The nurse is caring for a client who has heart failure with an EF of 40%. The client has a BP of 170/67 with an HR of 60. He currently is in normal sinus rhythm and has an amber urine output of 45ml in the last 3 hours. Which medication would the nurse expect to give first?

Isosorbide PO

Nitroglycerin Drip

Dopamine drip

Normal Saline Bolus

Answer and Explanation

The Correct Answer is D

D Normal saline bolus administration is indicated for hypovolemia or inadequate intravascular volume, which can lead to decreased cardiac output and hypotension. In this scenario, the client has an amber urine output of 45ml in the last 3 hours, indicating decreased urine output and potential hypovolemia. The elevated blood pressure (170/67 mmHg) suggests possible volume overload or fluid retention, but the decreased urine output raises concerns for inadequate intravascular volume. Therefore, administering a normal saline bolus may be the first priority to optimize intravascular volume and improve cardiac output.

A Isosorbide mononitrate is a vasodilator commonly used in the treatment of heart failure and angina. It helps reduce preload and afterload, thereby decreasing the workload on the heart. However, in this scenario, the client's blood pressure is elevated (170/67 mmHg), and there is no indication of acute decompensation or pulmonary congestion. Therefore, isosorbide PO may not be the first priority medication at this time.

B Nitroglycerin is a potent vasodilator commonly used to manage acute heart failure exacerbations and acute coronary syndromes. It helps reduce preload and afterload, improving cardiac output and relieving symptoms of heart failure. In this scenario, the client's blood pressure is elevated, but the heart rate is normal, and there are no signs of acute decompensation. Therefore, initiating a nitroglycerin drip may not be the first priority unless the client develops symptoms of acute decompensation or pulmonary congestion.

C Dopamine is a vasopressor medication that can be used to increase blood pressure and cardiac output in patients with hypotension or shock. However, in this scenario, the client's blood pressure is elevated (170/67 mmHg), and there is no evidence of hypotension. Therefore, initiating a dopamine drip may not be appropriate at this time and could potentially exacerbate hypertension.

Correct Answer is D

Explanation

D Crackles audible at the lung bases indicate the presence of pulmonary edema or fluid accumulation in the alveoli, which can compromise gas exchange and exacerbate respiratory distress. In a patient with ARDS, crackles suggest worsening pulmonary status and may indicate inadequate ventilation or oxygenation despite mechanical ventilation. Therefore, crackles at the lung bases are the most important finding to report to the healthcare provider as they may indicate a need for adjustments to the ventilator settings or additional interventions to optimize respiratory function and prevent further deterioration.

A respiratory rate of 22 breaths/min may be within an acceptable range, particularly considering that the patient is receiving mechanical ventilation. However, any significant deviation from the baseline respiratory rate or signs of respiratory distress, such as increased work of breathing or accessory muscle use, should be closely monitored and reported promptly.

B A heart rate of 106 beats/min may be within an acceptable range, although it is slightly elevated. Tachycardia can occur due to various factors, including pain, anxiety, fever, or hypoxemia. While tachycardia warrants close monitoring, it may not be the most critical finding to report unless it is associated with hemodynamic instability or other concerning symptoms.

C An oxygen saturation of 99% indicates adequate oxygenation, which is reassuring, particularly in a patient with acute respiratory distress syndrome (ARDS). However, oxygen saturation alone may not reflect the adequacy of ventilation or the severity of the underlying lung injury. Therefore, while oxygen saturation should be monitored closely, it may not be the most critical finding to report unless it declines significantly or is accompanied by other concerning symptoms.

Explanation

In respiratory acidosis, there is an accumulation of carbon dioxide (CO2) in the blood due to inadequate ventilation, leading to an increase in the partial pressure of arterial carbon dioxide (PaCO2) and a decrease in pH.

This is often caused by conditions that impair ventilation, such as airway obstruction, respiratory muscle weakness, lung diseases (e.g., chronic obstructive pulmonary disease, pneumonia), or central nervous system depression (e.g., drug overdose, head injury).

Management of respiratory acidosis include bronchodilators, sodium bicarbonate, adequate ventilation, and treatment of underlying causes.
