1. A patient has been diagnosed with prostatitis and is being seen at the clinic for symptoms of burning and pain during urination. What is he experiencing?
-
Dysuria
-
Nocturia
-
Hematuria
-
Polyuria
Explanation
Explanation
Correct Answer Is:
A. Dysuria
Dysuria refers to painful or burning urination. It is a common symptom of prostatitis, urinary tract infections, and other genitourinary conditions. The patient's description of burning and pain specifically during urination is the classic definition of dysuria.
Why the other options are incorrect:
B. Nocturia refers to waking up at night to urinate, not burning or pain during urination.
C. Hematuria refers to blood in the urine, which is not what the patient is describing.
D. Polyuria refers to abnormally large volumes of urine production, not painful or burning urination.
Correct Answer Is:

Why the other options are incorrect:
B. Nocturia refers to waking up at night to urinate, not burning or pain during urination.
C. Hematuria refers to blood in the urine, which is not what the patient is describing.
D. Polyuria refers to abnormally large volumes of urine production, not painful or burning urination.
2. What type of lymph node would most likely be enlarged in a patient with a recent breast infection?
-
Contralateral central axillary
-
Ipsilateral central axillary
-
Ipsilateral inguinal
-
Contralateral inguinal
Explanation
Explanation
Correct Answer Is:
B. Ipsilateral central axillary
The lymphatic drainage of the breast flows primarily to the axillary lymph nodes on the same side (ipsilateral) as the affected breast. The central axillary nodes are the main group receiving drainage from the breast. In the presence of infection, these nodes become enlarged as they filter pathogens and mount an immune response.
Why the other options are incorrect:
A. Contralateral axillary nodes are on the opposite side of the body from the infection and would not typically be the primary drainage site for a breast infection.
C. Ipsilateral inguinal nodes drain the lower extremities and perineal region, not the breast.
D. Contralateral inguinal nodes drain the opposite lower extremity and would have no connection to a breast infection.
Correct Answer Is:
B. Ipsilateral central axillary
The lymphatic drainage of the breast flows primarily to the axillary lymph nodes on the same side (ipsilateral) as the affected breast. The central axillary nodes are the main group receiving drainage from the breast. In the presence of infection, these nodes become enlarged as they filter pathogens and mount an immune response.
Why the other options are incorrect:
A. Contralateral axillary nodes are on the opposite side of the body from the infection and would not typically be the primary drainage site for a breast infection.

D. Contralateral inguinal nodes drain the opposite lower extremity and would have no connection to a breast infection.
3. A patient is visiting the clinic because of "pain in my bottom when I have a bowel movement." What problem would the nurse assess for?
-
Colon cancer
-
Hemorrhoids
-
Fecal incontinence
-
Pinworms
Explanation
Explanation
Correct Answer: B. Hemorrhoids
Hemorrhoids are swollen veins in the rectum or anus that commonly cause pain, discomfort, and sometimes bleeding during bowel movements. Pain specifically occurring during defecation is the classic presenting symptom of hemorrhoids, making this the most likely condition to assess for.
Why Other Options are Incorrect:
A. Colon cancer typically presents with changes in bowel habits, blood in stool, and unexplained weight loss, not specifically pain during bowel movements. C. Fecal incontinence refers to the inability to control bowel movements, not pain during defecation. D. Pinworms typically cause perianal itching, especially at night, not pain specifically during bowel movements.
Correct Answer: B. Hemorrhoids
Hemorrhoids are swollen veins in the rectum or anus that commonly cause pain, discomfort, and sometimes bleeding during bowel movements. Pain specifically occurring during defecation is the classic presenting symptom of hemorrhoids, making this the most likely condition to assess for.
Why Other Options are Incorrect:
A. Colon cancer typically presents with changes in bowel habits, blood in stool, and unexplained weight loss, not specifically pain during bowel movements. C. Fecal incontinence refers to the inability to control bowel movements, not pain during defecation. D. Pinworms typically cause perianal itching, especially at night, not pain specifically during bowel movements.
4. A patient states that they seem to have to urinate suddenly and "wets myself a little" on the way to the bathroom. What is the patient experiencing?
-
True urinary incontinence
-
Urge incontinence
-
Stress incontinence
-
Hematuria
Explanation
Explanation
Correct Answer Is:
B. Urge incontinence
Urge incontinence is characterized by a sudden, intense urge to urinate followed by involuntary leakage of urine before reaching the bathroom. This is caused by overactive bladder contractions and is exactly what the patient is describing with the sudden urge and leaking on the way to the restroom.
Why the other options are incorrect:
A. True urinary incontinence refers to continuous, uncontrollable leakage of urine without any sensation or urge, which is not what this patient describes.
C. Stress incontinence involves leakage of small amounts of urine triggered by physical activity, coughing, sneezing, or laughing that increases abdominal pressure, not a sudden urge.
D. Hematuria refers to blood in the urine and is not a type of incontinence, nor does it describe the patient's symptoms.
Correct Answer Is:
B. Urge incontinence

5. Which area of the brain is most closely associated with feeling unsteady and difficulty maintaining balance?
-
Brain stem
-
Thalamus
-
Cerebellum
-
Extrapyramidal tract
Explanation
Explanation
Correct Answer: C. Cerebellum
The cerebellum is the primary brain structure responsible for coordinating movement, balance, and posture. Damage to or dysfunction of the cerebellum results in ataxia, unsteadiness, and difficulty maintaining balance, which are hallmark signs of cerebellar disorders.
Why Other Options are Incorrect:
A. The brain stem controls vital functions such as breathing, heart rate, and consciousness, as well as serving as a pathway for motor and sensory signals, but is not primarily responsible for balance coordination. B. The thalamus acts as a relay station for sensory and motor signals between the body and the cerebral cortex but does not directly coordinate balance. D. The extrapyramidal tract is involved in regulating muscle tone and involuntary movements, but balance coordination is primarily a cerebellar function.

6. What would be used to assess light touch on a patient's extremities?
-
Tuning fork
-
Reflex hammer
-
Tongue blade
-
Wisp of cotton
Explanation
Explanation
Correct Answer: D. Wisp of cotton
A wisp of cotton is the standard tool used to assess light touch sensation on a patient's extremities during a neurological examination. It is gently applied to the skin without pressure to test the integrity of sensory nerve pathways.
Why Other Options are Incorrect:
A. A tuning fork is used to assess vibratory sensation and hearing (cranial nerve VIII), not light touch. B. A reflex hammer is used to test deep tendon reflexes, not light touch sensation. C. A tongue blade is used to assess the gag reflex and oral cavity, not light touch on extremities.

7. When the nurse asks a patient to stand with feet together, arms at the side, and with eyes closed, the patient starts to sway and moves their feet further apart to maintain balance. How should the nurse document this finding?
-
Lack of coordination
-
Positive Homan's sign
-
Ataxia
-
Positive Romberg's sign
Explanation
Explanation
Correct Answer Is:
D. Positive Romberg's sign
The Romberg test assesses proprioception and balance by having the patient stand with feet together and eyes closed. When visual input is removed, a patient with proprioceptive or vestibular dysfunction will sway or lose balance, indicating a positive Romberg's sign. This finding suggests dysfunction in the posterior column of the spinal cord or vestibular system.
Why the other options are incorrect:
A. Lack of coordination is a general term and not the specific clinical documentation appropriate for this standardized test finding.
B. Homan's sign involves pain in the calf upon dorsiflexion of the foot and is used to assess for deep vein thrombosis, not balance.
C. Ataxia refers to a general lack of voluntary muscle coordination and is not the specific term used to document the result of the Romberg test.
Correct Answer Is:
D. Positive Romberg's sign
The Romberg test assesses proprioception and balance by having the patient stand with feet together and eyes closed. When visual input is removed, a patient with proprioceptive or vestibular dysfunction will sway or lose balance, indicating a positive Romberg's sign. This finding suggests dysfunction in the posterior column of the spinal cord or vestibular system.

A. Lack of coordination is a general term and not the specific clinical documentation appropriate for this standardized test finding.
B. Homan's sign involves pain in the calf upon dorsiflexion of the foot and is used to assess for deep vein thrombosis, not balance.
C. Ataxia refers to a general lack of voluntary muscle coordination and is not the specific term used to document the result of the Romberg test.
8. The nurse is assessing tactile discrimination in the Posterior (Dorsal) Column Tract and traces a number in a patient's palm. With the patient's eyes closed, the patient correctly identifies the number. What is this test called?
-
Stereognosis
-
Two-point discrimination
-
Rapid alternating movements
-
Graphesthesia
Explanation
Explanation
Correct Answer Is:
D. Graphesthesia
Graphesthesia is the ability to identify numbers, letters, or shapes traced on the skin with eyes closed. It tests the integrity of the posterior dorsal column tract, which carries fine touch and proprioceptive information to the brain. Correctly identifying a traced number confirms intact sensory pathways.
Why the other options are incorrect:
A. Stereognosis involves identifying a familiar object placed in the hand by touch alone with eyes closed, not identifying traced numbers or letters.
B. Two-point discrimination tests the ability to distinguish between two points of simultaneous touch and how close together they can be before feeling like one point.
C. Rapid alternating movements test cerebellar function and coordination by asking the patient to rapidly pronate and supinate the hands, not sensory discrimination.
Correct Answer Is:
D. Graphesthesia

9. What number is used to indicate normal or average deep tendon reflexes on a 4-point scale?
-
1+
-
4+
-
3+
-
2+
Explanation
Explanation
Correct Answer Is:
D. 2+
On the standard deep tendon reflex grading scale, 2+ indicates a normal or average reflex response. The scale is as follows: 0 = absent, 1+ = diminished, 2+ = normal, 3+ = increased but not necessarily abnormal, 4+ = hyperactive with clonus, suggesting neurological pathology.
Why the other options are incorrect:
A. 1+ indicates a diminished or below-normal reflex response, suggesting possible nerve or muscle pathology.
B. 4+ indicates a hyperactive reflex with clonus, which is abnormal and associated with upper motor neuron lesions.
C. 3+ indicates an above-average but not necessarily pathological reflex response.
Correct Answer Is:
D. 2+

10. During an assessment of an 80-year-old patient, the nurse notices the following: inability to identify vibrations at the ankle and to identify position of big toe, slower and more deliberate gait, and slightly impaired tactile sensation. How should the nurse interpret what these findings indicate?
-
Cranial nerve dysfunction
-
Demyelination of nerves due to a lesion
-
Normal changes due to aging
-
Lesion in the cerebral cortex
Explanation
Explanation
Correct Answer: C. Normal changes due to aging
In older adults, age-related neurological changes include decreased vibratory sensation (especially in the lower extremities), reduced proprioception (position sense), slower and more cautious gait, and mild decline in tactile sensation. These changes result from normal degeneration of peripheral nerve fibers and are expected findings in an 80-year-old patient.
Why Other Options are Incorrect:
A. Cranial nerve dysfunction would present with deficits in head and neck functions such as facial movement, vision, hearing, or swallowing, not peripheral sensory changes in the lower extremities. B. Demyelination due to a lesion would typically present with more pronounced and asymmetric neurological deficits rather than the subtle, bilateral, age-consistent changes described. D. A cerebral cortex lesion would cause more significant neurological deficits such as weakness, aphasia, or cognitive changes, not the mild peripheral sensory changes described here.
