1. Which disorder is characterized by demyelination of neurons in the central nervous system?

• A. Multiple sclerosis
• B. Parkinson's disease
• C. Alzheimer's disease
• D. Huntington's disease

Correct answer: A

Rationale: Multiple sclerosis is the correct answer. It is an autoimmune disease that specifically targets and damages the myelin sheath surrounding neurons in the central nervous system. This demyelination disrupts the transmission of nerve signals and leads to a variety of neurological symptoms. Parkinson's disease (Choice B), Alzheimer's disease (Choice C), and Huntington's disease (Choice D) are neurodegenerative disorders that do not primarily involve demyelination of neurons in the CNS. Parkinson's disease is characterized by the loss of dopamine-producing neurons, Alzheimer's disease by the formation of plaques and tangles in the brain, and Huntington's disease by a genetic mutation affecting nerve cells.

2. Which of the following is a primary intervention for a patient experiencing hypoglycemia?

• A. Administering insulin
• B. Providing a complex carbohydrate meal
• C. Giving 15 grams of a fast-acting carbohydrate, like glucose tablets
• D. Encouraging the patient to exercise

Correct answer: C

Rationale: Giving 15 grams of a fast-acting carbohydrate, such as glucose tablets, is the primary intervention for hypoglycemia. This rapid-acting carbohydrate helps quickly raise blood sugar levels, providing immediate relief to the patient. Administering insulin (Choice A) would further lower blood sugar levels, exacerbating the hypoglycemia. Providing a complex carbohydrate meal (Choice B) would not act quickly enough to address the immediate low blood sugar issue. Encouraging the patient to exercise (Choice D) is inappropriate during hypoglycemia as it can further deplete glucose levels.

3. A new mother who is breastfeeding her newborn for the first time after delivery reports nipple pain when the baby sucks. Based on this client problem, which action should the PN take?

• A. Ensure that all the areolar tissue of the nipple is in the infant's mouth
• B. Have the mother reposition the infant from the cradle to the football hold
• C. Check for engorgement and assess the nipples for cracks or lesions
• D. Apply a warm compress to the breast for 10 minutes before each feeding

Correct answer: A

Rationale: Proper latch, including all the areolar tissue in the infant's mouth, is essential to prevent nipple pain and ensure effective breastfeeding. Option A is correct because ensuring that all the areolar tissue of the nipple is in the infant's mouth helps achieve a good latch, reducing nipple pain. Option B is incorrect as repositioning the infant may not address the root cause of the pain related to latch issues. Option C is incorrect because while checking for engorgement and nipple issues is important, it does not directly address the latch concern causing the pain. Option D is incorrect as applying a warm compress is not recommended for breastfeeding mothers; a warm compress can help with pain associated with engorgement, but it does not address latch issues.

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

• A. Hyponatremia
• B. Hypercalcemia
• C. Hyperkalemia
• D. Hypokalemia

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.

5. A client who had a thyroidectomy 24 hours ago reports tingling around the mouth and in the fingertips. What should the nurse do first?

• A. Check the client’s calcium levels.
• B. Administer a dose of calcium gluconate.
• C. Assess the client's incision site for bleeding.
• D. Notify the healthcare provider.

Correct answer: A

Rationale: Tingling around the mouth and in the fingertips can indicate hypocalcemia, a potential complication after thyroidectomy due to accidental damage to the parathyroid glands. Checking calcium levels is crucial as it helps in diagnosing hypocalcemia accurately. Administering calcium without knowing the actual calcium levels can be dangerous. Assessing the incision site for bleeding is important but not the priority in this situation. Notifying the healthcare provider can be done after assessing and managing the immediate concern of hypocalcemia.
