A charge nurse is teaching a newly licensed nurse about administering heparin to a client. Which of the following statements by the newly licensed nurse indicates an understanding of the teaching?

Choice A Reason:
Furosemide is not correct. Furosemide is a diuretic used to treat conditions like heart failure and edema by increasing urine output. It is not a contraindication for sildenafil. However, it's essential to monitor blood pressure when these medications are used together, as both can potentially lower blood pressure.
Choice B Reason:
Albuterol is not correct. Albuterol is a bronchodilator commonly used to treat asthma and other respiratory conditions. It doesn't have direct contraindications with sildenafil for erectile dysfunction. Although both medications can cause some cardiovascular effects, they are not typically considered contraindications for each other.
Choice C Reason:
Indomethacin is not correct. Indomethacin is a nonsteroidal anti-inflammatory drug (NSAID) used to reduce inflammation and pain. While it can have effects on blood pressure and the cardiovascular system, it is not a direct contraindication for sildenafil specifically for erectile dysfunction.
Choice D Reason:
Nitroglycerin is correct. Nitroglycerin is a contraindication for sildenafil. Both medications can cause a significant drop in blood pressure. When taken together, they can potentiate each other's effects, leading to a severe decrease in blood pressure, which can be dangerous and potentially life-threatening. Therefore, individuals using nitroglycerin or any nitrate medications should not take sildenafil or other medications for erectile dysfunction due to the risk of hypotension (dangerously low blood pressure).

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 reduce the risk of bleeding or hematoma formation, especially with subcutaneous injections. This practice aids in minimizing bleeding at the injection site.
