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
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 D
Explanation
Choice A reason: Moving the cane 2 feet ahead is too far and can cause imbalance or a fall. The cane should be moved a short distance ahead, about the length of one natural step.
Choice B reason: Holding the cane with the right hand is correct for someone with left-sided weakness. The cane should be used on the stronger side of the body to provide support for the weaker side.
Choice C reason : Taking a step with the left foot first is not correct because the weaker leg should be advanced to the cane to ensure stability and support when moving.
Choice D reason: Advancing the weaker leg forward to the cane is correct. The cane provides support for the weaker leg, helping to maintain balance as the client walks.
Correct Answer is C
Explanation
Choice A reason: A respiratory rate of 24/min is slightly higher than the normal range (12-20 breaths per minute) and does not necessarily indicate the effectiveness of furosemide in treating pulmonary edema.
Choice B reason: Adventitious breath sounds, such as crackles or wheezes, are often present in pulmonary edema and would not indicate that the furosemide is effective. The resolution of these sounds would be a better indicator of improvement.
Choice C reason: Weight loss of 1.8 kg (4 lb) in the past 24 hours likely indicates a reduction in fluid retention, which is a desired effect of furosemide in the treatment of pulmonary edema. This diuretic effect reduces the fluid overload, thereby improving the symptoms of pulmonary edema.
Choice D reason: An elevation in blood pressure is not an expected outcome of effective furosemide therapy for pulmonary edema. Furosemide is a diuretic and would more likely lead to a reduction in blood pressure due to fluid loss.
