Which finding in a client diagnosed with obstructive sleep apnea (OSA) would require a nurse to take immediate action?
Client difficult to arouse.
Blood pressure 142/92 mmHg.
Apneic periods lasting more than 10 seconds.
Oxygen desaturation to 90% when asleep.
The Correct Answer is A
This is because a client with obstructive sleep apnea (OSA) may have periods of apnea lasting more than 10 seconds during sleep, which can lead to hypoxia and hypercapnia. These conditions can cause the client to be difficult to arouse and may indicate respiratory failure.
The nurse should take immediate action to stimulate the client, provide oxygen, and call for help.
Choice B is wrong because blood pressure 142/92 mmHg is not an emergency for a client with OSA. It is within the stage 1 hypertension range, which may be caused by OSA or other factors. The nurse should monitor the client’s blood pressure and encourage lifestyle modifications, such as weight loss, exercise, and dietary changes.
Choice C is wrong because apneic periods lasting more than 10 seconds are expected in a client with OSA. This is the criterion for diagnosing OSA during a sleep study. The nurse should educate the client about the use of continuous positive airway pressure (CPAP) or other treatments to prevent apnea and improve oxygenation during sleep.
Choice D is wrong because oxygen desaturation to 90% when asleep is not an emergency for a client with OSA. It is a common finding in OSA due to the intermittent obstruction of the upper airway. The nurse should ensure that the client has supplemental oxygen available and teach the client about the benefits of CPAP or other devices to maintain airway patency and oxygen saturation during sleep.

Correct Answer is B
Explanation
To find the rate of the pump in ml/hour, you need to first convert the client’s weight from pounds to kilograms. You can do this by dividing the weight by 2.2046 or multiplying it by 0.454.
For example:
297 lbs / 2.2046 = 134.72 kg or 297 lbs x 0.454 = 134.72 kg
Then, you need to multiply the client’s weight in kilograms by the ordered dose in units/kg/hour to get the total units per hour.
For example:
134.72 kg x 12 units/kg/hour = 1616.64 units/hour
Next, you need to set up a proportion to find the rate of the pump in ml/hour using the supplied medication concentration.
For example:
25,000 units / 500 ml = 1616.64 units / X ml Cross-multiply and solve for X:
25,000 x X = 808320 X = 808320 / 25000 X = 32.33 ml/hour
Finally, you need to round your answer to the nearest tenth of a ml/hour as per the medication administration guidelines.
For example:
32.33 ml/hour ≈ 32.3 ml/hour
Therefore, the rate of the pump is 32.3 ml/hour.
Choice A is wrong because it uses a different conversion factor for pounds to kilograms (1 lb = 0.5 kg) which is not accurate.
Choice C is wrong because it uses a different ordered dose (10 units/kg/hour) which is not what the provider has written.
Choice D is wrong because it uses a different supplied medication concentration (20,000 units in 500 ml) which is not what is available.
Correct Answer is B
Explanation
Potassium is 3.0.
This is because furosemide is a loop diuretic that can cause hypokalemia (low potassium levels) as a side effect. Hypokalemia can lead to muscle weakness, cramps, cardiac arrhythmias, and digoxin toxicity. The normal range for potassium is 3.5 to 5.0 mEq/L.
Choice A is wrong because sodium is 144 is within the normal range of 135 to 145 mEq/L.
Choice C is wrong because chloride is 99 is within the normal range of 98 to 106 mEq/L.
Choice D is wrong because calcium is 5.0 is within the normal range of 4.5 to 5.5 mg/dL.
