The nurse is caring for a client with aortic valve regurgitation. Which finding is most important for the nurse report to the healthcare provider?

A. A client with a subdural hematoma experiencing a significant change in blood pressure requires close monitoring and potentially urgent intervention. This patient’s condition is unstable and requires the assessment and clinical judgment of an RN, not a PN.

B. A client in myxedema coma with worsening hypotension is critically ill. The PN may assist with basic care, but managing hemodynamic instability in a life-threatening endocrine emergency requires RN-level assessment and intervention.

C. This is the most appropriate assignment for the PN. The client has viral meningitis with a mild temperature increase, indicating a relatively stable condition that requires monitoring and routine care rather than immediate complex interventions. The PN can safely perform tasks such as vital signs monitoring, basic neurological checks, and reporting changes to the RN.

D. A client with diabetic ketoacidosis (DKA) whose Glasgow Coma Scale score has decreased from 10 to 7 is showing signs of neurological deterioration and severe metabolic instability. This is an urgent, high-risk situation requiring RN-level assessment, critical thinking, and potentially rapid interventions such as fluid resuscitation, electrolyte replacement, and airway management. The PN should not be assigned this patient.

A. Nitroglycerin is highly susceptible to the "first-pass effect," meaning if it is swallowed or chewed and enters the digestive system, the liver will metabolize and inactivate it before it reaches the heart. It must be administered sublingually (under the tongue) to be absorbed directly into the systemic circulation through the oral mucosa.

B. Nitroglycerin is a potent vasodilator. A common side effect is a sudden drop in blood pressure (orthostatic hypotension), which can cause dizziness, syncope (fainting), and falls. Sitting or lying down before taking the medication ensures patient safety. Additionally, resting reduces the oxygen demand on the heart.

C. Anginal pain often occurs during physical exertion or emotional stress (as seen when the patient was mowing the lawn). Immediate access to the medication is critical to stop the progression of ischemia and prevent myocardial infarction.

D. If the pain does not subside after the first dose, it may indicate a myocardial infarction (heart attack) rather than stable angina. Timely activation of Emergency Medical Services (EMS) is the most critical step in reducing heart muscle damage.

E. In the event the patient becomes unconscious or unresponsive, a medical alert bracelet provides first responders with vital information regarding his cardiac history and medications, allowing for faster and more accurate emergency treatment.

F. This statement contains two errors. First, the interval between doses should be 5 minutes, not 10. Second, the patient should not wait to take three doses before calling 911. Current guidelines suggest calling 911 if pain is unrelieved or worsening 5 minutes after the first dose.

G. Sublingual nitroglycerin typically begins to work within 1 to 3 minutes. Waiting 5 minutes allows enough time for the medication to reach peak effect before deciding if an additional dose or emergency intervention is required.
