Nutrition HESI Practice Exam
1. The nurse is reviewing laboratory results on a client with acute renal failure. Which one of the following should be reported immediately?
- A. Blood urea nitrogen 50 mg/dl
- B. Hemoglobin of 10.3 g/dl
- C. Venous blood pH 7.30
- D. Serum potassium 6 mEq/L
Correct answer: D
Rationale: A serum potassium level of 6 mEq/L indicates hyperkalemia, which can be life-threatening and requires immediate intervention. Hyperkalemia can lead to dangerous cardiac arrhythmias and must be addressed promptly. The other options are not as urgent. A blood urea nitrogen level of 50 mg/dl may indicate kidney dysfunction but does not require immediate intervention. Hemoglobin of 10.3 g/dl may suggest anemia, which needs management but is not an immediate threat. A venous blood pH of 7.30 may indicate acidosis, which is concerning but not as acutely dangerous as hyperkalemia.
2. A client with a history of seizures is being monitored with an electroencephalogram (EEG). Which of these interventions should the nurse perform to prepare the client for the test?
- A. Instruct the client to avoid caffeine for 8 hours before the test
- B. Explain the procedure to the client and obtain consent
- C. Administer anticonvulsant medication as ordered
- D. Instruct the client to wash their hair the morning of the test
Correct answer: A
Rationale: Instructing the client to avoid caffeine for 8 hours before the EEG is essential. This intervention helps ensure accurate test results by preventing stimulation of the nervous system, which could interfere with the interpretation of the brain's electrical activity. Explaining the procedure and obtaining consent are important steps but do not directly impact the test results. Administering anticonvulsant medication as ordered is a medical intervention and not a preparation step for the test. Instructing the client to wash their hair the morning of the test is not necessary for EEG preparation.
3. A client is receiving teaching about a high-fiber diet to manage constipation. Which statement indicates the best choice for a high-fiber diet?
- A. Eating one medium apple is a good snack option.
- B. Selecting a ½ cup of sweet potatoes for starch is a great choice.
- C. Choosing a ½ cup of bran cereal for breakfast is ideal.
- D. Opting for 1 ounce of almonds when hungry midday is recommended.
Correct answer: C
Rationale: The correct answer is C because bran cereal is a high-fiber food that can effectively alleviate constipation by promoting regular bowel movements. Option A, an apple, while a healthy snack, may not provide as much fiber as bran cereal. Option B, sweet potatoes, are nutritious but may not be as high in fiber as bran cereal. Option D, almonds, are a good source of healthy fats and protein but do not provide as much fiber as bran cereal.
4. A client with amyotrophic lateral sclerosis has a percutaneous endoscopic gastrostomy (PEG) tube for the administration of feedings and medications. Which nursing action is appropriate?
- A. Pulverize all medications into a powdery condition
- B. Squeeze the tube before using it to break up stagnant liquids
- C. Cleanse the skin around the tube daily with hydrogen peroxide
- D. Flush adequately with water before and after using the tube
Correct answer: D
Rationale: For a client with a percutaneous endoscopic gastrostomy (PEG) tube, flushing the tube adequately with water before and after use is essential. This action helps prevent clogging and ensures the proper administration of feedings and medications. Choice A is incorrect because pulverizing all medications into a powdery condition is not necessary for PEG tube administration. Choice B is incorrect as squeezing the tube to break up stagnant liquids may damage the tube. Choice C is incorrect because cleansing the skin around the tube daily with hydrogen peroxide can be too harsh and lead to skin irritation.
5. A nurse is caring for a new mother who is breastfeeding her term newborn. The newborn weighed 3.4 kg (7.5 lb) at birth and weighs 3.3 kg (7.3 lb) on the second day of life. The mother expresses concern about the weight loss and asks the nurse about the amount of her breast milk. Which of the following responses by the nurse is appropriate?
- A. Why don't you switch to formula to ensure your baby is eating enough?
- B. It is common for new mothers to worry that they are not producing enough milk for their baby.
- C. A healthy newborn can lose 6% of his birth weight before starting to gain weight.
- D. Your newborn will need to remain in the hospital so his weight can be monitored.
Correct answer: C
Rationale: The correct answer is C. A healthy newborn can lose up to 6% of their birth weight within the first few days of life, which is considered normal. This weight loss is usually due to fluid shifts and initial adjustments. Choices A, B, and D are incorrect. Choice A is inappropriate as switching to formula is not necessary at this point. Choice B, while acknowledging the mother's concerns, does not provide factual information about newborn weight loss. Choice D is unnecessary and may cause unnecessary stress to the mother and newborn since monitoring weight loss at home is sufficient unless there are other concerns.
