ATI LPN Mental Health Exam IV Questions
Extract:
Question 1 of 5
A nurse on a telemetry unit is reviewing the laboratory results for a client who has atrial fibrillation and is taking warfarin. Which of the following laboratory values should the nurse report to the provider?
Correct Answer: B
Rationale: PT of 45 seconds (normal 11–13.5 seconds) indicates excessive anticoagulation (therapeutic 1.5–2 times normal), risking bleeding on warfarin. Hgb (16 g/dL, 13.8–17.2 g/dL), aPTT (36 seconds, 21–35 seconds), and platelets (190,000/mm, 150,000–450,000/mm) are normal. PT requires urgent reporting.
Question 2 of 5
A nurse is preparing to administer digoxin to a client who has left-sided heart failure. Which of the following clinical manifestations should the nurse expect to see in this client? (Select all that apply.)
Correct Answer: A, C, D
Rationale: Left-sided heart failure causes pulmonary congestion:
A) Dyspnea from fluid in lungs;
C) Orthopnea from lying flat, worsening lung fluid;
D) Crackles from alveolar fluid.
B) Jugular vein distention is right-sided failure’s systemic congestion sign. A, C, D reflect left-sided pathology.
Question 3 of 5
A nurse is assessing the therapeutic International Normalized Ratio (INR) range for a patient receiving Warfarin. Which INR range below is therapeutic?
Correct Answer: A
Rationale: INR 2.0–3.0 is the standard therapeutic range for warfarin in conditions like atrial fibrillation or DVT, balancing clot prevention and bleeding risk. 4.0–5.0 and 3.0–4.9 risk bleeding; 1.0–2.0 is subtherapeutic, risking clots. 2.0–3.0 aligns with clinical guidelines.
Question 4 of 5
A nurse is making a home visit for a 16-year-old adolescent who attempted suicide. Which of the following behaviors should alert the nurse that the adolescent still has suicidal intent?
Correct Answer: A
Rationale: Planning to give his CD collection to his girlfriend: Giving away prized possessions is a common warning sign of suicidal intent, indicating that the person is preparing for their absence. Preferring to eat his meals while watching TV: This behavior is relatively normal and does not necessarily indicate suicidal intent. Stating that he wants to be with his peers more than with his parents: Wanting to spend time with peers is typical for adolescents and does not specifically indicate suicidal intent. Telling his parents that he doesn't want to talk about the attempt: Not wanting to discuss the attempt could be due to embarrassment, guilt, or other reasons, but it is not as direct an indicator of ongoing suicidal intent as giving away possessions.
Question 5 of 5
A nurse is caring for a client who has hypertension and is to start taking atenolol. The nurse should instruct the client to monitor for which of the following findings as an adverse effect of this medication?
Correct Answer: B
Rationale: Atenolol, a beta-blocker, slows heart rate by blocking beta-1 receptors, making bradycardia a key adverse effect to monitor (normal adult heart rate: 60–100 BPM; bradycardia <60 BPM). Cough is linked to ACE inhibitors, not beta-blockers. Constipation and headaches are not typical atenolol side effects; gastrointestinal and neurological effects are less common.
