The client’s 24-hour urine output is 750 mL and an amber color, oral intake is 1700 mL, and the weight has increased 3 kilograms in 2 days.
The client is irritable and states “I have a headache.” Which laboratory value most correlates with these signs and symptoms?

Hemoglobin 15.3 mg/dL.

Serum Osmolality 265 mOsm/Kg.

Serum Sodium 134 mEq/L.

Urine specific gravity 1.025.

Answer and Explanation

The Correct Answer is B

This indicates that the client has a fluid volume deficit, which is consistent with the signs and symptoms of low urine output, weight gain, irritability, and headache. The normal range for serum osmolality is 275 to 295 mOsm/Kg.

Choice A is wrong because hemoglobin 15.3 mg/dL is within the normal range of 12 to 18 mg/dL and does not correlate with fluid imbalance.

Correct Answer is B

Explanation

Pulse oximetry works by measuring the amount of light that passes through your finger and reaches a sensor on the other side.

The amount of light that is absorbed by your blood depends on how much oxygen it carries. Nail polish can block or reflect some of the light, making it harder for the pulse oximeter to get an accurate reading of your oxygen level.

Choice A is wrong because the color of your nailbed is not relevant for pulse oximetry.

The pulse oximeter does not measure the color of your nailbed, but the amount of light that passes through it.

Choice C is wrong because the sensor does not react with the nail polish causing an allergic reaction.

The sensor is a non-invasive device that does not touch your skin or nail polish directly.

Choice D is wrong because the chemicals in the nail polish do not cause falsely decreased readings of your oxygen level.

The chemicals in the nail polish do not affect the amount of oxygen in your blood, but only the amount of light that reaches the sensor.

Normal ranges for pulse oximetry vary depending on your health condition and altitude, but generally they are between 95% and 100%. If your pulse oximetry reading is lower than 90%, you may have hypoxia, which means your tissues are not getting enough oxygen.

A. Place a stick in the person’s mouth to prevent biting of the tongue and call for assistance. B. Completely record time of the person’s seizure and save for paramedics. C. Restrain the limbs to prevent injury while providing as much privacy for the person as possible. D. Loosen the individual’s necktie after placing the person in the recovery position.

Correct Answer is D

Explanation

This is because the recovery position helps maintain the airway and prevent aspiration, and loosening the necktie prevents breathing restriction.

The other choices are wrong because:

Choice A is wrong because placing a stick or any object in the person’s mouth can cause injury to the teeth, gums, tongue or jaw and obstruct the airway. The person cannot swallow or bite their tongue during a seizure.

Choice B is wrong because recording the time of the seizure is not the first priority. The first priority is to ensure the safety and comfort of the person.

Choice C is wrong because restraining the limbs can cause injury or fracture, increase agitation and prolong the seizure. The nurse should protect the person from injury by moving furniture away and padding the head.

Normal ranges for seizure duration are usually less than 5 minutes for generalized tonic-clonic seizures and less than 15 seconds for absence seizures. If the seizure lasts longer than 5 minutes, or if the person has repeated seizures without regaining consciousness, it is considered a medical emergency and requires immediate treatment.
