HESI RN
HESI Fundamentals Practice Exam
1. A client with a diagnosis of hyperkalemia is receiving sodium polystyrene sulfonate (Kayexalate). Which laboratory value should the nurse monitor to evaluate the effectiveness of this medication?
- A. Serum sodium level.
- B. Serum potassium level.
- C. Serum calcium level.
- D. Serum glucose level.
Correct answer: B
Rationale: The correct answer is B: Serum potassium level. Sodium polystyrene sulfonate (Kayexalate) is used to treat hyperkalemia by exchanging sodium ions for potassium ions in the intestines, leading to potassium removal from the body. Monitoring the serum potassium level allows the nurse to assess the effectiveness of this medication in lowering the elevated potassium levels. Serum sodium (A), calcium (C), and glucose (D) levels are not directly impacted by the action of sodium polystyrene sulfonate.
2. When should a mother introduce solid foods to her infant? The mother of a 4-month-old baby girl asks the nurse when she should introduce solid foods to her infant. The mother states, 'My mother says I should put rice cereal in the baby’s bottle now.' The nurse should instruct the mother to introduce solid foods when her child exhibits which behavior?
- A. Stops rooting when hungry
- B. Opens mouth when food comes her way
- C. Awakens once for nighttime feedings
- D. Gives up a bottle for a cup
Correct answer: B
Rationale: The correct answer is 'B: Opens mouth when food comes her way.' Readiness for solid foods is indicated by the infant showing interest in food and being able to sit up with support. This behavior demonstrates the infant's readiness to start introducing solid foods in their diet. Choices A, C, and D are incorrect because stopping rooting when hungry, awakening once for nighttime feedings, and giving up a bottle for a cup are not indicators of readiness for solid foods in infants.
3. During the newborn admission assessment, the nurse palpates the newborn's scrotum and does not feel the testicles. Which assessment technique should the nurse perform next to verify the absence of testes?
- A. Observe the urethral opening on the surface of the penis when the newborn voids.
- B. Perform transillumination of the scrotal sac to visualize shadows of the testes.
- C. Use a fingertip to palpate the inguinal canal for a retractile or undescended testis.
- D. Measure the size of the scrotal sac for length and width.
Correct answer: C
Rationale: If the testes are not palpated in the scrotum, the next step is to check the inguinal canal for a retractile or undescended testis. This technique allows the nurse to determine if the testes are located within the inguinal canal rather than the scrotum. It is essential to assess for the presence of testes in the inguinal canal to ensure proper diagnosis and management of any potential issues related to testicular positioning.
4. A client has an indwelling catheter with continuous bladder irrigation after undergoing a transurethral resection of the prostate (TURP) 12 hours ago. Which finding at this time should be reported to the health care provider?
- A. Light pink urine
- B. Occasional suprapubic cramping
- C. Minimal drainage into the urinary collection bag
- D. Complaints of the feeling of pulling on the urinary catheter
Correct answer: C
Rationale: In a client with an indwelling catheter and continuous bladder irrigation post TURP, minimal drainage into the urinary collection bag should be reported to the health care provider. This finding could indicate a blockage in the catheter or a complication that requires immediate attention. Light pink urine (choice A) is expected due to bladder irrigation. Occasional suprapubic cramping (choice B) is common post-TURP. Complaints of the feeling of pulling on the urinary catheter (choice D) may indicate discomfort but do not suggest an urgent issue like a potential blockage.
5. After surgery, a male client with antisocial personality disorder frequently requests a specific nurse be assigned to his care and becomes belligerent when another nurse is assigned. What action should the charge nurse implement?
- A. Reassure the client that his request will be met whenever possible.
- B. Advise the client that assignments are not based on client requests.
- C. Ask the client to explain why he constantly requests the nurse.
- D. Encourage the client to verbalize his feelings about the nurse.
Correct answer: B
Rationale: The correct action for the charge nurse is to advise the client that assignments are not based on client requests. Clients with antisocial personality disorder may attempt to manipulate situations to their advantage. By setting clear boundaries and explaining that assignments are not based on client preferences, the nurse helps prevent manipulation and maintains a professional approach to care. Reassuring the client about his requests (Choice A) may encourage the inappropriate behavior to continue. Asking the client to explain his requests (Choice C) may further fuel the manipulation by providing an opportunity for the client to justify his actions. Encouraging the client to verbalize feelings (Choice D) does not address the underlying issue of manipulating the assignment process and may inadvertently reinforce the behavior.
