A nurse is teaching a client about cyclobenzaprinWhich of the following client statements should indicate to the nurse that the teaching about cyclobenzaprine was effective?
- A. I will have increased saliva production
- B. I will continue taking the medication until the rash disappears
- C. I will taper off the medication before discontinuing it
- D. I will report any urinary incontinence
Correct Answer: C
Rationale: Correct Answer: C. "I will taper off the medication before discontinuing it."
Rationale: Tapering off cyclobenzaprine is important to prevent withdrawal symptoms due to its muscle relaxant properties. Abruptly stopping the medication can lead to adverse effects. This statement indicates understanding of proper medication management.
Incorrect Choices:
A: Increased saliva production is not a common side effect of cyclobenzaprine.
B: Continuing the medication until the rash disappears is not relevant to cyclobenzaprine.
D: Reporting urinary incontinence is important but not specifically related to cyclobenzaprine teaching.

How many mL/h should the nurse set the IV infusion pump to deliver half the total volume of lactated Ringer's (4,080 mL) in the first 8 hours?
- A. 200 mL/h
- B. 225 mL/h
- C. 250 mL/h
- D. 255 mL/h
- E. 275 mL/h
Correct Answer: D
Rationale: The correct answer is D: 255 mL/h. To deliver half of 4,080 mL in 8 hours, you need to administer 2,040 mL in 8 hours. To calculate the infusion rate, divide the total volume by the total time: 2,040 mL ÷ 8 hours = 255 mL/h. This rate ensures half of the total volume is infused within the specified time frame.
Choice A (200 mL/h) is too slow, as it would not deliver half the volume in 8 hours. Choices B, C, and E exceed the required rate and would deliver more than half the volume in 8 hours.
Which of the following medications should the nurse anticipate administering to a client who has taken a large amount of diazepam?
- A. Ondansetron
- B. Magnesium Sulphate
- C. Flumazenil
- D. Protamine Sulphate
Correct Answer: C
Rationale: The correct answer is C: Flumazenil. Flumazenil is a benzodiazepine receptor antagonist used to reverse the effects of benzodiazepine overdose, such as diazepam. It competes with benzodiazepines at the receptor site, reversing their sedative and hypnotic effects. Ondansetron (A) is an antiemetic, Magnesium Sulphate (B) is used for various conditions like pre-eclampsia, Protamine Sulphate (D) is used to reverse heparin anticoagulation. Flumazenil is the most appropriate choice for reversing the effects of diazepam overdose.
Which of the following medications puts the client at risk for developing hearing loss?
- A. Rifampin
- B. Ciprofloxacin
- C. Penicillin G
- D. Gentamicin
Correct Answer: D
Rationale: The correct answer is D: Gentamicin. Gentamicin is an aminoglycoside antibiotic known to cause ototoxicity, leading to hearing loss. It can damage the hair cells in the inner ear, affecting hearing. Rifampin (A), Ciprofloxacin (B), and Penicillin G (C) are not associated with ototoxicity. Gentamicin should be used cautiously to prevent hearing loss.
How many mg should the nurse administer per dose to a child weighing 44 lbs if the prescribed dose is 15 mg/kg every 12 hours?
- A. 150 mg
- B. 200 mg
- C. 300 mg
- D. 350 mg
- E. 400 mg
Correct Answer: C
Rationale: To calculate the correct dose, we first convert the child's weight from pounds to kilograms (44 lbs ÷ 2.2 = 20 kg). Then, we multiply the weight by the prescribed dose (20 kg x 15 mg/kg = 300 mg). Therefore, the nurse should administer 300 mg per dose. Choice A is too low, choices B and D are higher than the correct answer, and choice E is significantly higher, exceeding the calculated dose.
A nurse is assessing a client after administering a second dose of cefazolin IV. The nurse notes the client has anxiety, hypotension, and dyspneWhich of the following medications should the nurse administer first?
- A. Diphenhydramine
- B. Albuterol inhaler
- C. Epinephrine
- D. Prednisone
Correct Answer: C
Rationale: The correct answer is C: Epinephrine. When a client exhibits symptoms of anxiety, hypotension, and dyspnea after receiving cefazolin IV, it indicates a severe allergic reaction/anaphylaxis. Epinephrine is the first-line medication for anaphylaxis as it acts quickly to reverse the symptoms by constricting blood vessels, increasing blood pressure, and opening airways. Diphenhydramine (A) is an antihistamine that can be given as a second-line treatment. Albuterol inhaler (B) is used for bronchospasm but is not the first choice in anaphylaxis. Prednisone (D) is a corticosteroid that may be used later for inflammation but is not the initial treatment for anaphylaxis.
