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 A
Explanation
In the early stage of septic shock, the body initiates compensatory mechanisms to combat the infection and restore adequate tissue perfusion. Tachypnoea (rapid breathing) and tachycardia (elevated heart rate) are common early signs of septic shock.
Tachypnoea occurs as a response to increased metabolic demand and to compensate for impaired oxygenation and tissue perfusion. Tachycardia is the body's attempt to maintain cardiac output and compensate for decreased blood pressure.
B. Pallor and cool skin in (option B) is incorrect because Pallor and cool skin can occur in later stages of septic shock when perfusion to the peripheral tissues is compromised. However, they are not specific to the early stage.
C. Blood pressure 84/50 mm Hg in (option C) is incorrect because A blood pressure reading of 84/50 mm Hg indicates hypotension, which is typically seen in later stages of septic shock. In the early stage, blood pressure may still be within normal or slightly decreased range.
D. Respiratory acidosis in (optionD) is incorrect because: Respiratory acidosis refers to an imbalance in acid-base status and is not specific to the early stage of septic shock. Acid-base disturbances may occur at any stage of shock but are not indicative of the early stage.
Correct Answer is B
Explanation
The patient's symptoms of fever and elevated white blood cell count suggest a potential infection and sepsis. Broad-spectrum antibiotics should be initiated promptly to cover a wide range of possible pathogens until further diagnostic tests and identification of the specific causative agent are obtained. Early administration of appropriate antibiotics is crucial in sepsis management to target the suspected infection and improve patient outcomes.
A. Cooling baths in (option A) is incorrect because: Cooling baths are typically used in the management of hyperthermia or specific conditions like heatstroke. While the patient has an elevated temperature, it is likely due to the systemic inflammatory response rather than solely hyperthermia.
C. Blood transfusion in (option C) is incorrect because Blood transfusion may be required in certain cases of sepsis if there is evidence of significant anemia or active bleeding. However, based on the information provided, there is no immediate indication of a blood transfusion.
D. NPO status in (option D) is incorrect because NPO status (nothing by mouth) is a general precautionary measure used in various situations, such as prior to surgery or to manage gastrointestinal complications. It is not a specific intervention in the sepsis resuscitation bundle.
Therefore, the nurse should initiate the intervention of administering broad-spectrum antibiotics in this scenario.
