The nurse administering the phosphodiesterase inhibitor milrinone (Primacor) recognizes that this drug will have a positive inotropic effect. Which result reflects this effect?

Correct Answer: C

Rationale: Milrinone is a phosphodiesterase inhibitor that works by increasing the levels of cyclic adenosine monophosphate (cAMP) within cardiac myocytes. This leads to enhanced calcium influx into the cells, ultimately resulting in increased force of cardiac contractions (positive inotropic effect). This increased contractility helps improve cardiac output without necessarily increasing heart rate or affecting blood vessel dilation.

Correct Answer: B

Rationale: The correct response is to inform the patient that the medication, likely an antiarrhythmic agent such as digoxin immune fab (Digibind), helps to convert the irregular heart rhythm caused by digoxin toxicity to a more normal rhythm. This explanation provides a clear understanding of why the medication is being administered in cases of digoxin toxicity. It is important for the nurse to educate the patient about the purpose of the medication and how it will help manage the symptoms of digoxin toxicity.

Correct Answer: D

Rationale: Acetaminophen is not an opioid or NSAID. It is a pain reliever and fever reducer, but it works in a different way compared to opioids and NSAIDs. Unlike opioids, acetaminophen does not have the same risk of physical dependence or addiction. And unlike NSAIDs, acetaminophen does not have anti-inflammatory properties. It is often used for mild to moderate pain relief and as a fever reducer. Be cautious when taking acetaminophen, as high doses can be harmful to the liver.

Correct Answer: C

Rationale: A common side effect of Heparin, which is an anticoagulant medication, is the risk of bleeding. Heparin works by preventing the formation of blood clots, which can lead to a bleeding risk as it inhibits the normal clotting process. Patients taking Heparin should be monitored closely for signs of bleeding, such as easy bruising, prolonged bleeding from minor cuts, or blood in the urine or stools. It is important for healthcare providers to closely monitor patients on Heparin therapy and adjust the dosage as needed to minimize the risk of excessive bleeding.

Correct Answer: D

Rationale: It is important to monitor ins and outs with patients using ACE inhibitors to assess for decreased blood pressure. ACE inhibitors are known to lower blood pressure by dilating blood vessels, which can sometimes lead to hypotension (low blood pressure). Monitoring the patient's fluid intake and output helps healthcare providers evaluate the patient's blood pressure response to the medication and make necessary adjustments to prevent complications such as dizziness, falls, or fainting. Regular monitoring is crucial to ensure the patient's safety and optimize the effectiveness of ACE inhibitor therapy.
