1. A client with an NG tube is receiving intermittent feedings through an open system. Which of the following actions should the nurse take first?
- A. Rinse the feeding bag with water between feedings
- B. Tell the client to keep the head of the bed elevated at least 30°
- C. Make sure the enteral formula is at room temperature
- D. Wipe the top of the formula can with alcohol
Correct answer: B
Rationale: The correct answer is to tell the client to keep the head of the bed elevated at least 30°. Elevating the head of the bed prevents aspiration of the enteral formula, which is a priority in caring for a client with an NG tube. This action helps in reducing the risk of complications such as pneumonia. Choices A, C, and D are incorrect. While rinsing the feeding bag, ensuring the enteral formula temperature, and maintaining cleanliness are important aspects of enteral feeding care, the priority is to prevent aspiration by keeping the head of the bed elevated. These actions can be implemented after ensuring the client's safety by maintaining the correct bed position.
2. A nurse is assessing a day-old infant for jaundice. Which of the following is the best method for this?
- A. Applying pressure over a bony area such as the forehead and evaluating the skin color after the pressure is removed
- B. Assessing the color of the infant’s hands and feet
- C. Assessing the infant’s tongue
- D. Assessing the infant’s arms and legs
Correct answer: A
Rationale: The correct answer is A. Applying pressure over a bony area and evaluating the skin color after the pressure is removed is the most accurate method for assessing jaundice in a day-old infant. This technique helps in identifying any yellowing of the skin, which is a key indicator of jaundice. Choices B, C, and D are less effective methods for assessing jaundice in a newborn. Assessing the color of the hands and feet may not give a reliable indication of jaundice, while evaluating the tongue, arms, and legs are not as specific or accurate as applying pressure over a bony area.
3. A client with rheumatoid arthritis is prescribed methotrexate. Which instruction should the nurse include in the teaching plan?
- A. Avoid taking folic acid supplements
- B. Report any signs of infection immediately
- C. Limit fluid intake to prevent edema
- D. Increase intake of high-calcium foods
Correct answer: B
Rationale: The correct instruction that the nurse should include in the teaching plan for a client prescribed methotrexate is to report any signs of infection immediately. Methotrexate can suppress the immune system, making the individual more susceptible to infections. Reporting signs of infection promptly allows for timely intervention. Choices A, C, and D are incorrect. Avoiding folic acid supplements is not recommended because methotrexate can lead to folate deficiency, so supplementation may be necessary. There is no direct correlation between fluid intake limitation and methotrexate use. Increasing high-calcium foods is not specifically related to methotrexate therapy for rheumatoid arthritis.
4. Food energy is commonly expressed in kilocalories and in what other unit?
- A. kilojoules
- B. kilograms
- C. kilometers
- D. kilonewtons
Correct answer: A
Rationale: Food energy is commonly expressed in kilocalories and kilojoules. Kilocalories and kilojoules are both units of energy commonly used to measure the energy content of food. Kilograms, kilometers, and kilonewtons are units of mass, distance, and force, respectively, and are not used to express food energy.
5. A parent receives a note from the school that a student in class has head lice. The parent calls the school nurse to ask how to check for head lice. What instructions should the nurse provide?
- A. Ask the child where it itches.
- B. Check to see if your dog has ear mites.
- C. Look along the scalp line for white dots.
- D. Observe between the fingers for red lines.
Correct answer: C
Rationale: The correct answer is to look along the scalp line for white dots (nits) when checking for head lice. White dots are indicative of head lice infestation. Itching alone, as mentioned in choice A, is not a reliable indicator of head lice. Choice B is irrelevant as it refers to checking for ear mites in a dog, not head lice in a human. Observing between the fingers for red lines, as in choice D, is not a method to check for head lice.
