And Correct Answers A+
1. The nurse is listing consequences of malignant hyperthermia. Which conse-
quence should be included? (Select all that apply.)
A. Gastroenteritis
B.Pulmonary edema
C.Renal failure
D.Disseminated intravascular coagulation
E.Cardiac dysrhythmias: BCDE
Rationale: Malignant hyperthermia is an inherited disorder that attects temperature regulation. With this condition,
an individual experiences a serious reaction to inhaled anesthetic gases and depolarizing neuromuscular blockers.
If not treated, the individual will develop renal failure, pulmonary edema, cardiac dysrhythmias, and disseminated
intravascular coagulation. Malignant hypothermia does not cause gastroenteritis.
2. Which type of body temperature changes in response to the environment?
A.Core
B.Metabolic
C.Surface
D.Physiologic: C.Surface
Rationale: Surface temperature changes in response to the environment. Core temperature remains constant and stays
within a specific range. Metabolic and physiologic are not types of body temperature.
3. The nurse observes a mother stroking her child's arms and legs with a cool,
damp washcloth. Which method of heat transfer is the mother using to reduce
the fever?
A. Radiation
B.Conduction
C.Metabolism
D.Evaporation: D.Evaporatin
Rationale: Heat can be transferred between places or objects. Evaporation is the conversion of water to vapor, which is
what occurs when the mother applies cool water to the child's limbs. Radiation is the release of heat through no physical
contact. Conduction is the release of heat through physical contact. Metabolism is not a method of heat transfer.
,4. An older adult client asks the nurse, "Why is my body temperature only 99°F
if I have this serious infection?" Which is the nurse's best response?
A. "I will to take your temperature rectally, since it is the only reliable route in
, somebody your age."
B. "The true temperature will not register because you are a mouth breather."
C. "Body temperature in an older adult is not a reliable indicator of the serious-
ness of an illness."
D. "Your body temperature fluctuates significantly, so a true temperature is
difficult to obtain.": C."Body temperature in an older adult is not a reliable indicator of the seriousness of
an illness."
Rationale: Body temperature may not be a valid indication of serious illness in an older adult. The older adult may
have an infection and exhibit only a slight temperature elevation. Other symptoms, such as confusion and restlessness,
may be present. These require follow-up to determine whether an underlying disease process is present. There is no
evidence to support that the client is a mouth breather. Rectal temperatures in older adult clients may be contraindicated
if hemorrhoids are present. Body temperature in an older adult does not fluctuate significantly.
5. The nurse is assessing a client who fell into a cold lake. Which assessment
finding indicates that the client's body is attempting to regulate its tempera-
ture? (Select all that apply.)
A.Shivering
B.Cold hands
C.Sleepiness
D.Sweating
E.Thirst: AB
Rationale: When the skin is chilled, the body attempts to regulate temperature by vasoconstriction of blood vessels. This
could be why the client's hands are cold. The body also shivers to increase heat production. The body does not regulate
temperature through sleep, thirst, or by sweating.
6. On a hot, humid day, a client presents with a body temperature of 40.9°C
(105.6°F), dry and flush skin, vomiting, low blood pressure, and muscle cramps.
Which type of injury should the nurse suspect based on the manifestations?
A.Heat stroke
B.Normothermia
C.Malignant hyperthermia
D.Hypothermia: A.Heat stroke
Rationale: The nurse should suspect heat stroke, which can occur during hot weather and high humidity and results
