Question 1 of 5
The nurse is instructing a client who has been prescribed tetracycline (Sumycin). What should the nurse advise this client to avoid while taking this medication?
Correct Answer: B
Rationale: The correct answer is B: Sunlight. Tetracycline can cause photosensitivity, leading to severe sunburns and skin damage. The nurse should advise the client to avoid prolonged exposure to sunlight and to use sunscreen. Green leafy vegetables (
A), exercise (
C), and foods high in tyramine (
D) are not contraindicated with tetracycline. Green leafy vegetables are a good source of nutrients, exercise is beneficial for overall health, and tyramine-rich foods are typically avoided with other medications like MAOIs.
Question 2 of 5
Which of the following drugs inhibit bacterial beta-lactamase?
Correct Answer: D
Rationale: The correct answer is D: Zosyn (piperacillin/tazobactam). Piperacillin is a beta-lactam antibiotic susceptible to beta-lactamase degradation. Tazobactam is a beta-lactamase inhibitor that protects piperacillin from degradation, enhancing its antibacterial activity. Goldenseal (
A) is an herb with no known beta-lactamase inhibitory properties. Ceftriaxone (
B) and Penicillin (
C) are beta-lactam antibiotics but do not inhibit beta-lactamase.
Question 3 of 5
The nurse understands that CAM therapies have common characteristics, such as which of the following? (Select All that Apply)
Correct Answer: A,B,D
Rationale: The correct answer is A, B, and D. A - CAM therapies often recognize the role of spirituality in health and healing, promoting holistic well-being. B - They focus on treating the individual as a whole person, considering physical, emotional, and spiritual aspects. D - CAM therapies promote disease prevention, self-care, and self-healing, empowering individuals to take control of their health.
Choices C, E, F, and G are incorrect because CAM therapies do not solely focus on physical health; they encompass a holistic approach that addresses various aspects of an individual's well-being.
Question 4 of 5
The nurse is asked why neomycin is given as a bowel prep before GI surgery. The nurse correctly replies that:
Correct Answer: B
Rationale: The correct answer is B. Neomycin is given as a bowel prep before GI surgery to reduce intestinal bacteria, which lowers the risk of postoperative infections. This is important because the presence of bacteria in the intestines can lead to complications such as peritonitis or wound infections. By decreasing the bacterial load in the bowel before surgery, the likelihood of these complications occurring is minimized.
Choice A is incorrect because starting antibiotic therapy 4 days before surgery is not specifically related to neomycin as a bowel prep.
Choice C is incorrect as bacteria in the bowel can be reduced with the use of antibiotics.
Choice D is incorrect because anesthesia does not make the bowel resistant to antibiotics.
Question 5 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 mL
Rationale: The correct answer is 0.6 mL.
To calculate this, divide the dose needed (3 mg) by the concentration of the medication (5 mg/mL). 3 mg / 5 mg/mL = 0.6 mL. This calculation ensures the nurse administers the correct amount of medication. Other choices are incorrect because they do not reflect the accurate calculation based on the given dose and concentration. For example, selecting a higher volume would result in administering more medication than prescribed, potentially leading to overdose, while choosing a lower volume would result in underdosing the patient. The correct answer of 0.6 mL aligns with safe medication administration principles.
