The nurse is caring for a client in the ED just arriving with severe chest pain, shortness of breath, diaphoresis, and jugular distention. What will be the most important thing the nurse will do within the first 10 minutes?

A. Ascending edema:

Ascending edema, also known as dependent edema, is typically associated with right-sided heart failure rather than left-sided heart failure. In right-sided heart failure, the heart's ability to pump blood to the lungs for oxygenation is compromised, leading to fluid backup in the systemic circulation. This fluid accumulates in the dependent areas of the body, such as the lower extremities (legs and ankles), causing swelling that can ascend upwards if left untreated. However, ascending edema is not a characteristic finding in left-sided heart failure, where pulmonary congestion and orthopnea are more common manifestations.

B. The client has no desire to eat:

While decreased appetite can occur in heart failure due to various factors such as fluid retention, abdominal bloating, or medication side effects, it is not a specific hallmark of left-sided heart failure. Symptoms such as fatigue, dyspnea (shortness of breath), orthopnea (difficulty breathing while lying flat), and paroxysmal nocturnal dyspnea (PND) are more commonly associated with left-sided heart failure. These symptoms result from the impaired function of the left ventricle, leading to pulmonary congestion and inadequate oxygenation.

C. The client sleeps on three pillows at night:

This choice is the correct answer. Sleeping on three pillows at night is a classic manifestation of orthopnea, a condition commonly seen in left-sided heart failure. Orthopnea refers to difficulty breathing while lying flat, which is alleviated by elevating the head and upper body with multiple pillows or sleeping in a semi-upright position. Orthopnea occurs due to the redistribution of fluid from the legs and lower body to the lungs when lying down, resulting in pulmonary congestion and respiratory distress.

D. The client has a five-pound weight gain:

Weight gain is a common symptom of fluid retention in heart failure; however, a specific weight gain of five pounds alone may not be indicative of left-sided heart failure without considering other clinical signs and symptoms. In heart failure, weight gain is often associated with fluid overload, which can lead to edema, dyspnea, orthopnea, and other signs of congestion. It's important to assess the client comprehensively for fluid status, including evaluating for edema, respiratory symptoms, and changes in weight over time, to determine the underlying cause of weight gain.

To calculate how many milliliters (mL) of metoprolol 1 mg/mL solution should be administered to deliver a 5 mg IV bolus dose, you can use the following formula:

Dose (mL) = Desired dose (mg) / Concentration (mg/mL)

In this case:

Desired dose = 5 mg

Concentration = 1 mg/mL

Dose (mL) = 5 mg / 1 mg/mL = 5 mL

Therefore, the nurse should administer 5 mL of metoprolol 1 mg/mL solution per dose to deliver a 5 mg IV bolus for heart rate control.
