**ATI TEAS 7 Practice Exam 2026**
*Practice Questions, Detailed Rationales & Complete Study Guide*
---
**1. A client is prescribed pyridostigmine for myasthenia gravis. Which finding indicates a cholinergic
crisis (overmedication)?**
A) Muscle weakness and fasciculations
B) Dry mouth and constipation
C) Tachycardia
D) Dilated pupils
💡 **RATIONALE** – Cholinergic crisis from excessive acetylcholinesterase inhibitor presents with
muscle weakness, fasciculations, diarrhea, salivation, and bradycardia. Dry mouth and dilated pupils are
anticholinergic effects.
✔️ **ANSWER** – A) Muscle weakness and fasciculations
---
**2. A nurse is teaching a client with a new prescription for lisinopril. Which adverse effect should the
client report immediately?**
A) Dry cough
B) Swelling of the lips and tongue
C) Headache
D) Fatigue
,💡 **RATIONALE** – Angioedema (swelling of lips/tongue/throat) is a rare but life-threatening adverse
effect of ACE inhibitors. Dry cough is common but not an emergency.
✔️ **ANSWER** – B) Swelling of the lips and tongue
---
**3. A client taking warfarin has an INR of 4.5. Which medication prescription should the nurse
anticipate?**
A) Vitamin K
B) Protamine sulfate
C) Naloxone
D) Flumazenil
💡 **RATIONALE** – Elevated INR indicates over-anticoagulation. Vitamin K is the antidote for warfarin.
Protamine sulfate reverses heparin.
✔️ **ANSWER** – A) Vitamin K
---
**4. A client with type 2 diabetes mellitus reports skipping meals but still taking metformin. Which
finding requires immediate intervention?**
A) Blood glucose 85 mg/dL
B) Nausea and diarrhea
C) Lactic acidosis symptoms (muscle pain, trouble breathing)
D) Weight loss of 2 lbs in 1 week
💡 **RATIONALE** – Metformin can cause lactic acidosis, a rare but fatal adverse effect. Skipping meals
on metformin does not cause hypoglycemia.
✔️ **ANSWER** – C) Lactic acidosis symptoms
,---
**5. A client is prescribed furosemide. Which laboratory value should the nurse monitor most closely?**
A) Serum sodium
B) Serum potassium
C) Serum calcium
D) Serum magnesium
💡 **RATIONALE** – Furosemide is a loop diuretic that causes significant potassium wasting
(hypokalemia), increasing arrhythmia risk.
✔️ **ANSWER** – B) Serum potassium
---
**6. A client with heart failure is prescribed digoxin. Which finding indicates digoxin toxicity?**
A) Heart rate 62 bpm
B) Yellow-tinged vision
C) Blood pressure 130/80 mmHg
D) Urinary output 40 mL/hr
💡 **RATIONALE** – Yellow-tinged or halo vision is a classic sign of digoxin toxicity, along with nausea,
vomiting, and bradycardia.
✔️ **ANSWER** – B) Yellow-tinged vision
---
**7. A nurse administers naloxone to a client with opioid overdose. Which finding indicates the
medication was effective?**
A) Respiratory rate increases from 8 to 16 breaths/min
B) Pupils become more constricted
, C) Blood pressure decreases from 140/90 to 110/70
D) The client falls asleep
💡 **RATIONALE** – Naloxone reverses opioid-induced respiratory depression. Increased respiratory
rate indicates effectiveness.
✔️ **ANSWER** – A) Respiratory rate increases from 8 to 16 breaths/min
---
**8. A client with seizures is prescribed phenytoin. Which instruction should the nurse include?**
A) "Take the medication with dairy products."
B) "Brush and floss your teeth regularly."
C) "Stop the medication if you feel dizzy."
D) "Take the medication only during a seizure."
💡 **RATIONALE** – Phenytoin causes gingival hyperplasia. Regular brushing and flossing help prevent
this.
✔️ **ANSWER** – B) "Brush and floss your teeth regularly."
---
**9. A client is receiving a heparin infusion. Which laboratory value indicates the therapy is
therapeutic?**
A) INR 2.5
B) aPTT 60 seconds (control 30 seconds)
C) Platelets 50,000/mm³
D) Hemoglobin 8 g/dL
💡 **RATIONALE** – Therapeutic heparin is monitored by aPTT, typically 1.5–2.5 times the control. INR
monitors warfarin.
