LPN Nutrition Practice Test
1. What type of nutrient is needed by the body and must be supplied by foods?
- A. nutraceutical
- B. metabolic nutrient
- C. organic nutrient
- D. essential nutrient
Correct answer: D
Rationale: The correct answer is D, essential nutrient. Essential nutrients are substances that the body needs for normal functioning but cannot produce in sufficient amounts, so they must be obtained through the diet. Nutraceuticals (choice A) are products derived from food sources that are purported to provide extra health benefits beyond basic nutrition. Metabolic nutrients (choice B) and organic nutrients (choice C) are not standard terms used to describe nutrients needed by the body. Therefore, choices A, B, and C are incorrect.
2. The nurse has explained safety precautions and infant care to a primigravida mother and observes the mother as she gives care to her newborn during the first two days of rooming-in. Which action indicates the mother understands the instruction?
- A. Aspirates the newborn’s nares using a syringe
- B. Applies a dressing to the cord after the newborn’s bath
- C. Breastfeeds the infant every hour during the night
- D. Positions the infant supine in the crib to sleep
Correct answer: D
Rationale: Positioning the infant supine in the crib to sleep is the correct action that indicates the mother understands the instruction. This position is recommended to reduce the risk of Sudden Infant Death Syndrome (SIDS). Choice A is incorrect as it is not a routine or recommended practice to aspirate the newborn’s nares using a syringe without a specific medical indication. Choice B is incorrect because applying a dressing to the cord after the newborn's bath is not a standard care practice. Choice C is incorrect because breastfeeding every hour during the night is excessive and not a recommended feeding schedule for a newborn.
3. A nurse is preparing to administer a tuberculosis (TB) test to a client. Which of the following is the correct method for administering this test?
- A. Intradermal injection on the forearm
- B. Subcutaneous injection on the upper arm
- C. Intramuscular injection on the deltoid
- D. Oral administration
Correct answer: A
Rationale: The correct method for administering a tuberculosis (TB) test is through an intradermal injection on the forearm. This technique allows for the proper administration of the test under the skin to assess the body's response to the TB antigen. Choices B, C, and D are incorrect because the TB test specifically requires an intradermal injection, not subcutaneous, intramuscular, or oral administration.
4. When planning home care for a 72-year-old client with osteomyelitis requiring a 6-week course of intravenous antibiotics, what is the most important action by the nurse?
- A. Investigating the client's insurance coverage for home IV antibiotic therapy
- B. Determining if there are adequate hand washing facilities in the home
- C. Assessing the client's ability to participate in self-care and/or the reliability of a caregiver
- D. Selecting the appropriate venous access device
Correct answer: C
Rationale: Assessing the client's ability to participate in self-care or evaluating the reliability of a caregiver is crucial in ensuring adherence to the treatment plan. This action helps determine if the client can manage the intravenous antibiotics at home independently or if assistance is needed. Investigating insurance coverage, ensuring hand washing facilities, and selecting the venous access device are important aspects of care but assessing the client's ability for self-care and caregiver reliability takes precedence to promote treatment success and safety.
5. When taking blood pressure at the brachial artery, the nurse should place the client's arm in which position?
- A. Slightly above the level of the heart
- B. At the level of the heart
- C. At a level of comfort for the client
- D. Below the level of the heart
Correct answer: B
Rationale: When taking blood pressure at the brachial artery, it is crucial to place the client's arm at the level of the heart to ensure accurate measurement. Placing the arm above or below the heart level can lead to incorrect readings. Option A, placing the arm slightly above the heart level, would result in falsely lower blood pressure readings as gravity would assist in a lower value. Option C, placing the arm at a level of comfort for the client, may not align with the standardized technique required for accurate blood pressure assessment. Option D, placing the arm below the level of the heart, would likely yield falsely higher blood pressure readings due to increased hydrostatic pressure pushing the blood against gravity.
