Correct Answer: D

Rationale: The correct action the nurse should take when administering multiple medications to a client with an enteral feeding tube is to flush the tube with 15-30 mL of sterile water before and between medications, and 30-60 mL after the last medication. This helps prevent clogging and ensures each medication is delivered effectively. Choice A is incorrect as medications should not be dissolved in water for administration through an enteral feeding tube. Choice B is incorrect because each medication should be drawn up and administered separately to prevent any potential interactions. Choice C is incorrect as resistance while pushing the plunger may indicate a problem that needs to be addressed before continuing with the administration.

Correct Answer: D

Rationale: The correct answer is 'D: I can take aspirin if I have a headache.' This statement indicates a need for further teaching because aspirin can increase the risk of bleeding in clients taking warfarin. Clients on warfarin therapy should avoid taking aspirin or any other medications that can increase the risk of bleeding without consulting their healthcare provider. Choices A, B, and C are correct statements that demonstrate understanding of warfarin therapy and its potential side effects. Avoiding foods high in vitamin K helps maintain the effectiveness of warfarin, taking medication at the same time every day ensures consistent therapeutic levels, and using a soft toothbrush helps prevent gum bleeding, which can be a side effect of warfarin therapy.

Correct Answer: A

Rationale: The nurse should prioritize seeing the patient with a hip replacement on prolonged bed rest reporting chest pain and dyspnea first. This patient is at higher risk for deep vein thrombosis due to prolonged bed rest, which can lead to a life-threatening embolus. Chest pain and dyspnea could also indicate a potential pulmonary embolism, which requires immediate assessment and intervention. The other patients, while requiring care, do not present with symptoms that suggest an immediate life-threatening situation, making them lower priority at this time. Therefore, option A is the correct choice as it addresses a potentially critical condition that requires immediate attention.

Correct Answer: D

Rationale: The correct answer is to initiate contact precautions when providing client care. C-diff (Clostridium difficile) is highly contagious, and contact precautions are necessary to prevent its spread. Giving the client chlorhexidine gluconate for hand hygiene (Choice A) is not specific to managing C-diff. Removing the protective gown first when exiting the client's room (Choice B) may increase the risk of contaminating oneself and the environment. Using alcohol-based hand rub when caring for the client (Choice C) is not sufficient to prevent the transmission of C-diff, as soap and water are more effective against this particular pathogen.

Correct Answer: D

Rationale: The correct answer is D. A potassium level of 5.4 mEq/L is above the expected reference range, indicating hyperkalemia. Hyperkalemia can lead to serious complications such as dysrhythmias, making it important for the healthcare professional to report this finding to the provider for further evaluation and intervention. Choices A, B, and C fall within normal ranges and do not pose an immediate risk to the client's health, so they would not warrant immediate reporting to the provider. Elevated BUN or creatinine levels may indicate kidney dysfunction, while a sodium level of 143 mEq/L falls within the normal range for adults and does not typically require urgent intervention.
