The nurse practitioner is performing a neurological assessment on an infant and places a finger in the infant's hand. The infant flexes all fingers to grasp the practitioner's finger. This maneuver assesses the:
plantar grasp reflex.
palmar grasp reflex.
Landau reflex.
Galant reflex.
The Correct Answer is B
Rationale:
A. The plantar grasp reflex is elicited by stroking the sole of the infant’s foot, causing the toes to curl, not the fingers.
B. The palmar grasp reflex is tested by placing a finger in the infant’s palm, resulting in flexion of all fingers to grasp it. This reflex is present at birth and typically disappears by 5–6 months of age.
C. The Landau reflex involves the infant lifting the head and arching the back when held prone, unrelated to grasping.
D. The Galant reflex is elicited by stroking the lateral trunk, causing the infant to laterally flex toward the stimulus; it does not involve hand grasping.

Correct Answer is B
Explanation
Rationale:
A. A urethral opening on the dorsal aspect of the glans penis is consistent with epispadias, not hypospadias.
B. Hypospadias is a congenital condition in which the urethral opening is located on the ventral (underside) aspect of the penis, rather than at the tip of the glans. Early detection is important for surgical planning and preventing complications with urination or future sexual function.
C. Inability to retract the foreskin over the glans penis is phimosis and is not diagnostic of hypospadias.
D. Inability to palpate a testicle suggests cryptorchidism, which is unrelated to the urethral meatus position.
Correct Answer is B
Explanation
Rationale:
A. Pneumonia typically causes crackles, wheezing, fever, and cough, but not acute stridor.
B. Epiglottitis is a life-threatening condition in infants and young children that causes acute stridor, drooling, fever, and respiratory distress. Stridor is a hallmark sign of upper airway obstruction in this scenario.
C. Bronchiolitis usually causes wheezing and respiratory distress, but stridor is less common unless severe upper airway involvement occurs.
D. Apnea refers to pauses in breathing and may be associated with cyanosis or bradycardia but does not cause stridor.
