NUR 111 Final Exam Review
The nurse is listing consequences of malignant hyperthermia. Which
consequence should be included? (Select all that apply.)
A. Renal failure
B. Disseminated intravascular coagulation
C. Pulmonary edema
D. Gastroenteritis
E. Cardiac dysrhythmias
A. Renal failure
B. Disseminated intravascular coagulation
C. Pulmonary edema
E. Cardiac dysrhythmias
Rationale: Malignant hyperthermia is an inherited disorder that affects 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.
Which type of body temperature changes in response to the environment?
A. Core
B. Metabolic
C. Physiologic
D. Surface
D. 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.
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. Evaporation
B. Conduction
C. Metabolism
D. Radiation
A. Evaporation
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.
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?
, Page 3 of 64
A. "The true temperature will not register because you are a mouth breather."
B. "Your body temperature fluctuates significantly, so a true temperature is
difficult to obtain."
C. "I will to take your temperature rectally, since it is the only reliable route in
somebody your age."
D. "Body temperature in an older adult is not a reliable indicator of the
seriousness of an illness."
D. "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.
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
temperature? (Select all that apply.)
A. Thirst
B. Cold hands
C. Shivering
D. Sleepiness
E. Sweating
B. Cold hands
C. Shivering
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.
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. Hypothermia
D. Malignant hyperthermia
A. Heat stroke
Rationale: The nurse should suspect heat stroke, which can occur during hot
weather and high humidity and results in dysfunction of the brain's thermoregulation
center. Signs and symptoms of heat-related injuries include paleness, dizziness,
nausea and vomiting, fatigue, low blood pressure, muscle cramps, and fainting. Late
signs include irritability, confusion, stupor, and coma. Hypothermia is a core body

temperature below 35°C (95°F), and is classified as mild, 32-35°C (89.6-95°F);
moderate, 28-32°C (82.4-89.6°F), or severe, below 28°C (less than 82.4°F). The
usual range of core body temperature is called normothermia. The normal range for
adults is between 36°C and 38.5°C (96.8°F and 101.3°F). Malignant hyperthermia is
a potentially fatal, inherited disorder that results from the body's reaction to volatile
inhalation of anesthetic gases and succinylcholine, a depolarizing neuromuscular
blocker.
The nurse is preparing to use the tympanic membrane to measure the
temperature of a 4-year-old child. Which approach should the nurse take when
completing this measurement?
A. Pull the earlobe back and down.
B. Pull the pinna back and down.
C. Pull the earlobe back and up.
D. Pull the pinna back and up.
D. Pull the pinna back and up.
Rationale: The pinna is pulled straight back and upward when taking temperature in
children over 3 years of age. To measure temperature using the tympanic membrane
in an infant, the pinna is pulled straight back and slightly downward. The earlobe is
not manipulated to measure temperature using the tympanic membrane.
Which is a noninvasive method that the nurse uses to assess a client's
temperature? (Select all that apply.)
A. Oral
B. Tympanic membrane
C. Rectal
D. Axillary
E. Temporal artery
D. Axillary
E. Temporal artery
Rationale: The two methods of measuring temperature that are safe and noninvasive
are the axillary method and temporal artery. The client could bite down during the
oral approach and damage sensitive oral mucosa. The rectal method is invasive and
could damage sensitive tissue. Although generally safe, the tympanic temperature
measurement is an invasive procedure.
The nurse is planning to assess a 4-year-old child to help determine the cause
of the child's fever. Which body system is a priority to assess? (Select all that
apply.)
A. Neurologic
B. Respiratory
C. Urinary
D. Musculoskeletal
E. Gastrointestinal
B. Respiratory
C. Urinary
E. Gastrointestinal
