1. Which statement correctly explains the etiology of Down syndrome?

• A. There is an extra chromosome on the 21st pair.
• B. There is a missing chromosome on the 21st pair.
• C. There are two pairs of the 21st chromosome.
• D. The 21st chromosome pair is missing.

Correct answer: A

Rationale: The correct answer is A: 'There is an extra chromosome on the 21st pair.' Down syndrome is caused by the presence of an extra copy of chromosome 21, known as trisomy 21. This additional genetic material leads to the characteristics associated with Down syndrome. Choices B, C, and D are incorrect because Down syndrome is not due to a missing chromosome or having two pairs of the 21st chromosome; it results from the presence of an extra chromosome on the 21st pair.

2. Which other congenital defects are common in children with Down syndrome?

• A. Hypospadias
• B. Pyloric stenosis
• C. Heart defects
• D. Hip dysplasia

Correct answer: C

Rationale: The correct answer is C: Heart defects. Many children with Down syndrome are born with congenital heart defects. These heart abnormalities are more prevalent in individuals with Down syndrome than in the general population. Choices A, B, and D are incorrect because while they may be congenital defects in children, they are not commonly associated with Down syndrome. Hypospadias is a urogenital condition, pyloric stenosis affects the stomach, and hip dysplasia involves the hip joint, but these are not typically seen as frequently as heart defects in children with Down syndrome.

3. The nurse prepares a teaching plan for an adult client with metabolic syndrome. Which findings should the nurse address to help the client reduce the risk for diabetes mellitus and vascular disease? (Select all that apply)

• A. Abdominal obesity
• B. Blood pressure of 150/96 mmHg
• C. Increased triglyceride levels
• D. All of the above

Correct answer: D

Rationale: The correct answer is D, as all the listed factors - abdominal obesity, high blood pressure, and increased triglyceride levels - are components of metabolic syndrome. Addressing these findings is crucial to help reduce the client's risk for developing diabetes mellitus and vascular disease. Abdominal obesity is a key feature of metabolic syndrome, high blood pressure (150/96 mmHg) is a risk factor, and increased triglyceride levels are also indicative of the syndrome. Educating the client on lifestyle modifications, such as healthy eating habits, regular physical activity, and monitoring these parameters, is essential in managing metabolic syndrome and preventing associated complications. Choices A, B, and C are all correct, making choice D the correct answer.

4. What is the best position for a client experiencing a nosebleed?

• A. Sitting up and leaning forward
• B. Lying flat with a pillow under the head
• C. Sitting up and leaning back
• D. Lying on the side with the head elevated

Correct answer: A

Rationale: The best position for a client experiencing a nosebleed is sitting up and leaning forward. This position helps prevent blood from flowing down the throat and reduces the risk of aspiration. Choice B is incorrect as lying flat can lead to blood flowing down the throat. Choice C is also incorrect because leaning back may cause blood to flow backward into the throat. Choice D is incorrect as lying on the side with the head elevated is not the optimal position to manage a nosebleed effectively.

5. The cognitive impairment is classified into four levels based on the intelligence quotient (IQ). How is a child with an IQ of 45 classified?

• A. Within the normal low range
• B. Educable
• C. Trainable
• D. Severe

Correct answer: C

Rationale: A child with an IQ of 45 is classified as 'Trainable' in the context of cognitive impairment levels. This category is determined by an IQ range of 35 to 55. Choice A ('Within the normal low range') is incorrect as an IQ of 45 falls within the range associated with the 'Trainable' level, not the 'Normal low range.' Choice B ('Educable') is incorrect because this classification typically corresponds to individuals with slightly higher IQs that allow for academic progress with support. Choice D ('Severe') is incorrect as it does not align with the IQ level of 45, which falls within the 'Trainable' category.
