Answer and Explanation

The Correct Answer is C

Sinus bradycardia is a type of cardiac arrhythmia characterized by a heart rate lower than 60 beats per minute in adults, or below the normal range for age in children. It can be diagnosed by an electrocardiogram (ECG) that shows regular P waves with constant morphology preceding every QRS complex, and positive in lead II.

Correct Answer is A

Explanation

The ABG results show a low pH (acidosis), a high PaCO2 (respiratory component), and a normal HCO3 (metabolic component). This indicates respiratory acidosis, which is caused by hypoventilation and retention of carbon dioxide.

A. Creatinine 0.8 mL/dL B. Weight gain 1.1 kg (2.4 lb) in 24 hr C. Peripheral pulses 2+ bilaterally D. Urine specific gravity 1.045

Correct Answer is B

Explanation

Weight gain 1.1 kg (2.4 lb) in 24 hours indicates fluid retention and possible volume overload, which can worsen kidney function and cause complications such as hypertension, pulmonary edema, and heart failure. The nurse should report this finding to the provider and monitor the client's vital signs, fluid intake and output, and electrolyte levels.

Creatinine 0.8 mL/dL is within the normal range for adults and does not indicate kidney impairment. Peripheral pulses 2+ bilaterally are normal and do not suggest any vascular problems. Urine specific gravity 1.045 is slightly high but not abnormal for a client with acute kidney failure, as it reflects the reduced ability of the kidneys to dilute urine.
