A nurse is reviewing the laboratory results for a client who has a history of atherosclerosis and notes elevated cholesterol levels. Which of the following statements by the client indicates the nurse should plan follow-up teaching on a low-cholesterol diet?

"I cook my food with canola oil."

"I eat two eggs for breakfast each morning

"I flavor my meat with lemon juice."

"I take an omega-3 supplement daily."

Answer and Explanation

The Correct Answer is B

A.   Canola oil is a healthier option compared to oils high in saturated fats, such as butter or lard. It does not significantly contribute to dietary cholesterol intake. Therefore, this statement does not indicate a need for follow-up teaching on a low-cholesterol diet.
B.   Eggs are high in dietary cholesterol, and consuming two eggs daily can significantly increase cholesterol intake. For someone with elevated cholesterol levels or a history of atherosclerosis, this dietary habit may contribute to further elevation of cholesterol levels and potentially worsen cardiovascular health. Hence, this statement indicates the need for follow-up teaching on reducing dietary cholesterol intake.
C.   Lemon juice is a low-calorie and low-cholesterol flavoring option. It does not significantly impact cholesterol intake. Therefore, this statement does not indicate a need for follow-up teaching on a low- cholesterol diet.
D.   Omega-3 fatty acids are beneficial for heart health and do not contribute to dietary cholesterol intake. In fact, they may help reduce triglyceride levels and inflammation. Therefore, this statement does not indicate a need for follow-up teaching on a low-cholesterol diet.

Correct Answer is B

Explanation

A. It is particularly sensitive to deficiencies in clotting factors, but it does not measure the deficiencies themselves
B. The activated partial thromboplastin time (aPTT) test measures the effectiveness of the intrinsic and common pathways of the coagulation cascade.
C. There is no need to skip breakfast or alter diet for an aPTT test. It is not affected by food intake or fasting status.

D. While aPTT is used to monitor heparin therapy, it is not typically used to monitor warfarin (a vitamin K antagonist) therapy. Warfarin therapy is usually monitored using the prothrombin time (PT) and international normalized ratio (INR) tests.

A. Hypophosphatemia B. Hypernatremia C. Hypercalcemia D. Hyperkalemia

Correct Answer is D

Explanation

A. Hypophosphatemia refers to low levels of phosphate in the blood. In prerenal AKI, phosphate levels are typically normal or even elevated due to reduced kidney function and impaired phosphate excretion. Therefore, hypophosphatemia is not expected in prerenal AKI.
B. Hypernatremia refers to high levels of sodium in the blood. In prerenal AKI, sodium levels can be elevated due to reduced kidney function and impaired ability to excrete sodium. This occurs because the kidneys play a crucial role in regulating sodium balance. Therefore, hypernatremia is a possible electrolyte imbalance in prerenal AKI.
C. Hypercalcemia refers to high levels of calcium in the blood. In prerenal AKI, calcium levels are usually normal or decreased due to various factors, including reduced renal excretion of calcium. Therefore, hypercalcemia is not typically seen in prerenal AKI.
D. Hyperkalemia refers to high levels of potassium in the blood. In prerenal AKI, hyperkalemia is a common electrolyte imbalance. Normally, the kidneys play a critical role in potassium excretion. Reduced kidney function in prerenal AKI can lead to impaired potassium excretion, resulting in elevated potassium levels in the blood.
