ATI LPN Mental Health Exam IV Questions
Extract:
Question 1 of 5
A nurse is caring for a client who has a prescription for digoxin 0.25 mg PO daily. The amount available is digoxin 0.125 mg/tablet. How many tablets should the nurse administer per dose? (Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 2
Rationale: Prescribed dose: 0.25 mg; available: 0.125 mg/tablet. Calculation: 0.25 ÷ 0.125 = 2 tablets. Digoxin treats heart failure; accurate dosing prevents toxicity (therapeutic range 0.5–2 ng/mL). Rounded to whole number as instructed.
Question 2 of 5
A person has drunk a large amount of alcohol over a short time. Which of the following can result from ingesting a large amount of alcohol?
Correct Answer: B
Rationale: Increased body temperature: Alcohol consumption typically causes vasodilation, which can lead to a decrease in body temperature, not an increase. Cardiac dysrhythmias: Large amounts of alcohol can affect the heart's electrical system, leading to cardiac dysrhythmias. Hypotension: Alcohol is a vasodilator, which can lead to a drop in blood pressure (hypotension). Bradycardia: Alcohol typically causes tachycardia (increased heart rate), not bradycardia (decreased heart rate).
Question 3 of 5
A nurse is reinforcing teaching with a client who has hypertension and inquires if there is a herbal supplement that can be used to help lower blood pressure. The nurse should identify which of the following herbal supplements the client can use to help lower blood pressure?
Correct Answer: B
Rationale: Garlic’s allicin relaxes blood vessels, reducing blood pressure, supported by studies in hypertension. Probiotics aid gut health, ginger has weaker evidence, and valerian treats insomnia—not BP. Garlic is the strongest evidence-based option.
Question 4 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 5 of 5
A nurse is assisting with teaching a class about documenting blood pressure. The nurse should include documenting which of the following information?
Correct Answer: B, C, E
Rationale: Documenting interventions (
B), patient response (
C), and site (E) ensures care continuity and accuracy (e.g., arm vs. leg affects readings). Frequency (
A) and person (
D) are useful but less critical for immediate clinical decisions. B, C, E are essential per nursing standards.
