The nurse is caring for a patient with liver dysfunction. What is the maximum dose of acetaminophen the patient should receive in 24 hours?

A.

2g

B.

500 mg

C.

4g

D.

1g

Answer and Explanation

The Correct Answer is A

A. 2g is correct because for patients with liver dysfunction, the maximum recommended dose of acetaminophen is reduced to 2 grams per day to prevent hepatotoxicity.  
B. 500 mg is incorrect because while lower doses may be given at a time, the total daily limit for liver-compromised patients is higher than 500 mg.  
C. 4g is incorrect as this is the maximum dose for healthy adults with normal liver function, but it is too high for those with liver disease.  
D. 1g is incorrect because while it is a single-dose limit, the daily maximum for patients with liver dysfunction is 2g, not 1g.

Correct Answer is ["G"]

Explanation

A. History of type 2 diabetes is not a rhythm characteristic seen on an ECG. While diabetes can contribute to the development of cardiovascular issues, it does not specifically describe the characteristics of a third-degree AV block on an ECG.
B. Interval and RR interval are irregular is incorrect. In third-degree AV block (also known as complete heart block), the atrial rate and ventricular rate are typically regular, but the atrial and ventricular rhythms are completely dissociated.
C. Shortened PR interval is incorrect. In third-degree AV block, there is no consistent PR interval because the atria and ventricles are functioning independently.
D. Inconsistently shaped P waves is incorrect. P waves may appear normal, but the relationship between P waves and QRS complexes is lost in third-degree AV block.
E. PR interval is constant is incorrect. In third-degree AV block, the PR interval is inconsistent or absent, as the atrial and ventricular rates are independent of each other.
F. Apical heart rate is irrelevant here. The ECG will show the characteristic findings of third-degree AV block rather than focusing on apical heart rate alone.
G. Fewer QRS complexes than P waves is correct. In third-degree AV block, the atrial impulses (P waves) are conducted normally, but the ventricles are completely dissociated from the atrial rhythm, leading to fewer QRS complexes than P waves, as the ventricles may be paced by an escape rhythm.
H. PP interval is equal to RR interval is not necessarily true in third-degree AV block. The PP and RR intervals may be different depending on the escape rhythm, but they are not usually exactly equal.

Correct Answer is A

Explanation

A. Pneumothorax is a potential complication immediately following the insertion of a central venous catheter, especially with insertion through the subclavian vein. It occurs when the needle or catheter punctures the lung, allowing air to enter the pleural space. This is a critical, time-sensitive complication that needs immediate evaluation.
B. Central venous thrombosis is a concern over a longer period and is not an immediate complication following catheter insertion.
C. Hypoglycemia could occur later with TPN administration but is not an immediate concern following catheter placement.
D. Pulmonary aspiration is unrelated to the insertion of a central venous catheter. It is more relevant to issues with enteral feedings or swallowing difficulties.
