A nurse is assisting with the care of a client who is at 30 weeks of gestation and has tuberculosis. Which of the following actions should the nurse take?

A. Hypertension: Clients experiencing diabetic ketoacidosis (DKA) are more likely to present with hypotension rather than hypertension due to dehydration caused by osmotic diuresis. Volume depletion significantly lowers blood pressure rather than raising it in the setting of DKA.

B. Fruity breath odor: A fruity or acetone-like breath odor is a hallmark sign of DKA. It results from the accumulation of ketones, particularly acetone, in the blood, which the body attempts to eliminate through the lungs, giving the breath its characteristic sweet or fruity smell.

C. Protruding eyeballs: Protruding eyeballs, or exophthalmos, are associated with hyperthyroidism, particularly Graves' disease, not with diabetic ketoacidosis. DKA affects metabolic and acid-base balance but does not cause changes to eye appearance or positioning.

D. Decreased urinary output: In the early stages of DKA, clients usually experience increased urinary output (polyuria) due to osmotic diuresis from hyperglycemia. Decreased output may occur only in the later stages when severe dehydration and kidney compromise develop, but it is not an early expected finding.

A. Hypertension: Hyponatremia typically leads to hypotension due to fluid shifts out of the vascular space rather than hypertension, especially if it is associated with hypovolemia. Low sodium levels can reduce blood volume and pressure, making hypertension an unlikely finding in this condition.

B. Muscle cramps: Muscle cramps are a common symptom of hyponatremia due to disrupted electrolyte balance affecting neuromuscular function. Low sodium levels impair muscle contraction and nerve signal transmission, leading to cramps, weakness, and fatigue.

C. Blurred vision: Blurred vision is not a typical manifestation of hyponatremia. While severe hyponatremia can cause neurological symptoms like confusion or seizures, visual disturbances like blurred vision are not primary signs linked to sodium imbalance.

D. Constipation: Constipation is more often associated with dehydration, immobility, or other electrolyte imbalances such as hypercalcemia. Hyponatremia primarily affects neuromuscular and central nervous system function rather than gastrointestinal motility.
