A nurse who is caring for a preschooler should question a prescription for which of the following antibiotics?

A. Urinary retention: While urinary retention can be a side effect of meperidine and other opioids, it is not the priority assessment before administering the medication. Urinary retention is a concern but is not immediately life-threatening compared to other potential side effects of opioids, such as respiratory depression. Assessing urinary retention is important, but it is not the primary concern in this situation.

B. Vomiting: Vomiting can also be a side effect of opioids, including meperidine. While it is essential to assess for vomiting and its potential impact on the client's overall condition, it is not the priority assessment before administering the medication. Vomiting can be managed, and the nurse should address it as needed. However, the priority assessment is one that can affect the client's immediate safety and well-being, such as respiratory rate and potential respiratory depression.

C. Respiratory rate: This is the correct answer. The priority assessment before administering meperidine is the client's respiratory rate. Opioids can cause respiratory depression, leading to reduced breathing and inadequate ventilation. Monitoring the respiratory rate allows the nurse to detect any signs of respiratory distress or inadequate breathing, enabling them to intervene promptly to prevent serious complications.

D. Level of consciousness: While assessing the client's level of consciousness is essential for overall assessment and monitoring, it is not the priority assessment before administering meperidine. Respiratory depression due to opioid use can occur even when the client is conscious. However, if respiratory depression occurs, it can lead to a decrease in consciousness and potentially unconsciousness, making the assessment of respiratory rate more critical to prevent such complications.

The nurse should include tinnitus (ringing in the ears) as an adverse effect of gentamicin in the client's teaching. Gentamicin is an aminoglycoside antibiotic commonly used to treat bacterial infections. One of the potential side effects of gentamicin is damage to the inner ear, which can lead to tinnitus.

Tinnitus is a concerning symptom as it may indicate ototoxicity, which is damage to the structures of the inner ear responsible for hearing and balance. If the client experiences tinnitus while taking gentamicin, it is essential to notify the healthcare provider immediately to assess the severity of the issue and consider appropriate interventions.

Let's go through the other options and explain why they are not adverse effects of gentamicin:

A. Urinary frequency: Urinary frequency is not a common adverse effect of gentamicin. Gentamicin primarily affects the kidneys, and its main concern is related to potential nephrotoxicity (kidney damage) rather than causing urinary frequency.

B. Constipation: Constipation is not an adverse effect typically associated with gentamicin. Gentamicin is not known to affect the gastrointestinal system or cause constipation.

C. Hypertension: Hypertension (high blood pressure) is not a known adverse effect of gentamicin. Gentamicin primarily affects the kidneys and the inner ear, as mentioned earlier, but it does not significantly impact blood pressure.
