A client receives ondansetron prior to a chemotherapy treatment. How should the practical nurse evaluate the effectiveness of the medication?
Observe the client for signs of pain or discomfort during the treatment.
Assess for changes in vital signs during and after the treatment.
Monitor the client for nausea or vomiting following the treatment.
Determine if the client feels calm and relaxed before the treatment.
The Correct Answer is C
A. Observing for signs of pain or discomfort during the treatment is not a direct method for evaluating ondansetron’s effectiveness. Ondansetron is used to prevent nausea and vomiting, not to manage pain.
B. While assessing vital signs is important for overall monitoring, it does not specifically measure the effectiveness of ondansetron for preventing nausea and vomiting.
C. Monitoring for nausea or vomiting following the treatment is the most direct way to evaluate the effectiveness of ondansetron. The primary goal of ondansetron is to prevent or reduce these symptoms associated with chemotherapy.
D. Evaluating if the client feels calm and relaxed is not a measure of ondansetron’s effectiveness. The focus should be on the medication’s ability to prevent nausea and vomiting rather than the client's emotional state before treatment.

Correct Answer is ["A","B","C"]
Explanation
A. Heart rate 99 beats/minute
A heart rate of 99 beats/minute is slightly elevated. Tachycardia can be a sign of fluid volume deficit, as the body compensates for decreased blood volume and pressure by increasing heart rate to maintain adequate perfusion.
B. Dark, yellow urine
Dark yellow urine indicates concentrated urine, which is a sign of dehydration or fluid volume deficit. Proper hydration would typically result in light yellow urine.
C. Urinated 30 mL
A urine output of 30 mL is low, especially for an adult in a 1-hour period. Low urine output can be a sign of fluid volume deficit, as the kidneys may not be excreting enough urine due to inadequate fluid intake or retention.
D. Temperature 101° F (38.3° C)
An elevated temperature indicates a fever, which is related to the infection (pneumonia) rather than fluid volume status. It does not directly indicate a fluid volume deficit.
E. Client is awake and alert
Being awake and alert indicates that the client’s neurological status is stable and is not indicative of fluid volume deficit. It does not reflect the client’s fluid volume status.
F. Blood pressure 115/71 mm Hg
A blood pressure of 115/71 mm Hg is within normal limits. While fluid volume deficits can affect blood pressure, this finding alone does not indicate a deficit since the blood pressure is stable.
Correct Answer is B
Explanation
A. Isoniazid can cause side effects like peripheral neuropathy, but ringing in the ears is not a common symptom of this medication.
B. Gentamicin can cause ototoxicity, which includes symptoms such as ringing in the ears (tinnitus). This side effect is significant and should be reported to the healthcare provider for further evaluation.
C. Pyridoxine is used to prevent neuropathy caused by isoniazid and does not cause ringing in the ears.
D. Rifampin is an antitubercular medication but is not commonly associated with tinnitus as a side effect. The immediate concern with ringing in the ears is related to gentamicin.
