Concepts for Nursing Practice Giddens Test Bank

Correct Answer: D

Rationale: Creatinine clearance is a diagnostic test that helps determine both the glomerular filtration rate (GFR) and the extent of glomerular damage in the renal system. Creatinine is a waste product produced by muscles and excreted by the kidneys. A decrease in the glomerular filtration rate indicates impaired kidney function, which could be due to glomerular damage or other renal issues. By measuring the amount of creatinine in the blood and urine over a specific period of time, creatinine clearance provides an estimate of the GFR. This test is commonly used to assess kidney function in patients with renal disease or renal impairment.

Correct Answer: B

Rationale: - Compression stockings help promote blood circulation in the legs, decreasing the risk of blood clots forming. This is important after surgery, especially in older adults who may have a higher risk.

Correct Answer: A

Rationale: Acute postinfectious glomerulonephritis is commonly associated with a preceding streptococcal infection, particularly strep throat. This inflammatory condition affects the glomeruli in the kidneys and can result in symptoms such as hematuria, proteinuria, hypertension, and edema. Therefore, asking the patient about recent strep throat can help establish a potential link to the development of acute postinfectious glomerulonephritis.

Correct Answer: A

Rationale: A neurovascular assessment is performed to evaluate nerve function, circulation, and tissue perfusion. Pale, cold fingers indicate poor circulation, which can be a sign of compromised blood flow from the cast causing decreased oxygen supply to the tissues. This finding is concerning as it suggests potential nerve or vascular compromise, which could lead to serious complications if not addressed promptly. It is important for the nurse to report this finding to the healthcare provider for further evaluation and intervention.

Correct Answer: D

Rationale: Torsades de Pointes is a specific type of ventricular tachycardia characterized by a distinctive twisting pattern on an ECG. It is often associated with a prolonged QT interval and can potentially lead to a life-threatening arrhythmia known as ventricular fibrillation. Sinus tachycardia, atrial flutter, and junctional escape rhythms are not forms of ventricular tachycardia.
