The nurse is monitoring a client receiving gentamicin.
Which of the following would the nurse assess as potential toxic effects of this medication?
Pseudomembranous colitis and crystalluria.
Headaches, vertigo, and tinnitus.
Headache and potassium 3.5 mg/dL.
Hypoglycemia and cardiac dysrhythmias.
The Correct Answer is B
Choice A rationale
Pseudomembranous colitis and crystalluria are not typically associated with gentamicin use.
Choice B rationale
Gentamicin can cause ototoxicity, which can manifest as tinnitus (ringing in the ears), vertigo (a sensation of spinning), and hearing loss. Headaches can also occur as a side effect of gentamicin.
Choice C rationale
While gentamicin can cause nephrotoxicity (kidney damage), which could potentially affect electrolyte levels, a potassium level of 3.5 mg/dL is within the normal range. Therefore, this would not typically be assessed as a toxic effect of gentamicin.
Choice D rationale
Hypoglycemia and cardiac dysrhythmias are not typically associated with gentamicin use.

Correct Answer is C
Explanation
Choice A rationale
Injecting the insulin syringe at a 90-degree angle is a technique used to ensure that the insulin is delivered into the subcutaneous tissue. However, this does not specifically prevent lipodystrophy.
Choice B rationale
Avoiding the deltoid when injecting insulin is not typically a recommendation for preventing lipodystrophy. Insulin is usually injected into the fatty tissue just under the skin in the abdomen, thighs, buttocks, or upper arms.
Choice C rationale
Rotating injection sites correctly is a key strategy for preventing lipodystrophy. Lipodystrophy refers to abnormal changes in the fat tissue under the skin and can be caused by repeatedly injecting insulin into the same spot.
Choice D rationale
Massaging the injection site is not typically recommended as it can cause the insulin to be absorbed too quickly.
Correct Answer is C
Explanation
Choice A rationale
Omitted meals can lead to hypoglycemia, not diabetic ketoacidosis (DKA). DKA is caused by a lack of insulin, not a lack of food intake.
Choice B rationale
Polydipsia and polyphagia are symptoms of hyperglycemia, not causes of DKA. They occur as the body tries to compensate for high blood sugar levels.
Choice C rationale
Not taking enough insulin is a primary cause of the development of DKA. Without enough insulin, the body begins to break down fat for fuel, which produces acids known as ketones.
Choice D rationale
An insulin overdose would lead to hypoglycemia, not DKA. DKA is caused by a lack of insulin, not an excess.
