A nurse is assessing a client who has chronic kidney disease and notes that the client has small crystals on his forehead. The nurse understands that this manifestation is a result of an excess of which substance in the body?

Potassium

Sodium

Urea

Creatinine

Answer and Explanation

The Correct Answer is C

A.   Elevated potassium levels (hyperkalemia) can occur in chronic kidney disease, as the kidneys struggle to excrete potassium. However, hyperkalemia does not typically cause visible crystals on the skin. It is more associated with cardiac arrhythmias and muscle weakness rather than skin manifestations.
B.   Sodium imbalance is common in chronic kidney disease, often leading to fluid retention and hypertension. However, excess sodium does not result in crystal formation on the skin. Sodium issues are more related to fluid balance and blood pressure, not external crystalline deposits.
C.   Urea is a waste product formed from the breakdown of proteins and is normally excreted by the kidneys. In chronic kidney disease, urea accumulates in the blood (uremia) because the kidneys cannot effectively filter it out. Urea can be deposited on the skin and form crystals, leading to a condition known as "uremic frost." This is often observed on the forehead or other areas of the skin and is a direct result of excess urea in the body.

D.   Creatinine is another waste product filtered by the kidneys. Elevated levels indicate impaired kidney function, but creatinine itself does not form visible crystals on the skin. Elevated creatinine levels are primarily used as an indicator of kidney function rather than a cause of external skin manifestations.

Correct Answer is C

Explanation

A. Raw vegetables can be challenging for individuals with myasthenia gravis because they require significant chewing and can lead to fatigue of the jaw muscles. Additionally, raw vegetables can be difficult to swallow if there is significant weakness.
B. Granola bars can be hard and require extensive chewing. For a person with myasthenia gravis, the effort needed to chew and swallow these bars can lead to increased fatigue and difficulty managing meals.
C. Macaroni and cheese is a softer food that requires less chewing compared to raw vegetables or granola bars. It can be easier for individuals with myasthenia gravis to manage because it is soft and less likely to cause fatigue. Additionally, it can be enriched with nutrients and is easier to swallow, making it a more appropriate choice for a nutritional plan for someone with MG.
D. Dried fruit is typically tough and chewy, which can be difficult for someone with myasthenia gravis to handle. The chewing effort required can lead to muscle fatigue and discomfort.

Correct Answer is ["50"]

Explanation

Flow rate in gtt/min = (Volume in mL * Drop factor) / Time in minutes.
The prescribed volume is 150 mL/hr. Since there are 60 minutes in an hour, the time for one hour would be 60 minutes. The drop factor is 20 gtt/mL.
(150 mL/hr * 20 gtt/mL) / 60 min/hr = 3000 gtt/hr / 60 min/hr = 50 gtt/min.
Therefore, the nurse should set the manual IV infusion to deliver 50 gtt/min.
