sounds.
• C. Check the client's pupil reaction.
• D. Monitor the client's heart rate.

Correct answer: A

Rationale: The correct answer is to evaluate the client's gag reflex. When a client has experienced a stroke resulting in severe hemiparesis, assessing the gag reflex is crucial before allowing them to eat or drink. This assessment helps prevent aspiration, a serious complication that can occur due to impaired swallowing ability. Assessing bowel sounds (Choice B), pupil reaction (Choice C), or heart rate (Choice D) are important assessments but are not the priority in this situation where the risk of aspiration is higher.

5. During an assessment of a male client suspected of having a disorder of motor function, which finding would suggest a possible upper motor neuron (UMN) lesion?

• A. Hypotonia
• B. Hyperreflexia
• C. Muscle atrophy
• D. Fasciculations

Correct answer: B

Rationale: Hyperreflexia, or exaggerated reflexes, is a common sign of an upper motor neuron (UMN) lesion. An UMN lesion indicates damage to the central nervous system pathways that control movement. Hypotonia (choice A) refers to reduced muscle tone, which is more indicative of lower motor neuron lesions. Muscle atrophy (choice C) suggests long-standing denervation or disuse of muscles. Fasciculations (choice D) are involuntary muscle contractions that can be seen in lower motor neuron lesions, like in amyotrophic lateral sclerosis (ALS), rather than UMN lesions.
