A nurse is reviewing the laboratory results of a client who has ﬂuid volume deficit. The nurse would expect which of the following findings?

Sodium 155 mEq/L

Hematocrit 44%

Urine specific gravity 1.035

BUN 19 mg/dL

Answer and Explanation

The Correct Answer is C

Choice A: Sodium 155 mEq/L is correct because it indicates hypernatremia, or high sodium level, which can occur in ﬂuid volume deficit due to dehydration, excessive sweating, or diuretic therapy. Sodium is an electrolyte that regulates ﬂuid balance and osmotic pressure in the body. The normal range of sodium is 135 to 145 mEq/L.

Choice B: Hematocrit 44% is incorrect because it is within the normal range of hematocrit, which is the percentage of red blood cells in the blood. Hematocrit can reﬂect the oxygen-carrying capacity and viscosity of the blood. The normal range of hematocrit is 37% to 47% for females and 42% to 52% for males.

Choice C: Urine specific gravity 1.035 is correct because it indicates a high urine concentration, which can occur in ﬂuid volume deficit due to decreased urine output and increased solute excretion. Urine specific gravity is a measure of the density of urine compared to water. The normal range of urine specific gravity is 1.005 to 1.030.

Choice D: BUN 19 mg/dL is incorrect because it is within the normal range of BUN, which stands for blood urea nitrogen, and is a measure of the amount of nitrogen in the blood that comes from urea, a waste product of protein metabolism. BUN can reﬂect the kidney function and hydration status of the client. The normal range of BUN is 7 to 20 mg/dL.

Correct Answer is A

Explanation

Choice A: Digoxin is correct because it is a medication that can cause visual disturbances, such as blurred vision, yellow-green halos, or photophobia, as a sign of digoxin toxicity. Digoxin toxicity can occur when the serum digoxin level exceeds the therapeutic range of 0.5 to 2 ng/mL. Digoxin toxicity can also cause nausea, vomiting, anorexia, confusion, bradycardia, and cardiac arrhythmias. The risk of digoxin toxicity is increased by hypokalemia, which can lower the threshold for digoxin action and enhance its eﬀects on the cardiac muscle.

Choice B: Aspirin is incorrect because it is a medication that can cause gastrointestinal bleeding, tinnitus, or allergic reactions, but not visual disturbances. Aspirin is an antiplatelet and anti-inﬂammatory medication that can be used to prevent thromboembolic events, such as stroke or myocardial infarction, in patients with atrial fibrillation.

Choice C: Potassium chloride is incorrect because it is a medication that can cause hyperkalemia, or high potassium level, if taken in excess or in combination with other potassium-sparing drugs, but not visual disturbances. Potassium chloride is a supplement that can be used to treat or prevent hypokalemia, or low potassium level, in patients who are taking diuretics or have other causes of potassium loss.

Choice D: Warfarin is incorrect because it is a medication that can cause bleeding, bruising, or hematoma formation, but not visual disturbances. Warfarin is an anticoagulant that can be used to prevent thromboembolic events, such as stroke or pulmonary embolism, in patients with atrial fibrillation.

A. Corticosteroid B. Narcotic C. Thiazide diuretic D. Muscle relaxer

Correct Answer is C

Explanation

Choice A: Corticosteroid is incorrect because it does not directly aﬀect the potassium level in the blood, although it can cause sodium and water retention, which can dilute the potassium concentration. Corticosteroid is a type of anti- inﬂammatory medication that can be used to treat conditions such as asthma, arthritis, or allergic reactions.

Choice B: Narcotic is incorrect because it does not directly aﬀect the potassium level in the blood, although it can cause respiratory depression, which can lead to respiratory acidosis and hyperkalemia, or high potassium level. Narcotic is a type of analgesic medication that can be used to treat moderate to severe pain.

Choice C: Thiazide diuretic is correct because it is a type of medication that increases urine output and sodium excretion, but also causes potassium loss in the urine. Thiazide diuretic can be used to treat conditions such as hypertension, edema, or heart failure.

Choice D: Muscle relaxer is incorrect because it does not directly aﬀect the potassium level in the blood, although it can cause muscle weakness, which can mimic the symptoms of hypokalemia. Muscle relaxer is a type of medication that can be used to treat conditions such as muscle spasms, back pain, or fibromyalgia.
