ATI LPN Mental Health Exam IV Questions
Extract:
Question 1 of 5
A nurse is collecting data on a client to check for orthostatic hypotension. Which of the following actions should the nurse take first?
Correct Answer: D
Rationale: Checking BP supine first establishes a baseline for orthostatic hypotension (drop >20/10 mmHg on position change). Standing (
A) and sitting (
C) follow, with measurements (
B) after each. Supine BP is the initial step per protocol.
Question 2 of 5
A nurse is reinforcing teaching about warfarin with a client who has a new onset of atrial fibrillation. Which of the following statements should the nurse include in the teaching?
Correct Answer: C
Rationale: Warfarin prevents strokes in atrial fibrillation by reducing clot formation (via vitamin K inhibition), not dissolving clots (
A), slowing ventricles (B, antiarrhythmic role), or restoring rhythm (
D). Stroke prevention is its primary role due to atrial clot risk.
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
Which of the following is an impulse control disorder?
Correct Answer: D
Rationale: Deceitfulness: Deceitfulness is more associated with antisocial personality disorder rather than impulse control disorders. Aggressive conduct: Aggressive conduct is associated with conduct disorder, not specifically with impulse control disorders. Serious rule violations: Serious rule violations are characteristic of conduct disorder. Pyromania: Pyromania is an impulse control disorder characterized by the recurrent urge to set fires.
Question 5 of 5
A nurse is caring for a client who has deep vein thrombosis (DVT). The client has received intravenous (IV) heparin for the past 5 days and now has a new prescription for oral warfarin in addition to the heparin. The client asks the nurse if both medications are necessary. Which of the following is an appropriate response by the nurse?
Correct Answer: D
Rationale: Heparin acts quickly to prevent clot growth, while warfarin takes days to reach therapeutic INR (2.0–3.0). Overlap ensures anticoagulation continuity. Neither dissolves clots (
A), heparin doesn’t enhance warfarin (
B), and deferring explanation (
C) avoids education. D reflects standard DVT protocol.
