A patient is to receive a beta agonist. Before administration of this medication, which assessment finding would most concern the nurse?

Pulse oximetry reading of 95%

Respiratory rate of 22 breaths per minute

Blood pressure of 100/60 mm Hg

Heart rate of 120 beats/min

Answer and Explanation

The Correct Answer is D

Choice A reason: Pulse oximetry of 95% is near normal and not a major concern for beta agonist administration. Tachycardia is more critical due to cardiac stimulation, so this is incorrect.

Choice B reason: A respiratory rate of 22 is slightly elevated but acceptable in respiratory conditions. Beta agonists target airways, but tachycardia is a greater risk, making this incorrect.

Choice C reason: Blood pressure of 100/60 mm Hg is low, but beta agonists primarily affect heart rate. A pre-existing tachycardia is more concerning contraindication, so this is incorrect.

Choice D reason: A heart rate of 120 beats/min is concerning, as beta agonists increase heart rate, risking arrhythmias. This requires evaluation before administration, making it the correct concern.

Correct Answer is C

Explanation

Choice A reason: Uncompensated respiratory alkalosis requires low PaCO2 (<35 mm Hg) and high pH (>7.45). Here, PaCO2 is 48 mm Hg (high) and HCO3- is 29 mEq/L (high), indicating a metabolic cause with respiratory compensation, making this choice incorrect.

Choice B reason: Partially compensated respiratory alkalosis involves low PaCO2 and high HCO3- with high pH. With PaCO2 at 48 mm Hg (high) and HCO3- at 29 mEq/L, the alkalosis is metabolic, with elevated PaCO2 as compensation, making this choice incorrect.

Choice C reason: pH 7.48 (alkalotic), PaCO2 48 mm Hg (high), and HCO3- 29 mEq/L (high) indicate metabolic alkalosis (high HCO3-), with elevated PaCO2 showing partial respiratory compensation (hypoventilation to retain CO2). This matches partially compensated metabolic alkalosis, making it the correct choice.

Choice D reason: Uncompensated metabolic alkalosis requires high pH and high HCO3- with normal PaCO2. Here, PaCO2 is 48 mm Hg (high), indicating respiratory compensation, not an uncompensated state. This makes the condition partially compensated, so this choice is less accurate than C.

A. In the morning and at 4:00 PM B. Approximately 15 to 30 minutes before each meal C. After meals and at bedtime D. Once daily at bedtime

Correct Answer is D

Explanation

Choice A reason: Insulin glargine is a long-acting insulin given once daily, not twice daily. Morning and 4:00 PM dosing is typical for intermediate-acting insulins, so this incorrect for glargine’s schedule.

Choice B reason: Rapid-acting insulins are given before meals, not glargine, which provides basal coverage. Glargine is dosed once daily, so this is incorrect.

Choice C reason: Post-meal or after meals and bedtime dosing does not suit glargine’s 24-hour action. It’s given once daily, typically at bedtime, so this is incorrect for the administration timing.

Choice D reason: Insulin glargine is administered once daily, often at bedtime, to provide steady basal insulin coverage for 24 hours. This aligns with its pharmacokinetics, making it the correct choice.
