A nurse is educating a group of pregnant women about neural tube defects.
Which of the following conditions should the nurse mention as an example of a neural tube defect?
Spina bifida.
Cerebral palsy.
Muscular dystrophy.
Hydrocephalus.
The Correct Answer is A
Choice A rationale
Spina bifida is indeed an example of a neural tube defect. It occurs when the neural tube doesn’t close completely somewhere along the spine during fetal development. This is the correct answer.
Choice B rationale
Cerebral palsy is not a neural tube defect. It is a group of disorders that affect a person’s ability to move and maintain balance and posture.
Choice C rationale
Muscular dystrophy is not a neural tube defect. It is a group of diseases that cause progressive weakness and loss of muscle mass.
Choice D rationale
Hydrocephalus is not a neural tube defect. It is a condition in which an accumulation of cerebrospinal fluid (CSF) occurs within the brain.

Correct Answer is C
Explanation
Choice A rationale
The client who has an indwelling urinary catheter to gravity drainage is not at risk for hypokalemia. The kidneys regulate the balance of potassium by removing excess potassium into the urine. The use of a urinary catheter would not affect this process.
Choice B rationale
The client who has a chest tube to water seal is not at risk for hypokalemia. Chest tubes are used to treat conditions that can cause the lung to collapse, such as pneumothorax, hemothorax, or pleural effusion. They do not affect the body’s potassium levels.
Choice C rationale
The client who has a nasogastric (NG) tube to suction is at risk for hypokalemia. Hypokalemia, or low potassium levels, can occur with loss of gastric fluids because these fluids contain potassium. With an NG tube to suction, these fluids are being removed from the body, which can lead to a decrease in potassium levels.
Choice D rationale
The client who has a tracheostomy tube attached to humidified oxygen is not at risk for hypokalemia. A tracheostomy tube allows air to enter the lungs. It does not affect the body’s potassium levels.
Correct Answer is A
Explanation
Choice A rationale
Glipizide is a sulfonylurea medication used in Type 2 Diabetes to sensitize pancreatic beta cells and stimulate insulin release. It helps control blood sugar levels by prompting your pancreas to produce insulin. This medication is effective only in people whose bodies produce insulin naturally.
Choice B rationale
Glipizide does not replace insulin that is not being produced by your pancreas. Instead, it stimulates the pancreas to release insulin.
Choice C rationale
Glipizide does not absorb excess carbohydrates in your system. Its primary action is to stimulate the release of insulin from the pancreas.
Choice D rationale
Glipizide does not prevent your liver from destroying your insulin. Its main function is to stimulate the pancreas to release insulin, which helps control blood sugar levels.
