The client has been hospitalized after a severe head injury. The nurse recognizes that the client's difficulty in maintaining a normal body temperature when there is no infection present can be the result of which of these?
Errors by the nurse assistant in measuring temperature
Increased vasodilatation of the superficial vessels contributing to excess heat losses
The client's head injury causing interference with the function of the hypothalamus
Choosing the wrong time of day to obtain vital signs
The Correct Answer is C
A. Errors by the nurse assistant in measuring temperature. While improper technique can lead to inaccurate readings, consistent temperature fluctuations in a head injury patient are more likely due to hypothalamic dysfunction.
B. Increased vasodilatation of the superficial vessels contributing to excess heat losses. Vasodilation can play a role in heat loss, but it does not fully explain difficulty maintaining body temperature, which is primarily regulated by the hypothalamus.
C. The client's head injury causing interference with the function of the hypothalamus. The hypothalamus regulates body temperature, and a severe head injury can disrupt this function, leading to temperature instability (neurogenic fever or hypothermia) despite the absence of infection.
D. Choosing the wrong time of day to obtain vital signs. While body temperature naturally fluctuates throughout the day, major instability in temperature regulation is not due to the timing of measurement but rather an issue with the hypothalamus.

Correct Answer is D
Explanation
A. Document the findings in the patient's medical record. While documentation is important, further assessment is needed before determining if the blood pressure is abnormal for this patient.
B. Apply a cool washcloth to the patient's forehead. The patient’s temperature is normal (98.9°F), so there is no need for cooling measures.
C. Administer oxygen at 2 L/minute via nasal cannula. The pulse oximetry is 94%, which is adequate for most patients. Oxygen is not needed unless the patient shows signs of respiratory distress.
D. Ask the patient about his usual blood pressure results. The blood pressure (144/94 mmHg) is elevated, but before determining if intervention is needed, the nurse should ask if this is typical for the patient or if it is an isolated finding.
Correct Answer is C
Explanation
A. Always take the patient's blood pressure manually using a sphygmomanometer. While manual BP measurements can be more accurate, they are not the priority intervention for orthostatic hypotension, which primarily involves position changes and fall prevention.
B. Monitor the patient's neurological status carefully for symptoms of a stroke. Orthostatic hypotension can cause dizziness or fainting, but it is not a direct cause of stroke. Neurological assessment is important if symptoms arise but is not the primary intervention.
C. Assist the patient to sit and stand slowly when getting out of bed. Orthostatic hypotension causes a sudden drop in blood pressure upon standing, increasing the risk of falls and syncope. The priority action is to help the patient transition slowly from lying to sitting and standing to allow the body to adjust.
D. Check the patient's blood pressure on a lower extremity using a thigh-sized cuff. Lower extremity BP measurements are not standard for managing orthostatic hypotension. Blood pressure should be checked in both lying, sitting, and standing positions to monitor for significant drops.
