Correct Answer: C

Rationale: The correct statement for the nurse to include when teaching a client about digoxin is to 'Take your pulse before taking this medication.' This is essential because clients taking digoxin need to monitor their pulse to detect signs of bradycardia, a common adverse effect of the medication. Option A is incorrect because digoxin is usually recommended to be taken with food to avoid gastrointestinal upset. Option B is incorrect because antacids can interfere with the absorption of digoxin. Option D is incorrect because contacting the provider for visual changes is important, but monitoring the pulse is crucial for digoxin administration.

Correct Answer: D

Rationale: The correct answer is D: Aspartate aminotransferase (AST) 60 units/L. An elevated AST level indicates liver damage, a side effect of methotrexate, and should be reported. Choices A, B, and C are within normal ranges and do not indicate potential complications related to methotrexate therapy.

Correct Answer: C

Rationale: In a client with thrombocytopenia, the platelet count is low, leading to a risk of bleeding. Providing a stool softener is essential to prevent constipation and straining during bowel movements, which can reduce the risk of bleeding episodes. Encouraging the client to floss daily (Choice A) is a good oral hygiene practice but is not directly related to thrombocytopenia. Removing fresh flowers from the client's room (Choice B) is related to infection control but does not address the specific risk of bleeding in thrombocytopenia. Avoiding serving the client raw vegetables (Choice D) is important in clients with neutropenia to prevent infections, not in thrombocytopenia.

Correct Answer: D

Rationale: In the scenario presented, the correct action for the nurse to take when caring for a client with a verbal prescription for restraints due to acute mania is to document the client's condition every 15 minutes. Documenting at regular intervals is essential to monitor the client's well-being, assess the effects of the restraints, and ensure the client's safety. Requesting a renewal of the prescription every 8 hours (Choice A) is not necessary as the focus should be on monitoring the client's condition. Checking the client's peripheral pulse every 30 minutes (Choice B) is important but not as crucial as documenting the overall condition. Obtaining a prescription for restraints within 4 hours (Choice C) is not the immediate action needed when a verbal prescription is already obtained.

Correct Answer: C

Rationale: The correct action the nurse should take when administering vancomycin IV is to assess the IV site for infiltration during administration. Vancomycin is known to cause tissue damage if it infiltrates, making close monitoring crucial. Administering the medication over 30 minutes (Choice A) is a common practice but not the priority in preventing infiltration. Monitoring for a decrease in blood pressure (Choice B) is not directly related to vancomycin administration. Premedicating with an antiemetic (Choice D) is not typically required for vancomycin administration.
