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

Using teach back method to assess understanding. This method involves asking the client to repeat back the information or demonstrate the skill that was taught, which helps to evaluate their comprehension and retention.

It also allows the nurse to correct any misunderstandings and reinforce key points.

Choice A is wrong because teaching handouts are written on an eighth grade reading level may not be appropriate for older adult clients who may have lower literacy levels or cognitive impairments. The nurse should use simple, common language and large-print handouts that reflect the verbal information presented.

Choice C is wrong because the teaching plan is based on nutrition, medications, and safety may not address the individual needs and preferences of the older adult clients. The nurse should consider the preadmission functional abilities, health goals, and learning styles of each client when developing the plan of care.

Choice D is wrong because websites, video chats, and cell phone applications are introduced for learning may not be suitable or accessible for older adult clients who may have limited technology skills or sensory impairments. The nurse should use visual aids, face-to-face communication, and written instructions to enhance learning.

A. “Have you had thoughts about killing yourself?”. B. “What can’t you go on anymore?”. C. “Don’t think like that. It’s not true!”. D. “Have you talked to your doctor about these feelings?”.

Correct Answer is A

Explanation

“Have you had thoughts about killing yourself?” This is the best response because it directly assesses the client’s suicidal risk and shows empathy and concern.

The other choices are wrong because:

Choice B. “What can’t you go on anymore?” This is a vague and open-ended question that does not address the client’s immediate safety or emotional state.

Choice C. “Don’t think like that.

It’s not true!” This is a dismissive and invalidating response that does not acknowledge the client’s feelings or offer support.

Choice D. “Have you talked to your doctor about these feelings?” This is a deferring and avoiding response that does not explore the client’s situation or provide any intervention.
