Question 1 of 5
The AGACNP is going over preoperative information and instructions with a patient who is having a major transverse abdominal procedure tomorrow morning. The patient is very nervous and is asking a lot of questions. The AGACNP prescribes a sleeping agent because he knows that anxiety and sleeplessness may
Correct Answer: C
Rationale: Anxiety and sleeplessness can contribute to the risk of delirium and prolonged length of stay for the patient undergoing a major transverse abdominal procedure. Delirium is a common complication seen in patients who are anxious and sleep-deprived, especially postoperatively. It is important to address these issues preoperatively to help prevent delirium and ensure a smoother recovery process for the patient. By prescribing a sleeping agent, the AGACNP aims to reduce anxiety and promote a good night's sleep, which can ultimately decrease the risk of delirium and lead to better outcomes for the patient.
Question 2 of 5
P. T. is a 58-year-old female who is admitted with chest pain and shortness of breath and is found to have a large pulmonary embolus. Her systolic blood pressure is falling, and a diagnosis of obstructive shock is made. Cardiac pressure would likely demonstrate
Correct Answer: B
Rationale: Obstructive shock, such as in this case of a large pulmonary embolus causing obstructive shock, results in a sudden increase in right ventricular afterload due to obstruction of blood flow. This leads to right heart failure and decreased left ventricular preload, ultimately resulting in decreased cardiac output. The elevated right-sided pressures will be reflected by elevated right atrial and ventricular pressures, while the left ventricular pressures will be decreased due to decreased preload. This commonly leads to a situation known as acute cor pulmonale, where the right heart becomes dilated and dysfunctional in response to the increased afterload.
Question 3 of 5
What are the potential complications associated with a post-term pregnancy?
Correct Answer: D
Rationale: Post-term pregnancies carry risks like macrosomia, placental insufficiency, and meconium aspiration.
Question 4 of 5
The AGACNP is receiving report from the recovery room on a patient who just had surgical resection for pheochromocytoma. He knows that which class of drugs should be available immediately to manage hypertensive crisis, a possible consequence of physical manipulation of the adrenal medulla?
Correct Answer: C
Rationale: Surgical manipulation of the adrenal medulla during resection of a pheochromocytoma can result in the release of catecholamines leading to a hypertensive crisis. Alpha-adrenergic antagonists, such as phenoxybenzamine or prazosin, are the drugs of choice for managing hypertensive crisis in this situation. These medications block the alpha-adrenergic receptors, leading to vasodilation and lowering of blood pressure. Beta-adrenergic antagonists are contraindicated in this scenario due to the risk of unopposed alpha-adrenergic stimulation that could worsen the hypertension. Intravenous vasodilators and arteriolar dilators may be used as adjunctive therapy but alpha-adrenergic antagonists are the primary agents for managing hypertensive crisis in this context.
Question 5 of 5
When a patient is hospitalized with a possible stroke, the AGACNP recognizes that the stroke most likely resulted from a subarachnoid hemorrhage when the patients family reports that the patient
Correct Answer: A
Rationale: The key clinical manifestation indicating a possible subarachnoid hemorrhage in this scenario is that the patient had been complaining of a headache before losing consciousness. Subarachnoid hemorrhage is a type of stroke that results from bleeding into the space between the arachnoid membrane and the pia mater surrounding the brain. Severe headache, often described as the worst headache of one's life, is a classic symptom of subarachnoid hemorrhage. The sudden onset of a severe headache before loss of consciousness raises the suspicion for this type of stroke. Other symptoms such as mental confusion and weakness may also be present, but the headache is a crucial indicator in this case.
