,NU 160/NU160 Exam 4 | Mental Health Concepts
(2026) Q&A | Galen College
1. A patient with bulimia nervosa is most likely to exhibit which physical
finding?
A) BMI below 17 and lanugo
B) Amenorrhea and bradycardia
C) Dental erosion and parotid gland enlargement
D) Excessive weight loss and muscle wasting
Correct Answer: Dental erosion and parotid gland enlargement
Rationale: Bulimia nervosa involves repeated self-induced vomiting, which
exposes teeth to gastric acid causing enamel erosion. The parotid glands may
become enlarged from frequent stimulation. Low BMI, lanugo, and amenorrhea
are more characteristic of anorexia nervosa.
2. The nurse is caring for a patient with anorexia nervosa. Which behavior is
characteristic of this disorder?
A) Intense fear of gaining weight and significantly low body weight
B) Binge eating followed by self-induced vomiting
C) Normal body weight with feelings of guilt after eating
D) Eating large amounts of food without compensatory behaviors
Correct Answer: Intense fear of gaining weight and significantly low body
weight
,Rationale: Anorexia nervosa is defined by restriction of energy intake leading to
significantly low body weight, an intense fear of gaining weight, and disturbance
in self-perceived weight or shape. Bingeing and purging are typical of bulimia.
3. Which sleep disorder is classified as a dyssomnia?
A) Sleepwalking
B) Nightmare disorder
C) Sleep terrors
D) Narcolepsy
Correct Answer: Narcolepsy
Rationale: Dyssomnias are disorders of sleep quantity or timing, including
insomnia, hypersomnolence, narcolepsy, and sleep apnea. Parasomnias involve
abnormal behaviors during sleep, such as sleepwalking, night terrors, and
nightmares.
4. A patient reports an almost irresistible urge to move the legs, especially when
resting in the evening, accompanied by creeping and tingling sensations. The
nurse suspects:
A) Insomnia
B) Restless leg syndrome
C) Narcolepsy
D) Obstructive sleep apnea
Correct Answer: Restless leg syndrome
, Rationale: Restless leg syndrome is a sensorimotor disorder characterized by an
urge to move the legs, often with uncomfortable sensations, that worsens at
rest and improves with movement. It is not primarily a sleep disorder but often
disrupts sleep.
5. A patient with binge-eating disorder is most likely to exhibit which behavior?
A) Self-induced vomiting after each meal
B) Daily use of laxatives and diuretics
C) Eating large amounts of food rapidly, feeling uncomfortably full, without
purging
D) Strict calorie counting and excessive exercise
Correct Answer: Eating large amounts of food rapidly, feeling uncomfortably
full, without purging
Rationale: Binge-eating disorder involves recurrent episodes of binge eating
without the regular use of compensatory behaviors (purging, fasting, excessive
exercise). Distress and guilt are common. Purging is typical of bulimia.
6. Which medication is FDA-approved for the treatment of bulimia nervosa?
A) Lithium
B) Risperidone
C) Lorazepam
D) Fluoxetine
Correct Answer: Fluoxetine
