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 : Changing the transparent membrane dressing daily is not necessary unless it's soiled or compromised. The dressing is typically changed every 7 days or per institutional policy to reduce the risk of infection.
Choice B reason: Using a non-coring needle is not applicable for PICC lines as they are designed for use with a luer-lock syringe for medication administration and flushing.
Choice C reason : Maintaining a continuous IV infusion is not required for a PICC line unless clinically indicated. Intermittent use is common for medication administration, and the line should be flushed before and after use to maintain patency.
Choice D reason : Flushing the catheter with a 0.9% sodium chloride solution after each use is the correct action. This helps to maintain catheter patency and prevent occlusion.
Correct Answer is C
Explanation
Choice A reason: Decreased urinary output is not a direct indicator of morphine's effectiveness in acute heart failure. While morphine can lead to urinary retention, this is generally considered a side effect rather than an intended therapeutic outcome.
Choice B reason: Emesis, or vomiting, of 250 mL is not an indication of morphine's effectiveness. In fact, nausea and vomiting are common side effects of morphine and other opioids. If emesis occurs, it may necessitate further intervention.
Choice C reason: Decreased anxiety is a sign that the morphine is effective. Morphine has anxiolytic properties, meaning it can help alleviate anxiety, which is beneficial in acute heart failure where anxiety can exacerbate symptoms like shortness of breath.
Choice D reason: An increased respiratory rate to 26/min is not an indication of morphine's effectiveness and is a cause for concern. Morphine can depress the respiratory system, and an increased respiratory rate may indicate compensation for hypoxemia or the onset of adverse effects.
