Question 1 of 5
An adult client has pulmonary tuberculosis. He is receiving isoniazid (INH) 300 mg PO, ethambutol 1 g PO daily, and streptomycin 1 g IM three times a week. When he comes in for a checkup, he tells the nurse that he hates getting shots and his ears ring most of the time. What is the best interpretation for the nurse to make regarding the client's complaints?
Correct Answer: B
Rationale: Streptomycin is ototoxic, and ringing in the ears (tinnitus) is a sign of potential eighth cranial nerve damage, requiring evaluation.
Question 2 of 5
An adult woman has been diagnosed as having hypothyroidism. She is taking Cytomel (liothyronine sodium) 50 mcg daily. Which of the following side effects should the nurse be especially alert for?
Correct Answer: A
Rationale: Cytomel increases metabolic rate, potentially causing angina in patients with cardiovascular risk due to increased cardiac demand.
Question 3 of 5
A client has bilateral knee pain from osteoarthritis. In addition to taking the prescribed non-steroidal anti-inflammatory drug (NSAID), the nurse should instruct the client to
Correct Answer: A
Rationale: start a regular exercise program. A regular exercise program is beneficial in treating osteoarthritis. It can restore self-esteem and improve physical functioning.
Question 4 of 5
The nurse practicing in a long term care facility recognizes that elderly clients are at greater risk for drug toxicity than younger adults because of which of the following physiological changes of advancing age?
Correct Answer: B
Rationale: Elders have less body water and more fat. Because elderly persons have decreased lean body tissue/water in which to distribute medications, more drug remains in the circulatory system with potential for drug toxicity. Increased body fat results in greater amounts of fat-soluble drugs being absorbed, leaving less in circulation, thus increasing the duration of action of the drug.
Question 5 of 5
A client has been receiving dexamethasone (Decadron) for control of cerebral edema. Which of the following assessments would indicate that the treatment is effective?
Correct Answer: B
Rationale: Decadron is a corticosteroid that acts on the cell membrane to decrease inflammatory responses as well as stabilize the blood-brain barrier. Once Decadron reaches a therapeutic level, there should be a decrease in symptomatology with improvement in motor skills.
