HESI CAT Exam 2022
1. A client is receiving lidocaine IV at 3 mg/minute. The pharmacy dispenses a 500 ml IV solution of normal saline (NS) with 2 grams of lidocaine. The nurse should regulate the infusion pump to deliver how many ml/hour?
- A. 18
- B. 27
- C. 36
- D. 45
Correct answer: D
Rationale: The infusion rate is calculated based on the concentration of lidocaine and the prescribed rate of infusion. First, convert lidocaine's weight to milligrams (2 grams = 2000 mg). Then, use the formula: (Total volume in ml * dose in mg) / 60 minutes. For this case, (500 ml * 2000 mg) / 60 minutes = 45 ml/hour. Therefore, the correct answer is D. Choices A, B, and C are incorrect as they do not reflect the accurate calculation based on the provided concentration and infusion rate.
2. A 46-year-old male client who had a myocardial infarction 24 hours ago comes to the nurse’s station fully dressed and wanting to go home. He tells the nurse that he is feeling much better at this time. Based on this behavior, which nursing problem should the nurse formulate?
- A. Anxiety related to treatment plan
- B. Deficient knowledge of lifestyle changes
- C. Ineffective coping related to denial
- D. Decisional conflict due to stress
Correct answer: C
Rationale: The correct answer is C: 'Ineffective coping related to denial.' The client's behavior of wanting to go home and feeling much better shortly after a myocardial infarction indicates denial of the severity of his condition. This denial can lead to ineffective coping mechanisms, hindering his recovery and treatment. Choices A, B, and D are incorrect because the client's behavior is not primarily driven by anxiety about the treatment plan, deficient knowledge of lifestyle changes, or decisional conflict due to stress, but rather by denial and ineffective coping mechanisms.
3. The healthcare provider receives a report on four clients who are complaining of increased pain. Which client requires immediate attention by the healthcare provider?
- A. Burning pain due to a Morton’s neuroma
- B. Sharp pain related to a crushed femur
- C. Paresthesia of fingers due to carpal tunnel syndrome
- D. Stinging pain related to plantar fasciitis
Correct answer: B
Rationale: Sharp pain related to a crushed femur indicates a severe condition and potential serious complications that require immediate attention. Crushed femur can lead to severe bleeding, nerve damage, or compartment syndrome, which are critical and life-threatening. The other choices, although painful, are less likely to present immediate life-threatening issues. Morton’s neuroma, carpal tunnel syndrome, and plantar fasciitis are painful conditions but are not typically associated with urgent, life-threatening complications like a crushed femur.
4. Four clients arrive on the labor and delivery unit at the same time. Which client should the nurse assess first?
- A. A 38-week primigravida who reports contractions occurring every 10 minutes
- B. A 39-week primigravida with a biophysical profile score of 5 out of 8
- C. A 41-week multigravida who is scheduled for induction of labor today
- D. A 36-week multigravida with a prescription for serial blood pressure
Correct answer: B
Rationale: The correct answer is B. A biophysical profile score of 5 out of 8 indicates potential fetal distress, necessitating immediate assessment to ensure the well-being of the fetus. The other options, while important, do not suggest an immediate threat to the fetus' health. The 38-week primigravida with contractions every 10 minutes may be in early labor, the 41-week multigravida scheduled for induction can be assessed after addressing the immediate concern, and the 36-week multigravida with serial blood pressure can be assessed after ensuring the client with potential fetal distress is stabilized.
5. What should the nurse monitor for during the IV infusion of vasopressin (Pitressin) in a client with bleeding esophageal varices?
- A. Vasodilatation of the extremities
- B. Chest pain and dysrhythmia
- C. Hypotension and tachycardia
- D. Decreasing GI cramping and nausea
Correct answer: B
Rationale: During the IV infusion of vasopressin in a client with bleeding esophageal varices, the nurse should monitor for chest pain and dysrhythmia. Vasopressin is a vasoconstrictor that can cause cardiovascular effects, including chest pain and dysrhythmias. Options A, C, and D are incorrect as vasopressin is not expected to cause vasodilatation of the extremities, hypotension, tachycardia, or improvements in GI symptoms such as cramping and nausea.
