The nurse is conducting dietary teaching for a client diagnosed with coronary artery disease. Which statement made by the client indicates an understanding of fat sources and the need to limit saturated fats?

"Meat and eggs mostly contain unsaturated fats."

"Coconut oil has a rich flavor and is a good cooking oil."

"Olive oil is a monounsaturated fat and is recommended."

"Butter is high in saturated fats so I should avoid it."

Answer and Explanation

The Correct Answer is C

Choice A reason: This is not a correct statement. Meat and eggs mostly contain saturated fats, which are fats that have no double bonds between the carbon atoms. Saturated fats are solid at room temperature and can raise the level of low-density lipoprotein (LDL) cholesterol in the blood. LDL cholesterol is also known as the "bad" cholesterol because it can deposit on the walls of the arteries and cause atherosclerosis, which is the narrowing and hardening of the arteries. The client should limit the intake of saturated fats to less than 10% of the total calories per day.

Choice B reason: This is not a correct statement. Coconut oil is a saturated fat, which is a fat that has no double bonds between the carbon atoms. Coconut oil is solid at room temperature and can raise the level of low-density lipoprotein (LDL) cholesterol in the blood. LDL cholesterol is also known as the "bad" cholesterol because it can deposit on the walls of the arteries and cause atherosclerosis, which is the narrowing and hardening of the arteries. The client should avoid or limit the use of coconut oil and other sources of saturated fats.

Choice C reason: This is the correct statement. Olive oil is a monounsaturated fat, which is a fat that has one double bond between the carbon atoms. Monounsaturated fats are liquid at room temperature and can lower the level of low-density lipoprotein (LDL) cholesterol in the blood. LDL cholesterol is also known as the "bad" cholesterol because it can deposit on the walls of the arteries and cause atherosclerosis, which is the narrowing and hardening of the arteries. The client should use olive oil and other sources of monounsaturated fats instead of saturated fats.

Choice D reason: This is not a correct statement. Butter is high in saturated fats, which are fats that have no double bonds between the carbon atoms. Saturated fats are solid at room temperature and can raise the level of low-density lipoprotein (LDL) cholesterol in the blood. LDL cholesterol is also known as the "bad" cholesterol because it can deposit on the walls of the arteries and cause atherosclerosis, which is the narrowing and hardening of the arteries. The client should avoid or limit the intake of butter and other sources of saturated fats.

Correct Answer is D

Explanation

Choice A reason: Preparing for endotracheal intubation and ventilatory support is not the action that the nurse should take for a client with thyroid storm. This intervention is indicated for clients with respiratory failure or impending airway obstruction, which are not the case for this client.

Choice B reason: Providing continuous sedation for pain relief is not the action that the nurse should take for a client with thyroid storm. This intervention may worsen the client's condition by suppressing the respiratory drive and lowering the blood pressure. The nurse should administer antithyroid medications, beta blockers, and corticosteroids as prescribed to reduce the thyroid hormone levels and the associated symptoms.

Choice C reason: Initiating cardiac monitoring and assessing for reflex bradycardia is not the action that the nurse should take for a client with thyroid storm. This intervention is indicated for clients with hyperkalemia or digoxin toxicity, which are not the case for this client. The nurse should monitor the client's heart rate and rhythm, but not expect a reflex bradycardia, which is a paradoxical slowing of the heart rate in response to a rapid rise in blood pressure.

Choice D reason: Maintaining IV fluid infusion and assessing adequacy of hydration is the action that the nurse should take for a client with thyroid storm. This intervention is indicated for clients with thyroid storm, as they are at risk of dehydration and electrolyte imbalance due to increased metabolic rate, fever, sweating, vomiting, and diarrhea. The nurse should administer isotonic fluids, such as normal saline, and monitor the client's fluid intake and output, urine specific gravity, and serum electrolytes.

A. International normalized ratio 1.3 seconds B. Hemoglobin 14 g/dL C. Serum iron 150 mcg/dL D. Platelet count 250,000/mm3

Correct Answer is B

Explanation

Choice A reason: The international normalized ratio (INR) is a measure of the blood's ability to clot. It is not affected by ferrous sulfate therapy, which is used to treat iron deficiency anemia. The normal range of INR is 0.8 to 1.2 seconds.

Choice B reason: Hemoglobin is the protein in red blood cells that carries oxygen. It is the main indicator of anemia and the response to iron therapy. The normal range of hemoglobin for adults is 12 to 18 g/dL. A hemoglobin level of 14 g/dL suggests that the patient's anemia has improved with ferrous sulfate therapy.

Choice C reason: Serum iron is the amount of iron in the blood. It is not a reliable indicator of anemia or iron therapy, as it can fluctuate with dietary intake, infection, inflammation, and other factors. The normal range of serum iron for adults is 50 to 170 mcg/dL.

Choice D reason: Platelet count is the number of platelets in the blood. Platelets are involved in blood clotting and wound healing. They are not affected by ferrous sulfate therapy, which is used to treat iron deficiency anemia. The normal range of platelet count for adults is 150,000 to 450,000/mm3.
