A nurse is reinforcing teaching with a caregiver of a 2-month-old infant about developmentally appropriate toys. which of the following toys should the nurse include in the teaching?

A) Slurred speech:
Slurred speech is not a common adverse effect of gentamicin. It could indicate neurological issues, but it is not typically associated with gentamicin use. If this occurs, the nurse should investigate other possible causes, such as a stroke or another neurological condition, rather than attributing it to the gentamicin.

B) Constipation:
Constipation is not a typical adverse effect of gentamicin. While antibiotics can sometimes cause gastrointestinal disturbances, gentamicin is more commonly associated with nephrotoxicity and ototoxicity, rather than constipation. If constipation occurs, it is more likely related to other factors such as diet or fluid intake.

C) Hypotension:
While hypotension can be a side effect of many medications, it is not a specific or common adverse effect of gentamicin. Gentamicin is more likely to cause nephrotoxicity and ototoxicity rather than significant blood pressure changes. However, hypotension could occur in the context of an infection or severe illness and should be monitored, but it is not directly associated with gentamicin.

D) New onset of hearing loss:
This is a well-known adverse effect of gentamicin. Gentamicin belongs to the class of antibiotics known as aminoglycosides, which can cause ototoxicity. New onset of hearing loss or tinnitus (ringing in the ears) is a significant warning sign of ototoxicity, which can occur due to gentamicin use. This side effect should be monitored closely, and if hearing loss occurs, the medication should be reevaluated, and alternatives should be considered.

Yellowing of the eyes (Jaundice) → Isoniazid and Rifampin can cause hepatotoxicity, leading to jaundice.

Blurred vision → Ethambutol can cause optic neuritis, leading to blurred vision and color blindness.

Dry eyes (Incorrect) → Not a common side effect of TB medications.

Gastrointestinal:

Abdominal pain → Isoniazid, Rifampin, and Pyrazinamide are hepatotoxic and can cause liver inflammation and gastric irritation.

Weight gain (Incorrect) → TB medications are more likely to cause weight loss rather than gain.

Hematologic:

Increased bruising & bleeding tendencies → Rifampin can cause thrombocytopenia, increasing the risk of bruising and bleeding.

Insomnia (Incorrect) → Not a serious adverse effect of TB medications.

Genitourinary:

Darkening of the urine → Rifampin causes orange-red discoloration of urine, sweat, and tears, which is a benign but expected effect.

Urinary frequency (Incorrect) → Not a known adverse effect of TB medications.
