In laryngeal stridor, the noise is more marked during

Correct Answer: A

Rationale: The correct answer is A: Inspiration. Laryngeal stridor is caused by narrowed or obstructed airway, resulting in noisy breathing. During inspiration, the air is drawn through the narrowed larynx, causing the stridor sound. During expiration, the air is leaving the body, so the noise may not be as prominent. Choices C and D, feeding and play, are unrelated to the respiratory process and do not affect the presence of laryngeal stridor.

Correct Answer: A

Rationale: The correct answer is A: Clonic stage. In eclampsia, the clonic stage is characterized by violent contraction and relaxation of the whole body due to generalized seizures. During this stage, rhythmic jerking movements occur. The other choices are incorrect because: B: Coma stage - In this stage, the individual is unconscious and not experiencing violent body movements. C: Premonitory stage - This stage includes warning signs like headache and visual disturbances, but not the violent body movements seen in eclampsia. D: Tonic stage - This stage involves sustained muscle contractions without relaxation, unlike the alternating contraction and relaxation seen in the clonic stage of eclampsia.

Correct Answer: B

Rationale: The correct answer is B because pressure applied on the cervix by the presenting part in obstructed labor leads to edema of the vulva. This pressure causes obstruction of blood and lymphatic flow in the area, resulting in swelling and edema. Prolonged effort by the mother (choice A) would not directly cause vulvar edema. An ill-fitting presenting part (choice C) may contribute to obstruction but does not explain the mechanism of edema. Large presenting diameters (choice D) stretching the vulva would not directly cause edema without pressure on the cervix.

Correct Answer: B

Rationale: The correct answer is B: Trial of scar. This term specifically refers to the process of attempting a vaginal birth after a previous caesarean section. It involves monitoring the previous cesarean scar for any signs of complications during labor. A: Spontaneous vaginal delivery refers to giving birth vaginally without any previous cesarean section. C: Spontaneous vertex delivery simply describes the position of the baby's head during birth. D: Trial of birth is not a commonly used term in obstetrics and does not specifically relate to VBAC.

Correct Answer: B

Rationale: The correct answer is B: Hyperextension casting. The AGACNP knows that this treatment is appropriate for a condition that requires immobilization and support while allowing controlled movement. Hyperextension casting provides stability and support while promoting healing. Observation (A) would not provide adequate treatment for a condition requiring immobilization. Jewett brace (C) is typically used for spinal fractures, not for conditions that require hyperextension casting. Surgical intervention (D) would be considered if conservative measures like casting have failed.
