Question 1 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?
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 2 of 5
A nurse is preparing to administer ondansetron 4 mg IM stat. The amount available is ondansetron for injection 2 mg/mL. How many mL 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: Using Volume (mL) = Dose (mg) ÷ Concentration (mg/mL), for a 4 mg dose and 2 mg/mL concentration, Volume = 4 ÷ 2 = 2 mL, a whole number as required.
Question 3 of 5
Which hormones that regulate blood glucose levels are secreted by the pancreas? (Select all that apply.)
Correct Answer: A,D
Rationale: Insulin lowers blood glucose by facilitating cellular uptake, and glucagon raises it by promoting glycogenolysis, both secreted by the pancreas. Growth hormone and antidiuretic hormone come from the pituitary, and estrogen from the ovaries, none directly regulating blood glucose from the pancreas.
Question 4 of 5
A nurse is preparing to administer diazepam 3 mg IM. The amount available is diazepam for injection 5 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 0.6
Rationale:
To calculate the volume, use: Volume (mL) = Dose (mg) ÷ Concentration (mg/mL). Given a dose of 3 mg and concentration of 5 mg/mL, Volume = 3 ÷ 5 = 0.6 mL, rounded to the nearest tenth as instructed.
Question 5 of 5
Which term is used to describe the stain of bacteria?
Correct Answer: B
Rationale: Gram-positive describes bacteria retaining crystal violet in Gram staining, indicating cell wall structure. Aerobic refers to oxygen needs, cocci to shape, and Bacillus to a genus, not staining.
