Heparin 7,000 units is ordered. Heparin 5,000 units per ml is available. How many milliliters (ml) should the nurse administer?
(Do not round)
The Correct Answer is ["1.4"]
We know that 7,000 units is equivalent to 5,000 units per ml. So, we can set up the proportion:
7,000 units / 5,000 units per ml = x ml / 1 ml x = 7,000 / 5,000
x = 1.4
Therefore, the nurse should administer 1.4 milliliters (ml) of heparin.

Correct Answer is A
Explanation
The lower esophageal sphincter (LES) is a muscular ring located between the esophagus and stomach. Its function is to prevent the backflow of stomach acid and contents into the esophagus. In GERD, the LES becomes weak or relaxed, allowing stomach acid to flow back up into the esophagus, leading to symptoms such as heartburn, regurgitation, and chest pain.
Correct Answer is D
Explanation
Pain and coldness in the fingers following AVG placement can indicate impaired blood flow or compromised circulation to the hand. This may be due to complications such as thrombosis (clot formation), graft malfunction, or decreased arterial perfusion. These symptoms should be taken seriously and promptly communicated to the healthcare provider.
The healthcare provider needs to evaluate the patient's symptoms, assess the AVG, and determine the appropriate course of action. Prompt intervention can help prevent further complications and ensure adequate blood flow to the fingers.
