A nurse is collecting data from a client who has systemic lupus erythematosus (SLE). Which of the following laboratory values should the nurse review to determine the client's renalfunction?

C-reactive protein

Serum creatinine

Antinuclear antibody

Erythrocyte sedimentation rate

Answer and Explanation

The Correct Answer is B

a. C-reactive protein: This is a marker of inflammation and is not specific to renal function. It is more commonly used to assess inflammation in various conditions.

b. Serum creatinine: Elevated levels of serum creatinine are indicative of impaired renal

function. Creatinine is a waste product that is normally filtered by the kidneys. Increased levels suggest decreased renal filtration.

c. Antinuclear antibody: This test is used to diagnose autoimmune diseases like SLE but does not directly measure renal function.

d. Erythrocyte sedimentation rate: This is a nonspecific marker of inflammation and is not directly related to renal function.

Correct Answer is C

Explanation

a. Circular, erythematous patches on the scalp: This description is more indicative of tinea capitis, a fungal infection affecting the scalp.

b. Recent exposure to poison ivy: Poison ivy exposure would result in a contact dermatitis rash, not tinea pedis.

c. Scaling and redness between the toes: Tinea pedis, also known as athlete's foot, commonly presents with scaling, redness, and itching between the toes.

d. A recent prescription for an antiseizure medication: Antiseizure medications are not associated with the development of tinea pedis.

A. Decreased calcium level B. Decreased potassium level C. Elevated magnesium level D. Elevated sodium level

Correct Answer is B

Explanation

a. Decreased calcium level: NG tube drainage is more likely to result in hypokalemia (decreased potassium) than hypocalcemia (decreased calcium).

b. Decreased potassium level: NG tube drainage, which contains stomach contents, can lead to loss of potassium. Monitoring for hypokalemia is crucial as it can result in cardiac dysrhythmias.

c. Elevated magnesium level: NG tube drainage is not typically associated with an increase in magnesium levels.

d. Elevated sodium level: NG tube drainage may contribute to sodium loss, leading to hyponatremia, rather than hypernatremia.
