What measure protects the nurse when preparing cytotoxic drugs?
Wearing protective equipment such as gloves, mask, and gown
Washing hands before preparation
Mixing medication in a 1-L bag
Administering medication IM
The Correct Answer is A
A. Wearing protective equipment such as gloves, mask, and gown is essential when preparing cytotoxic drugs to protect the nurse from potential exposure to harmful substances.
B. While washing hands is important for general hygiene, it does not specifically protect against cytotoxic drug exposure.
C. Mixing medication in a 1-L bag does not offer specific protection to the nurse and is not a standard measure for safety.
D. Administering medication intramuscularly (IM) is a route of administration and does not relate to protection measures while preparing cytotoxic drugs.

Correct Answer is C
Explanation
A. Short-acting insulin does not cover basal needs; that is the role of long-acting insulin.
B. Intermediate-acting insulin does not primarily cover mealtime glucose spikes; it provides a more prolonged effect.
C. Short-acting insulin is used to manage blood glucose during meals, while intermediate-acting insulin helps maintain glucose control between meals and overnight, making this the correct choice.
D. Short-acting and intermediate-acting insulins have different onset and peak times; they do not share the same pharmacokinetic properties.
Correct Answer is B
Explanation
A. A drug that binds tightly to protein is typically released slowly, not quickly, as it remains bound in circulation.
B. Tight binding to proteins usually results in a prolonged duration of action since the drug is released gradually into the bloodstream, leading to sustained therapeutic effects.
C. Drugs that bind tightly to protein are generally not excreted quickly; they remain in circulation longer due to the binding.
D. While toxicity can occur with any drug, tight protein binding does not inherently lead to toxicity; it primarily affects the pharmacokinetics of the drug.
