A nurse is preparing to administer lidocaine via continuous IV infusion at 4 mg/min. Available is lidocaine 2 g dextrose 5% in water 500 mL. The nurse should set the IV pump to deliver how many mL/hr?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A Reason:
. "I will check the client's INR before administering the heparin." Is incorrect. Checking the client's INR (International Normalized Ratio) is essential, but it's more applicable for monitoring anticoagulants like warfarin, not heparin. Heparin's effect is typically monitored via activated partial thromboplastin time (aPTT) or anti-Xa levels, not INR.
Choice B Reason:
"I will aspirate before administering the heparin." Is incorrect. Aspirating before administering heparin injections is not necessary because the medication is given subcutaneously or intravenously and not into a blood vessel.
Choice C Reason:
"I will massage the site after injecting the heparin." Is incorrect. Massaging the site after injecting heparin could increase the risk of bruising or hematoma formation at the injection site. It's generally advised to avoid massaging the area after a heparin injection to prevent tissue trauma.
Choice D Reason:
"I will apply pressure for 1 minute after the injection." Is correct. Applying pressure to the injection site for about a minute after administering heparin helps minimize the risk of bleeding or hematoma formation, especially with subcutaneous injections. This practice aids in reducing bleeding at the injection site.

Choice A Reason:
Oxygen saturation within this range is generally considered adequate and might not directly correlate with the administration of albumin.
Choice B Reason:
Decrease in protein is incorrect. Albumin infusions are meant to supplement protein levels in the blood, so a decrease in protein wouldn't be an expected finding.
Choice C Reason:
Increase in blood pressure is correct. Albumin infusions can potentially help increase blood volume, leading to an increase in blood pressure. In shock, where there's a significant decrease in blood pressure due to reduced circulating volume, administering albumin or other intravenous fluids can help restore blood volume and consequently raise blood pressure towards a more stable range.
Choice D Reason:
PaCO2 of 30 mm Hg is incorrect. PaCO2 levels are related to respiratory function and the amount of carbon dioxide in the blood. While shock can impact various physiological parameters, a PaCO2 level of 30 mm Hg alone might not be directly tied to the administration of albumin in shock.
