Which symptom found when examining the head would be a cause for concern?
Even distribution of hair.
Bruits in the temporal arteries.
Symmetrical features at rest.
Symmetrical features with movement.
The Correct Answer is B
A. Even distribution of hair: Hair that is evenly distributed across the scalp is considered a normal finding. It does not suggest any underlying pathology and therefore is not a cause for concern during head assessment.
B. Bruits in the temporal arteries: The presence of bruits indicates turbulent blood flow, which may be associated with vascular narrowing or inflammation such as temporal arteritis. This finding requires further evaluation as it may signal a serious vascular condition.
C. Symmetrical features at rest: Symmetry of facial features while the patient is at rest is a normal and expected finding. It demonstrates intact cranial nerve function and normal muscle tone.
D. Symmetrical features with movement: Symmetry during facial movements, such as smiling or raising eyebrows, is also considered normal. This finding suggests intact cranial nerve VII function.

Correct Answer is B
Explanation
A. Reflexes cannot be elicited: Even in unconscious patients, deep tendon reflexes (DTRs) may still be present unless there is specific spinal cord or peripheral nerve damage. Complete absence of reflexes is not expected solely from a head injury.
B. Some reflexes will be present, depending on the area of injury: While localized brain injury can affect voluntary motor control, DTRs are spinal reflexes and are generally preserved regardless of the site of brain trauma.
C. Reflexes will be normal: Deep tendon reflexes are intact in unconscious patients without spinal cord injury. The reflex arc operates independently of the patient’s level of consciousness, so normal DTRs are an expected finding.
D. All reflexes will be diminished but present: Reflex responses may vary; some may be normal, some diminished, and some exaggerated depending on the affected pathways. It is unlikely that all reflexes are uniformly diminished in head trauma without spinal involvement.
Correct Answer is D
Explanation
A. Fine hair is present: Hair is not normally found on the glans penis. Hair growth is typically limited to the pubic area and the base of the penis, so its presence on the glans would be abnormal.
B. The dorsal vein may be visible: The dorsal vein is located along the shaft of the penis, not on the glans. Its visibility is a normal finding on the shaft but not specifically on the glans itself.
C. The skin is wrinkled and without lesions: The skin of the glans penis is typically smooth and soft, not wrinkled. Wrinkled skin is characteristic of the scrotum, not the glans. The glans should be without lesions, but the skin texture is wrong.
D. Smegma may be present under the foreskin of an uncircumcised male: Smegma, a whitish secretion composed of dead skin cells and oils, is a normal finding beneath the foreskin in uncircumcised males and can be gently cleaned during hygiene.
