A nurse is teaching about food choices to a client who has chronic kidney disease and must limit potassium intake.
Which of the following choices should the nurse recommend as containing the least potassium?
1/2 cup nonfat yogurt.
1 medium baked potato with skin.
2 tbsp peanut butter.
1 cup white rice.
The Correct Answer is D

White rice is a low-potassium food that can be recommended for a client who has chronic kidney disease and must limit potassium intake.
Nonfat yogurt (choice A) contains moderate amounts of potassium and may not be the best choice for someone who needs to limit their potassium intake.
A medium baked potato with skin (choice B) is high in potassium and should be limited to a low-potassium diet.
Peanut butter (choice C) also contains moderate amounts of potassium and may not be the best choice for someone who needs to limit their potassium intake.

Lithium. Lithium is a medication that has been associated with an increased risk of developing diabetes insipidus. This is because lithium can interfere with the function of the kidneys and their ability to respond to antidiuretic hormone (ADH), which regulates the balance of fluids in the body.
Atorvastatin (choice B) is a medication used to lower cholesterol levels and has not been associated with an increased risk of diabetes insipidus.
Propranolol (choice A) is a beta-blocker used to treat high blood pressure and heart conditions and has not been associated with an increased risk of diabetes insipidus.
Ranitidine (choice C) is a medication used to reduce stomach acid production and has not been associated with an increased risk of diabetes insipidus.

Explanation

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.
