An 85-year-old patient who has fallen at home and was unable to get up is admitted to your nursing unit. The patient said she fell 36 hours ago and has been unable to eat or drink. You observe that the patient has voided scant amounts since admission. In planning care for this patient, what condition do you consider related to the diminished renal output?

Renal calculi

Hypovolemia

inactivity

Nephrotoxic drugs

Answer and Explanation

The Correct Answer is B

A.   While renal calculi (kidney stones) can cause renal issues, they are not directly related to diminished renal output in this scenario. Hypovolemia, or low blood volume, is more pertinent to the patient's presentation of scant voiding and inability to eat or drink.
B.   Diminished renal output, as evidenced by scant voiding, can be indicative of hypovolemia. Hypovolemia reduces kidney perfusion, leading to decreased urine output as the kidneys conserve fluid.
C.   While inactivity can contribute to various health issues, it's not directly related to diminished renal output in this case. The primary concern is addressing the immediate physiological impact of decreased renal function.

D.   While nephrotoxic drugs can impair renal function, there's no indication in the scenario that the patient has been exposed to such drugs. Thus, they are not directly relevant to the current situation.

Correct Answer is C

Explanation

A. Orange, could also indicate dehydration, but it may also be caused by certain medications or foods, so it is not as specific as dark amber for dehydration.
B. Smoky urine is often associated with blood in the urine, which can result from various conditions but is not specific to dehydration.
C. Dehydration occurs when the body loses more fluids than it takes in, leading to a higher concentration of waste products in the urine, which gives it a dark amber color. This is because with less water to dilute them, the naturally occurring minerals and chemicals in the urine become more concentrated.
D. Green urine is not typically associated with dehydration and may indicate other underlying conditions or the presence of certain medications or foods.

A. Atrial fibrillation B. Asystole C. Ventricular fibrillation D. Atrial flutter

Correct Answer is B

Explanation

A. Atrial fibrillation is characterized by rapid, irregular electrical impulses originating from the atria, resulting in a quivering or fibrillating motion of the atria rather than a coordinated contraction.
B. Asystole is the absence of any electrical activity on the cardiac monitor, resulting in a flat line. It indicates the absence of ventricular contraction and is considered a medical emergency requiring immediate intervention (CPR and advanced cardiac life support).
C. Ventricular fibrillation is characterized by chaotic, disorganized electrical activity in the ventricles, resulting in ineffective quivering of the ventricles and loss of cardiac output.
D. Atrial flutter is characterized by rapid but regular electrical impulses originating from the atria, resulting in a sawtooth pattern on the ECG tracing.
