100% Correct - OA Remediation Guide .
1. A patient is prescribed furosemide (Lasix). Which electrolyte imbalance should
the nurse monitor most closely?
A. Hyperkalemia
B. Hypokalemia
C. Hypernatremia
D. Hypocalcemia
Correct Answer: B
Rationale: Furosemide is a loop diuretic that inhibits sodium and chloride reabsorption
in the ascending loop of Henle, which also increases potassium excretion. This puts the
patient at significant risk for hypokalemia (low potassium levels).
2. A nurse is preparing to insert a Foley catheter. Which action is most important
to prevent infection?
A. Use sterile technique during insertion
B. Clean the perineum after insertion
C. Apply a lubricant to the catheter tip
D. Use a closed drainage system
Correct Answer: A
Rationale: While all options are part of proper catheter care, the most critical action to
,prevent a catheter-associated urinary tract infection (CAUTI) is the use of sterile
technique during insertion to avoid introducing pathogens into the bladder.
3. A patient reports sudden chest pain radiating to the left arm. What is the
nurse's priority action?
A. Obtain a detailed family history
B. Administer prescribed nitroglycerin and monitor vital signs
C. Schedule an ECG for tomorrow
D. Encourage the patient to rest
Correct Answer: B
Rationale: Chest pain radiating to the left arm is a classic sign of a myocardial infarction
(heart attack). The priority action is prompt assessment and administration of prescribed
medications like nitroglycerin to relieve pain and reduce cardiac workload while
monitoring vital signs.
4. Which of the following is a contraindication for administering aspirin?
A. History of hypertension
B. History of peptic ulcer disease
C. Mild seasonal allergies
D. Osteoarthritis
Correct Answer: B
Rationale: Aspirin is an NSAID that inhibits platelet aggregation and can irritate the
gastric mucosa. It is contraindicated in patients with a history of peptic ulcer
disease because it significantly increases the risk of gastrointestinal bleeding.
5. A client is prescribed warfarin. Which laboratory value should the nurse monitor
to evaluate therapeutic effectiveness?
A. aPTT
B. INR
, C. Platelet count
D. Bleeding time
Correct Answer: B
Rationale: Warfarin is an anticoagulant that works by inhibiting Vitamin K-dependent
clotting factors. Its therapeutic effect is measured using the International Normalized
Ratio (INR) . For most indications, the therapeutic goal is an INR of 2.0-3.0.
6. A client is prescribed metformin for type 2 diabetes. Which of the following
instructions should the nurse include?
A. "Take this medication on an empty stomach"
B. "Hold this medication for 48 hours before and after IV contrast dye"
C. "Expect your blood glucose to decrease immediately"
D. "This medication causes significant weight gain"
Correct Answer: B
Rationale: Metformin carries a risk of lactic acidosis. It should be held for 48 hours
before and after receiving IV contrast dye (which can impair kidney function) to prevent
the drug from accumulating to dangerous levels in the bloodstream.
7. Which nursing action is essential before administering digoxin?
A. Assess apical pulse for 1 full minute
B. Monitor temperature
C. Check respiratory rate only
D. Administer with antacids
Correct Answer: A
Rationale: Digoxin has a narrow therapeutic index and can cause bradycardia and heart
block. The nurse must check the apical pulse for one full minute before
administration. If the pulse is below 60 beats per minute (or per facility policy), the dose
should be withheld and the provider notified.
, 8. A nurse is caring for a client who has a new diagnosis of diabetes mellitus.
Which of the following actions demonstrates the assessment phase of the nursing
process?
A. Administer insulin as prescribed
B. Check the client's blood glucose level
C. Teach the client how to use a glucometer
D. Evaluate the effectiveness of dietary changes
Correct Answer: B
Rationale: The nursing process consists of five steps: Assessment, Diagnosis, Planning,
Implementation, and Evaluation. Assessment involves collecting subjective and
objective data. Checking a client's blood glucose level is a data collection activity,
placing it in the assessment phase.
9. A client is on airborne precautions. Which of the following PPE should the nurse
wear?
A. Surgical mask
B. N95 respirator
C. Gown and gloves only
D. Eye protection only
Correct Answer: B
Rationale: Airborne precautions are used for diseases like tuberculosis, measles, or
chickenpox, which are transmitted via very small particles that can remain suspended in
the air. An N95 respirator (or higher) is required to filter these particles.
10. A client is receiving a blood transfusion and reports low back pain and chills.
Which action should the nurse take first?
A. Stop the transfusion
B. Notify the provider
