A client receives a prescription for ophthalmic ketorolac, Prior to administering the medication, the nurse should review the medical record for which condition?
Corneal abrasion
Radiation exposure
Foreign body
Chemical burn
The Correct Answer is A
A. A corneal abrasion is a condition that may be exacerbated by the use of ketorolac due to its potential to delay healing and increase bleeding risks. Therefore, it is essential to ensure that a patient does not have a corneal abrasion before administering ophthalmic ketorolac.
B. Radiation exposure is not directly relevant to the administration of ophthalmic ketorolac.
C. The presence of a foreign body is not directly related to ketorolac use
D. The presence of a chemical burn is not related with ketorolac use in a client.

Correct Answer is B
Explanation
B. pH 7.46, PCO2 55 mm Hg, HCO3 36 mEq/L, PO2 95 mm Hg
The pH is high (alkalotic).
The HCO3 level is elevated, indicating metabolic alkalosis.
The PCO2 is high (respiratory acidotic picture due to secondary response). This option matches the criteria for metabolic alkalosis.
A. pH 7.30, PCO2 20 mm Hg, HCO3 22 mEq/L, PO2 85 mm Hg
The pH is low (acidic), not alkalotic.
The HCO3 level is within the normal range.
The PCO2 is low, which could indicate respiratory alkalosis. This option does not match the criteria for metabolic alkalosis.
C. pH 7.49, PCO2 45 mm Hg, HCO3 32 mEq/L, PO2 90 mm Hg The pH is high (alkalotic).
The HCO3 level is elevated, indicating metabolic alkalosis. The PCO2 is within the normal range.
This option does not meet the criteria for metabolic alkalosis D pH 7.29, PCO2 35 mm Hg, HCO3 25 mEq/L, PO2 99 mm Hg
The pH is low (acidic), not alkalotic. The HCO3 level is low, not elevated. The PCO2 is within the normal range.
This option does not match the criteria for metabolic alkalosis.
Correct Answer is D
Explanation
D. Respiratory acidosis occurs when there is inadequate alveolar ventilation, leading to retention of carbon dioxide (hypercapnia) in the blood. The accumulation of carbon dioxide results in an increase in the partial pressure of carbon dioxide (PaCO2), leading to respiratory acidosis.
A. Hyperventilation refers to breathing at a rate and depth that exceeds the body's metabolic needs, leading to a decrease in the partial pressure of carbon dioxide (PaCO2) in the blood. Respiratory acidosis, however, is characterized by an increase in PaCO2 due to inadequate ventilation, not rapid elimination of carbon dioxide.
B. This choice refers to the hypoxic drive, which is a compensatory mechanism triggered by low oxygen levels in the blood. While hypoxemia (low oxygen levels) can stimulate the respiratory rate, it typically occurs in chronic respiratory conditions such as chronic obstructive pulmonary disease (COPD) rather than acute respiratory acidosis.
C. While the kidneys play a role in regulating acid-base balance through the excretion of hydrogen ions and reabsorption of bicarbonate ions, they do not directly eliminate carbon dioxide from the body.
