A 78-kg patient in septic shock has a pulse rate of 120 beats/min with low central venous pressure and pulmonary artery wedge pressure. After initial fluid volume resuscitation, the patient's urine output has been 30 mL/hr for the past 3 hours. Which order by the health care provider should the nurse question?
Give hydrocortisone (Solu-Cortef) 100 mg IV.
Administer furosemide (Lasix) 40 mg IV.
Increase normal saline infusion to 250 ml/hr.
Use norepinephrine to keep systolic BP above 90 mm Hg.
The Correct Answer is B
B. Administering furosemide, a loop diuretic, to a patient in septic shock with low urine output could exacerbate hypovolemia and worsen organ perfusion. It could further reduce preload, exacerbating hypotension, and impairing cardiac output. Loop diuretics are typically contraindicated in hypovolemic shock.
A. Corticosteroids such as hydrocortisone can help improve vascular tone and responsiveness to vasopressors. Given the patient's clinical presentation and lack of response to initial fluid resuscitation, administering hydrocortisone is appropriate.
C. Increasing the fluid infusion rate can help restore intravascular volume and improve organ perfusion. However, caution should be exercised to avoid fluid overload and pulmonary edema.
D .Norepinephrine is a vasopressor commonly used to increase systemic vascular resistance and improve blood pressure in septic shock. It helps maintain perfusion pressure to vital organs, thereby supporting organ function.

Correct Answer is B
Explanation
B. Tachycardia is a compensatory mechanism aimed at increasing cardiac output and maintaining tissue perfusion. In response to decreased perfusion, the body increases heart rate to improve circulation and oxygen delivery to tissues.
A. Hypokalemia, or low potassium levels, is not typically associated with the compensatory stage of shock. Instead, electrolyte imbalances may develop later in the progression of shock due to tissue hypoperfusion and metabolic disturbances.
C. Mottled skin, characterized by patchy discoloration due to uneven blood flow, is more commonly seen in the progressive or irreversible stages of shock. It indicates significant tissue hypoperfusion and impaired microcirculation, rather than the compensatory stage
D. This blood pressure reading is within the normal range and may be maintained during the compensatory stage of shock. Initially, blood pressure may be maintained or only slightly decreased due to compensatory mechanisms such as vasoconstriction. However, blood pressure can decrease further as shock progresses beyond the compensatory stage.
Correct Answer is A
Explanation
A In atrial fibrillation (AF), the electrical activity in the atria is chaotic, leading to an irregularly irregular ventricular response. As a result, the pulse felt at the radial artery will be irregular, with no discernible pattern. The irregularity is a hallmark feature of AF and is often described as "irregularly irregular."
B Bounding pulses are characterized by a strong and forceful pulsation felt at the arterial pulse sites. In atrial fibrillation, the irregular and rapid ventricular response can lead to an increased stroke volume and forceful contraction of the left ventricle during diastole, resulting in bounding pulses. However, bounding pulses are not typically associated with atrial fibrillation; they are more commonly seen in conditions such as aortic regurgitation or hyperdynamic circulation.
C In some cases of atrial fibrillation, especially if the ventricular rate is very rapid or irregularly irregular, the pulse may not be palpable due to the inconsistent ventricular contractions.
However, in most cases of atrial fibrillation, a pulse is palpable, albeit irregular.
D Atrial fibrillation can result in a rapid ventricular response, leading to a fast heart rate. However, the pulse rate can vary widely among individuals with atrial fibrillation. While some may have a rapid heart rate (tachycardia), others may have a slower heart rate (bradycardia), depending on factors such as concomitant medications, autonomic tone, and the presence of underlying heart disease.
