After the nurse obtains a blood sample from a client's right radial arterial client reports a sudden onset of pain at the arterial line insertion site. The nurse recognizes which physiological effect may be inducing the sudden pain?
Elevation in blood pressure.
Vasospasm at insertion site.
Clot in the arterial catheter.
Air lock in the transducer.
The Correct Answer is B
A) Elevation in blood pressure:
While elevation in blood pressure could potentially cause discomfort at the arterial line insertion site, it is not the most likely physiological effect to induce sudden pain in this scenario. Blood pressure elevation would typically cause generalized symptoms rather than localized pain at the insertion site.
B) Vasospasm at insertion site:
Correct. Vasospasm refers to the sudden constriction of blood vessels, leading to reduced blood flow. It can occur in response to arterial puncture or manipulation during arterial line insertion, resulting in sudden pain at the insertion site.
C) Clot in the arterial catheter:
A clot in the arterial catheter could potentially cause obstruction and affect blood flow, but it is less likely to induce sudden pain at the insertion site unless there is associated ischemia or tissue damage.
D) Air lock in the transducer:
An air lock in the transducer could disrupt pressure monitoring but is not typically associated with sudden pain at the insertion site. It may lead to inaccurate pressure readings rather than localized pain.

Correct Answer is C
Explanation
DKA is a serious complication of diabetes mellitus characterized by hyperglycemia, ketosis, and metabolic acidosis. The laboratory results consistent with DKA include:
Elevated blood glucose level: A blood glucose level of 525 mg/dL (28 mmol/L) is significantly elevated and consistent with DKA.
Low arterial blood pH: A decreased arterial blood pH indicates acidosis, which is characteristic of DKA. Normal arterial blood pH ranges from 7.35 to 7.45.
Low bicarbonate (HCO3-) level: A low bicarbonate level indicates metabolic acidosis, which is also characteristic of DKA. Normal bicarbonate levels range from 21 to 28 mEq/L (21 to 28 mmol/L).
Among the options provided:
A) Arterial blood pH 7.5 and bicarbonate level 32 mEq/L (32 mmol/L):
This pH and bicarbonate level are indicative of alkalosis, which is not consistent with DKA.
B) Arterial blood pH 7.42 and bicarbonate level 18 mEq/L (18 mmol/L):
This pH is within the normal range, and the bicarbonate level is slightly decreased but not indicative of metabolic acidosis consistent with DKA.
C) Arterial blood pH 7.25 and bicarbonate level 10 mEq/L (10 mmol/L):
Correct. This pH is decreased, indicating acidosis, and the bicarbonate level is significantly below the normal range, consistent with metabolic acidosis characteristic of DKA.
D) Arterial blood pH 7.38 and bicarbonate level 29 mEq/L (29 mmol/L):
While the pH is within the normal range, the bicarbonate level is elevated, which is not consistent with metabolic acidosis seen in DKA.
Correct Answer is A
Explanation
A) Blockage of retinal capillaries causing ischemic damage of the central macular area:
Correct. Blurry central vision that worsens over time can be indicative of macular ischemia, often caused by blockage of retinal capillaries leading to ischemic damage of the central macular area. This condition can occur in diseases such as diabetic retinopathy or retinal vein occlusion.
B) Opaque spoke-like lines developing in the periphery of the lens to the center:
This description is more characteristic of cataracts, which cause visual disturbances such as glare or halos around lights rather than blurry central vision.
C) Tears in the retina that detach from the lining of the posterior eyeball:
Retinal tears and subsequent detachment can cause visual disturbances, but they typically present as sudden onset of floaters, flashes of light, and a curtain-like shadow over the visual field rather than blurry central vision.
D) An increase in intraocular pressure with loss of peripheral vision:
This description is indicative of glaucoma, which can lead to loss of peripheral vision (visual field defects) rather than blurry central vision. Glaucoma-related visual field loss usually begins peripherally and progresses inward, affecting central vision in later stages.
