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. Low BP and low pulse rate: In hypovolemic shock, there is a decrease in blood volume,
leading to low blood pressure. However, the body compensates by increasing the heart rate to maintain perfusion to vital organs.
b. Low BP and high pulse rate: This is indicative of hypovolemic shock. The low blood pressure results from decreased blood volume, while the high pulse rate is a compensatory mechanism to maintain cardiac output.
c. High BP and low pulse rate: This combination is not typical of hypovolemic shock. High blood pressure is not expected in the presence of decreased blood volume.
d. High BP and high pulse rate: While a high pulse rate is expected in hypovolemic shock, high blood pressure is not a characteristic finding.
Correct Answer is A
Explanation
a. Bradycardia: Atenolol is a beta-blocker that can slow down the heart rate, leading to
bradycardia. Monitoring the client for signs of bradycardia, such as dizziness, fatigue, or fainting, is important.
b. Anemia: Atenolol is not known to cause anemia. Monitoring for anemia is not a specific concern with this medication.
c. Hypokalemia: Atenolol is not associated with causing hypokalemia. However, beta-blockers in general may affect potassium levels indirectly.
d. Neutropenia: Atenolol is not typically associated with causing neutropenia. Monitoring for neutropenia is not a specific concern with this medication.
