The enlargement of both nasal openings during inspiration is known as:
nasal grunting
nasal stridor.
nasal flaring.
nasal obstruction.
The Correct Answer is C
Rationale:
A. Nasal grunting is a sound produced during exhalation due to partial airway obstruction, not visible enlargement of the nostrils.
B. Nasal stridor refers to a high-pitched sound during breathing caused by upper airway obstruction, not the physical widening of nasal openings.
C. Nasal flaring is the visible enlargement of both nostrils during inspiration, often seen in infants and young children as a sign of respiratory distress. It helps reduce airway resistance and increase airflow.
D. Nasal obstruction is a blockage of nasal passages and does not describe the outward flaring of nostrils.

C. Anorexia nervosa can cause delayed sexual development in adolescent females due to malnutrition and low body fat, which disrupts hypothalamic-pituitary-ovarian axis function, leading to delayed puberty or amenorrhea.

Correct Answer is B
Explanation
Rationale:
A. A bulb syringe delivers low pressure and is less effective for thoroughly cleansing an open wound, especially if debris is present.
B. A 20-mL catheter tip syringe allows controlled irrigation with sufficient pressure (approximately 8 psi) to effectively remove debris and contaminants without damaging healthy tissue. This is considered the standard method for wound irrigation.
C. Using an IV bag without pressure may not provide adequate force to flush out debris and contaminants.
D. Gauze compresses can clean the wound surface but do not provide the irrigation pressure necessary for thorough cleansing.
