1. What is the most common genetic cause of intellectual disability?

• A. Down syndrome
• B. Fragile X syndrome
• C. Prader-Willi syndrome
• D. Turner syndrome

Correct answer: B

Rationale: The correct answer is Fragile X syndrome because it is the most common inherited cause of intellectual disability, resulting from a mutation in the FMR1 gene. Down syndrome, Prader-Willi syndrome, and Turner syndrome are not the most common genetic causes of intellectual disability. Down syndrome is caused by the presence of an extra chromosome 21, Prader-Willi syndrome results from specific genetic abnormalities on chromosome 15, and Turner syndrome is characterized by the absence of part or all of one of the X chromosomes.

2. What is the first action a healthcare professional should take when a patient’s nasogastric (NG) tube becomes clogged?

• A. Flush the tube with water
• B. Reposition the patient
• C. Attempt to aspirate the clog with a syringe
• D. Administer a medication to dissolve the clog

Correct answer: C

Rationale: When a patient's nasogastric (NG) tube becomes clogged, the first action to take is to attempt to aspirate the clog with a syringe. This is a standard and initial step to clear the blockage in the tube. Flushing the tube with water (Choice A) may not address the specific clog; repositioning the patient (Choice B) is not directly related to clearing the tube. Administering a medication to dissolve the clog (Choice D) should only be considered after simpler methods like aspiration have been attempted.

3. Which vitamin deficiency is most associated with night blindness?

• A. Vitamin A
• B. Vitamin B12
• C. Vitamin C
• D. Vitamin D

Correct answer: A

Rationale: The correct answer is Vitamin A. Vitamin A deficiency leads to night blindness because this vitamin is crucial for the formation of rhodopsin, a photopigment in the retina. Rhodopsin is essential for vision in low-light conditions. Vitamin B12 deficiency can lead to anemia and neurological issues but is not directly related to night blindness. Vitamin C deficiency can cause scurvy, affecting connective tissues, but not night vision. Vitamin D deficiency can lead to bone disorders but is not primarily associated with night blindness.

4. When caring for a patient with a chest tube, which nursing action is most important?

• A. Clamping the chest tube every 2 hours to prevent air leaks
• B. Keeping the drainage system below chest level
• C. Emptying the drainage system every hour to prevent backflow
• D. Removing the chest tube when drainage decreases significantly

Correct answer: B

Rationale: The most crucial nursing action when caring for a patient with a chest tube is to keep the drainage system below chest level (choice B). This position helps ensure proper drainage and prevents backflow of fluid or air into the pleural space, promoting optimal functioning of the chest tube. Clamping the chest tube every 2 hours (choice A) is incorrect as it can obstruct the drainage system and lead to complications. Emptying the drainage system every hour (choice C) is unnecessary unless there are specific clinical indications. Removing the chest tube when drainage decreases significantly (choice D) is also incorrect as the decision should be based on overall clinical assessment rather than drainage amount alone.

5. A Native American client is admitted with a diagnosis of psychosis not otherwise specified. The client's family seems to regard the client's hallucinations as normal. What assessment can be made?

• A. The client's family regards the hallucinations from a cultural context
• B. The client will benefit from a talking circle
• C. The client will need a medicine man
• D. The client will need a single room

Correct answer: A

Rationale: Choice A is correct because the family may interpret the client's hallucinations through their cultural lens, potentially viewing them as normal or spiritually significant. Understanding and acknowledging the cultural context is essential for providing culturally sensitive care. Choices B, C, and D are incorrect because while talking circles and seeking guidance from a medicine man may be culturally relevant interventions in some contexts, the priority in this situation is to recognize and respect the family's perspective on the client's hallucinations.
