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
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 B
Explanation
a. Overusing a muscle while jogging: Overuse injuries are more commonly associated with strains, not sprains. Strains involve the muscles or tendons.
b. Twisting a ligament while walking: This is an example of a mechanism that can lead to a sprain. A sprain involves the stretching or tearing of ligaments, which connect bone to bone.
c. Impact injury on a joint from a fall: This is more likely to result in a sprain, as it can cause damage to ligaments.
d. Crush injury to a bone from blunt trauma: This type of injury is more likely to affect bones rather than ligaments or tendons, and it would not be considered a sprain or strain.
Correct Answer is D
Explanation
A. “I will notify my provider before taking any other medications.” - This statement reflects an understanding of the need to check for potential interactions with other medications, which is an appropriate response.
B. “I have made an appointment to see my dentist next week.” - Dental care is important, and
scheduling an appointment with the dentist is a responsible action. However, it does not indicate a misunderstanding about the medication.
C. “I will take this medication with meals.” - Taking phenytoin with meals is a correct instruction as it can help reduce gastrointestinal side effects.
D. "I'll be glad when my seizures stop so I can quit taking this medicine." - This statement
indicates a misunderstanding about the chronic nature of anti-seizure medications. The client needs further education on the importance of continuing the medication even if seizures stop.
