A nurse is caring for a client who is receiving 0.9% sodium chloride solution to treat dehydration. Which of the following findings should the nurse identify as an adverse effect of the solution?

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:
Ondansetron is incorrect. Ondansetron is an anti-nausea medication commonly used in cancer patients to manage nausea and vomiting, often caused by chemotherapy. It's not typically contraindicated or known to interact significantly with morphine administered via a PCA pump. This combination is often used to manage both pain and associated symptoms in cancer patients.
Choice B Reason:
Acetaminophen is incorrect. Acetaminophen is a pain reliever and fever reducer that doesn't typically interact significantly with morphine administered via a PCA pump. It's often used concurrently with other pain medications to manage discomfort in cancer patients. There isn't a known significant interaction between acetaminophen and morphine when used appropriately.
Choice C Reason:
Nalbuphine is correct. Nalbuphine is an opioid analgesic, similar to morphine, and administering it concurrently with morphine could potentially lead to opioid overdose or increased risk of opioid-related side effects such as respiratory depression. Thus, it's crucial to clarify with the provider whether there might be a potential interaction or if both medications are indeed necessary in this specific clinical scenario.
Choice D Reason:
Insulin glargine is incorrect. Insulin glargine is a long-acting insulin used to manage blood sugar levels in individuals with diabetes. While its interaction with morphine isn't typically a concern, it's essential to monitor blood sugar levels closely in individuals receiving opioids like morphine, as opioids can affect glucose metabolism and may necessitate adjustments in insulin dosage.
