1. The nurse would anticipate a patient diagnosed with damage to the hypothalamus after suffering a head injury from a fall to exhibit:

ANS:   B

The hypothalamus, which is located between the cerebral hemispheres, controls body temperature. Any damage to the hypothalamus prevents the body from regulating its temperature.

2. The nurse documents vital signs on a newly admitted patient as: “blood pressure is 148/94 mm Hg, the pulse is 80 beats/min, and the respirations are 16 breaths/min.” The nurse would record the pulse pressure as:

ANS:   B

In calculating pulse pressure, take the difference between the systolic and diastolic pressures (ie, 148 – 94 = 54).

3. A patient has been admitted with hypothermia after lying unconscious overnight in an unheated apartment. The most appropriate route to assess the patient’s core temperature would be:

ANS:   D

The same blood vessels serve the hypothalamus and the tympanic membrane, so the tympanic temperature is an excellent indicator of core body temperature, although it can be affected by ear wax.

4. The nurse would document a patient as being febrile if the patient’s temperature was over:

ANS:   D

A patient with a temperature above the normal range (100.2° F) is called febrile.

5. To ensure an accurate reading when using a glass oral thermometer, it is necessary to:

ANS:   C

Oral thermometers remain at the last reading until they are shaken down; therefore, for accuracy, the thermometer must be below normal range before using.
