A nurse is collecting data from a client who has a calcium level of 8 mg/dL. Which of the following manifestations should the nurse expect?

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.

A. Inspiratory stridor - This is associated with upper airway obstruction and is not indicative of a pneumothorax.

B. Expiratory wheeze - Wheezing is commonly associated with lower airway conditions such as asthma or chronic obstructive pulmonary disease (COPD), not pneumothorax.

C. Coarse crackles - Coarse crackles are typically heard in conditions such as pneumonia or pulmonary edema, not pneumothorax.

D. Absence of breath sounds - This is a key manifestation of a pneumothorax. The air in the pleural space can prevent the lung from fully expanding, leading to the absence of breath sounds on the affected side.
