The nurse is assessing a client with a head injury Which finding would indicate that the client is developing diabetes insipidus?
Urine glucose, high
Urine specific gravity, 1.001
Urine output, 50 ml/hr
Urine protein, high
The Correct Answer is B
A. Urine glucose, high: High urine glucose would suggest hyperglycemia, typically seen in diabetes mellitus, not diabetes insipidus.
B. Urine specific gravity, 1.001: Diabetes insipidus results in excessive urine output with a low specific gravity (dilute urine), reflecting the inability to concentrate urine.
C. Urine output, 50 ml/hr: This is a relatively low urine output, which does not indicate diabetes insipidus. Diabetes insipidus is characterized by very high urine output, often greater than 3 liters per day.
D. Urine protein, high: High urine protein could suggest kidney disease or glomerular injury, not diabetes insipidus.

Correct Answer is B
Explanation
A. Junctional tachycardia: Junctional tachycardia originates from the atrioventricular (AV) node, with a faster rate and usually no visible P waves preceding the QRS complexes.
B. Sinus tachycardia: Sinus tachycardia is characterized by a regular, rapid heart rhythm originating from the sinus node, typically seen after exercise, with identifiable P waves before each QRS complex.
C. Atrial flutter: Atrial flutter presents with a “sawtooth” pattern of P waves, indicating rapid atrial contractions, which is different from sinus tachycardia.
D. Ventricular fibrillation: Ventricular fibrillation is a chaotic and irregular rhythm originating from the ventricles, which is a life-threatening condition.
Correct Answer is B
Explanation
A. Sinus rhythm with first-degree heart block: This rhythm is characterized by a regular sinus rhythm with a prolonged PR interval (greater than 0.20 seconds), indicating a first-degree heart block.
B. ST-segment elevation myocardial infarction (STEMI): STEMI is indicated by significant ST-segment elevation in specific leads, showing acute myocardial infarction.
C. Atrial fibrillation: Atrial fibrillation shows an irregularly irregular rhythm without distinct P waves.
D. Ventricular tachycardia: Ventricular tachycardia is a rapid heart rhythm originating from the ventricles, with wide QRS complexes and no preceding P waves.
