The nurse is monitoring a client in cardiogenic shock who has been placed on a dobutamine intravenous drip. Which manifestation is a desired response to this medication?
Increased heart rate
Increased urine output
Decreased pain
Decreased blood pressure
The Correct Answer is B
Choice A reason: While dobutamine is a sympathomimetic agent that stimulates beta 1 adrenergic receptors, an increased heart rate or tachycardia is often an adverse effect rather than the primary therapeutic goal. Excessive chronotropic effects can increase myocardial oxygen demand, potentially worsening the underlying ischemia in a patient suffering from cardiogenic shock.
Choice B reason: Dobutamine increases cardiac output by enhancing myocardial contractility, known as positive inotropy. This improvement in systemic perfusion increases renal blood flow and glomerular filtration rate. Consequently, increased urine output serves as a clinical indicator that vital organ perfusion is being successfully restored, which is the primary goal in shock.
Choice C reason: Decreased pain is not a direct pharmacologic effect of dobutamine, as it is not an analgesic. While stabilizing a patient’s hemodynamic status might indirectly lead to improved comfort, the medication is specifically titrated to improve hemodynamic parameters and cardiac performance rather than to manage the patient's pain levels.
Choice D reason: Decreased blood pressure would be a paradoxical and undesired response to dobutamine in the context of cardiogenic shock. Dobutamine aims to support the mean arterial pressure by increasing the stroke volume and cardiac output. A drop in blood pressure would suggest worsening pump failure or an inadequate therapeutic response.

Correct Answer is C
Explanation
Choice A reason: Activating a rapid response is an intervention reserved for clients demonstrating acute physiological decline, such as respiratory failure or pulselessness. While sepsis is a medical emergency, the specific symptoms of headache, heat, and blurry vision more specifically point toward a metabolic derangement like hypoglycemia or hyperglycemia rather than immediate systemic collapse.
Choice B reason: Providing a cool cloth is a comfort measure used to address the symptomatic report of feeling "hot." However, in the hierarchy of nursing clinical judgment, comfort measures are ranked lower than diagnostic assessments that identify the underlying cause of neurological and sensory changes like blurry vision and headache.
Choice C reason: Checking capillary blood glucose is the priority because the reported symptoms (headache, feeling hot, and blurry vision) are classic indicators of glycemic instability. In septic clients, metabolic stress and the inflammatory response often lead to significant fluctuations in blood glucose levels, which must be ruled out immediately to prevent permanent neurological injury.
Choice D reason: Administering acetaminophen is a pharmacological intervention for fever or pain. While appropriate if the client is febrile, it is not the priority action. The nurse must first perform a focused assessment to determine if the symptoms are related to a life-threatening glucose imbalance before treating the symptomatic fever or headache.
Correct Answer is D
Explanation
Choice A reason: Traction must never be removed or interrupted without a specific provider order, as the continuous pull is necessary for bone realignment and the prevention of muscle spasms. Removing weights, even momentarily for repositioning, can cause significant pain, tissue trauma, and loss of fracture reduction.
Choice B reason: Pin care is a specialized nursing task that involves assessing for signs of infection (osteomyelitis) and using specific prescribed solutions, such as chlorhexidine or sterile saline. This task requires clinical judgment and sterile or aseptic technique, which is outside the scope of practice for a UAP.
Choice C reason: While hygiene is a task delegable to the UAP, the formal assessment of skin integrity is the sole responsibility of the registered nurse. The UAP should be instructed to report any redness or breakdown, but the nurse must perform the actual assessment of the client's skin.
Choice D reason: This is a critical safety instruction for the UAP. For traction to be effective, the weights must hang freely and not rest on the floor or the bed frame. If weights are obstructed, the therapeutic tension is lost, which can compromise the stabilization of the musculoskeletal injury.
