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
- A. Opioids
- B. Diuretics
- C. Beta-adrenergic antagonists
- D. Anticholinergics
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.

Melanie is a 31-year-old patient who is being evaluated following a routine urinalysis that revealed microscopic hematuria. She was between menses and has no other identifiable explanation for hematuria. She has no significant medical history and otherwise is without complaint. The AGACNP knows that workup for Melanie should include
- A. A urology consultation
- B. CT urogram
- C. Upper urinary imaging
- D. Cystoscopy
Correct Answer: D
Rationale: Upper urinary imaging is the appropriate next step in the workup for Melanie based on the presentation of microscopic hematuria with no other identifiable explanation. Upper urinary imaging, such as an ultrasound or CT scan, can help evaluate the upper urinary tract, including the kidneys and ureters, to investigate potential causes of hematuria. This step is commonly recommended before proceeding to invasive procedures like cystoscopy or consultation with a urologist. It allows for a non-invasive assessment of the upper urinary system to identify any potential abnormalities that may be causing the hematuria in the patient.
