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

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. Which type of isolation precaution is required for a patient with tuberculosis (TB)?

Correct answer: C

Rationale: The correct answer is C: Airborne precautions. Tuberculosis (TB) is transmitted via airborne particles, thus requiring airborne precautions to prevent the spread of infection. This includes using an N95 respirator to filter out small infectious particles. Droplet precautions (Choice A) are used for diseases that spread through large respiratory droplets. Contact precautions (Choice B) are for direct or indirect contact with the patient or their environment. Standard precautions (Choice D) are used for all patients to prevent the spread of infection through blood, bodily fluids, non-intact skin, and mucous membranes.

3. Which electrolyte imbalance is most commonly associated with seizures?

Correct answer: A

Rationale: The correct answer is A: Hyponatremia. Hyponatremia, characterized by low sodium levels in the blood, can lead to cerebral edema and seizures due to water shifting into brain cells. Hypercalcemia (choice B) does not commonly cause seizures but can result in muscle weakness and cardiac arrhythmias. Hyperkalemia (choice C) may lead to muscle weakness and cardiac arrhythmias, but it is less frequently associated with seizures. Hypokalemia (choice D) is linked to muscle weakness and cardiac arrhythmias but is not typically related to seizures.

4. When documenting information in a client's medical record, what should the nurse do?

Correct answer: D

Rationale: When documenting information in a client's medical record, the nurse should end each entry with their signature and title. This practice is crucial for legal and professional standards compliance as it ensures that the documentation is attributable to the responsible individual. Choices A, B, and C are incorrect because while crossing out errors, using a black ink pen, and leaving a blank line before each entry are good practices, they are not as critical as ensuring each entry is signed and titled by the nurse for accountability and traceability.

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

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.
