C. its use in hypovolemic shock is generally not appropriate because the primary treatment for hypovolemic shock is fluid resuscitation to address the volume loss.

A. Dopamine is often used in neurogenic shock to increase systemic vascular resistance and improve blood pressure. Therefore, dopamine is an appropriate choice for the management of hypotension due to neurogenic shock.

B. Dopamine is commonly used in septic shock to improve cardiac output and systemic vascular resistance. It helps to support blood pressure and perfusion in septic shock patients.

D. It is indicated for cardiogenic shock as it increases cardiac contractility.

Correct Answer is B

Explanation

B. This is advised to prevent hypoxemia, which can manifest as tachycardia and arrhythmia, conditions indicated by an increased and irregular heart rate. Pre-oxygenation helps maintain adequate oxygen levels in the blood, which can be compromised during the suctioning process.

A. Obtaining a cardiology consult might be necessary if the client's heart rate increases and becomes irregular. However, it's not the immediate action the nurse should take. This option is more appropriate for addressing the underlying cause of the client's dysrhythmia rather than the immediate management during suctioning.

C. Suctioning the client less frequently might be appropriate if the client's response to suctioning is causing distress or physiological changes like increased heart rate. However, if suctioning is necessary due to secretions in the airway, simply reducing the frequency might not be sufficient to address the client's cardiovascular response.

D. Administering an antidysrhythmic medication should be considered if the client's heart rate increases and becomes irregular during or after suctioning, especially if the dysrhythmia persists or worsens.

However, this should be done under the guidance of a healthcare provider and after assessing the client's overall condition, including potential causes of the dysrhythmia.

A. The patient's central venous pressure is 3 mm Hg. B. The patient is receiving low dose dopamine. C. The patient is in sinus tachycardia at 120 beats/min. D. The patient has had no urine output since admission.

Correct Answer is A

Explanation

A Adequate fluid administration is essential before giving vasopressors to patients with hypovolemic shock. The patient’s low central venous pressure indicates a need for more volume replacement. The other patient data are not contraindications to norepinephrine administration.

B Low dose dopamine is not a contraindication to epinephrine administration.

C A sinus tachycardia is not a contraindication to epinephrine administration

D Lack of urine output is not a contraindication to epinephrine administration
