A nurse is preparing to titrate a continuous nitroprusside infusion for a client. The nurse should plan to titrate the infusion according to which of the following assessments?
Blood pressure
Stroke volume
Cardiac output
Urine output
The Correct Answer is A
Choice A Reason:
Blood pressure is correct. Nitroprusside is a medication used to lower blood pressure in conditions such as hypertensive emergencies. It's titrated based on blood pressure readings, with the goal of achieving the desired target blood pressure range as directed by the healthcare provider. The nurse would monitor the client's blood pressure closely and adjust the infusion rate accordingly to achieve the prescribed blood pressure parameters.
Choice B Reason:
Stroke volume is incorrect. While stroke volume (the amount of blood ejected by the heart with each contraction) is important in assessing heart function, it's not directly used to titrate a nitroprusside infusion. Nitroprusside primarily acts as a vasodilator to reduce blood pressure, rather than affecting stroke volume.
Choice C Reason:
Cardiac output is incorrect. Cardiac output (the volume of blood pumped by the heart per minute) is also a crucial measure of heart function, but adjusting a nitroprusside infusion based on cardiac output is not a common practice. Nitroprusside's primary action is to dilate blood vessels, impacting blood pressure regulation more directly than cardiac output.
Choice D Reason:
Urine output is incorrect. While urine output is an important indicator of renal function and overall fluid balance, it is not typically used as the main parameter for titrating nitroprusside. Nitroprusside's primary effect is on vasodilation and blood pressure control rather than directly impacting urine output.

Correct Answer is C
Explanation
Choice A Reason:
"I will have my partner tilt their head back while I am instilling the drops." Is incorrect. Tilting the head back is not typically recommended for administering optic medication as it might cause the medication to flow out instead of remaining in the ear canal.
Choice B Reason:
"I will make sure the solution is cool prior to instilling the drops." Is incorrect. The temperature of the solution usually doesn't need to be adjusted before instilling optic drops unless directed otherwise by specific medication instructions or healthcare provider guidance.
Choice C Reason:
"I will pull the pinna upward and outward prior to instilling the drops." Is correct statement. Pulling the pinna (outer ear) upward and outward helps straighten the ear canal in adults, facilitating the proper administration of optic (ear) drops. This action helps ensure that the medication reaches the ear canal effectively.
Choice D Reason:
"I will have my partner lie down on their back while I am instilling the drops." Is incorrect statement.
Having the partner lie down on their back might not be necessary for administering optic medication and might not be the optimal position for effective instillation.
Correct Answer is D
Explanation
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.
