Question 1 of 5
Jake is a 32-year-old patient who is recovering from major abdominal surgery and organ resection following a catastrophic motor vehicle accident. Due to the nature of his injuries, a large portion of his jejunum had to be resected. In planning for his recovery and nutritional needs, the AGACNP considers that
Correct Answer: B
Rationale: The jejunum is the primary site for absorption of nutrients, including vitamin B12. Resection of a large portion of the jejunum can lead to malabsorption of vitamin B12, as this nutrient is primarily absorbed in the distal ileum but also partially absorbed in the jejunum. Thus, Jake is at significant risk for B12 absorption problems following his surgery, and close monitoring and potential supplementation may be needed to address this issue.
Question 2 of 5
The AGACNP recognizes that which of the following diagnostic studies is essential in all cases of acute abdomen?
Correct Answer: C
Rationale: Ultrasonography is considered essential in all cases of acute abdomen because it is a valuable tool in evaluating various abdominal organs non-invasively. It can quickly identify common causes of acute abdomen such as cholecystitis, pancreatitis, appendicitis, and other intra-abdominal pathologies. Ultrasonography also has the advantage of being radiation-free and can be performed rapidly at the bedside, making it a preferred initial diagnostic modality in the evaluation of acute abdominal pain. Abdominal radiograph, contrast radiography, and chest radiography may have limited utility in the evaluation of acute abdomen compared to ultrasonography.
Question 3 of 5
The AGACNP knows that when managing a patient with acute cardiogenic shock after myocardial infarction, all of the following pharmacologic agents may be used except
Correct Answer: A
Rationale: Anticholinergics are not typically used in the management of acute cardiogenic shock after myocardial infarction. Anticholinergic medications may worsen tachycardia and exacerbate myocardial ischemia by increasing heart rate and myocardial oxygen demand. Therefore, the AGACNP should avoid using anticholinergics in this patient population.
