HESI 799 RN Exit Exam Capstone
1. The psychiatric nurse is caring for clients in an adolescent unit. Which client requires the nurse's immediate attention?
- A. A 17-year-old client with schizophrenia who is pacing the hallways
- B. An 18-year-old client with antisocial behavior who is being yelled at by other clients
- C. A 16-year-old client with depression who refuses to eat meals
- D. A 15-year-old client with anxiety who is quietly reading in a corner
Correct answer: B
Rationale: The client with antisocial behavior being yelled at by peers may escalate the situation, potentially leading to violence or self-harm. Addressing the situation quickly helps prevent harm and de-escalates the conflict. Choices A, C, and D do not present immediate risks that require urgent intervention compared to the potential danger of a conflict escalating to violence with the client exhibiting antisocial behavior.
2. A client is admitted with deep vein thrombosis (DVT) and is receiving heparin therapy. What is the most important laboratory value to monitor during heparin therapy?
- A. Prothrombin time (PT)
- B. International normalized ratio (INR)
- C. Activated partial thromboplastin time (aPTT)
- D. Platelet count
Correct answer: C
Rationale: The activated partial thromboplastin time (aPTT) is the most important laboratory value to monitor during heparin therapy. It measures the intrinsic pathway of coagulation and is used to assess the effectiveness of heparin as an anticoagulant. Keeping the aPTT within the therapeutic range is crucial to prevent complications such as bleeding or clot formation. Prothrombin time (PT) and International normalized ratio (INR) are used to monitor warfarin therapy, not heparin. Platelet count is important to assess for thrombocytopenia, a potential side effect of heparin, but it is not the primary laboratory value to monitor the effectiveness of heparin therapy.
3. The nurse is planning to administer two medications at 0900. Which property of the drugs indicates a need to monitor the client for toxicity?
- A. Short half-life
- B. High therapeutic index
- C. Highly protein-bound
- D. Low bioavailability
Correct answer: C
Rationale: The correct answer is C, 'Highly protein-bound.' Drugs that are highly protein-bound can displace from protein-binding sites, leading to increased free drug levels in the blood, which can result in toxicity. Monitoring the client for toxicity is crucial when administering highly protein-bound drugs. Choices A, B, and D are incorrect. A short half-life does not necessarily indicate a need for monitoring toxicity; a high therapeutic index indicates a wide safety margin between the effective dose and the toxic dose, reducing the risk of toxicity; low bioavailability refers to the fraction of the drug that reaches the systemic circulation unchanged and does not directly relate to the risk of toxicity.
4. A client with myasthenia gravis (MG) is receiving immunosuppressive therapy. Recent lab tests show decreased serum magnesium. What nursing action is most important?
- A. Observe rhythm on telemetry monitor.
- B. Check for visual difficulties.
- C. Assess for hip and hand joint pain.
- D. Note the most recent hemoglobin level.
Correct answer: A
Rationale: Magnesium plays a crucial role in maintaining normal cardiac rhythms, particularly in patients with cardiac conditions. Abnormal levels can lead to arrhythmias, which is why continuous monitoring of the heart's electrical activity is important. Magnesium's effect on neuromuscular and cardiac function makes it essential to monitor its levels, and any discrepancies can impact treatment decisions. Checking for visual difficulties (choice B) may be important in MG but is not the priority in the context of decreased serum magnesium. Assessing for hip and hand joint pain (choice C) is not directly related to the issue of decreased serum magnesium. Noting the most recent hemoglobin level (choice D) is not the priority in this situation compared to monitoring the cardiac rhythm due to low magnesium levels.
5. A client receiving IV antibiotics for sepsis reports itching and has a rash on the chest. What is the nurse's first action?
- A. Administer an antihistamine as prescribed.
- B. Stop the infusion and notify the healthcare provider.
- C. Slow the infusion rate and monitor the client.
- D. Administer epinephrine subcutaneously.
Correct answer: B
Rationale: The correct action for the nurse to take first when a client receiving IV antibiotics for sepsis reports itching and a rash on the chest is to stop the infusion and notify the healthcare provider. This is crucial in preventing the allergic reaction from worsening. Administering an antihistamine (choice A) may address the symptoms but does not address the primary concern of stopping the infusion. Slowing the infusion rate and monitoring the client (choice C) may not be sufficient if the reaction is severe. Administering epinephrine subcutaneously (choice D) is not the first-line intervention for this situation.
