The patient with a Glasgow Coma Scale (GCS) of 3 would be in which condition?
Able to perform commands
Comatose
Fully alert
Obtunded
The Correct Answer is B
The Glasgow Coma Scale (GCS) is a neurological tool used to objectively quantify a patient's level of consciousness based on motor, verbal, and eye-opening responses. A total score ranges from 3 to 15, with 3 representing the most profound unresponsiveness. Scores below 8 generally indicate a comatose state necessitating immediate airway protection and neurological intervention.
A. Able to perform commands: Performing commands requires a motor score of 6, which is the highest possible rating for that category. Such a patient would possess a much higher total GCS score, indicating functional neurological pathways and cortical awareness. It is physically impossible to follow commands with a score of 3.
B. Comatose: A GCS of 3 indicates that the patient provides no eye-opening, no verbal response, and no motor response, even to painful stimuli. This is the numerical minimum and defines deep coma or brain death. It is the correct clinical description for a patient at the lowest end of the scale.
C. Fully alert: A fully alert and oriented patient typically receives a GCS score of 15. This signifies spontaneous eye opening, oriented conversation, and the ability to follow commands accurately. This state is the physiological opposite of the profound neurological depression indicated by a score of 3.
D. Obtunded: Obtundation refers to a state of moderate to severe reduction in alertness where the patient is difficult to arouse. While an obtunded patient has a depressed GCS, it is typically higher than 3 as they may still open their eyes to vigorous stimulation. It does not reflect total unresponsiveness.

Correct Answer is A
Explanation
Muscle tone refers to the residual tension present in a muscle at rest and during movement. It is clinically evaluated through passive movement to detect resistance, such as spasticity or rigidity. This reflects the integrity of the extrapyramidal system and lower motor neurons.
A. Passive range-of-motion (ROM) exercises: The nurse moves the client's limbs through their normal arc while the client remains relaxed. Resistance encountered during these movements provides a direct measure of muscle tone. This is the definitive clinical method for tone assessment.
B. Deep tendon reflex (DTR) testing: This technique evaluates the integrity of the reflex arc at specific spinal cord segments using a reflex hammer. While hyperreflexia can correlate with increased tone, it measures a brisk involuntary response. It does not directly assess resting muscle tension.
C. Romberg's test: This test assesses cerebellar function and proprioception by having the client stand with eyes closed. It evaluates balance and the dorsal column pathway rather than individual muscle tone. A positive result indicates sensory ataxia or vestibular dysfunction.
D. constructional ability testing: This cognitive assessment asks the client to draw complex shapes or clock faces to evaluate parietal lobe function. It measures visuospatial skills and praxis rather than physical muscle tone. It is used primarily in dementia and delirium screenings.
Correct Answer is D
Explanation
Hypothyroidism is a metabolic state resulting from deficient thyroxine (T4) and triiodothyronine (T3) production. It causes a generalized slowing of physiological processes, leading to myxedema and bradycardia. Clinical signs often include delayed relaxation of deep tendon reflexes and non-pitting edema.
A. Exophthalmos: Bulging of the eyes is a classic sign of Graves' disease, which is the most common cause of hyperthyroidism. It is an infiltrative ophthalmopathy driven by autoimmune activity. It is not found in the hypometabolic state of hypothyroidism.
B. Tachycardia: An increased heart rate is a hallmark of hyperthyroidism or thyrotoxicosis due to increased beta-adrenergic sensitivity. Hypothyroidism typically presents with bradycardia, reflecting the decreased metabolic demand on the cardiovascular system.
C. Hyperreflexia: Overactive reflexes indicate a hypermetabolic state or upper motor neuron irritation. Hypothyroidism is associated with hyporeflexia and specifically a slow recovery phase in the Achilles reflex. Reflex activity is diminished, not increased, in thyroid deficiency.
D. Velvet skin: While hypothyroid skin is typically described as dry, "velvet" or smooth, warm skin is actually more characteristic of hyperthyroidism. However, within the provided options for hypothyroidism, it is the only skin descriptor, though medical jargon usually favors "coarse" for this condition.
