Correct Answer: B

Rationale: The correct answer is B. Potassium levels above 5.0 mEq/L can lead to cardiac issues, and a level of 6.5 mEq/L requires immediate intervention. Hyperkalemia can cause life-threatening cardiac arrhythmias.

Choices A, C, and D are within normal ranges and do not require immediate intervention in the context of hemodialysis monitoring.

Correct Answer: D

Rationale: Correct. Bradycardia is a known adverse effect of atenolol, a beta-blocker medication commonly used to treat hypertension. Atenolol can slow down the heart rate, leading to bradycardia. The nurse should monitor the client for signs of bradycardia, such as dizziness, fatigue, or fainting.

Choices A, B, and C are incorrect because cough, tremor, and constipation are not typically associated with atenolol use.

Correct Answer: B

Rationale: The correct answer is B. Bruising on the arms and legs is a sign of bleeding, which is a serious complication of heparin therapy and should be reported immediately to the provider. Option A is incorrect as urine output greater than 30 mL/hr is a normal finding. Option C, positive Trousseau's sign, is associated with hypocalcemia, not heparin therapy. Option D, urine output of 60 mL/hr, is within the normal range and does not indicate a complication of heparin therapy.

Correct Answer: D

Rationale: The correct answer is D. When a client is prescribed warfarin, they should be educated to report any unusual bleeding or bruising promptly.

Choices A, B, and C are incorrect. Avoiding foods rich in vitamin K is not necessary when taking warfarin, as long as intake remains consistent. Warfarin does not need to be taken with meals, and aspirin should not be taken for pain relief due to its blood-thinning effects, which can increase the risk of bleeding when combined with warfarin.
