What is the priority intervention for a patient experiencing an acute asthma attack?

Correct Answer: A

Rationale: Administering a bronchodilator is the priority intervention in an acute asthma attack. Bronchodilators help to quickly open the airways, relieve bronchospasm, and improve breathing. Encouraging the patient to drink fluids may be beneficial for other conditions but is not the priority in an acute asthma attack. Applying a high-flow oxygen mask may be necessary in severe cases of respiratory distress but is not the initial priority when managing an acute asthma attack. Performing chest physiotherapy is not indicated as the primary intervention for an acute asthma attack and may not address the immediate need to open the airways and improve breathing.

Correct Answer: C

Rationale: The correct answer is C. Trimming toenails straight across and filing the edges is crucial in diabetic foot care to prevent ingrown toenails and foot injuries. Soaking feet daily can lead to dryness and skin breakdown, increasing the risk of infection. Selecting well-fitting shoes is important to prevent pressure points and skin damage, not tight-fitting shoes. Using heating pads can result in burns or injuries due to decreased sensation in diabetic feet, so it's essential to avoid them.

Correct Answer: A

Rationale: Abdominal distension in a patient receiving enteral tube feeding may indicate a complication such as intolerance to feeding, delayed gastric emptying, or obstruction. Abdominal distension is a common sign of gastrointestinal issues related to enteral tube feeding. Weight gain is typically an expected outcome if the patient is receiving adequate nutrition. Decreased bowel sounds may indicate decreased motility but are not specific to enteral tube feeding complications. Diarrhea can occur due to various reasons, including infections, medications, or dietary changes, but it is not the most likely indication of a complication in enteral tube feeding.

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.

Correct Answer: A

Rationale: The correct answer is A: Insulin deficiency. Diabetic ketoacidosis occurs due to a severe lack of insulin, causing the body to break down fat for energy, leading to the production of ketones and acidification of the blood. Option B, Overhydration, is incorrect as DKA is characterized by dehydration rather than overhydration. Option C, Excess carbohydrate intake, is incorrect because while high blood sugar levels can contribute to DKA, the primary cause is insulin deficiency. Option D, Excess insulin, is also incorrect as DKA is not caused by an excess of insulin but rather by a lack of it.
