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. Deferasirox is a medication used to treat chronic iron overload due to blood transfusions. It is not used as an antidote for heparin.
B. Protamine sulfate is the antidote for heparin. It works by binding to heparin, neutralizing its anticoagulant effects. Protamine sulfate is typically used in cases of heparin overdose or when rapid reversal of heparin's effects is necessary, such as during surgery or if there is active bleeding.
C. Acetylcysteine is used as an antidote for acetaminophen (paracetamol) overdose due to its ability to replenish glutathione stores in the liver and protect against liver damage. It has no role in reversing heparin's effects.
D. Vitamin K is the antidote for warfarin, not heparin. It promotes the synthesis of clotting factors in the liver that are inhibited by warfarin, thus reversing its anticoagulant effects.

A. Metabolic alkalosis B. Respiratory alkalosis C. Metabolic acidosis D. Respiratory acidosis

Correct Answer is D

Explanation

A. Metabolic alkalosis is characterized by an increase in bicarbonate (HCO3-) levels in the blood, resulting in an elevated pH (>7.45). Shallow respirations are less likely to cause metabolic alkalosis directly.
B. This is not likely the initial risk. Respiratory alkalosis occurs due to hyperventilation, leading to excessive elimination of CO2 (carbon dioxide), which raises the blood pH (>7.45). Shallow respirations typically result in retention of CO2, leading to respiratory acidosis rather than alkalosis.
C. Metabolic acidosis occurs when there is an increase in acid (decreased pH <7.35) or a decrease in bicarbonate levels in the blood. Shallow respirations can lead to hypoventilation and retention of CO2, resulting in respiratory acidosis initially.
D. Shallow respirations at a rate of 9 breaths per minute reduce the elimination of CO2, leading to its accumulation in the blood. This accumulation lowers the blood pH (<7.35), causing respiratory acidosis. Therefore, the client is initially at risk for developing respiratory acidosis due to ineffective ventilation.
