The LVN is preparing to give an enteric-coated tablet. Which action is correct?
Answer: Administer it whole without crushing or chewing
Enteric-coated tablets must be swallowed whole to protect the stomach lining and ensure the medication dissolves in the intestine.
A patient develops urticaria and wheezing shortly after a penicillin injection. The LVN recognizes this as:
Answer: An anaphylactic reaction requiring immediate intervention
Urticaria combined with wheezing after a medication indicates anaphylaxis, a life-threatening emergency requiring epinephrine and immediate intervention.
When using the Z-track method for IM injection, what is the primary purpose?
Answer: Prevent medication from leaking into subcutaneous tissue
The Z-track method displaces and then releases the tissue after injection, sealing the medication in the muscle and preventing leakage into subcutaneous tissue.
An LVN is preparing insulin. Which type of insulin is always drawn up first when mixing two insulins in one syringe?
Answer: Short-acting (clear) insulin
Clear (short-acting) insulin is drawn up before cloudy (long-acting) insulin to prevent contaminating the short-acting vial with long-acting insulin.
A patient taking a statin medication (e.g., atorvastatin) reports muscle pain and weakness. The LVN should:
Answer: Report to the charge nurse/physician immediately as this may indicate rhabdomyolysis
Muscle pain and weakness in a patient on statins may indicate rhabdomyolysis, a serious condition causing muscle breakdown and potential kidney failure.
Which assessment finding would cause the LVN to hold a scheduled dose of metoprolol?
Answer: Heart rate of 48 beats per minute
Metoprolol is a beta-blocker that slows heart rate; it should be held and the physician notified if the heart rate is below 60 bpm.
A medication order reads: 'Amoxicillin 500 mg PO TID x 10 days.' How many total doses will the patient receive?
Answer: 30 doses
TID means three times daily; 3 doses/day × 10 days = 30 total doses.
