A nurse is caring for a client with regional enteritis (Crohn's disease). Which of the following symptoms should the nurse anticipate during assessment?

The client is at risk for developing Hyponatremia due to dehydration and hypovolemia. This risk may result in Confusion.

Choice A rationale: Hypernatremia is a condition characterized by high sodium levels in the blood. It typically results from water loss exceeding sodium loss, such as in cases of inadequate water intake, excessive sweating, or osmotic diuresis. Symptoms can include thirst, irritability, confusion, and muscle twitching. However, this client's presentation of dehydration and low blood pressure is more indicative of hyponatremia rather than hypernatremia.

Choice B rationale: Hyperkalemia refers to elevated potassium levels in the blood. This condition can occur due to kidney dysfunction, excessive potassium intake, or certain medications. Symptoms of hyperkalemia include muscle weakness, fatigue, numbness, and irregular heart rhythms. While dehydration can impact electrolyte levels, the client's presentation does not specifically suggest hyperkalemia.

Choice C rationale: Hypercalcemia is a condition where calcium levels in the blood are elevated. It can result from hyperparathyroidism, certain cancers, excessive calcium or vitamin D intake, or prolonged immobilization. Symptoms include nausea, vomiting, constipation, abdominal pain, and confusion. The client's symptoms do not align with hypercalcemia, as dehydration and hypovolemia are not primary causes of elevated calcium levels.

Choice D rationale: Hyponatremia occurs when sodium levels in the blood are abnormally low. This can result from excessive fluid loss, such as through vomiting, diarrhea, sweating, or inadequate sodium intake. Symptoms include headache, nausea, vomiting, confusion, seizures, and coma. Given the client's dehydration, low blood pressure, and symptoms of weakness and dizziness, hyponatremia is the most likely risk.

Options for Response 2:

Choice A rationale: Confusion is a common symptom of hyponatremia due to the brain's response to low sodium levels, which affects neuron function and water balance within brain cells. As sodium levels fall, osmotic imbalances cause cerebral edema, leading to altered mental status, lethargy, and confusion.

Choice B rationale: Seizures can occur in severe cases of hyponatremia when the brain's neurons are significantly impacted by osmotic shifts. However, the client's symptoms do not indicate imminent seizure activity, making confusion the more appropriate choice for this scenario.

Choice C rationale: Nausea and vomiting can be symptoms of hyponatremia but are not specific enough to be the primary concern here. The client's symptoms of confusion and lethargy take precedence due to their more direct impact on overall neurological function.

Choice D rationale: Abdominal cramps can result from various electrolyte imbalances, including hyponatremia. However, this symptom is less critical compared to the neurological implications of hyponatremia, such as confusion.

Choice A rationale

Alcoholism is a common cause of hypomagnesemia due to poor dietary intake, increased renal excretion, and gastrointestinal losses. Chronic alcohol consumption leads to malnutrition and loss of magnesium through the urine, contributing to low magnesium levels.

Choice B rationale

Dehydration typically leads to hemoconcentration, which can elevate, rather than decrease, magnesium levels. Thus, it is not usually associated with low magnesium levels.

Choice C rationale

Kidney failure generally causes hypermagnesemia, not hypomagnesemia, because the kidneys cannot efficiently excrete magnesium, leading to its accumulation in the blood.

Choice D rationale

Excessive magnesium intake would result in hypermagnesemia, not hypomagnesemia, as the body accumulates more magnesium than it can excrete.
