The nurse practitioner (NP) is working in an urgent care clinic which advertises treatment for "broken bones." Which is not a correct definition of each classification of fracture?
Transverse: Diagonal break across the bone
Greenstick: Bone cracks through one side only
Comminuted: Bone is crushed into many pieces
Segmental: The same bone is fractured in two places, so there is a "floating" segment of bone
The Correct Answer is A
Choice A reason: A transverse fracture is a horizontal break across the bone, not diagonal. A diagonal break is an oblique fracture.
Choice B reason: A greenstick fracture occurs when the bone bends and cracks on one side without breaking completely, consistent with the definition provided.
Choice C reason: Comminuted fractures involve the bone being crushed into multiple fragments, accurately described.
Choice D reason: Segmental fractures involve the same bone being broken in two or more distinct places, leaving a floating segment between breaks, consistent with the description.

Correct Answer is D
Explanation
Choice A reason: Bipolar II disorder involves at least one hypomanic episode and one major depressive episode, but this patient has a history of full manic episodes, not hypomania.
Choice B reason: While bipolar I disorder with a current or most recent depressive episode captures the depressive phase, it does not account for the chronic depressive symptoms predating manic episodes.
Choice C reason: Cyclothymic disorder involves chronic fluctuating mood states without meeting criteria for full manic or major depressive episodes. This does not match the patient’s manic history.
Choice D reason: Bipolar I disorder with coexisting persistent depressive disorder (dysthymia) accounts for the patient’s chronic depressive symptoms and history of full mania, making it the most accurate diagnosis.
Correct Answer is C
Explanation
Choice A reason: Claustrophobia may cause discomfort or anxiety during MRI, but it is not an absolute contraindication; sedation or open MRI can be used.
Choice B reason: Essential hypertension is not a contraindication; blood pressure is monitored but MRI can still be performed safely.
Choice C reason: Implanted defibrillators can malfunction or pose a serious risk in the strong magnetic field of MRI, making this an absolute contraindication unless the device is MRI-compatible.
Choice D reason: Intrauterine devices are generally safe for MRI; they may cause minor artifact but do not pose significant risk.
