HESI RN
HESI Nutrition Practice Exam
1. A newly admitted adult client has a diagnosis of hepatitis A. The charge nurse should reinforce to the staff members that the most significant routine infection control strategy, in addition to hand washing, to be implemented is which of these?
- A. Apply appropriate signs outside and inside the room
- B. Apply a mask with a shield if there is a risk of fluid splash
- C. Wear a gown to change soiled linens from incontinence
- D. Have gloves on while handling bedpans with feces
Correct answer: D
Rationale: The correct answer is to have gloves on while handling bedpans with feces. Hepatitis A is transmitted through the fecal-oral route, and using gloves during such direct contact with feces is crucial in preventing the transmission of the infection. Choice A is not directly related to infection control for hepatitis A. Choice B is more relevant to preventing droplet transmission rather than fecal-oral transmission. Choice C is important for preventing contact transmission from soiled linens but is not as directly related to the mode of transmission of hepatitis A as using gloves when handling feces.
2. A nursing student is suctioning a client through a tracheostomy tube while a nurse observes. Which action by the student would prompt the nurse to intervene and demonstrate the correct procedure? Select all that apply.
- A. Setting the suction pressure to 60 mm Hg
- B. Applying suction throughout the procedure
- C. Assessing breath sounds before suctioning
- D. Placing the client in a supine position before the procedure
Correct answer: A
Rationale: The correct suction pressure for an adult client with a tracheostomy tube is typically between 80 to 120 mm Hg. Suction should be applied intermittently during catheter withdrawal to avoid damaging the airway. Assessing breath sounds before suctioning is important to ensure the procedure is necessary. Placing the client in a supine position before suctioning can compromise their airway; instead, the head of the bed should be elevated to facilitate proper drainage and reduce the risk of aspiration. Therefore, setting the suction pressure to 60 mm Hg is incorrect and would prompt the nurse to intervene and correct the procedure.
3. The healthcare provider is assessing a client with suspected syndrome of inappropriate antidiuretic hormone (SIADH). Which of the following laboratory findings is most consistent with this condition?
- A. Increased serum sodium
- B. Decreased urine specific gravity
- C. Decreased serum osmolality
- D. Increased serum potassium
Correct answer: C
Rationale: The correct answer is C: Decreased serum osmolality. Syndrome of inappropriate antidiuretic hormone (SIADH) is characterized by the excessive release of antidiuretic hormone (ADH), leading to water retention and dilutional hyponatremia. The dilution of sodium results in decreased serum osmolality. Option A is incorrect because SIADH causes hyponatremia, resulting in decreased serum sodium levels. Option B is incorrect because SIADH leads to concentrated urine with increased urine specific gravity. Option D is incorrect as SIADH does not typically affect serum potassium levels.
4. A client with a history of diabetes mellitus is admitted with a blood glucose level of 600 mg/dL. What type of insulin should the nurse prepare to administer to this client?
- A. Regular insulin
- B. NPH insulin
- C. Lispro insulin
- D. Glargine insulin
Correct answer: A
Rationale: In a client with a blood glucose level of 600 mg/dL, which indicates severe hyperglycemia or diabetic ketoacidosis, the nurse should prepare to administer regular insulin (A). Regular insulin has a rapid onset of action and is the preferred choice for immediate correction of high blood glucose levels. NPH insulin (B), lispro insulin (C), and glargine insulin (D) are not suitable for the rapid correction of severe hyperglycemia.
5. During a follow-up clinical visit, a mother tells the nurse that her 5-month-old son, who had surgical correction for tetralogy of Fallot, has rapid breathing, often takes a long time to eat, and requires frequent rest periods. The infant is not crying while being held, and his growth is in the expected range. Which intervention should the nurse implement?
- A. Stimulate the infant to cry to produce cyanosis
- B. Auscultate the heart and lungs while holding the infant
- C. Evaluate the infant for failure to thrive
- D. Obtain a 12-lead electrocardiogram
Correct answer: B
Rationale: Auscultating the heart and lungs while the infant is held is the most appropriate intervention to assess his current condition. This action allows the nurse to gather important information regarding the cardiovascular and respiratory status of the infant, which is crucial in evaluating his post-surgical recovery and overall well-being. Option A is incorrect as stimulating the infant to cry intentionally is not necessary and could cause distress. Option C is incorrect as the infant's growth is within the expected range, indicating no signs of failure to thrive. Option D is incorrect as obtaining a 12-lead electrocardiogram is not the initial intervention needed in this situation; assessing the heart and lungs through auscultation is more immediate and informative.
