He has had 1 L of NSS infused by emergency medical services. His vital signs reveal a pulse of 128 bpm and a blood pressure of 8860 mm Hg. With respect to his hypotension, the AGACNP recognizes that

  • A. Vasopressors are contraindicated in traumatic head injury
  • B. Hypotension doubles the risk of mortality from traumatic head injury
  • C. His blood pressure is likely a physiologic response to traumatic head injury
  • D. Stabilizing the head injury is more important that identifying the cause of hypotension
Correct Answer: D

Rationale: In this scenario, the patient's low blood pressure is likely a physiologic response to traumatic head injury. Hypotension can occur as a compensatory mechanism in traumatic brain injury to maintain cerebral perfusion. The body may reduce blood pressure to decrease the risk of further brain injury or bleeding. It is important for the AGACNP to recognize that in traumatic brain injury, hypotension may not necessarily require immediate intervention with vasopressors, as it may be a protective response. Monitoring and managing the patient's condition closely, including neurologic status and trends in blood pressure, is crucial in this situation.

R. S. is a 66-year-old female with Cushings syndrome due to an ACTH-producing pituitary tumor. The tumor is readily isolated by imaging, and the patient had an uneventful surgery. When seeing her in follow-up, the AGACNP anticipates

  • A. Rapid reversal of symptoms, with good pituitary function
  • B. Transient rebound release of remaining pituitary hormones
  • C. Markedly improved dexamethasone suppression test
  • D. Hyponatremia and compensatory SIADH
Correct Answer: A

Rationale: In patients with Cushing's syndrome due to an ACTH-producing pituitary tumor, removal of the tumor can result in a transient rebound release of remaining pituitary hormones. This occurs because the suppressed pituitary gland begins to recover and overproduce hormones in response to the sudden decrease in negative feedback from the removed tumor. As a result, patients may experience transient hormonal fluctuations before the pituitary gland establishes a new equilibrium. Therefore, when seeing the patient in follow-up after surgery, the AGACNP should anticipate a transient rebound release of remaining pituitary hormones rather than immediate and rapid reversal of symptoms or markedly improved test results. Additionally, hyponatremia and compensatory SIADH are less likely in this scenario unless there are other underlying factors contributing to it.

Which one of the following is a prerequisite for forceps delivery?

  • A. Intact membranes
  • B. Ruptured membranes
  • C. Cephalic presentation

Vitamin K prevents hemorrhagic disease of the neonate by

  • A. Activating the white blood cells
  • B. Activating the dormant clotting factors
  • C. Adopting a fibrinogen sparing mechanism
  • D. Altering the red blood cells count

Uterine apoplexy is associated with

  • A. Postpartum haemorrhage
  • B. Hyperemesis gravidarum
