A nurse is reinforcing teaching with a client who asks which diagnostic test is the preferred method for detecting cervical cancer. Which is an appropriate response by the nurse?

a. Decreased calcium level: NG tube drainage is more likely to result in hypokalemia (decreased potassium) than hypocalcemia (decreased calcium).

b. Decreased potassium level: NG tube drainage, which contains stomach contents, can lead to loss of potassium. Monitoring for hypokalemia is crucial as it can result in cardiac dysrhythmias.

c. Elevated magnesium level: NG tube drainage is not typically associated with an increase in magnesium levels.

d. Elevated sodium level: NG tube drainage may contribute to sodium loss, leading to hyponatremia, rather than hypernatremia.

a. Battle's sign: Battle's sign is bruising over the mastoid process and is not a direct manifestation of increased intracranial pressure.

b. Nuchal rigidity: Nuchal rigidity (stiff neck) is associated with irritation of the meninges and is not a specific sign of increased intracranial pressure.

c. Lethargy: Lethargy or altered level of consciousness is a common manifestation of increased intracranial pressure. It can range from mild drowsiness to severe impairment of consciousness.

d. Polyuria: Polyuria is not a typical manifestation of increased intracranial pressure. Increased urine output may be associated with other conditions, such as diabetes or diuretic use.
