Question 1 of 5
A nurse is reinforcing teaching with a client who reports motion sickness about using an herbal supplement. The nurse should identify that the client can use which of the following herbal supplements to help control nausea?
Correct Answer: A
Rationale: The correct answer is A: Ginger root. Ginger has been shown to be effective in reducing nausea and vomiting, making it a suitable option for controlling motion sickness. Ginger contains compounds that help to soothe the digestive system and reduce inflammation, which can alleviate symptoms of nausea. Garlic (
B) is not typically used for motion sickness and may not have the same anti-nausea properties as ginger. Kava (
C) and Valerian (
D) are not commonly used for motion sickness and do not have the same proven effectiveness as ginger.
Question 2 of 5
The nurse is discussing treatment for a superinfection with a client and family members. The family asks the nurse what a superinfection is. What is the best response by the nurse?
Correct Answer: C
Rationale: The correct answer is C: A secondary infection that occurs when microorganisms normally present in the body are killed by the drug. Superinfections occur when antibiotics disrupt the normal balance of microorganisms in the body, allowing opportunistic pathogens to thrive. This explanation clarifies the concept of superinfections in a clear and concise manner.
Choices A, B, and D are incorrect because they do not accurately define a superinfection.
Choice A focuses on treatment difficulty, choice B on immune system status, and choice D on drug resistance, which are not the defining characteristics of a superinfection.
Question 3 of 5
Which of the following differentiates a bacteriostatic drug from a bactericidal drug?
Correct Answer: B
Rationale: The correct answer is B: Bacteriostatic drugs inhibit bacterial growth, and bactericidal drugs actually kill bacteria. Bacteriostatic drugs work by stopping the growth and reproduction of bacteria, while bactericidal drugs directly kill the bacteria. This key difference in mechanism of action is what separates bacteriostatic from bactericidal drugs. Other options are incorrect because they do not accurately describe the distinction between the two types of drugs. Option A is incorrect because the spectrum of activity (narrow or broad) does not define whether a drug is bacteriostatic or bactericidal. Option C is incorrect as it confuses the mechanisms of action of the two types of drugs. Option D is incorrect as it provides an inaccurate definition of bacteriostatic and bactericidal drugs.
Question 4 of 5
A nurse is assisting with care of a client who has a prescription for 3,000 mL of intravenous fluids over the next 24 hr. The nurse should set the IV pump to deliver how many mL/hr? (Round to the nearest whole number)
Correct Answer: Rate = 3,000 mL / 24 hr = 125 mL/hr, rounded to the nearest whole number.
Rationale: The correct answer is G: 125 mL/hr.
To calculate the rate, you divide the total volume (3,000 mL) by the total time (24 hr). This gives you 125 mL/hr. Rounding to the nearest whole number, the IV pump should be set to deliver 125 mL/hr. Other choices are incorrect because they do not accurately calculate the rate based on the given information.
Choice A, B, C, D, E, and F are not the correct rate of IV fluid delivery for this specific scenario.
Question 5 of 5
A patient at a rehabilitation center is prescribed erythromycin. The nurse is reviewing the patient's medication list, checking to see if there are medications that should not be taken with this antibiotic. One medication is found. What medication should not be taken with erythromycin?
Correct Answer: C
Rationale: The correct answer is C: Lovastatin. Erythromycin can inhibit the metabolism of lovastatin, leading to increased levels of lovastatin in the body, which may result in serious side effects such as muscle pain or weakness. Ibuprofen (
A), Lasix (
B), and Lisinopril (
D) do not have significant interactions with erythromycin. Ibuprofen is a pain reliever, Lasix is a diuretic, and Lisinopril is an ACE inhibitor used for hypertension.
