A nurse is reviewing the medical record of a client who is taking acetaminophen to relieve headache pain.

Which of the following conditions in the client's history should the nurse identify as a contraindication?

When a client is receiving gentamicin via IV infusion, it's essential to monitor for potential adverse effects. One of the well-known adverse effects of gentamicin is ototoxicity, which can manifest as hearing loss. Therefore, the nurse should identify the following manifestation as an adverse effect of the treatment:

B) New onset of hearing loss

Hypotension (option A), hyperthermia (option C), and slurred speech (option D) are not typically associated with gentamicin use and would be less likely to be related to the treatment. However, it's essential to assess the client for other side effects and monitor their overall condition while receiving gentamicin to ensure their safety and well-being.

The correct answer is D.

Chadwick's sign. Chadwick's sign is a bluish discoloration of the cervix, vagina, and vulva caused by increased blood flow to these areas during pregnancy. It usually appears around 6 to 8 weeks of gestation and persists until delivery. It is one of the presumptive signs of pregnancy, which are subjective changes that suggest pregnancy but are not conclusive. Ballottement is a technique of palpating the uterus to detect fetal movement when a finger is inserted into the vagina and tapped against the cervix. It can be performed between 16 and 28 weeks of gestation and is also a presumptive sign of pregnancy.

Chloasma is a condition characterized by brown patches on the face that may occur during pregnancy due to hormonal changes. It is also known as melasma or mask of pregnancy and usually fades after delivery. Hegar's sign is a softening of the lower uterine segment that can be felt during bimanual examination around 6 weeks of gestation. It is one of the probable signs of pregnancy, which are objective changes that strongly indicate pregnancy but are not diagnostic.
