LPN Nutrition Practice Test
1. Which of the following is a function of carbohydrates in the body?
- A. They provide insulation and support for organs.
- B. They help regulate body temperature.
- C. They serve as the body's main structural components.
- D. They are the body's primary source of energy.
Correct answer: D
Rationale: The correct answer is D. Carbohydrates are the body's primary source of energy, fueling daily activities and bodily functions. Choice A is incorrect because insulation and organ support are primarily provided by adipose tissue and structural proteins, not carbohydrates. Choice B is incorrect because the regulation of body temperature is mainly controlled by processes like sweating and shivering, not carbohydrates. Choice C is incorrect because structural components like proteins are responsible for building tissues and organs, not carbohydrates.
2. An older homeless client visits the psychiatric clinic to obtain a prescription renewal for alprazolam (Xanax). During the health assessment, the client complains of chest pain. Which action should the RN take first?
- A. Refer the client to the cardiology unit.
- B. Obtain the client's blood pressure.
- C. Assess the client for substance abuse.
- D. Determine if Xanax was taken recently.
Correct answer: D
Rationale: Determining if Xanax was taken recently is crucial as it helps assess whether the chest pain is related to medication use or another issue, guiding appropriate immediate care. This action can provide essential information to address the client's current complaint effectively. Referring the client to the cardiology unit (Choice A) may be premature without assessing the Xanax use first. While obtaining the client's blood pressure (Choice B) is important, it is not the priority when the client presents with chest pain and a history of taking Xanax. Assessing the client for substance abuse (Choice C) is also important but is secondary to first determining the potential link between Xanax and the chest pain.
3. How does omeprazole work in treating a peptic ulcer?
- A. Increasing the production of gastric acid
- B. Neutralizing stomach acid
- C. Coating the stomach lining
- D. Reducing gastric acid secretion
Correct answer: D
Rationale: Omeprazole is a proton pump inhibitor that works by reducing gastric acid secretion. By inhibiting the enzyme responsible for pumping acid into the stomach, omeprazole helps decrease the acidity level in the stomach, providing relief from peptic ulcers. Option A is incorrect because omeprazole does not increase gastric acid production; instead, it decreases it. Option B is incorrect as omeprazole does not neutralize existing stomach acid but rather reduces its secretion. Option C is incorrect as omeprazole does not coat the stomach lining but acts on reducing acid secretion.
4. A client has been taking simvastatin for 3 days and calls the nurse at the clinic to report extreme muscle tenderness and pain. Which is the most appropriate action?
- A. Notify the health care provider.
- B. Review the medication with the client.
- C. Advise the client to avoid grapefruit juice.
- D. Remind the client to limit physical activity until evaluated by the health care provider.
Correct answer: A
Rationale: Extreme muscle tenderness and pain in a client taking simvastatin could indicate rhabdomyolysis, a serious condition. Promptly notifying the health care provider is crucial to evaluate and manage this potential medical emergency. Reviewing the medication with the client may not address the urgency of the situation. Advising the client to avoid grapefruit juice is not directly related to the client's current symptoms. Reminding the client to limit physical activity until evaluated by the health care provider is not appropriate as the client's symptoms should be assessed by a professional first.
5. Which of the following is considered normal for the neonate?
- A. Chest Circumference: 10 to 13 inches
- B. Length: 16 to 22 inches
- C. Weight: 1,500 to 4,000 g
- D. Head Circumference: 12.6 to 14.5 inches
Correct answer: D
Rationale: A normal head circumference for a neonate typically falls within the range of 12.6 to 14.5 inches. Choice A is incorrect because the chest circumference for a neonate is usually smaller. Choice B is incorrect as the length of a neonate is typically shorter. Choice C is incorrect as the weight of a neonate is usually measured in grams and falls within a different range.
