Which radiographic diagnostic test is most helpful in confirming gallstones?
Computed tomography (CT).
Ultrasound.
Magnetic resonance angiography (MRA).
Abdominal x-ray.
The Correct Answer is B
Choice A reason: CT scans can detect gallstones but are less specific and involve radiation, making them secondary to ultrasound. Ultrasound is the preferred test for its accuracy and safety, making this less optimal and incorrect compared to the primary diagnostic tool for confirming gallstones.
Choice B reason: Ultrasound is the most helpful test for confirming gallstones, offering high sensitivity and specificity without radiation. It visualizes stones clearly in the gallbladder, aligning with diagnostic guidelines, making it the correct choice for the nurse to identify as the primary radiographic test for gallstones.
Choice C reason: MRA focuses on vascular structures, not gallstones, and is irrelevant for gallbladder assessment. Ultrasound is the standard for gallstone confirmation, making this inappropriate and incorrect compared to the non-invasive, effective imaging method used in diagnosing gallbladder conditions.
Choice D reason: Abdominal x-rays detect only calcified gallstones, missing non-calcified ones, which are common. Ultrasound is more comprehensive, making this less reliable and incorrect compared to the preferred diagnostic test for accurately confirming gallstones in a clinical setting.

Correct Answer is ["A","B","C"]
Explanation
Choice A reason: Obesity, particularly central, is common in Cushing syndrome due to cortisol-induced fat redistribution. This aligns with endocrine assessment findings, making it a correct manifestation the nurse would expect when evaluating a patient with Cushing syndrome for physical signs.
Choice B reason: Bruising occurs in Cushing syndrome due to cortisol weakening blood vessels and skin. This is a typical integumentary finding, aligning with clinical assessments, making it a correct manifestation the nurse would note in a patient with Cushing syndrome during evaluation.
Choice C reason: Edema results from cortisol’s mineralocorticoid effects, causing fluid retention in Cushing syndrome. This aligns with cardiovascular and fluid balance assessments, making it a correct manifestation the nurse would expect when assessing a patient with this endocrine disorder.
Choice D reason: Abdominal pain is not a primary manifestation of Cushing syndrome, though striae or muscle weakness may occur. Obesity and bruising are more specific, making this incorrect, as it is not a typical finding in the nurse’s assessment of Cushing syndrome.
Choice E reason: Bronze skin is associated with Addison’s disease, not Cushing syndrome, which causes moon facies or buffalo hump. Obesity and edema are correct, making this incorrect, as it misattributes a finding to Cushing syndrome in the nurse’s assessment.
Correct Answer is A
Explanation
Choice A reason: A bowel program prevents fecal impaction, a common trigger of autonomic dysreflexia in T4 paraplegia patients. This aligns with spinal cord injury care protocols, making it the correct nursing action to include in the home health plan to prevent this hypertensive emergency.
Choice B reason: A high-protein diet supports nutrition but doesn’t directly prevent autonomic dysreflexia, triggered by stimuli like impaction. A bowel program is more relevant, making this incorrect, as it doesn’t address the primary cause of dysreflexia in the patient’s care plan.
Choice C reason: Quad coughing aids respiratory function but is unrelated to preventing autonomic dysreflexia, caused by visceral stimuli. A bowel program targets this risk, making this incorrect, as it doesn’t address the triggers of dysreflexia in the T4 paraplegia patient’s plan.
Choice D reason: Discussing sexuality and fertility supports quality of life but doesn’t prevent autonomic dysreflexia, linked to physical triggers. A bowel program is preventive, making this incorrect, as it’s unrelated to the physiological causes of dysreflexia in the home health care plan.
