A patient is admited with hypernatremia caused by being stranded on a boat in the Atlantic Ocean for two days without water. What is the patient at risk for developing?

Cerebral bleeding

Pulmonary edema

Cardiac arrhythmias

Seizures

Answer and Explanation

The Correct Answer is C

Choice A: Cerebral bleeding is incorrect because it is not a common complication of hypernatremia, which is a high sodium level in the blood. Cerebral bleeding can be caused by conditions such as head trauma, stroke, or aneurysm.

Choice B: Pulmonary edema is incorrect because it is a condition where ﬂuid accumulates in the lungs, causing shortness of breath, coughing, and wheezing. Pulmonary edema can be caused by conditions such as heart failure, kidney failure, or lung injury.

Choice C: Cardiac arrhythmias is correct because it is a condition where the heart beats irregularly, too fast, or too slow. Cardiac arrhythmias can be caused by hypernatremia, which can aﬀect the electrical activity and contractility of the heart muscle. Hypernatremia can also cause dehydration, hypovolemia, and hypotension, which can impair the blood ﬂow and oxygen delivery to the heart.

Choice D: Seizures is incorrect because it is a condition where abnormal electrical activity in the brain causes convulsions, loss of consciousness, or altered behavior. Seizures can be caused by conditions such as epilepsy, brain tumor, or infection.

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.

A. Sodium level B. Daily weight C. Intake and output D. Tissue turgor

Correct Answer is B

Explanation

Choice A: Sodium level is not a reliable measure of ﬂuid retention because it can be aﬀected by other factors such as diet, medication, and dehydration. Sodium level does not reﬂect the amount of water in the body.

Choice B: Daily weight is the most reliable measure of ﬂuid retention because it reﬂects the changes in total body water. A weight gain of more than 0.5 kg (1 lb) in a day or 1.5 kg (3 lb) in a week indicates ﬂuid retention.

Choice C: Intake and output is not a reliable measure of ﬂuid retention because it does not account for insensible losses such as sweating, breathing, and fever. Intake and output can also be inaccurate due to measurement errors or incomplete records.

Choice D: Tissue turgor is not a reliable measure of ﬂuid retention because it can be inﬂuenced by age, skin elasticity, and hydration status. Tissue turgor does not indicate the amount of ﬂuid in the intravascular space.
