Question 1 of 5

Which of the following common habit of patients may cause microbes to repopulate and re-establish an infection?

A. The patient uses OTC drugs prophylacticallyB. The patient stops taking the drug when he or she begins to feel betterC. The patient switches to multiple drug therapy from single drug therapyD. The patient increases the drug dosage when he or she perceives that the therapeutic effect of the drug is slowing down.

Correct Answer: B

Rationale: Stopping antibiotics prematurely allows surviving microbes to multiply, leading to infection recurrence or resistance. Prophylactic OTC use, switching therapies, or increasing doses are less likely to directly cause repopulation if managed appropriately.

Question 2 of 5

Which of the following orders would the LPN question in a patient with Type I diabetes?

A. Insulin glargineB. AcarboseC. Insulin lisproD. Insulin regular

Correct Answer: B

Rationale: Acarbose is an alpha-glucosidase inhibitor used for Type 2 diabetes to slow carbohydrate absorption, not typically for Type 1 diabetes where insulin is the primary treatment due to the absence of insulin production. Insulin glargine, lispro, and regular are all appropriate for Type 1 diabetes management, providing basal or bolus insulin coverage.

Question 3 of 5

The nurse is asked why neomycin is given as a bowel prep before GI surgery. The nurse correctly replies that:

A. A reduction of intestinal bacteria lessens the possibility of postoperative infectionB. The bacteria found in the bowel cannot be destroyed after surgeryC. Abdominal surgery requires starting antibiotic therapy 4 days before surgeryD. Anesthesia makes the bowel resistant to an antibiotic after surgery

Correct Answer: A

Rationale: Neomycin reduces intestinal bacterial load, lowering the risk of postoperative infections during GI surgery. Bacteria can be treated post-surgery if needed, antibiotics aren’t required 4 days prior, and anesthesia doesn’t cause antibiotic resistance.

Question 4 of 5

Jennifer takes birth control pills. Recently she was diagnosed with a urinary tract infection and is taking ciprofloxacin (Cipro). To maximize the therapeutic effects of both types of drugs, what should the nurse tell Jennifer?

A. Treat the urinary tract infection with another drugB. Continue with both therapies simultaneouslyC. Complete the ciprofloxacin therapy and use a backup method of contraceptionD. Abstain from sexual activity until the end of ciprofloxacin therapy

Correct Answer: C

Rationale: Ciprofloxacin may reduce birth control pill effectiveness, risking pregnancy. Completing the antibiotic therapy with a backup contraception method ensures infection treatment and pregnancy prevention. Changing drugs or abstaining is less practical.

Question 5 of 5

A nurse is preparing to administer dexamethasone 3 mg PO. Available is dexamethasone 1.5 mg tablets. How many tablets should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Correct Answer: 2

Rationale:
To calculate the number of tablets, use the formula: Number of tablets = Dose (mg) ÷ Strength per tablet (mg). Given a dose of 3 mg and a tablet strength of 1.5 mg, Number of tablets = 3 ÷ 1.5 = 2 tablets. The answer is a whole number as required.
