A client with alcoholism is admitted to a medical-surgical unit with a serum magnesium level of 0.9 mEq/L. Which clinical manifestations would the nurse expect to find in this client?

Tremors and twitching

Positive Chvostek's sign

Decreased deep tendon reflexes

Polyuria and flank pain

Answer and Explanation

The Correct Answer is A

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.

Correct Answer is B

Explanation

Choice A reason: Glucose of 110 mg/dL is not a finding that indicates digoxin toxicity. It is a normal blood glucose level for a fasting or non-fasting client.

Choice B reason: Potassium of 3.0 mEq/L is a finding that indicates digoxin toxicity. It is a low serum potassium level, which increases the risk of digoxin toxicity by enhancing the binding of digoxin to cardiac cells. The nurse should monitor the client for signs and symptoms of digoxin toxicity, such as nausea, vomiting, anorexia, fatigue, confusion, visual disturbances, and cardiac arrhythmias.

Choice C reason: Calcium of 9.0 mg/dL is not a finding that indicates digoxin toxicity. It is a normal serum calcium level for an adult client.

Choice D reason: Sodium of 133 mEq/L is not a finding that indicates digoxin toxicity. It is a slightly low serum sodium level, which may indicate hyponatremia, but not digoxin toxicity.

A. You feel good because your medication is working properly. B. Your blood pressure reflects how strong your heart muscle contracts. C. Even if you are feeling good, damage can occur to your heart and kidneys. D. Have you told your doctor that you are feeling good?

Correct Answer is C

Explanation

Choice A reason: You feel good because your medication is working properly is not the most appropriate statement by the nurse. This statement may imply that the client does not need to worry about their blood pressure or follow up with their doctor. The nurse should educate the client about the importance of regular monitoring and adherence to the prescribed treatment.

Choice B reason: Your blood pressure reflects how strong your heart muscle contracts is not the most appropriate statement by the nurse. This statement may confuse the client or give them a false sense of security. The nurse should explain that blood pressure is determined by the force and amount of blood pumped by the heart and the resistance of the blood vessels. The nurse should also inform the client about the normal and abnormal ranges of blood pressure and the risk factors for hypertension.

Choice C reason: Even if you are feeling good, damage can occur to your heart and kidneys is the most appropriate statement by the nurse. This statement conveys the seriousness of hypertension and its potential complications. The nurse should educate the client about the effects of high blood pressure on the vital organs and the need for preventive measures and lifestyle modifications.

Choice D reason: Have you told your doctor that you are feeling good is not the most appropriate statement by the nurse. This statement may suggest that the nurse is not interested in the client's condition or does not have the knowledge or authority to address their concerns. The nurse should communicate effectively with the client and the health care team and provide appropriate guidance and support.
