The nurse is teaching a client with hypertension about the prescribed hydrochlorothiazide 10 mg PO daily. Which statement, made by the client, would indicate that the teaching has been effective? "I will:

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.

Choice A reason: This is the correct answer. Tremors and twitching are signs of hypomagnesemia, which is a low level of magnesium in the blood. Magnesium is a mineral that is involved in many enzymatic reactions and neuromuscular functions. A low magnesium level can cause hyperexcitability of the nerves and muscles, leading to involuntary movements and spasms. Alcoholism can cause hypomagnesemia by reducing the absorption and increasing the excretion of magnesium.

Choice B reason: Positive Chvostek's sign is not a sign of hypomagnesemia, but of hypocalcemia, which is a low level of calcium in the blood. Calcium is another mineral that is important for the function of nerves and muscles. A low calcium level can cause tetany, which is a condition of sustained muscle contraction. Chvostek's sign is a test that involves tapping the facial nerve in front of the ear and observing for a twitching of the facial muscles. A positive Chvostek's sign indicates hypocalcemia, not hypomagnesemia.

Choice C reason: Decreased deep tendon reflexes are not a sign of hypomagnesemia, but of hypermagnesemia, which is a high level of magnesium in the blood. A high magnesium level can cause hyporeflexia, which is a reduced or absent response to stimuli. Magnesium has a sedative effect on the nerves and muscles, and can inhibit the transmission of impulses. Hypermagnesemia can be caused by excessive intake or impaired excretion of magnesium.

Choice D reason: Polyuria and flank pain are not signs of hypomagnesemia, but of kidney problems, such as infection, stones, or failure. Polyuria is the production of abnormally large amounts of urine, and flank pain is the pain in the side or back below the ribs. These symptoms can indicate damage or inflammation of the kidneys, which can affect the balance of fluids and electrolytes in the body. Hypomagnesemia does not directly cause polyuria or flank pain, but it can be a result of kidney dysfunction.
