A nurse is reviewing the laboratory results of a client and finds both their iron and vitamin B12 levels are below the expected reference range. The nurse should monitor the client for which of the following conditions?

A) "I do not need to sign a consent form before this procedure": This statement is incorrect. Most procedures involving intravenous (IV) dye or contrast require the client to sign a consent form. This is because the procedure involves the use of a contrast agent that could have potential risks or side effects, and the client needs to be informed and give consent for its use.

B) "I will feel a warming sensation after the injection of the dye": This statement is correct. It is common for patients to experience a warming or flushing sensation after the injection of IV contrast dye. This feeling is typically temporary and a normal response to the dye being introduced into the bloodstream. The nurse should reassure the client about this sensation.

C) "I should limit my fluid intake for 2 days after the procedure": This statement is incorrect. In most cases, clients are encouraged to increase their fluid intake after procedures involving IV contrast to help flush the dye from their system and prevent any potential kidney complications. Limiting fluid intake is generally not recommended unless otherwise instructed by the healthcare provider.

D) "I can have a meal up to 2 hours before the procedure": This statement is incorrect in many cases, especially if the procedure involves sedation or anesthesia. Typically, clients are instructed to fast for a period (usually 4–6 hours) before procedures involving contrast dye, particularly if anesthesia or sedation is used. Eating too soon before the procedure can increase the risk of aspiration or other complications. It’s important to follow specific instructions from the healthcare provider.

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.
