The nurse attaches a pulse oximeter to a client's finger and obtains an oxygen saturation reading of 91%. Which assessment finding most likely contributes to this reading?

Blood pressure is 142/88 mm Hg.

Radial pulse volume is 3+.

2+ edema of fingers and hands.

Capillary refill time is 2 seconds.

Answer and Explanation

The Correct Answer is C

A. Blood pressure is 142/88 mm Hg:

While elevated blood pressure may have implications for cardiovascular health, it is not directly related to oxygen saturation levels measured by a pulse oximeter.

B. Radial pulse volume is 3+:

A strong radial pulse volume suggests adequate peripheral perfusion, which would not typically contribute to a low oxygen saturation reading.

C. 2+ edema of fingers and hands:

Edema of the fingers and hands can impair the transmission of light through tissues, which may interfere with the accuracy of oxygen saturation readings obtained from a pulse oximeter. Edematous tissues may absorb light and lead to falsely low readings.

D. Capillary refill time is 2 seconds:

Normal capillary refill time indicates adequate peripheral circulation, which would not typically contribute to a low oxygen saturation reading.

Correct Answer is ["C","E"]

Explanation

A. Drink a mixture of warm water, whiskey, and honey at bedtime:

This suggestion is not appropriate as alcohol consumption close to bedtime can disrupt sleep patterns and exacerbate sleep problems. Additionally, alcohol can interact with medications and pose risks to health.

B. Ask the healthcare provider for a mild sedative for bedtime:

While medication may be prescribed for sleep disturbances in some cases, it should not be the first line of treatment, especially in older adults. Sedatives can have adverse effects and may lead to dependency if used long-term. Non-pharmacological interventions should be tried first.

C. Avoid drinking caffeinated beverages late in the day:

This is an appropriate suggestion. Caffeine is a stimulant that can interfere with sleep, so avoiding caffeinated beverages late in the day can help improve sleep quality.

D. Take an afternoon nap to make up for missed sleep:

While napping may be beneficial for some individuals, particularly if they are sleep deprived, it can worsen sleep difficulties in others, especially if taken late in the day. For individuals with insomnia or frequent nighttime awakenings, avoiding naps or limiting them to earlier in the day may be helpful.

E. Establish a regular time for going to bed and getting up:

This is an appropriate suggestion. Establishing a consistent sleep schedule helps regulate the body's internal clock and promotes better sleep quality. Going to bed and waking up at the same time each day, even on weekends, can help synchronize sleep-wake cycles and improve overall sleep patterns.

A. 1.035. B. 1.015. C. 1.005. D. 1.025. E. 1.025.

Correct Answer is A

Explanation

A. 1.035:

This specific gravity value indicates highly concentrated urine. In the context of a client experiencing vomiting, diarrhea, and difficulty tolerating oral fluids, such a high specific gravity would be indicative of significant dehydration. Dehydration occurs when the body loses more fluid than it takes in, leading to an imbalance in electrolytes and an increase in urine concentration.

B. 1.015:

This specific gravity value falls within the normal reference range for urine specific gravity. In the context of vomiting, diarrhea, and difficulty tolerating oral fluids, a value within the normal range may be less likely. However, it's important to note that initial testing may not reflect the full extent of dehydration, especially if the client's fluid intake has been severely limited over a short period.

C. 1.005:

This specific gravity value is at the lower end of the normal reference range for urine specific gravity. In a client experiencing significant fluid loss through vomiting and diarrhea, the urine may become more concentrated as the body attempts to conserve water. Therefore, a value of 1.005 would be less likely on initial testing in this context.

D. 1.025:

Similar to Option B, this specific gravity value falls within the normal reference range. While it's possible for a dehydrated individual to have a specific gravity within the normal range, a value of 1.025 may be less likely in the context of significant fluid loss through vomiting and diarrhea. However, it's important to consider that dehydration severity and urine concentration can vary among individuals.
