A nurse is providing teaching for a client who has a prescription for gentamicin. Which of the following should the nurse include as an adverse effect of this medication?
Urinary frequency
Constipation
Hypertension
Tinnitus
The Correct Answer is D
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.

Correct Answer is B
Explanation
When caring for a client receiving a continuous infusion of total parenteral nutrition (TPN), the nurse should implement the intervention of checking the client's blood glucose level regularly. TPN is a highly concentrated intravenous nutrition solution containing glucose, amino acids, lipids, vitamins, and minerals, and it is used to provide complete nutrition when the client cannot take oral nutrition.
Monitoring blood glucose levels regularly is essential because TPN is rich in glucose, which can significantly affect the client's blood sugar levels. Hyperglycemia (high blood sugar) is a potential complication of TPN infusion. Regular blood glucose monitoring allows the nurse to detect and address any changes in blood sugar levels promptly and to adjust the TPN infusion rate or administer insulin, if necessary, to maintain the client's blood sugar within the target range.
Let's go through the other options:
A. Change the TPN infusion tubing once every 3 days: While changing the TPN infusion tubing regularly is a good practice to maintain asepsis and prevent infection, it is not the priority intervention in this situation. Regularly checking the client's blood glucose level is more crucial to monitor the effects of TPN on blood sugar levels.
C. Insert the peripheral IV catheter for administration: Total parenteral nutrition is a hypertonic solution that can cause irritation and damage to peripheral veins. It is usually administered through a central venous catheter (CVC) placed in a large vein, such as the subclavian or jugular vein. Inserting a peripheral IV catheter for TPN administration is not recommended due to the risk of vein damage and thrombosis.
D. Monitor the client's weight every 3 days: Monitoring the client's weight is an important part of assessing their nutritional status and fluid balance. However, the priority intervention for a client receiving TPN is checking their blood glucose level regularly, as hyperglycemia is a common and significant concern in TPN administration.
Correct Answer is ["0.12 mL\/hr"]
Explanation
To calculate the rate at which the IV pump should be set to deliver dopamine, we need to determine the total amount of dopamine in the infusion and divide it by the desired dose per minute.
Given:
Dopamine concentration: 400 mg in 250 mL
Desired dose: 5 mcg/kg/min
Patient weight: 220 lb
First, we need to convert the patient's weight from pounds to kilograms:
220 lb ÷ 2.2 = 100 kg
Next, we need to calculate the total amount of dopamine needed per minute:
5 mcg/kg/min × 100 kg = 500 mcg/min
Now, we need to convert the dopamine dose from mcg to mg:
500 mcg/min ÷ 1000 = 0.5 mg/min
To determine the infusion rate in mL/hr, we divide the dose in mg/min by the dopamine concentration in the infusion solution:
0.5 mg/min ÷ 250 mL = 0.002 mL/min
Finally, we convert the infusion rate from mL/min to mL/hr by multiplying by 60:
0.002 mL/min × 60 min = 0.12 mL/hr
Therefore, the nurse should set the IV pump to deliver 0.12 mL/hr.
