The early stage of Alzheimer's disease is characterized by:
- A. Loss of recent memory
- B. Loss of remote memory
- C. Withdrawal from family
- D. Apraxia
Correct Answer: A
Rationale: The correct answer is A: Loss of recent memory. In the early stage of Alzheimer's disease, individuals typically experience difficulty remembering recent events, conversations, or information. This is due to the initial impact of the disease on the hippocampus and other brain regions responsible for forming new memories. Choices B, C, and D are incorrect because loss of remote memory (choice B) usually occurs in later stages, withdrawal from family (choice C) can be a result of various factors beyond memory loss, and apraxia (choice D) refers to the inability to perform coordinated movements and is not a primary symptom of early-stage Alzheimer's.

A patient with anorexia nervosa is resistant to weight gain. What is the rationale for establishing a contract with the patient to participate in measures to produce a specified weekly weight gain?
- A. Severe anxiety concerning eating is expected, so objective and subjective data are needed.
- B. Patient involvement in decision-making increases sense of control and promotes collaboration.
- C. The patient's family is not supportive of the treatment plan.
- D. None of the above.
Correct Answer: B
Rationale: Correct Answer: B - Patient involvement in decision-making increases sense of control and promotes collaboration.
Rationale:
1. Involving the patient in decision-making empowers them and increases their sense of control over their treatment.
2. Collaborating with the patient fosters a positive therapeutic relationship.
3. This approach is more likely to lead to better treatment adherence and outcomes.
Summary:
A: While objective and subjective data are important, this choice does not address the need for patient involvement in decision-making and collaboration.
C: The lack of family support is not directly related to the rationale for establishing a contract with the patient.
D: This choice is incorrect as patient involvement is crucial in promoting successful treatment outcomes.
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.
A patient who takes lithium phones the nurse at the clinic to say, "I've had diarrhea for 4 days. I feel weak and unsteady when I walk. My usual hand tremor has gotten worse. What should I do?" Which instruction by the nurse is appropriate?
- A. Have someone bring you to the clinic immediately.
- B. Restrict food and fluids for 24 hours and stay in bed.
- C. Drink a large glass of water with 1 teaspoon of salt added.
- D. Take antidiarrheal medication hourly until the diarrhea subsides.
Correct Answer: A
Rationale: The correct answer is A: Have someone bring you to the clinic immediately. The patient is experiencing symptoms of lithium toxicity, including diarrhea, weakness, unsteadiness, and worsening hand tremor. These symptoms indicate a potential lithium overdose, which can be life-threatening. Bringing the patient to the clinic immediately is crucial for assessment, monitoring, and intervention.
Choice B is incorrect because restricting food and fluids can worsen dehydration and electrolyte imbalances. Choice C is incorrect as adding salt to water can exacerbate electrolyte abnormalities in lithium toxicity. Choice D is incorrect as taking antidiarrheal medication can further worsen the symptoms and delay appropriate medical treatment.
A nurse is planning care for a patient with bulimia nervosa. Which goal should be included in the care plan?
- A. The patient will engage in daily exercise to prevent weight gain.
- B. The patient will maintain a healthy, balanced diet without purging behaviors.
- C. The patient will gain 1-2 pounds per week.
- D. The patient will eliminate binge eating and purging behaviors entirely.
Correct Answer: B
Rationale: Step-by-step rationale:
1. Maintaining a healthy, balanced diet without purging behaviors is crucial for managing bulimia nervosa.
2. This goal promotes physical health and addresses the underlying disordered eating habits.
3. It focuses on establishing sustainable eating patterns to support overall well-being.
4. It helps prevent complications associated with bulimia, such as electrolyte imbalances.
Summary:
- Option A is incorrect as excessive exercise can be a compensatory behavior in eating disorders.
- Option C is incorrect as rapid weight gain is not recommended in the treatment of bulimia.
- Option D is incorrect as complete elimination of binge eating and purging may be unrealistic initially.
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.
