A client who is hypotensive is receiving dopamine, an adrenergic agonist, intravenously (IV) at the rate of 8 mg/kg/min.
Which intervention should the nurse implement while administering this medication?

Initiate seizure precautions.

Assess pupillary response to light hourly.

Measure urinary output every hour.

Monitor serum potassium frequently.

Answer and Explanation

The Correct Answer is C

Choice A rationale

While seizure precautions are important for clients receiving certain medications or with certain conditions, they are not typically necessary for clients receiving dopamine. Dopamine, an adrenergic agonist, does not typically increase the risk of seizures.

Choice B rationale

Assessing pupillary response to light hourly is not typically necessary for clients receiving dopamine. Dopamine does not typically affect pupillary response.

Choice C rationale

Measuring urinary output every hour is an important intervention for a client receiving dopamine. Dopamine at low to moderate doses can dilate renal blood vessels, which can increase urine output. Therefore, monitoring urinary output can help assess the effectiveness of the medication and the client’s renal perfusion.

Choice D rationale

While it is important to monitor electrolyte levels in clients receiving certain medications, frequent monitoring of serum potassium is not typically necessary for clients receiving dopamine. Dopamine does not typically affect serum potassium levels.

Correct Answer is B

Explanation

Choice A rationale
Gastric lavage is a procedure that involves the insertion of a tube into the stomach to remove its contents and is typically used in cases of poisoning or drug overdose. However, it should not be the first action taken. The type of chemical exposure needs to be determined first to guide appropriate treatment.
Choice B rationale
Determining the type of chemical exposure is crucial as it guides the subsequent steps in management. Different chemicals can have different effects on the body and require different treatments.
Choice C rationale
While assessing for altered sensorium is important in a child exposed to chemicals, it is not the first action. The nurse needs to identify the type of chemical the child was exposed to in order to anticipate potential complications and guide treatment.
Choice D rationale

Calling the poison control emergency number is an important step in managing a case of chemical exposure. However, having information about the type of chemical the child was exposed to can make this call more effective.

A. Avoid administering oxygen at high levels for extended periods. B. Increase the oxygen rate during sleep to compensate for a slower respiratory rate. C. Taking a sedative at bedtime slows the respiratory rate, which decreases oxygen needs. D. Oxygen is less toxic when it is humidified with a hydration source.

Correct Answer is A

Explanation

Choice A rationale
Oxygen therapy is a crucial part of the management for patients with severe pneumonia. However, prolonged administration of high concentrations of oxygen can potentially lead to oxygen toxicity, resulting in damage to the cells of the lungs. This is due to the production of

reactive oxygen species which can damage cell structures. Therefore, it is important to avoid administering oxygen at high levels for extended periods.
Choice B rationale
While it might seem logical to increase the oxygen rate during sleep due to a slower respiratory rate, this is not typically recommended. The body’s oxygen requirements do not significantly change during sleep and increasing the oxygen rate could potentially lead to hyperoxia.
Choice C rationale
Sedatives can indeed slow the respiratory rate, but this does not decrease oxygen needs. In fact, it could potentially lead to respiratory depression and hypoxia, especially in a patient with a respiratory illness like pneumonia.
Choice D rationale
Humidification of oxygen can improve patient comfort, especially with high flow rates, by preventing dryness in the nasal passages. However, it does not make oxygen less toxic.
