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

Explanation
A. Chronic hypertension is a significant risk factor for the development of various cardiac diseases, including coronary artery disease, left ventricular hypertrophy, heart failure, and arrhythmias. The increased workload on the heart caused by hypertension can lead to myocardial remodeling, impaired cardiac function, and ultimately heart disease.
B. Chronic hypertension can cause damage to the kidneys over time, leading to renal insufficiency or chronic kidney disease. The elevated blood pressure damages the delicate blood vessels in the kidneys, impairing their ability to filter waste products and regulate fluid and electrolyte balance. Persistent hypertension can ultimately lead to kidney dysfunction and renal failure.
C. Hypertension is a major risk factor for the development of stroke, particularly ischemic stroke (caused by a blockage in a blood vessel supplying the brain) and hemorrhagic stroke (caused by bleeding into the brain). Chronic hypertension can damage blood vessels in the brain, leading to the formation of blood clots or weakening of vessel walls, increasing the risk of stroke.
E. Chronic hypertension is a significant risk factor for the development of atrial fibrillation, a type of irregular heart rhythm characterized by rapid and chaotic electrical activity in the upper chambers of the heart (atria). The structural changes in the heart caused by hypertension, such as left atrial enlargement and fibrosis, can predispose individuals to atrial fibrillation.
D. Familial hypercholesterolemia is a genetic disorder characterized by high levels of LDL cholesterol in the blood. While chronic hypertension itself does not directly cause familial hypercholesterolemia, hypertension and hypercholesterolemia are often comorbid conditions that contribute to cardiovascular risk. Both conditions can lead to atherosclerosis, increasing the risk of heart disease and stroke.
F. Isolated systolic hypertension refers to elevated systolic blood pressure with normal diastolic blood pressure. While isolated systolic hypertension itself is a manifestation of hypertension, it is not a direct result of end-organ damage. However, if left untreated, isolated systolic hypertension can lead to complications such as stroke, heart failure, and kidney disease, which are consequences of end-organ damage from chronic hypertension.

Explanation
In respiratory acidosis, there is an accumulation of carbon dioxide (CO2) in the blood due to inadequate ventilation, leading to an increase in the partial pressure of arterial carbon dioxide (PaCO2) and a decrease in pH.
This is often caused by conditions that impair ventilation, such as airway obstruction, respiratory muscle weakness, lung diseases (e.g., chronic obstructive pulmonary disease, pneumonia), or central nervous system depression (e.g., drug overdose, head injury).
Management of respiratory acidosis include bronchodilators, sodium bicarbonate, adequate ventilation, and treatment of underlying causes.
