What typical sign/symptom indicates the early stage of septic shock?
Tachypnoea and tachycardia
Pallor and cool skin
Blood pressure 84/50 mm Hg
Respiratory acidosis
The Correct Answer is A
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 D
Explanation
When the low-pressure alarm sounds, it indicates that the pressure being detected by the arterial line is below the set threshold. This could be due to a variety of reasons, such as a loose connection, air bubbles, or a shift in the zero-reference point.
Rezeroing the monitoring equipment involves recalibrating or resetting the baseline reference point for the arterial pressure waveform. This ensures accurate measurement and monitoring of the patient's arterial pressure.
A. Checking the right hand for a rash in (option A) is incorrect because While assessing the patient for any skin changes or rashes is important, it is not the first action to take in response to a low-pressure alarm.
B. Assessing the waveform for under-dampening in (option B) is incorrect because Assessing the waveform characteristics is important in arterial line monitoring, but it may not be the initial action when the low-pressure alarm sounds. Rezeroing the equipment should be performed before assessing waveform characteristics.
C. Assessing for cardiac dysrhythmias in (option C) is incorrect because Assessing for dysrhythmias is an important aspect of patient care, but it may not be directly related to the low-pressure alarm from the arterial line. Rezeroing the monitoring equipment takes precedence.
Therefore, when the low-pressure alarm sounds for a patient with an arterial line, the nurse should first re-zero the monitoring equipment to ensure accurate measurement of arterial pressure.
Correct Answer is B
Explanation
Disseminated Intravascular Coagulation (DIC) is a condition characterized by widespread activation of the coagulation system, leading to both excessive clot formation and consumption of clotting factors and platelets. This process can result in both bleeding and thrombosis.
The manifestations mentioned in option B are commonly seen in DIC:
Decreased platelet counts: DIC leads to platelet consumption and destruction, resulting in low platelet counts (thrombocytopenia).
Increased D-dimer: D-dimer is a fibrin degradation product, and its levels are increased DIC due to the breakdown of fibrin clots.
Increased prothrombin time (PT): DIC can lead to the depletion of clotting factors, resulting in prolonged prothrombin time, indicating impaired coagulation.
The other options mentioned do not represent the typical clinical manifestations of DIC:
A. Decreased hematocrit, increased platelet counts, and increased D-dimer in (option A) are incorrect because While platelet counts and D-dimer are increased in DIC, decreased hematocrit is not a characteristic finding.
C. Decreased Antithrombin III, increased platelet counts, and increased fibrinogen in (option C) is incorrect because: Decreased Antithrombin III can be seen in DIC, but increased platelet counts and fibrinogen levels are not specific to DIC.
D. Decreased D-dimer, increased platelet counts, and increased hemoglobin in (option D) is incorrect because Decreased D-dimer and increased hemoglobin are not typical findings in DIC, while increased platelet counts can be seen in some cases.
