LPN Nutrition Practice Test
1. What is the primary source of energy for the brain and nervous system?
- A. Protein
- B. Fat
- C. Carbohydrate
- D. Glucose
Correct answer: D
Rationale: Glucose is the correct answer as it is the primary source of energy for the brain and nervous system. The brain relies heavily on glucose to function optimally. While protein and fat play essential roles in the body, they are not the primary sources of energy for the brain and nervous system. Carbohydrates, on the other hand, are broken down into glucose, which is then used as fuel by the brain and nervous system.
2. A male client is admitted to the mental health unit because he was feeling depressed about the loss of his wife and job. The client has a history of alcohol dependency and admits that he was drinking alcohol 12 hours ago. Vital signs are: temperature, 100 F, pulse 100, and BP 142/100. The nurse plans to give the client lorazepam (Ativan) based on which priority nursing diagnosis?
- A. Risk for injury related to suicidal ideation.
- B. Risk for injury related to alcohol detoxification.
- C. Knowledge deficit related to ineffective coping.
- D. Health-seeking behaviors related to personal crisis.
Correct answer: B
Rationale: The most important nursing diagnosis is related to alcohol detoxification (B) because the client has elevated vital signs, a sign of alcohol detoxification. Giving lorazepam (Ativan) to address the elevated vital signs due to alcohol withdrawal is a priority. Addressing the risk for injury related to suicidal ideation (A) should come after stabilizing the client's physiological state. Both (C) and (D) can be addressed once immediate safety needs are met, but the priority is managing the alcohol detoxification to prevent potential complications.
3. A nurse observes a family member administer a rectal suppository by having the client lie on the left side for the administration. The family member pushed the suppository until the finger went up to the second knuckle. After 10 minutes, the client was told by the family member to turn to the right side. What is the appropriate comment for the nurse to make?
- A. Why don’t we now have the client turn back to the left side?
- B. That was done correctly. Did you have any problems with the insertion?
- C. Let’s check to see if the suppository is in far enough.
- D. Did you feel any stool in the intestinal tract?
Correct answer: B
Rationale: Choice B is the correct answer because the family member's actions in administering the rectal suppository were correct. Providing positive feedback and asking if there were any problems with the insertion is an appropriate response. Choice A is incorrect because there is no need to have the client turn back to the left side after the suppository has been administered. Choice C is incorrect as there is no indication that the suppository was not inserted correctly, so there is no need to check if it is in far enough. Choice D is incorrect because feeling stool in the intestinal tract is not relevant to the administration of a rectal suppository.
4. After a hip replacement surgery, a client is instructed to use an abduction pillow while in bed. What is the primary purpose of this device?
- A. To reduce the risk of blood clots.
- B. To prevent hip dislocation.
- C. To improve circulation in the legs.
- D. To alleviate pain and discomfort.
Correct answer: B
Rationale: The primary purpose of using an abduction pillow after hip replacement surgery is to prevent hip dislocation. The abduction pillow keeps the legs separated, which reduces the risk of hip dislocation by preventing excessive internal rotation and adduction of the hip joint. Choices A, C, and D are incorrect as the main goal of using the abduction pillow is to maintain proper positioning and stability of the hip joint to prevent dislocation, rather than addressing blood clots, circulation, or pain relief.
5. The nurse is preparing to administer a subcutaneous injection of insulin to a client with diabetes. What is the best site for the nurse to select for this injection?
- A. Ventrogluteal site
- B. Dorsogluteal site
- C. Deltoid site
- D. Abdomen
Correct answer: D
Rationale: The correct answer is 'D: Abdomen.' The abdomen is the best site for insulin injections as it provides a larger area with consistent absorption rates due to the high vascularity of the area. The subcutaneous tissue in the abdomen allows for a more predictable and consistent absorption of insulin compared to other sites. Ventrogluteal and dorsogluteal sites are not commonly used for insulin injections due to the risk of hitting the sciatic nerve or causing tissue damage. The deltoid site is more commonly used for intramuscular injections rather than subcutaneous injections like insulin.
