A nurse in the emergency department is monitoring a client who is receiving dopamine to treat hypovolemic shock. Which of the following findings should the nurse identify as an indication for increasing the client's dopamine dosage?

Heart rate 60/min

Oxygen saturation 95%

Blood pressure 90/50 mm Hg

Respiratory rate 14/min

Answer and Explanation

The Correct Answer is C

Choice A reason: A heart rate of 60/min is within the normal range for an adult, and while it may be considered on the lower end, it is not in itself an indication to increase dopamine dosage. Dopamine is used to increase heart rate and cardiac output, but a rate of 60/min does not typically warrant an increase in dosage unless accompanied by other signs of inadequate perfusion.

Choice B reason: An oxygen saturation of 95% is within the normal range for arterial blood gases and is not an indication to increase dopamine dosage. Oxygen saturation reflects the percentage of hemoglobin binding sites in the bloodstream occupied by oxygen.

Choice C reason: A blood pressure of 90/50 mm Hg is considered low and can be an indication for increasing the dopamine dosage in a client with hypovolemic shock. Dopamine increases blood pressure by vasoconstriction and increasing cardiac output, which is critical in managing shock.

Choice D reason: A respiratory rate of 14/min is within the normal range for adults and is not an indication to increase dopamine dosage. The respiratory rate should be monitored for changes that could indicate worsening of the client's condition, but on its own, it does not dictate adjustments to dopamine therapy.

Correct Answer is C

Explanation

Choice A reason : A tongue blade should not be placed in the mouth during a seizure as it can cause injury or obstruct the airway.

Choice B reason: An NG tube, or nasogastric tube, is not typically required in the immediate management of seizures and should not be inserted during an active seizure due to the risk of injury.

Choice C reason: An oral airway may be used to maintain a patent airway during a postictal state if the client is unable to maintain their own airway.

Choice D reason: Wrist restraints are not routinely recommended for clients with seizure disorders as they can cause injury during a seizure. Safe environment and proper positioning are preferred to prevent injury.

A. Epinephrine B. Furosemide C. Nitroprusside D. Desmopressin

Correct Answer is D

Explanation

Choice A reason: Epinephrine is primarily used in emergency situations for its vasoconstrictive and bronchodilatory effects, particularly in cases of anaphylaxis or cardiac arrest. It is not typically used to manage symptoms associated with brainstem contusions or to regulate urinary output.

Choice B reason: Furosemide is a loop diuretic commonly prescribed to reduce fluid retention in conditions such as heart failure or renal disease. Given that the client has already produced a large volume of urine (4,000 mL in 24 hours, which is above the normal range of 800 to 2,000 milliliters per day), administering furosemide would not be appropriate as it would likely exacerbate the excessive urinary output.

Choice C reason: Nitroprusside is a potent vasodilator used to treat acute hypertensive crises. It has no role in the management of thirst or regulation of urinary output and is not indicated for the treatment of brainstem contusions.

Choice D reason: Desmopressin is a synthetic analogue of the naturally occurring antidiuretic hormone vasopressin. It is used to treat conditions characterized by excessive urination, such as diabetes insipidus, and to manage polyuria and polydipsia (excessive thirst) following head trauma or surgery in the pituitary region. In the context of a brainstem contusion with a reported high urinary output, desmopressin would be the appropriate medication to prescribe to reduce urine volume and address the client's thirst.
