A urine specific gravity of 1.010 falls within the normal physiological range of 1.005 to 1.030 and suggests adequate renal hydration. In a state of severe dehydration, the nurse expects a markedly elevated specific gravity, typically ≥ 1.030, as the kidneys maximize water reabsorption. This finding would actually contradict a diagnosis of severe dehydration, as it indicates the urine is not being concentrated to preserve volume.

Normal skin turgor is a sign of adequate fluid balance where the dermal and subcutaneous layers remain elastic and hydrated. In severe dehydration, the nurse would instead observe "tenting," where the skin fails to return to its original position after being pinched. Because this choice represents a healthy finding, it cannot be used to indicate a complication as severe as pathological dehydration in a hyperemesis client.

A heart rate of 72 beats per minute is a normal resting find for most adults and indicates cardiovascular stability. Severe dehydration typically triggers a compensatory tachycardia (HR > 100 bpm) as the sympathetic nervous system attempts to maintain cardiac output in the face of low stroke volume. The absence of an elevated pulse suggests that the circulating volume is currently sufficient to meet the body's metabolic and hemodynamic demands.

A stroke typically presents with focal neurological deficits, such as hemiparesis or facial drooping, rather than a global state of confusion. While dehydration can increase the risk of thrombosis, the specific combination of ataxia and encephalopathy in a vomiting patient is much more characteristic of a metabolic deficiency. Stroke symptoms usually appear suddenly and are related to a specific vascular territory in the brain.

A migraine disorder is characterized by severe, often unilateral, throbbing headaches accompanied by photophobia and phonophobia. While migraines can cause nausea and vomiting, they do not cause a persistent unsteady gait or global cognitive confusion between episodes. The primary pathology of a migraine is vascular and neurological irritability rather than the systemic micronutrient depletion seen in hyperemesis.

A seizure disorder involves paroxysmal, uncontrolled electrical activity in the brain that results in altered consciousness or convulsions. While a post-ictal state can include confusion, a persistent ataxic gait is not a standard feature of chronic epilepsy. Seizures in a pregnant client with hyperemesis would more likely be a result of severe hyponatremia or magnesium imbalance rather than thiamine loss.

Advising the client that symptoms are expected in pregnancy is a form of dismissal that trivializes a potentially life-threatening condition. While "morning sickness" is common, hyperemesis gravidarum is a pathological state that requires medical hospitalization. This statement minimizes the client's physical suffering and can lead to a breakdown in the therapeutic relationship, as the client may feel the nurse does not understand the severity of the illness.

Minimizing discussion of emotional distress is counterproductive and can exacerbate the psychological burden of the disease. Unaddressed anxiety and depression can worsen the physiological perception of nausea through the gut-brain axis. Ignoring the emotional components of hyperemesis fails to provide holistic care and misses critical opportunities to screen for serious mental health complications like post-traumatic stress disorder related to the pregnancy.

Encouraging the client to avoid family involvement is inappropriate because social support is a vital protective factor during high-risk pregnancies. Family members can provide emotional comfort, assist with activities of daily living, and help manage the household while the client is incapacitated. Isolation can lead to increased maternal anxiety and depression, whereas a strong support system is associated with better psychological outcomes for the mother and family unit.
