A nurse is preparing to administer 0. 9% sodium chloride IV infusion 1000 mL bag at a rate of 200 mL/hr for a client who has rhabdomyolysis The nurse should expect the IV pump to infuse over how many hr?

(Round the answer to the nearest whole number. Use a leading zero if it applies. not use a trailing zero.)

A. At high doses, to treat anaphylaxis: Dopamine is not used to treat anaphylaxis. Anaphylaxis is typically managed with medications such as epinephrine, antihistamines, and corticosteroids.

B. At high doses, to increase cardiac output: Dopamine is a medication commonly used in the treatment of shock, particularly in cases of hypotension. At higher doses, dopamine acts as a positive inotrope and increases cardiac contractility, thereby improving cardiac output and increasing blood pressure.

C. At low doses, to cause increased blood flow to the kidneys: At lower doses, dopamine primarily acts on dopaminergic receptors in the renal vasculature, leading to vasodilation of the renal blood vessels and increased renal perfusion. This can help improve renal blood flow and urine output, making it beneficial in cases of renal hypoperfusion or acute kidney injury.

D. At low doses, to treat anaphylaxis: Dopamine is not used to treat anaphylaxis at any dose. Anaphylaxis is managed with medications such as epinephrine, which acts on multiple receptors to reverse the systemic effects of the allergic reaction.

E. To cause vasoconstriction and increase blood pressure: Dopamine can also cause vasoconstriction, particularly at higher doses. This effect is mediated through its action on alpha-adrenergic receptors, leading to peripheral vasoconstriction and an increase in systemic vascular resistance, which in turn helps increase blood pressure.

A. Respiratory rate and pulse: Albuterol is a bronchodilator medication commonly used to relieve bronchospasm in conditions like asthma and chronic obstructive pulmonary disease (COPD). Monitoring the patient's respiratory rate and pulse is essential to assess the response to the medication and any potential adverse effects.

B. Pulse oximetry: Albuterol helps to open the airways and improve oxygenation in patients with bronchospasm. Monitoring oxygen saturation using pulse oximetry provides valuable information about the patient's respiratory status and response to treatment.

C. Capillary refill: Capillary refill is typically assessed to evaluate peripheral perfusion and circulation. While it is an important assessment in certain clinical situations, it is not directly related to monitoring the response to albuterol administration.

D. Glucose: Glucose monitoring is not typically indicated after administering albuterol nebulizer unless the patient has a history of diabetes or there are specific concerns regarding glucose levels.

E. Lung sounds: Assessing lung sounds before and after administering albuterol helps to evaluate the effectiveness of the medication in relieving bronchospasm. Improvement in lung sounds, such as decreased wheezing or clearer breath sounds, indicates a positive response to treatment.
