Nursing Elites

1. A nurse is preparing to administer heparin 8,000 units subcutaneously every eight hours. The amount available is heparin injection 10,000 units/mL. How many milliliters should the nurse administer per dose? (Round the answer to the nearest tenth)

• A. 0.8 mL
• B. 0.9 mL
• C. 10.0 mL
• D. 98.0 mL

Correct answer: A

Rationale: To determine the volume of heparin to administer per dose, divide the prescribed dose (8,000 units) by the concentration of heparin available (10,000 units/mL). 8000 units / 10000 units/mL = 0.8 mL. Therefore, the nurse should administer 0.8 mL per dose. Choice B, 0.9 mL, is incorrect as the correct calculation results in 0.8 mL. Choices C and D are significantly higher and incorrect, indicating an inaccurate calculation.

2. A client at 28 weeks of gestation is experiencing preterm labor. Which of the following medications should the nurse plan to administer?

• A. Oxytocin
• B. Nifedipine
• C. Dinoprostone
• D. Misoprostol

Correct answer: B

Rationale: Nifedipine is the correct choice because it is a calcium channel blocker that helps relax the uterus and stop preterm labor. Oxytocin (Choice A) is used to induce labor, not to stop preterm labor. Dinoprostone (Choice C) and Misoprostol (Choice D) are prostaglandins used to induce labor and ripen the cervix, not to stop preterm labor.

3. A nurse is preparing to administer ampicillin 500 mg in 50 ml of dextrose 5% in water (D5W) to infuse over 15 min. The drop factor of the manual IV tubing is 10 gtt/mL. How many gtt/min should the nurse set the manual IV infusion to deliver? (Round to the nearest whole number)

• A. 33 gtt/min
• B. 66 gtt/min
• C. 10 gtt/min
• D. 14 gtt/min

Correct answer: A

Rationale: To calculate the IV flow rate, you multiply the drop factor (10 gtt/mL) by the volume to be infused per minute (50 mL / 15 min). This gives you 10 gtt/mL × 50 mL / 15 min = 33.33. Rounding to the nearest whole number, the nurse should set the manual IV infusion to deliver 33 gtt/min. Choice B (66 gtt/min) is incorrect as it is the result of doubling the correct answer. Choice C (10 gtt/min) is incorrect as it only considers the drop factor without accounting for the volume to be infused. Choice D (14 gtt/min) is incorrect as it miscalculates the infusion rate based on the given information.

4. A client with a severe urinary tract infection (UTI) asks why both ciprofloxacin and phenazopyridine are needed. Which of the following responses should the nurse make?

• A. Phenazopyridine decreases adverse effects of ciprofloxacin.
• B. Combining phenazopyridine with ciprofloxacin shortens the course of therapy.
• C. The use of phenazopyridine allows for a lower dosage of ciprofloxacin.
• D. Ciprofloxacin treats the infection, and phenazopyridine treats pain.

Correct answer: D

Rationale: Ciprofloxacin is an antibiotic that treats the infection, while phenazopyridine is a urinary analgesic that relieves pain. Choice A is incorrect because phenazopyridine does not decrease adverse effects of ciprofloxacin; it primarily addresses pain. Choice B is incorrect because combining phenazopyridine with ciprofloxacin does not shorten the course of therapy; they serve different purposes. Choice C is incorrect because the use of phenazopyridine does not allow for a lower dosage of ciprofloxacin; they have independent roles in UTI management.

5. A nurse is caring for an older adult client who has a new prescription for amitriptyline to treat depression. Which of the following diagnostic tests should the nurse plan to perform prior to starting the client on this medication?

• A. Hearing examination
• B. Glucose tolerance test
• C. Electrocardiogram
• D. Pulmonary function tests

Correct answer: C

Rationale: The correct answer is C: Electrocardiogram. Amitriptyline can cause cardiac arrhythmias, so an electrocardiogram is necessary before starting treatment. A hearing examination (choice A) is not required before initiating amitriptyline. A glucose tolerance test (choice B) is not indicated for starting this medication. Pulmonary function tests (choice D) are not necessary before initiating amitriptyline for depression.
