Correct Answer is B

Explanation

A. I will check the client's INR before administering the heparin:
Checking the International Normalized Ratio (INR) is more relevant for monitoring the effects of warfarin, not heparin. Heparin is typically monitored by activated partial thromboplastin time (aPTT) or anti-Xa levels.
B. "I will apply pressure for 1 minute after the injection:"
Applying gentle pressure to the injection site for about 1 minute after administering heparin is appropriate to prevent bleeding or bruising. Since heparin is an anticoagulant, there's an increased risk of bleeding at the injection site.
C. I will massage the site after injecting the heparin:
Massaging the site after injecting heparin is not recommended. It can increase the risk of hematoma formation. After subcutaneous injection, it is generally advised to avoid massaging the site.
D. I will aspirate before administering the heparin:
Aspiration is not recommended when administering heparin subcutaneously, as it can increase the risk of tissue damage and bruising. The nurse should inject the heparin without aspirating.

A. Stroke volume B. Urine output C. Blood pressure D. Cardiac output

Correct Answer is C

Explanation

A. Stroke volume: While stroke volume is an important parameter in assessing cardiac function, it may not directly guide the titration of nitroprusside infusion. Blood pressure is a more immediate indicator of the drug's effect on vasodilation.
B. Urine output: Nitroprusside primarily affects the vascular system and is not directly associated with urine output. Monitoring urine output is crucial in assessing renal function, but it is not the primary parameter for titrating a nitroprusside infusion.
C. Blood pressure (Correct Answer): Nitroprusside acts as a direct vasodilator, and its primary effect is on blood vessels, leading to a reduction in blood pressure. Therefore, monitoring blood pressure is essential to titrate the infusion to achieve the desired therapeutic effect.
D. Cardiac output: While nitroprusside's vasodilatory effect may influence cardiac output indirectly, blood pressure is a more immediate and specific parameter to guide the titration of the infusion. Nitroprusside is often titrated to reach a target blood pressure range in hypertensive emergencies.
