Which signs would alert the nurse to possible nutritional alterations? (Select all that apply, one, some, or all.)

A. Physiologic indicators can be helpful in pain assessment, but they are not directly linked to pain intensity scales, which are focused on subjective reports.
B. Pain intensity scales still involve a subjective component, as they rely on the patient’s report of their pain, even if the scale itself is structured.
C. A specific pain intensity scale provides consistency in how pain is assessed, allowing for more reliable tracking and management of pain across different shifts and caregivers.
D. While pain scales include subjective reports, they do not focus solely on objective data. The goal is to measure the patient's perception of pain.

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.
