An arterial catheter is inserted in the right radial artery to monitor a patient's blood pressure. Which information obtained by the nurse indicates that a complication of arterial pressure monitoring may be occurring?
Allen's test is positive.
The mean arterial pressure (MAP) is 90 mm Hg.
The dicrotic notch is visible in the waveform.
The right hand is numb.
The Correct Answer is D
Arterial pressure monitoring involves the insertion of an arterial catheter, typically in the radial artery, to directly measure blood pressure. Complications can arise from this invasive procedure, and one potential complication is inadequate blood flow to the hand, leading to numbness or ischemia.
A. The Allen's test is positive in (option A) is incorrect because The Allen's test is performed before arterial catheter insertion to assess the collateral circulation of the hand. A positive Allen test indicates adequate collateral circulation, which is desirable before performing the procedure. However, it does not directly indicate a complication during or after arterial pressure monitoring.
B. The mean arterial pressure (MAP) is 90 mm Hg in (option B) is incorrect because The mean arterial pressure (MAP) represents the average pressure in the arterial system during one cardiac cycle. While changes in MAP can be significant for patient management, it does not specifically indicate a complication of arterial pressure monitoring.
C. The dicrotic notch visible in the waveform in (option C) is incorrect because The dicrotic notch represents the closure of the aortic valve and is a normal finding in arterial waveforms. Its presence does not indicate a complication.

Correct Answer is B
Explanation
A. Oxygen saturation of 92% in (option A) is incorrect because While an oxygen saturation of 92% is suboptimal and may require intervention, it may not have the same immediate implications as low blood pressure. The healthcare provider should be informed, but addressing the blood pressure takes priority.
B. Skin cool and clammy in (option B) is correct because Cool and clammy skin is often associated with inadequate peripheral perfusion, which is a characteristic of septic shock.
C. Septic shock is characterized by systemic inflammation, vasodilation, and hypotension. Inadequate blood pressure is a significant concern in septic shock as it indicates poor tissue perfusion and compromised organ function. However, the mean arterial pressure is till acceptable.
D. Heart rate of 118 beats/minute in (option D) is incorrect because: Tachycardia is a common finding in septic shock and reflects the body's compensatory response to maintain cardiac output. While it is a significant finding, low blood pressure takes precedence in terms of urgency.
Correct Answer is A
Explanation
The stages of shock are commonly described as the initial, compensatory, progressive, and refractory stages. Here is an explanation of each stage and why the patient's assessment findings correspond to the progressive stage:
B. The compensatory stage in (option B) is incorrect because, In the compensatory stage, the body continues to activate compensatory mechanisms to maintain perfusion. This includes increased heart rate, peripheral vasoconstriction, and shunting of blood to vital organs. The patient's assessment findings of decreasing cardiac output, decreased peripheral perfusion, and increased capillary permeability suggest that the body's compensatory mechanisms are no longer sufficient to maintain perfusion adequately. Therefore, the patient has progressed beyond the compensatory stage.
C. The initial stage in (option C) is incorrect because, In the initial stage, there is an initial insult or injury that triggers the shock state. The body's compensatory mechanisms are activated, such as increased heart rate and vasoconstriction, to maintain blood pressure and perfusion. However, the patient's assessment findings indicate that they have progressed beyond the initial stage.
D. The refractory stage in (option D) is incorrect because The refractory stage represents a severe and irreversible state of shock where vital organs fail, and despite interventions, the patient's condition does not improve. The patient's assessment findings do not suggest the refractory stage, as there is still potential for intervention and management.
