Correct Answer: D

Rationale: Encouraging the client to continue taking the medication is crucial in the management of multiple sclerosis. Beta-1 interferon is a disease-modifying drug used to reduce the frequency and severity of relapses in multiple sclerosis. Discontinuing the medication without medical advice can lead to disease exacerbation. It is essential for the client to maintain regular dosing to achieve optimal therapeutic effects and disease control.

Correct Answer: B

Rationale: Insulin glargine is a long-acting insulin that should not be mixed with other insulins in the same syringe. Mixing it with other insulins can alter its pharmacokinetics and effectiveness. Insulin glargine is usually administered at the same time each day, often at bedtime, to provide a consistent basal level of insulin over 24 hours.

Correct Answer: B

Rationale: In this scenario, the nurse should contact the pharmacy to obtain the correct heparin formulation as the prescription calls for heparin 1,000 units IV STAT. Low molecular weight heparin is not the same as unfractionated heparin, and therefore, the nurse should not administer the available low molecular weight heparin without first obtaining the correct medication. Diluting the available heparin, calculating an equivalent dose, or changing the route of administration would not address the discrepancy between the prescribed heparin and the available low molecular weight heparin.

Correct Answer: C

Rationale: The nurse should monitor the partial thromboplastin time to evaluate the efficacy of heparin. Partial thromboplastin time reflects the anticoagulant effect of heparin by measuring the intrinsic pathway of coagulation. Platelet count assesses platelet levels and is not specific to heparin efficacy. Prothrombin time is used to monitor warfarin therapy. Serum levels of protamine sulfate are not used to evaluate the efficacy of heparin.
