HESI RN
HESI Nutrition Exam
1. To prevent unnecessary hypoxia during suctioning of a tracheostomy, what must the nurse do?
- A. Apply suction for no more than 10 seconds
- B. Maintain a sterile technique
- C. Lubricate 3 to 4 inches of the catheter tip
- D. Withdraw the catheter in a circular motion
Correct answer: A
Rationale: To prevent unnecessary hypoxia during suctioning of a tracheostomy, the nurse must apply suction for no more than 10 seconds. Prolonged suctioning can lead to hypoxia by removing too much oxygen from the patient. Maintaining a sterile technique (choice B) is important to prevent infection but does not directly relate to preventing hypoxia. Lubricating the catheter tip (choice C) helps with the insertion process but does not specifically address hypoxia prevention. Withdrawing the catheter in a circular motion (choice D) is not a standard practice during tracheostomy suctioning and does not contribute to preventing hypoxia.
2. A 4-year-old has been hospitalized for 24 hours with skeletal traction for treatment of a fracture of the right femur. The nurse finds that the child is now crying and the right foot is pale with the absence of a pulse. What should the nurse do first?
- A. Notify the healthcare provider
- B. Readjust the traction
- C. Administer the ordered PRN medication
- D. Reassess the foot in fifteen minutes
Correct answer: A
Rationale: In this situation, a pale foot with the absence of a pulse indicates compromised circulation, which is a critical emergency. The nurse should immediately notify the healthcare provider to address the circulation issue promptly. Reading the question and understanding the urgency is vital. Readjusting the traction, administering PRN medication, or waiting to reassess the foot in fifteen minutes are not appropriate actions when a child is experiencing compromised circulation.
3. A client with pneumonia is prescribed antibiotics. What is the most important teaching point for the nurse to provide?
- A. Instruct the client to rest as much as possible.
- B. Encourage increased fluid intake to thin secretions.
- C. Explain the importance of completing the entire course of antibiotics.
- D. Instruct the client to stop taking antibiotics once symptoms subside.
Correct answer: C
Rationale: The correct answer is C. Antibiotics must be taken for the entire prescribed duration to ensure that the infection is completely eradicated. Stopping antibiotics early, even if symptoms improve, can lead to a recurrence of the infection or antibiotic resistance. Choice A is incorrect because though rest is important, completing the antibiotic course is crucial. Choice B is incorrect as while hydration is beneficial, completing the antibiotics is the priority. Choice D is incorrect as stopping antibiotics prematurely can have negative consequences.
4. A client with type 2 diabetes mellitus is being discharged after receiving initial treatment. What should the nurse emphasize as a crucial instruction?
- A. Take insulin as prescribed, even if you are not eating.
- B. Avoid all forms of physical exercise to prevent hypoglycemia.
- C. Monitor blood glucose levels regularly and report any changes.
- D. Stop taking oral antidiabetic medication if your blood glucose levels are normal.
Correct answer: C
Rationale: Monitoring blood glucose levels regularly is a critical aspect of managing type 2 diabetes mellitus. This allows the individual to track their blood sugar levels, understand the effectiveness of the treatment plan, and detect any fluctuations promptly. Option A is incorrect because insulin should be taken based on a prescribed schedule that correlates with meals to prevent hypoglycemia or hyperglycemia. Option B is incorrect as physical exercise is beneficial for managing diabetes but should be done cautiously with adjustments in insulin or food intake. Option D is incorrect because discontinuing oral antidiabetic medications without healthcare provider guidance can lead to uncontrolled blood glucose levels.
5. When should the surgical correction of hypospadias in a newborn infant typically be done?
- A. Repair should be done by one month to prevent bladder infection.
- B. To form a proper urethra repair, it should be done after sexual maturity.
- C. Repairs typically should be done before the child is potty trained.
- D. Delaying the repair until school age reduces castration fears.
Correct answer: C
Rationale: Surgical repairs for hypospadias are typically recommended to be performed before the child is potty trained. This timing helps in avoiding complications, ensures better outcomes, and makes the surgical process smoother. Early correction also minimizes the psychological impact on the child regarding genital differences and can improve long-term psychological well-being. Choices A, B, and D are incorrect because repairing hypospadias at one month to prevent bladder infection, after sexual maturity to form a proper urethra, or delaying the repair until school age to reduce castration fears are not the standard recommendations. The optimal timing for surgical correction is before the child is potty trained to achieve the best results and psychological outcomes.
