HESI RN
HESI Fundamentals Practice Exam
1. A client is admitted with a diagnosis of diabetic ketoacidosis (DKA). Which intervention should the nurse implement first?
- A. Administer regular insulin IV.
- B. Administer IV fluids at 250 ml/hr.
- C. Administer sodium bicarbonate IV push.
- D. Administer furosemide (Lasix) IV push.
Correct answer: A
Rationale: Administering regular insulin IV (A) is the initial intervention for a client with diabetic ketoacidosis (DKA) to rapidly reduce blood glucose levels. This is vital in reversing the ketosis and acidosis seen in DKA. Administering IV fluids (B) helps to correct dehydration and electrolyte imbalances. Administering sodium bicarbonate (C) and furosemide (D) may be necessary depending on the client's condition, but insulin administration takes precedence in the management of DKA.
2. Which one of the following is not associated with poor maternal outcome?
- A. APH
- B. PPH
- C. Cord prolapse
- D. Pre-eclampsia
Correct answer: C
Rationale: Cord prolapse is not typically associated with poor maternal outcomes. Acute placental hemorrhage (APH - choice A) and postpartum hemorrhage (PPH - choice B) can lead to maternal morbidity and mortality due to excessive blood loss. Pre-eclampsia (choice D) is a serious pregnancy complication characterized by high blood pressure and signs of damage to other organ systems, which can result in severe maternal complications if not managed promptly. Cord prolapse, though concerning for fetal well-being, does not inherently pose direct risks to maternal health if managed appropriately, making it the correct answer in this context.
3. A female client is brought to the clinic by her daughter for a flu shot. She has lost significant weight since the last visit. She has poor personal hygiene and inadequate clothing for the weather. The client states that she lives alone and denies problems or concerns. What action should the nurse implement?
- A. Notify social services immediately if suspected elderly abuse is present.
- B. Discuss the need for mental health counseling with the daughter.
- C. Explain to the client the importance of taking better care of herself.
- D. Collect further data to determine whether self-neglect is occurring.
Correct answer: D
Rationale: In this scenario, the client presents with significant weight loss, poor hygiene, and inadequate clothing, which are concerning signs of self-neglect. Before taking action, it is crucial for the nurse to collect more data to determine the root cause of these issues. Jumping to conclusions or immediately involving social services without a thorough assessment could potentially harm the client or strain relationships. Discussing the need for mental health counseling with the daughter or simply advising the client to take better care of herself may not address the underlying problem of self-neglect. Therefore, the most appropriate initial action is for the nurse to collect further data to make an informed decision before taking the next steps.
4. A client with emphysema reports shortness of breath. What is the nurse's priority action?
- A. Administer oxygen therapy.
- B. Assess the client’s respiratory rate and effort.
- C. Prepare the client for intubation.
- D. Increase the client's oxygen flow rate.
Correct answer: B
Rationale: Shortness of breath in a client with emphysema may indicate respiratory distress. Assessing the client’s respiratory rate and effort is the first priority to determine the severity of the distress and guide appropriate interventions. Administering oxygen therapy (Choice A) could be necessary, but assessing the client first is crucial to tailor the intervention. Intubation (Choice C) is an invasive procedure that is not the initial priority. Increasing oxygen flow rate (Choice D) should only be done after a thorough assessment to avoid potential harm.
5. What is the most common cause of urinary tract infections (UTIs)?
- A. Escherichia coli infection
- B. Staphylococcus aureus infection
- C. Pseudomonas aeruginosa infection
- D. Klebsiella pneumoniae infection
Correct answer: A
Rationale: Escherichia coli is the most common cause of urinary tract infections (UTIs). It is responsible for the majority of UTIs, especially in women. E. coli is a normal inhabitant of the bowel and can enter the urinary tract through the urethra, leading to infection. Staphylococcus aureus, Pseudomonas aeruginosa, and Klebsiella pneumoniae are less common causes of UTIs compared to E. coli. Staphylococcus aureus typically causes skin and soft tissue infections, Pseudomonas aeruginosa is more commonly associated with healthcare-associated infections, and Klebsiella pneumoniae is known for causing pneumonia and other respiratory infections.
