HESI RN
HESI RN CAT Exit Exam
1. A 2-year-old boy with short bowel syndrome has progressed to receiving enteral feedings only. Today his stools are occurring more frequently and have a more liquid consistency. His temperature is 102.2°F and he has vomited twice in the past four hours. Which assessment finding indicates that the child is becoming dehydrated?
- A. Occult blood in the stool
- B. Abdominal distention
- C. Elevated urine specific gravity
- D. Hyperactive bowel sounds
Correct answer: C
Rationale: Elevated urine specific gravity is a sign of dehydration in children. In the scenario provided, the child is experiencing increased stool frequency, liquid consistency, fever, and vomiting, indicating fluid loss and potential dehydration. Occult blood in the stool may suggest gastrointestinal bleeding but is not a direct indicator of dehydration. Abdominal distention can be seen in various conditions and is not specific to dehydration. Hyperactive bowel sounds are more commonly associated with increased bowel motility, not necessarily dehydration.
2. Several clients on a telemetry unit are scheduled for discharge in the morning, but a telemetry-monitored bed is needed immediately. The charge nurse should make arrangements to transfer which client to another medical unit?
- A. Learning to self-administer insulin injections after being diagnosed with diabetes mellitus
- B. Ambulatory following coronary artery bypass graft surgery performed six days ago
- C. Wearing a sling immobilizer following permanent pacemaker insertion earlier that day
- D. Experiencing syncopal episodes resulting from the dehydration caused by severe diarrhea
Correct answer: A
Rationale: The correct answer is A because transferring a stable client who is learning self-care, such as self-administering insulin injections after being diagnosed with diabetes mellitus, provides the needed telemetry-monitored bed without compromising the client's care. Choice B should not be transferred as the client is ambulatory following surgery and does not require telemetry monitoring. Choice C should not be transferred as the client is wearing a sling immobilizer following pacemaker insertion, which requires close monitoring. Choice D should not be transferred as the client is experiencing syncopal episodes due to severe dehydration, necessitating telemetry monitoring for immediate intervention.
3. A client is receiving total parenteral nutrition (TPN). Which assessment finding is most concerning to the nurse?
- A. Blood glucose level of 150 mg/dL.
- B. Blood pressure of 110/70 mm Hg.
- C. Serum albumin level of 3.5 g/dL.
- D. The client's temperature is 100.4°F (38°C).
Correct answer: D
Rationale: A temperature of 100.4°F (38°C) (D) is the most concerning finding for a client receiving total parenteral nutrition (TPN) as it may indicate an infection, which poses a significant risk. Monitoring blood glucose level (A), blood pressure (B), and serum albumin (C) are also important, but an elevated temperature suggests a potential serious complication that requires immediate attention.
4. The nurse is teaching a client with asthma to use a peak expiratory flow rate (PEFR) meter to manage asthma at home. The nurse knows the client understands the proper use of the meter when the client:
- A. Inhales as rapidly as possible when using the meter
- B. Records the highest of three readings
- C. Uses the meter after taking a bronchodilator
- D. Blows out forcefully into the meter after taking a deep breath
Correct answer: B
Rationale: The correct answer is B: 'Records the highest of three readings.' When using a peak expiratory flow rate (PEFR) meter, the client should record the highest of three readings to ensure an accurate measurement of their peak expiratory flow rate. Inhaling rapidly, using the meter after taking a bronchodilator, or blowing out forcefully into the meter after a deep breath are not correct techniques for using a PEFR meter and may lead to inaccurate results.
5. The nurse is caring for a client with end-stage renal disease (ESRD) who is scheduled for hemodialysis. Which assessment finding is most concerning?
- A. Blood pressure of 110/70 mmHg
- B. Heart rate of 110 beats per minute
- C. Fever of 100.4°F
- D. Respiratory rate of 24 breaths per minute
Correct answer: C
Rationale: A fever of 100.4°F is the most concerning assessment finding in a client with ESRD scheduled for hemodialysis. This elevation in temperature may indicate an underlying infection, which can lead to serious complications in individuals with compromised renal function. Prompt intervention is necessary to prevent the spread of infection and deterioration of the client's condition. The other vital signs mentioned, such as blood pressure, heart rate, and respiratory rate, while important to monitor, are within acceptable ranges and do not pose an immediate threat like a fever indicative of infection.
