Correct Answer: B

Rationale: The correct answer is B: Dyspnea. Dyspnea, or difficulty breathing, is a common sign of fluid overload in a client receiving packed RBCs. When fluid accumulates in the lungs due to overload, it can lead to respiratory distress. This finding requires prompt intervention to prevent further complications. Choices A, C, and D are incorrect: A) Low back pain is not typically associated with fluid overload; C) Hypotension refers to low blood pressure and is not a typical finding in fluid overload; D) Thready pulse may indicate poor perfusion but is not a direct indicator of fluid overload.

Correct Answer: D

Rationale: The correct answer is D: Decreased deep tendon reflexes. In myasthenia gravis, muscle weakness is a common manifestation, leading to decreased deep tendon reflexes. Bradycardia (choice A) is not typically associated with myasthenia gravis. Increased muscle strength (choice B) is unlikely as muscle weakness is a hallmark of this condition. Diarrhea (choice C) is not a typical finding in myasthenia gravis.

Correct Answer: C

Rationale: The correct answer is C: 'Take medications at the same time every day.' Consistency in medication administration is crucial for stroke recovery to maintain therapeutic drug levels in the body. Choice A, 'Avoid lifting more than 5 pounds,' though important to prevent strain, is not directly related to medication adherence. Choice B, 'Perform range-of-motion exercises daily,' is beneficial for overall recovery but is not specific to medication management. Choice D, 'Monitor blood pressure daily,' is important but does not address the key aspect of medication regimen adherence.

Correct Answer: C

Rationale: The correct answer is C: Heart rate of 60/min. A heart rate of 60/min is borderline bradycardia, which can be a sign of digoxin toxicity. Digoxin can cause bradycardia, so any further decrease in heart rate should be reported promptly to the healthcare provider. Choices A, B, and D are within the normal range and not specifically related to potential digoxin toxicity, so they do not require immediate reporting.

Correct Answer: C

Rationale: A temperature of 37.8°C (100°F) should be reported to the provider as it can indicate infection, a common postoperative complication. A normal heart rate of 80/min (Choice A), white blood cell count of 9,000/mm3 (Choice B), and blood pressure of 118/78 mm Hg (Choice D) are within normal ranges and do not necessarily indicate a complication postoperatively.
