To assess a client’s dorsalis pedis pulse, the nurse applies firm pressure over the top of the foot between the extension tendons of the great and first toes, but does not feel a pulsation. Which action should the nurse take next?

Choice A reason: Reviewing pain medications is premature without confirming the cause of grimacing. Pain activates the somatosensory cortex, but grimacing may reflect discomfort, fear, or effort, not necessarily pain. Asking the client clarifies the cause, ensuring appropriate intervention, as medication may be unnecessary if grimacing stems from non-pain issues.

Choice B reason: Asking the client about the grimacing clarifies its cause, as pain denial may reflect cultural or psychological factors. Grimacing involves facial muscle activation, signaling discomfort or effort, processed by the brain’s pain matrix. Direct inquiry ensures accurate assessment, guiding whether pain management or other interventions are needed, making this the first step.

Choice C reason: Administering PRN pain medication without confirming pain risks inappropriate treatment. Grimacing may indicate effort or anxiety, not pain, as denial suggests. Pain medications affect opioid receptors, but unnecessary use can cause sedation or respiratory depression. Asking the client first ensures the intervention matches the underlying issue, avoiding harm.

Choice D reason: Monitoring nonverbal behavior is useful but delays addressing the observed grimacing. Pain or discomfort triggers facial expressions via the limbic system, but denial requires clarification. Asking the client directly provides immediate insight into the cause, enabling targeted care, whereas ongoing observation may miss opportunities for timely intervention.

Choice A reason: Fluid volume deficit is the highest priority, as diarrhea post-stroke causes rapid water and electrolyte loss, risking hypovolemia. Dehydration impairs cellular function, exacerbating neurological deficits and causing hypotension. Immediate fluid replacement restores blood volume, stabilizing vital organs, taking precedence over mobility or caregiver issues, which are less life-threatening.

Choice B reason: Caregiver role strain is significant, as supporting a stroke patient with diarrhea is demanding, but it is not immediately life-threatening. Fluid deficit from diarrhea risks hypovolemic shock, directly impacting the client’s physiological stability. Addressing fluid loss prevents organ failure, making caregiver strain a lower priority after stabilizing the client’s condition.

Choice C reason: Impaired bed mobility, common post-stroke due to hemiparesis, increases complication risks but is secondary to fluid deficit. Diarrhea causes acute fluid loss, reducing blood volume, which can lead to tachycardia and organ hypoperfusion. Managing fluid balance is critical to prevent systemic collapse, prioritizing it over mobility interventions in this acute phase.

Choice D reason: Bowel incontinence (diarrhea) contributes to fluid loss but is a symptom, not the priority problem. Fluid volume deficit, resulting from diarrhea, threatens cardiovascular and renal function by decreasing plasma volume. Addressing fluid replacement prevents life-threatening hypovolemia, making bowel incontinence less urgent than correcting the physiological consequences of fluid loss.
