Sleep terrors usually occur only once a night, during stages 3 and 4 of NREM sleep. They are often accompanied by which physical sign?
- A. Intense stress.
- B. Sexual arousal.
- C. Physical strength.
- D. None of the above.
Correct Answer: D
Rationale: The correct answer is D: None of the above. Sleep terrors are not typically accompanied by intense stress, sexual arousal, or increased physical strength. Sleep terrors are characterized by sudden awakening from sleep with intense fear and a physical reaction, such as screaming or thrashing. These episodes occur during stages 3 and 4 of NREM sleep and are not associated with the physical signs mentioned in the other choices. Therefore, the correct answer is D, as sleep terrors do not necessarily involve any of the physical signs listed in the other options.

Theories based on study of the brain and its activities are called:
- A. Social
- B. Biological
- C. Psychological
- D. Psychobiological
Correct Answer: B
Rationale: The correct answer is B: Biological. Theories based on the brain and its activities fall under the field of biological psychology, which focuses on how biological factors influence behavior and mental processes. This includes studying brain structures, neural pathways, neurotransmitters, and their impact on behavior. Social (A) theories focus on interactions between individuals, Psychological (C) theories relate to mental processes and behavior, and Psychobiological (D) is a term that could be used interchangeably with Biological but is less commonly used. Hence, the most specific and appropriate term for theories related to the brain is Biological.
Which is a hallmark characteristic of bulimia nervosa?
- A. Persistent restriction of caloric intake.
- B. Binge eating followed by purging behaviors.
- C. Severe weight loss due to food refusal.
- D. Excessive exercising to burn calories.
Correct Answer: B
Rationale: The correct answer is B because bulimia nervosa is characterized by recurrent episodes of binge eating followed by compensatory behaviors such as purging. Binge eating involves consuming a large amount of food in a short period, followed by feelings of loss of control. Purging behaviors like self-induced vomiting or misuse of laxatives are used to prevent weight gain. Choices A, C, and D are incorrect because bulimia nervosa typically involves normal or fluctuating weight, not severe weight loss or excessive exercise to burn calories. Persistent restriction of caloric intake is more indicative of anorexia nervosa, not bulimia nervosa.
Of the following interventions, which one would likely be most useful when attempting to prevent or lessen the symptoms associated with sundown syndrome?
- A. Keeping the patient's room quiet and dimly lit at night
- B. Interacting frequently with the patient during evening hours
- C. Providing the patient with a large protein-based bedtime snack
- D. Giving the patient a soft stuffed animal to provide a source of security
Correct Answer: B
Rationale: The correct answer is B because interacting frequently with the patient during evening hours can help provide comfort and reassurance, reducing anxiety and agitation associated with sundown syndrome. Interacting can stimulate the patient's senses and distract from negative symptoms.
Choice A is incorrect because a quiet and dimly lit room alone may not address the underlying emotional and psychological needs of the patient during sundown syndrome.
Choice C is incorrect because a large protein-based bedtime snack may not directly impact the behavioral symptoms of sundown syndrome.
Choice D is incorrect because while a soft stuffed animal can provide some comfort, it may not address the need for human interaction and engagement during the evening hours to prevent or lessen sundown syndrome symptoms.
A 75-year-old patient comes to the clinic reporting frequent headaches. As the nurse begins the interaction, which action is most important?
- A. Complete a neurological assessment
- B. Determine whether the patient can hear as the nurse speaks
- C. Suggest that the patient lie down in a darkened room for a few minutes
- D. Administer medication to relieve the patient's pain before continuing the assessment
Correct Answer: B
Rationale: Correct Answer: B. Determine whether the patient can hear as the nurse speaks.
Rationale:
1. Hearing assessment is crucial to ensure patient understanding and communication.
2. Hearing loss may affect compliance with treatment and safety.
3. Identifying hearing deficits early can prevent misunderstandings and improve patient outcomes.
Summary:
- A: While a neurological assessment may be necessary, addressing hearing first is more immediate.
- C: Suggesting rest may help with headache management, but addressing hearing is more critical.
- D: Administering medication is premature without assessing hearing first.
A nurse has recently been assigned to a unit that specializes in the care of patients diagnosed with eating disorders. The nurse should consider which of the following actions as having priority when preparing for this new assignment?
- A. Becoming familiar with the unit's policies and procedures.
- B. Arranging to mentor with a nurse who has experience on the unit.
- C. Self-reflecting on personal feelings regarding body weight and size.
- D. Attending an educational seminar that focuses on maladaptive eating disorders.
Correct Answer: C
Rationale: The correct answer is C. Self-reflecting on personal feelings regarding body weight and size is crucial for the nurse to be aware of any biases or triggers that may affect patient care. Understanding personal attitudes towards body image can prevent unintentional harm or judgment towards patients.
A: Becoming familiar with the unit's policies and procedures is important but not the top priority when dealing with patients with eating disorders.
B: Arranging to mentor with a nurse who has experience on the unit can be helpful but does not address the nurse's personal biases.
D: Attending an educational seminar is valuable but may not address the nurse's own attitudes towards body image.
