A client is scheduled for a “total serum cholesterol” lab test.
Which instruction to the client should be discussed to ensure adequate preparation for the test?

Do not eat or drink for 12 hours prior to the test.

Eliminate all dietary cholesterol for one week before this test.

Avoid caffeinated beverages for several days prior to the test.

Stop eating eggs and drinking milk for two days before the test.

Answer and Explanation

The Correct Answer is A

Do not eat or drink for 12 hours prior to the test. This is because fasting is required for a total serum cholesterol test to get accurate results. Fasting means not eating or drinking anything except water for 9 to 12 hours before the test.

Choice B is wrong because eliminating all dietary cholesterol for one week before the test is not necessary and will not affect the test results. Dietary cholesterol only accounts for a small portion of the total cholesterol in the blood.

Choice C is wrong because avoiding caffeinated beverages for several days prior to the test is not required and will not influence the test results. Caffeine does not affect cholesterol levels.

Choice D is wrong because stopping eating eggs and drinking milk for two days before the test is not needed and will not change the test results. Eggs and milk contain cholesterol, but they also have other nutrients that may lower the risk of heart disease.

Normal ranges for total serum cholesterol are less than 200 mg/dL (5.18 mmol/L) for adults. Higher levels may indicate an increased risk of heart disease and stroke.

Correct Answer is B

Explanation

“My medication will be given at the scheduled times to best manage my pain.” This statement demonstrates understanding of the pain management plan because it shows that the client knows the importance of preventing pain from becoming severe by taking medication regularly. Scheduled administration of analgesics is more effective than administering them on demand.

Choice A is wrong because it implies that the client will wait until the pain is severe before asking for medication, which can make it harder to control.

Choice C is wrong because it suggests that the client expects to receive inadequate pain relief due to their history of opioid abuse, which is not ethical or evidence-based.

Choice D is wrong because it indicates that the client believes they will be denied any narcotics for pain, which is also not ethical or

evidence-based. Clients with a history of opioid abuse can still receive opioids for acute pain, but they may need higher doses or more frequent administration to achieve adequate analgesia.

Normal ranges for vital signs are as follows: respiratory rate 12-20 breaths per minute, heart rate 60-100 beats per minute, blood pressure 120/80 mmHg, temperature 36.5-37.5°C (97.7- 99.5°F).

A. 26.7 ml/hour. B. 28.3 ml/hour. C. 30.5 ml/hour. D. 32.4 ml/hour.

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.
