Norepinephrine has been prescribed for a patient who was admitted with dehydration and hypotension. Which data indicate that the nurse should consult with the health care provider before starting the norepinephrine?
The patient's central venous pressure is 3 mm Hg.
The patient is receiving low dose dopamine.
The patient is in sinus tachycardia at 120 beats/min.
The patient has had no urine output since admission.
The Correct Answer is A
A Adequate fluid administration is essential before giving vasopressors to patients with hypovolemic shock. The patient’s low central venous pressure indicates a need for more volume replacement. The other patient data are not contraindications to norepinephrine administration.
B Low dose dopamine is not a contraindication to epinephrine administration.
C A sinus tachycardia is not a contraindication to epinephrine administration
D Lack of urine output is not a contraindication to epinephrine administration

Correct Answer is C
Explanation
C Atrial fibrillation (AF) is characterized by rapid, irregular electrical activity in the atria, leading to an irregularly irregular ventricular response. AF often results in palpitations, fatigue, and dizziness due to the irregular heart rhythm and inefficient cardiac output. A significant pulse deficit may also be present due to the irregularity of the ventricular response compared to the atrial activity. Given the sudden onset of irregular palpitations, fatigue, dizziness, and a significant pulse deficit, atrial fibrillation is a likely dysrhythmia in this scenario.
A First-degree AV block is characterized by a prolonged PR interval on the electrocardiogram (ECG), indicating delayed conduction between the atria and ventricles. While it can indicate conduction system abnormalities, it typically does not result in rapid or irregular palpitations, fatigue, or dizziness.
Therefore, it is less likely to be the cause of the client's symptoms.
B Sinus tachycardia is characterized by a rapid heart rate originating from the sinus node, typically with a regular rhythm. While sinus tachycardia can cause palpitations and fatigue, it is less likely to result in an irregular heart rate with a significant pulse deficit. Therefore, it is less likely to be the cause of the client's symptoms.
D Sinus bradycardia is characterized by a slow heart rate originating from the sinus node. While sinus bradycardia can cause fatigue and dizziness, it typically does not result in a rapid or irregular heart rate. Therefore, it is less likely to be the cause of the client's symptoms.
Correct Answer is B
Explanation
B. Checking the left hand for pallor can help assess peripheral perfusion and determine if there is adequate blood flow distal to the arterial line insertion site. Pallor in the left hand could indicate decreased perfusion, which may contribute to the low-pressure alarm.
A. Re-zeroing the monitoring equipment may be necessary to ensure accurate pressure readings. However, it should not be the first action taken when the low-pressure alarm sounds. Before re-zeroing, the nurse should assess the patient's condition to ensure there are no immediate issues affecting arterial pressure.
C. Fast flushing the arterial line is not typically the first action to take when the low-pressure alarm sounds. Fast flushing may increase the risk of dislodging the catheter or causing air embolism if there is a problem with the line.
D. Assessing for dysrhythmias should be part of the overall assessment but may not be the first action taken in response to the alarm.
