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 {"dropdown-group-1":"A","dropdown-group-2":"C"}

Explanation

Myasthenia Gravis

Myasthenia Gravis (MG) is an autoimmune disorder characterized by weakness and rapid fatigue of voluntary muscles. Key features include fluctuating muscle weakness that typically worsens with activity and improves with rest, bilateral ptosis (drooping of the eyelids), and difficulty with swallowing and speaking. The fact that the client's facial muscle strength is better in the morning and worsens throughout the day is a hallmark of MG. The edrophonium (Tensilon) test is specifically used to diagnose MG by temporarily improving muscle strength.

Antibodies at the neuromuscular junction

Myasthenia Gravis is caused by the presence of autoantibodies that target acetylcholine receptors at the neuromuscular junction, leading to impaired communication between nerves and muscles. This is consistent with the described symptoms and the use of the edrophonium (Tensilon) test to diagnose the condition.

A. Furosemide B. Albuterol C. Gentamicin D. Aspirin

Correct Answer is D

Explanation

A. Furosemide is a loop diuretic used to manage conditions such as hypertension and fluid retention. While furosemide has potential side effects, it is not specifically associated with an increased risk of developing cataracts.
B. Albuterol is a bronchodilator used to treat conditions such as asthma and chronic obstructive pulmonary disease (COPD). It is not associated with an increased risk of cataracts. Albuterol primarily affects the respiratory system and does not have a known link to cataract development.
C. Gentamicin is an antibiotic used to treat various bacterial infections. While gentamicin can have adverse effects on hearing and kidneys, it is not specifically associated with an increased risk of cataracts. Antibiotics like gentamicin do not have a well-established link to cataract development.

D. Aspirin is a nonsteroidal anti-inflammatory drug (NSAID) commonly used for pain relief, anti- inflammatory purposes, and cardiovascular protection. Long-term use of high doses of aspirin or other NSAIDs has been associated with various eye issues, including cataract formation.
