A nurse is preparing to mix NPH insulin and regular insulin for administration.
Which of the following actions should the nurse take?
Use a tuberculin syringe.
Inject air into each vial.
Withdraw the NPH insulin first.
Shake the regular insulin vial.
The Correct Answer is B
Choice A rationale:
While a tuberculin syringe can be used for insulin administration, it’s not necessary when mixing NPH and regular insulin. Insulin syringes are typically used for this purpose.
Choice B rationale:
Injecting air into each vial before withdrawing insulin helps equalize pressure and makes it easier to draw up the insulin. This should be done before withdrawing any insulin.
Choice C rationale:
Withdrawing NPH insulin first contradicts the standard practice of drawing up insulins. The usual recommendation is to draw up short-acting (regular) insulin before intermediate-acting (NPH) insulin.
Choice D rationale:
Shaking the regular insulin vial is unnecessary and could potentially create bubbles, making it harder to draw up the correct dose of insulin.

Correct Answer is B
Explanation
Choice A rationale:
Hypernatremia (high sodium levels) is not a common side effect of spironolactone. Spironolactone is a potassium-sparing diuretic and does not typically affect sodium levels.
Choice B rationale:
Hyperkalemia (high potassium levels) is a potential adverse effect of spironolactone. As a potassium-sparing diuretic, spironolactone can cause an increase in serum potassium levels.
Choice C rationale:
Hypophosphatemia (low phosphate levels) is not typically associated with spironolactone use.
Choice D rationale:
Hypocalcemia (low calcium levels) is also not a common side effect of spironolactone.
Correct Answer is D
Explanation
Choice A rationale:
Fluoxetine is an antidepressant. While some antidepressants are used for chronic pain management, fluoxetine is not typically used for this purpose.
Choice B rationale:
Methylphenidate is a stimulant used to treat attention deficit hyperactivity disorder (ADHD) and is not used for pain management.
Choice C rationale:
Lorazepam is a benzodiazepine used for treating anxiety, seizures, and insomnia. It is not typically used for managing neuralgia pain.
Choice D rationale:
Carbamazepine is an anticonvulsant that is commonly used to manage trigeminal neuralgia. It helps to reduce nerve impulses that cause pain.
