Correct Answer: C

Rationale: The correct answer is C. A potassium level of 2.8 mEq/L is low and should be reported to the provider. Furosemide can cause potassium depletion, leading to hypokalemia. Low potassium levels can result in cardiac dysrhythmias, which is a serious concern in clients with heart failure. Choices A, B, and D are within normal ranges and do not require immediate reporting. Sodium level of 140 mEq/L, heart rate of 82/min, and oxygen saturation of 95% are all acceptable findings.

Correct Answer: D

Rationale: A weight gain of 1 kg in 24 hours can indicate fluid retention and worsening heart failure, requiring an increase in diuresis. This finding suggests that the current diuretic therapy is not effective enough to manage the fluid overload, necessitating an increase in the infusion rate of furosemide. Choices A, B, and C are not directly related to the need for an increase in diuretic therapy in heart failure patients. Urine output of 20 mL/hr, a heart rate of 90/min, and a sodium level of 138 mEq/L are important parameters to monitor but do not specifically indicate the need to increase the infusion rate of furosemide.

Correct Answer: A

Rationale: The correct answer is A: 'I will avoid crowded places to reduce my risk of infection.' When taking prednisone, clients should avoid crowded places to reduce the risk of infection due to its immunosuppressive effects. Choice B is incorrect because prednisone is usually taken with food to reduce stomach upset. Choice C is incorrect because clients should not stop taking prednisone abruptly, even if they experience nausea. Choice D is incorrect because prednisone should be tapered off gradually under healthcare provider guidance instead of being stopped abruptly after 2 weeks.

Correct Answer: B

Rationale: Using a 7th-grade reading level is the most effective technique when creating education material for clients because it ensures that the content is easily understood by a wide range of individuals. Option A, emphasizing important information with bold lettering, may help draw attention but doesn't guarantee comprehension. Option C, avoiding cartoons, is not necessarily a universal rule and can sometimes make material more engaging. Option D, using words with three or four syllables, can make the material more complex and harder to understand, defeating the purpose of effective communication in education material.

Correct Answer: A

Rationale: The correct answer is A. Lisinopril can increase potassium levels, so clients should avoid salt substitutes that contain potassium. Choice B is incorrect because lisinopril is usually taken on an empty stomach. Choice C is incorrect because lisinopril can lead to hyperkalemia, so increasing potassium-rich foods is not recommended. Choice D is incorrect because lisinopril can cause increased urination, so fluid intake should not be limited.
