A nurse is completing discharge teaching with a client who has a peripherally inserted central catheter (PICC) line in the left arm.
Which of the following instructions should the nurse include in the teaching?
Clean the insertion site using 20 mL of hydrogen peroxide.
Change the catheter dressing daily.
Use a 10-mL syringe to flush the line.
Do not elevate the arm above the level of the heart.
The Correct Answer is C
A 10-mL syringe is the minimum size that should be used to flush a PICC line to prevent damage to the catheter.
Choice A, Clean the insertion site using 20 mL of hydrogen peroxide, is not the correct answer because hydrogen peroxide should not be used to clean the insertion site of a PICC line.
Choice B, Changing the catheter dressing daily, is not the correct answer because the catheter dressing should be changed every 3 to 7 days or as directed by a healthcare provider.
Choice D, Do not elevate the arm above the level of the heart, is not the correct answer because there is no restriction on elevating the arm above the level of the heart with a PICC line.

First-degree heart block is a type of atrioventricular (AV) block that involves the consistent prolongation of the PR interval (defined as >0.20 seconds) due to delayed conduction via the atrioventricular node.
This is seen on an ECG as a PR interval greater than 200 ms in length.
Choice B: Nondiscernible P waves are not an answer because it is not mentioned as a characteristic of first-degree heart block in my sources.
Choice C: More P waves than QRS complexes is not an answer because it is not mentioned as a characteristic of first-degree heart block in my sources.
Choice D: No correlation between P and QRS waves is not an answer because it is not mentioned as a characteristic of first-degree heart block in my sources.
Correct Answer is C
Explanation
“Weight loss of.8 kg (4 Ib) in the past 24 hr.” Furosemide is a diuretic that decreases the pressure caused by excess fluid in the heart and lungs.
A weight loss of.8 kg (4 Ib) in the past 24 hr indicates that excess fluid is being removed from the body, which is a sign that the medication is effective.
Choice A is incorrect because adventitious breath sounds are a symptom of pulmonary edema, not an indication that the medication is effective.
Choice B is incorrect because furosemide has direct vasodilatory outcomes 2, which would decrease blood pressure, not elevate it.
Choice D is incorrect because there is no information found to support this statement.
