HESI RN
HESI Pharmacology Practice Exam
1. When reviewing laboratory results for a client receiving tacrolimus (Prograf), which laboratory result would indicate to the nurse that the client is experiencing an adverse effect of the medication?
- A. Blood glucose of 200 mg/dL
- B. Potassium level of 3.8 mEq/L
- C. Platelet count of 300,000 cells/mm³
- D. White blood cell count of 6000 cells/mm³
Correct answer: A
Rationale: An elevated blood glucose level of 200 mg/dL indicates an adverse effect of tacrolimus. This finding suggests hyperglycemia, which is a known adverse effect of the medication. Other potential adverse effects of tacrolimus include neurotoxicity and hypertension. Monitoring blood glucose levels is crucial to detect and manage this adverse effect promptly. Choices B, C, and D are not directly associated with adverse effects of tacrolimus. Potassium, platelet count, and white blood cell count are important parameters to monitor for other reasons but not specifically for detecting adverse effects of tacrolimus.
2. A nurse is suctioning a client through a tracheostomy tube. During the procedure, the client begins to cough, and the nurse hears a wheeze. The nurse tries to remove the suction catheter from the client’s trachea but is unable to do so. What should the nurse do first?
- A. Call a code
- B. Contact the physician
- C. Administer a bronchodilator
- D. Disconnect the suction source from the catheter
Correct answer: D
Rationale: Inability to remove a suction catheter is a critical situation that may indicate the presence of bronchospasm and bronchoconstriction, as evidenced by the client coughing and wheezing. The immediate action for the nurse is to disconnect the suction source from the catheter, allowing the catheter to remain in the trachea. By doing so, the nurse can then connect the oxygen source to the catheter to provide essential oxygenation to the client. Contacting the physician is necessary to notify them of the situation and to obtain further orders, typically for an inhaled bronchodilator to relieve the bronchospasm. Administering a bronchodilator without physician's orders is not within the nurse's scope of practice and should not be the first action. Calling a code would be excessive at this point and should only be done if the client's condition deteriorates and immediate resuscitation is required.
3. A child is admitted to the pediatric unit with a diagnosis of suspected meningococcal meningitis. Which admission orders should the nurse do first?
- A. Institute seizure precautions
- B. Monitor neurologic status every hour
- C. Place in respiratory/secretion precautions
- D. Cefotaxime IV 50 mg/kg/day divided q6h
Correct answer: C
Rationale: The correct answer is to place the child in respiratory/secretion precautions first. Meningococcal meningitis is highly contagious, and respiratory precautions are essential to prevent the spread of the infection. Seizure precautions may be necessary but are not the priority upon admission. Monitoring neurologic status is important but not the initial action needed. While antibiotic therapy like Cefotaxime is crucial, implementing isolation precautions to prevent transmission takes precedence in this situation.
4. The RN is admitting a male client who takes lithium carbonate (Eskalith) twice a day. Which information should the RN report to the HCP immediately?
- A. Short-term memory loss.
- B. Five-pound weight gain.
- C. Decreased affect.
- D. Nausea and vomiting.
Correct answer: D
Rationale: Nausea and vomiting are signs of potential lithium toxicity, which is a serious condition requiring immediate attention. These symptoms can indicate a dangerous level of lithium in the body that can lead to severe complications. Short-term memory loss (A), five-pound weight gain (B), and decreased affect (C) are important to monitor but are not as immediately concerning as symptoms of potential toxicity like nausea and vomiting.
5. The client with peripheral artery disease has been prescribed clopidogrel (Plavix). The nurse understands that more teaching is necessary when the client states which of the following?
- A. I should not be surprised if I bruise more easily or if my gums bleed a little when brushing my teeth.
- B. It is important to take this medicine with food to enhance its effectiveness and minimize stomach upset.
- C. I should stop taking Plavix if it makes me feel weak and dizzy.
- D. The doctor prescribed this medicine to make my platelets less likely to stick together and help prevent clots from forming.
Correct answer: C
Rationale: The correct answer is C. Weakness, dizziness, and headache are common adverse effects of Plavix and should be reported. It is essential to consult a physician before stopping Plavix as it plays a crucial role in preventing platelets from sticking together and forming clots. Choices A, B, and D are incorrect. Choice A is a common side effect of Plavix and does not indicate a need for further teaching. Choice B is incorrect because taking Plavix with or without food can affect its absorption and effectiveness. Choice D correctly explains the purpose of prescribing Plavix to prevent clot formation.
