The nurse is preparing to mix two medications from two different multidose vials, A and B. In which order should these actions be implemented when drawing the solutions from the vials? (Arrange from first on top to last on the bottom.)
Inject the volume of air to be aspirated from each vial.
Verify the drug and dose with the label on the vial.
Aspirate the desired volume from vial B.
Aspirate the desired volume from vial A.
The Correct Answer is B,A,D,C
A. Inject the volume of air to be aspirated from each vial: Injecting air equal to the volume to be withdrawn helps maintain pressure inside the vial and facilitates accurate aspiration of the medication.
B. Verify the drug and dose with the label on the vial: Confirming the correct medication and dose is the first step to ensure patient safety and prevent medication errors before handling any vials.
C. Aspirate the desired volume from vial B: After vial A is drawn, aspirate the second medication to complete the mixture. Drawing in this order reduces the risk of cross-contamination between vials.
D. Aspirate the desired volume from vial A: When mixing medications, draw from the vial containing the first drug (usually the one that will not interact or is to be administered first) to avoid contamination between vials.

Correct Answer is C
Explanation
A. Weight gain is not a typical adverse effect of ibuprofen; the client should be monitored for other side effects instead.
B. Regular eye exams are not required for ibuprofen therapy; this is more relevant for medications like hydroxychloroquine or corticosteroids.
C. Antacids can interfere with the absorption of ibuprofen, so it is recommended to take ibuprofen at least 2 hours before or after antacids to ensure proper effectiveness.
D. Alcohol can increase the risk of gastrointestinal bleeding with ibuprofen, so clients should be advised to avoid or limit alcohol entirely rather than consume it regularly, even in small amounts.
Correct Answer is D
Explanation
A. A headache does not indicate tolerance; tolerance refers to reduced effectiveness of the medication over time, not an adverse effect.
B. While anxiety can cause headaches, in this context, the headache is a known pharmacologic effect of nitroglycerin due to vasodilation.
C. A headache is not a sign of allergy to nitroglycerin; allergic reactions would involve symptoms like rash, swelling, or difficulty breathing.
D. Headache is a common adverse effect of nitroglycerin caused by cerebral vasodilation. It is usually mild to moderate and often decreases in frequency or intensity as the client continues therapy. Providing reassurance and education about this expected side effect is appropriate.
