A nurse is caring for a client who has increased intracranial pressure (ICP) following a closed-head injury. Which of the following actions should the nurse take?

Use log rolling to reposition the client.

Place a warming blanket on the client.

Instruct the client to cough and deep breathe.

Place the client in a supine position.

Answer and Explanation

The Correct Answer is A

Choice A Reason: This is correct because using log rolling to reposition the client helps maintain the alignment of the head and neck, which prevents further increases in ICP.

Choice B Reason: This is incorrect because placing a warming blanket on the client can cause vasodilation and increase cerebral blood ﬂow, which can raise ICP.

Choice C Reason: This is incorrect because instructing the client to cough and deep breathe can increase intrathoracic pressure and impede venous return, which can elevate ICP.

Choice D Reason: This is incorrect because placing the client in a supine position can decrease cerebral perfusion pressure and increase ICP. The client should be placed in a semi-Fowler's position with the head elevated at 30 degrees.

Correct Answer is D

Explanation

Choice A Reason: This choice is incorrect because warm, ﬂushed skin is not a sign of respiratory acidosis. Warm, ﬂushed skin may indicate fever, infection, inﬂammation, or allergic reaction, but it does not reﬂect the acid-base imbalance in the blood.

Choice B Reason: This choice is incorrect because hyperactive deep tendon reﬂexes are not a sign of respiratory acidosis. Hyperactive deep tendon reﬂexes may indicate hypocalcemia, hyperthyroidism, or spinal cord injury, but they do not reﬂect the carbon dioxide level in the blood.

Choice C Reason: This choice is incorrect because bounding peripheral pulses are not a sign of respiratory acidosis. Bounding peripheral pulses may indicate increased cardiac output, anxiety, or hyperthyroidism, but they do not reﬂect the pH level in the blood.

Choice D Reason: This choice is correct because widened QRS complexes are a sign of respiratory acidosis. QRS complexes are the segments on an electrocardiogram (ECG) that represent the depolarization of the ventricles. A normal QRS complex duration is 0.06 to 0.10 seconds, and a widened QRS complex duration is more than 0.12 seconds. A widened QRS complex may indicate hyperkalemia, which is a common complication of kidney failure and respiratory acidosis. Hyperkalemia is a condition in which the serum potassium level is higher than normal (more than 5 mEq/L). It may cause cardiac arrhythmias, muscle weakness, or paralysis.

A. Equal amount of ﬂuid drainage in each collection chamber B. Fluctuation of the ﬂuid level within the water seal chamber C. Continuous bubbling within the water seal chamber D. Absence of ﬂuid in the drainage tubing

Correct Answer is B

Explanation

Choice A Reason: Equal amount of ﬂuid drainage in each collection chamber is not a sign of proper chest tube function. The amount of ﬂuid drainage depends on the type and extent of the client's injury or surgery, and may vary from one chamber to another.

Choice B Reason:Fluctuation of the fluid level in the water seal chamber(tidaling) indicates that the chest tube is functioning properly. This fluctuation corresponds with the client's respirations and shows that air or fluid is being effectively removed from the pleural space.

Choice C Reason:Continuous bubbling within the water seal chamber: Continuous bubbling in the water seal chamber indicates an air leak, which is not normal unless the client has a pneumothorax and air is being evacuated. Otherwise, it suggests a problem with the system.

Choice D Reason: Absence of ﬂuid in the drainage tubing is not a sign of proper chest tube function. It may indicate that the chest tube is obstructed, kinked, or clamped, or that the suction is not working properly. The nurse should assess and troubleshoot the chest tube system.
