- A. Severe hypertension
- B. Drowsiness
- C. Nervousness
- D. Nausea

A patient is ordered to receive neomycin as part of the treatment plan for hepatic coma. Which of the following would be most important for the nurse to assess before administering this drug? Select all that apply.
- A. Ability to swallow
- B. Level of consciousness
- C. Baseline vital signs
- D. Pulmonary function
Correct Answer: A, B
Rationale: During the early stages of hepatic coma, various changes in the level of consciousness may be seen. At times, the patient may appear lethargic and respond poorly to commands. Because of these changes in the level of consciousness, the patient may have difficulty swallowing, and a danger of aspiration is present. If the patient appears to have difficulty taking an oral drug, the nurse should withhold the drug and contact the primary health care provider. Baseline vital signs are important but are not the priority when the patient has hepatic coma. The drug does not affect the patient's respiratory function. There is no infection; therefore, there is no need for culture and sensitivity testing.
A nurse is preparing to administer an aminoglycoside to a client. The nurse would be alert for the development of which of the following toxicities? Select all that apply.
- A. Nephrotoxicity
- B. Cardiotoxicity
- C. Ototoxicity
- D. Hepatotoxicity
Correct Answer: A, C, E
Rationale: More serious adverse reactions of aminoglycosides include nephrotoxicity, ototoxicity, and neurotoxicity. A nurse recognizing these can greatly reduce permanent damage to the client's hearing, kidneys, and nerves. Aminoglycosides are not associated with cardiotoxicity or hepatotoxicity.
A patient is receiving telithromycin. Based on the nurse's understanding of potential adverse reactions, the nurse would identify which nursing diagnosis as a priority?
- A. Ineffective Renal Tissue Perfusion
- B. Risk for Injury
- C. Diarrhea
- D. Risk for Impaired Skin Integrity
Correct Answer: B
Rationale: Telithromycin can cause visual disturbances such as difficulty focusing and accommodating to light. Therefore, the priority nursing diagnosis would be Risk for Injury related to these visual disturbances. Aminoglycosides can cause nephrotoxicity, leading to a nursing diagnosis of Ineffective Renal Perfusion. Although diarrhea and skin rashes can occur, these would not be a priority at this time.
