It is a secondary dementia indicated by loss of recent memory and disorientation to time and place.
- A. Alzheimer's disease.
- B. Vascular dementia.
- C. Lewy body dementia.
- D. None of the above.
Correct Answer: A
Rationale: The correct answer is A: Alzheimer's disease. Alzheimer's disease is a common type of dementia characterized by progressive cognitive decline, including loss of recent memory and disorientation to time and place. This is due to the accumulation of amyloid plaques and neurofibrillary tangles in the brain. Vascular dementia (B) is caused by reduced blood flow to the brain, leading to cognitive impairment. Lewy body dementia (C) is characterized by the presence of abnormal protein deposits called Lewy bodies in the brain. Choosing D (None of the above) would be incorrect as Alzheimer's disease specifically matches the description provided in the question.

A patient has a maladaptive response to eating regulation. Findings include the following: height, 5 feet 3 inches; current weight, 80 pounds with weight loss of 30% of body weight over the past 3 months; T, 96.6m F; BP, 68/40; P, 40; R, 20; poor skin turgor; lanugo; amenorrhea of 6 months' duration; admits to restricting intake to 350 calories daily; is a vegetarian; dissatisfied with eating pattern as evidenced by patient statement, 'I need to lose another 10 pounds to be at ideal weight'; diagnostic testing reveals serum potassium of 2.9 mEq/L and urine specific gravity of 1.028. Which of the following would be the highest priority nursing diagnosis for this patient?
- A. Imbalanced nutrition, less than body requirements.
- B. Disturbed body image.
- C. Deficient fluid volume.
- D. Powerlessness.
Correct Answer: C
Rationale: The correct answer is C: Deficient fluid volume. The patient is displaying signs of severe malnutrition and dehydration, as evidenced by significant weight loss, low blood pressure, low heart rate, and poor skin turgor. The low serum potassium and high urine specific gravity indicate dehydration. Addressing fluid volume deficiency is the top priority to stabilize the patient's condition and prevent further complications like electrolyte imbalances and organ damage. Choices A and B are important but secondary to addressing the immediate threat of dehydration. Choice D is not the priority as the patient's primary concern is physiological rather than psychological.
