1. Wernicke-Korsakoff syndrome is associated with which vitamin deficiency?

A. Thiamine (B1)
B. Riboflavin (B2)
C. Niacin (B3)
D. Pyridoxine (B6)

Correct answer: A

Rationale: Wernicke-Korsakoff syndrome is indeed associated with thiamine (vitamin B1) deficiency. This syndrome is commonly seen in individuals with chronic alcoholism due to poor diet and impaired thiamine absorption. Thiamine is essential for normal brain function and energy metabolism. Riboflavin (B2) deficiency can lead to symptoms like sore throat and swollen mucous membranes, not Wernicke-Korsakoff syndrome. Niacin (B3) deficiency causes pellagra, characterized by dermatitis, diarrhea, dementia, and death, but not Wernicke-Korsakoff syndrome. Pyridoxine (B6) deficiency can result in dermatitis, glossitis, and peripheral neuropathy, but it is not associated with Wernicke-Korsakoff syndrome.

2. The recommended daily fluid intake of patients maintained using hemodialysis is:

A. 150 mL plus the volume of urinary output
B. 500 mL plus the volume of urinary output
C. 1000 mL plus the volume of urinary output
D. 1500 mL plus the volume of urinary output

Correct answer: C

Rationale: The correct answer is C: 1000 mL plus the volume of urinary output. Fluid intake is typically restricted in hemodialysis patients to prevent fluid overload. The recommended daily fluid intake for these patients is 1000 mL plus any urinary output. Choice A (150 mL plus the volume of urinary output) is too low and would not provide enough fluid for these patients. Choice B (500 mL plus the volume of urinary output) is also insufficient. Choice D (1500 mL plus the volume of urinary output) is too high and may lead to fluid overload in hemodialysis patients.

3. As a nurse assigned for care for geriatric patients, you need to frequently assess your patient using the nursing process. Which of the following needs be considered with the highest priority?

A. Patients own feeling about his illness
B. Safety of the client especially those elderly clients who frequently falls
C. Nutritional status of the elderly client
D. Physiologic needs that are life threatening

Correct answer: C

Rationale: Effective nursing care involves comprehensive assessments that address all aspects of a patient's condition, ensuring that interventions are appropriately targeted and outcomes are optimized.

4. Which of the following methods is the best method for determining nasogastric tube placement in the stomach?

A. X-ray
B. Observation of gastric aspirate
C. Testing of pH of gastric aspirate
D. Placement of external end of tube under water

Correct answer: A

Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.
