Respiratory alkalosis

Metabolic alkalosis

Metabolic acidosis

Respiratory acidosis

Answer and Explanation

The Correct Answer is C

A nurse reviewing the laboratory results of a client who has DKA should identify that the client's ABG results of pH 7.30, PaCO₂ 34 mm Hg and HCO₃ 21 mEq/L indicate metabolic acidosis. Metabolic acidosis is an acid-base imbalance characterized by a low pH (less than 7.35) and a low bicarbonate level (less than 22 mEq/L).

The other options are not correct.

a) Respiratory alkalosis is an acid-base imbalance characterized by a high pH (greater than 7.45) and a low PaCO₂ (less than 35 mm Hg).

b) Metabolic alkalosis is an acid-base imbalance characterized by a high pH (greater than 7.45) and a high bicarbonate level (greater than 26 mEq/L).

d) Respiratory acidosis is an acid-base imbalance characterized by a low pH (less than 7.35) and a high PaCO₂ (greater than 45 mm Hg).

Correct Answer is D

Explanation

The nurse should expect to find hyperkalemia in the medical record of a client who has sustained a full- thickness burn and is in the emergent phase of the burn. This is due to the release of potassium from damaged cells into the bloodstream.

a) Hypernatremia is not a common finding in the emergent phase of a burn.

b) Hypercalcemia is not a common finding in the emergent phase of a burn.

c) Hypermagnesemia is not a common finding in the emergent phase of a burn.

A. Constipation: Constipation is not a common or significant side effect of cefazolin. While antibiotics can sometimes cause gastrointestinal disturbances such as diarrhea or nausea, constipation is unlikely to be a major concern for this medication. The adolescent should be encouraged to maintain hydration and a balanced diet, but constipation is not a priority symptom to report in this case. B. Elevated skin patches: Elevated skin patches or rashes could be a sign of an allergic reaction to cefazolin, but this is not the most immediate or critical symptom to monitor for in the context of the question. If an allergic rash develops, the adolescent should certainly report it, but elevated skin patches are more general and not directly associated with a serious or common side effect of cefazolin. Immediate concerns would be other signs of an allergic reaction, such as swelling or difficulty breathing. C. Ringing in the ears: Ringing in the ears (tinnitus) can be a sign of ototoxicity, a known side effect of cefazolin, especially when administered in high doses or for prolonged periods. Ototoxicity can affect hearing and balance, and tinnitus is an early symptom. This is a serious issue that should be reported immediately, as the drug might need to be adjusted or discontinued to prevent permanent damage to the ears. D. Depression: While depression is a serious condition that can affect adolescents, it is not a known side effect of cefazolin. If an adolescent experiences mood changes or symptoms of depression, these should be addressed, but they are unlikely to be directly related to the medication. Depression should always be taken seriously and managed, but it is not a primary concern related to cefazolin use.

Correct Answer is C

Explanation

c. Ringing in the ears.

Explanation:

Cefazolin is an antibiotic medication that belongs to the class of cephalosporins. While it is generally safe and well-tolerated, it can have potential side eﬀects that should be monitored and reported to the healthcare provider. One of the potential side eﬀects of cefazolin is ototoxicity, which can manifest as ringing in the ears (tinnitus) or other hearing disturbances. If the adolescent experiences any ringing in the ears or changes in hearing while taking cefazolin, it should be reported to the healthcare provider for further evaluation.

Options a, b, and d are not specifically associated with the use of cefazolin. Constipation can occur due to various reasons unrelated to this medication. Elevated skin patches may be indicative of an allergic reaction or other skin condition but are not specific to cefazolin. Depression is not a common side eﬀect of cefazolin and should be evaluated separately if experienced by the adolescent.
