Correct Answer: B

Rationale: The correct answer is B: A chicken breast. Chicken breast is low in potassium, making it a safe option for clients with chronic kidney disease who need to limit their potassium intake. Foods like bananas and orange juice are high in potassium, which should be avoided or limited by individuals with chronic kidney disease to prevent further kidney damage.

Correct Answer: B

Rationale: Bacterial vaginosis often presents with a profuse, milky white discharge and a characteristic fishy odor, without significant inflammation, hematuria, or fever. Choice A, frequency, and dysuria are more indicative of a urinary tract infection. Choice C, hematuria, is associated with conditions like urinary tract infections or kidney problems. Choice D, low-grade fever, is not a typical symptom of bacterial vaginosis.

Correct Answer: B

Rationale: A PaCO2 level of 55 mm Hg indicates hypercapnia, which is common in clients with emphysema but may require further treatment if it leads to respiratory acidosis or distress. Elevated PaCO2 levels can indicate inadequate ventilation and impaired gas exchange, potentially leading to respiratory acidosis. The other results fall within normal ranges or compensated values for a client with chronic emphysema and do not necessarily indicate the need for immediate intervention.

Correct Answer: C

Rationale: A temperature of 38.2°C (100.8°F) suggests the possibility of an underlying infection or fever, which should be evaluated before proceeding with the transfusion to prevent complications. Elevated temperature can indicate an immune response to incompatible blood components, increasing the risk of a transfusion reaction. The other vital signs and lab results provided are within acceptable ranges for administering packed RBCs, making choices A, B, and D less likely to cause a delay in the transfusion.

Correct Answer: A

Rationale: The correct answer is A. Clients with chronic kidney disease should limit their intake of phosphorus because high phosphorus levels can lead to bone disease and cardiovascular problems. Increasing foods high in potassium (choice B) is not recommended as it can be harmful to individuals with kidney disease. Decreasing intake of foods high in iron (choice C) is not specifically indicated for chronic kidney disease. Increasing calcium supplements (choice D) may not be necessary and can potentially lead to hypercalcemia in individuals with kidney disease.
