enna is a 41-year-old female who presents to the emergency room complaining of sudden hearing loss. She is generally very healthyshe denies any significant medical history, and her only daily medication is a combined oral contraceptive. She does admit that she is just getting over a head cold, but other than that she offers no relevant history. A comprehensive history and physical examination results in a diagnosis of sudden sensorineural hearing loss (SSHL) of unknown origin. The AGACNP knows that the next step in the patients management should include

Correct Answer: D

Rationale: The correct answer is D: Hyperbaric oxygen. SSHL is a medical emergency that requires prompt intervention. Hyperbaric oxygen therapy increases oxygen delivery to the inner ear, potentially reversing the hearing loss. Acyclovir (A) is used for viral infections, not SSHL. Furosemide (B) is a diuretic used for treating fluid retention, not SSHL. Warfarin (C) is an anticoagulant and is not indicated for SSHL. In summary, hyperbaric oxygen is the appropriate choice for managing SSHL due to its potential to improve oxygen delivery to the inner ear.

Correct Answer: C

Rationale: The correct answer is C: Gastric retention. Mrs. Coates' symptoms of persistent and progressive discomfort are not likely due to gastric retention because she underwent a duodenal resection for a bleeding ulcer, which would bypass the stomach. Therefore, gastric retention is not a possible cause. A: Colic due to return of peristalsis is a possible cause as peristalsis returning after surgery can cause discomfort. B: Leakage from the duodenal stump is a possible cause as it can lead to abdominal discomfort postoperatively. D: Hemorrhage is a possible cause given her history of bleeding ulcer and surgery.

Correct Answer: B

Rationale: The correct answer is B: Conduction. Conduction is the transfer of heat through direct contact. By keeping the neonatal unit warm and wrapping neonates in warm blankets, heat loss through direct contact with surfaces is minimized. Convection involves heat transfer through air or fluid movement, not relevant in this scenario. Evaporation is the process of heat loss through moisture evaporation from the skin, not applicable here. Radiation is heat transfer through electromagnetic waves, which can be prevented by warm wrapping but not the primary focus in this context.

Correct Answer: B

Rationale: The correct answer is B. It is important to manage medications appropriately preoperatively to minimize complications. Metoprolol, a beta blocker, should be continued up until the day of surgery to prevent rebound hypertension or tachycardia. Metformin should be held on the day of surgery to avoid potential lactic acidosis due to its effects on kidney function. Warfarin should be discontinued 5-7 days before surgery to reduce the risk of bleeding. Vitamin E can increase bleeding risk and should be discontinued. Choice A is incorrect as not all medications should be taken until the morning of surgery. Choice C is incorrect as warfarin should be held earlier than 5 days before surgery. Choice D is incorrect as metformin should be held on the day of surgery, regardless of blood sugar levels, to prevent lactic acidosis.

Correct Answer: A

Rationale: The correct answer is A because signs of obstructed labor include a dry vagina due to prolonged pressure, oedema of the cervix due to prolonged contractions, and caput succedaneum which is swelling of the baby's scalp from prolonged pressure. Choice B is incorrect because plenty of amniotic fluid is not a sign of obstructed labor. A hot/dry vagina is not a typical sign of obstructed labor. Meconium-stained liquor can be a sign of fetal distress, but not specifically obstructed labor. Choice C is incorrect because meconium-stained liquor is a sign of fetal distress, not necessarily obstructed labor. A hot/dry vagina is not a typical sign of obstructed labor. Diluted urine is not a typical sign of obstructed labor. Choice D is incorrect because while caput succedaneum is a sign of obstructed labor, oedema of the cervix is more indicative of obstructed labor than plenty of amni

Correct Answer: B

Rationale: The correct answer is B because reduced facial movement is a key clinical feature of facial palsy. This can lead to difficulty in making facial expressions, closing the eye on the affected side, and drooping of the mouth. Irritability may also occur due to discomfort or difficulty in communication. Choice A is incorrect because inability to feed and excessive cry are not typical features of facial palsy. Choice C is incorrect as excessively dry eyeball and feeding difficulties are not commonly associated with facial palsy. Choice D is incorrect as eyes being permanently open and no facial movement are not characteristic of facial palsy.

Correct Answer: A

Rationale: The correct answer is A: Uterine rupture. This is the most significant risk associated with VBAC, where the scar from the previous cesarean section may tear during labor. This can lead to severe complications for both the mother and baby. Postpartum hemorrhage (B) and placenta previa (C) are potential risks in any pregnancy but are not specifically increased in VBAC. Therefore, the correct answer is A, as it directly relates to the unique risk of VBAC.

Correct Answer: A

Rationale: The correct answer is A because uterine rupture can lead to severe complications such as hemorrhage from blood vessels tearing, uterine atony causing failure of the uterus to contract, infection due to exposure of internal tissues, and peritonitis from inflammation of the abdominal lining. Choices B and C are incorrect as they list complications that are not directly associated with uterine rupture. Preterm labor, cord prolapse, uterine prolapse, fetal distress, placental abruption are potential consequences of other obstetric complications but not specifically uterine rupture. Therefore, choice A is the most appropriate answer given the context of uterine rupture.

Correct Answer: D

Rationale: The correct answer is D: Fetal macrosomia. Fetal macrosomia, which refers to a baby being significantly larger than average, is an inorganic risk factor for birth injuries because it can lead to difficult delivery and increase the risk of birth trauma such as shoulder dystocia. Maternal short stature (A) is a biological risk factor, not inorganic. Prenatal oligohydramnios (B) refers to low levels of amniotic fluid and is a maternal condition, not an inorganic factor. External cephalic version (C) is a procedure to turn a breech baby and is not a risk factor for birth injuries.
