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 D
Explanation
D. A drop in oxygen saturation may indicate inadequate oxygenation, which could be due to airway obstruction or retained secretions.
A. While audible expiratory wheezes may indicate airway obstruction or secretions, they do not necessarily indicate the need for suctioning in a patient receiving mechanical ventilation.
B. An elevated respiratory rate may suggest increased work of breathing, which could be due to retained secretions or airway obstruction. However, an elevated respiratory rate alone may not always indicate the need for suctioning.
C. The timing of the last suctioning episode is an important consideration when determining the need for suctioning. However, it should not be the sole indicator for when to suction.
Correct Answer is A
Explanation
A. A heart murmur typically indicates turbulent blood flow through a heart valve. This turbulence can occur due to various reasons, such as valve stenosis (narrowing), regurgitation (leakage), or structural abnormalities of the valves. The turbulent flow produces audible sounds that can be heard with a stethoscope during cardiac auscultation.
B. A heart murmur is not caused by blood entering an inflexible chamber. Instead, it is caused by turbulent blood flow through the heart valves. The sound produced by this turbulent flow may vary depending on the underlying pathology of the valve.
C. While heart murmurs can be described based on their characteristics (such as high-pitched or low- pitched), the presence of a heart murmur does not necessarily indicate a narrow valve. Murmurs can occur due to various valve abnormalities, including stenosis (narrowing) or regurgitation (leakage). The pitch and quality of the murmur may vary depending on the underlying pathology and the location of the abnormality.
D. A heart murmur is not typically associated with inflammation around the heart. While inflammation of the heart (such as myocarditis or pericarditis) can cause symptoms and abnormal sounds, these conditions would not be described specifically as a "heart murmur."
