Papillary muscle dysfunction, often resulting from myocardial infarction, can lead to mitral insufficiency (mitral regurgitation). The papillary muscles support the mitral valve, and if they are damaged, the valve may not close properly, causing blood to flow backward into the left atrium during systole. This condition is not associated with aortic stenosis, mitral stenosis, or aortic insufficiency. References: = CCRN Exam Handbook, AACN Adult CCRN Certification Review Course

Takotsubo cardiomyopathy, also known as stress-induced cardiomyopathy or "broken heart syndrome," is characterized by transient left ventricular dysfunction often precipitated by significant emotional or physical stress. The key findings of chest pain and ST elevation without significant coronary artery disease, along with left ventricular dysfunction and apical ballooning observed on imaging, are classic for takotsubo cardiomyopathy. This condition is often reversible and is associated with a temporary reduction in the heart's pumping ability, indicated by the reduced ejection fraction (EF) of 35%. References: =

When a physician has attempted to insert a central line multiple times without success, the nurse's responsibility includes ensuring patient safety and advocating for the patient. Continued attempts by the same physician may increase the risk of complications, such as infection or trauma. Therefore, the nurse should suggest that another physician, possibly one with more experience or skill in central line insertion, perform the procedure.

The primary consideration is to ensure that the family understands the unit's visitation policies. While alternative modalities like therapeutic touch can be beneficial, the nurse must adhere to established policies and explain the rationale to the family. This helps maintain the integrity of unit operations and ensures that all patients receive equitable care. Explaining the policies also provides an opportunity to discuss alternative ways to support the patient within the existing framework.

For an oncology patient presenting with hematuria and bleeding from injection sites, reviewing the coagulation panel first is crucial. This test will provide information on the patient's clotting status, helping to identify potential coagulopathies such as disseminated intravascular coagulation (DIC), which is common in cancer patients.
