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

“Tell me what your pain feels like.” This question allows the nurse to assess the quality of pain, which is one of the characteristics of pain that can help determine its cause and treatment. Quality of pain refers to how the client describes the pain, such as sharp, dull, burning, throbbing, etc.

Choice A is wrong because it assesses the intensity of pain, not the quality. Intensity of pain is how much the pain hurts on a scale of 0 to 10 or using other methods.

Choice C is wrong because it assesses the precipitating factors of pain, not the quality. Precipitating factors are events or activities that trigger or worsen the pain.

Choice D is wrong because it assumes a specific quality of pain without asking the client. The nurse should not suggest words to describe the pain, but rather let the client use their own words.

A. Inform the unit supervisor. B. Notify the health care provider. C. Document the error in the client’s medical record. D. Record the error on the appropriate quality improvement report.

Correct Answer is B

Explanation

Notify the health care provider. The nurse should take this action first because the provider can prescribe appropriate interventions to prevent or minimize harm to the client.

The nurse should also inform the unit supervisor, document the error in the client’s medical record, and record the error on the appropriate quality improvement report, but these are not the priority actions.

Choice A is wrong because informing the unit supervisor is not the most urgent action. The supervisor can provide support and guidance to the nurse, but cannot prescribe interventions for the client.

Choice C is wrong because documenting the error in the client’s medical record is not the most urgent action.

The nurse should document the error after notifying the provider and assessing the client. Documentation should include the medication name, dose, route, time, client’s response, and actions taken.

Choice D is wrong because recording the error on the appropriate quality improvement report is not the most urgent action.

The nurse should record the error after notifying the provider and assessing the client. The report should include a factual description of what happened and what was done.
