Question 1 of 5
A nurse is caring for a client recently prescribed doxycycline (Doryx) for the treatment of a urinary tract infection. Which of the following statements below applies to doxycycline (Doryx)?
Correct Answer: A,C,D,E
Rationale: The correct answer is A, C, D, and E. A: Doxycycline should not be taken if lactating as it can pass into breast milk. C: Doxycycline may cause photosensitivity, increasing the risk of sunburn. D: Doxycycline should not be taken with antacids as they can reduce its absorption. E: Doxycycline may cause discoloration of the teeth, especially in children under 8 years old. These statements are accurate based on doxycycline's pharmacological properties and potential side effects.
Choices B, F, and G are incorrect as hyperglycemia is not a common side effect of doxycycline and options F and G are not applicable.
Question 2 of 5
A client recently diagnosed with Iron deficiency Anemia is prescribed Ferrous Sulfate daily. Which of the following statements below is true regarding iron therapy?
Correct Answer: A
Rationale: The correct answer is A: This medication should be taken with a straw to avoid discoloration of the teeth. Iron supplements can cause teeth staining, so using a straw can help bypass direct contact with teeth.
Choice B is incorrect because timing of iron intake does not affect constipation.
Choice C is incorrect as antacids can interfere with iron absorption.
Choice D is incorrect as milk can inhibit iron absorption due to calcium content.
Question 3 of 5
2-month-old patient with current active infection. Being treated with neomycin. The nurse understands that neomycin may cause serious adverse effects such as
Correct Answer: A,F
Rationale: The correct answers are A and F. Neomycin is known to cause ototoxicity, which can result in hearing loss and balance issues. It can also lead to pseudomembranous colitis, a severe inflammation of the colon. Ototoxicity can occur due to neomycin's effects on the inner ear, while pseudomembranous colitis is a known side effect due to disruption of normal gut flora.
Choices B, C, D, E, and G are incorrect because neomycin is not associated with constipation, hypercalcemia, thrombocytopenia, hypotrichosis, or photosensitivity. It is crucial for the nurse to monitor the patient for signs and symptoms of ototoxicity and pseudomembranous colitis while on neomycin therapy.
Question 4 of 5
A client diagnosed with strep throat requires antibiotics for treatment. With an allergy to penicillin, the nurse understands which medication should be avoided due to cross-sensitivity with penicillin medications?
Correct Answer: D
Rationale: The correct answer is D: Cephalosporins. Cephalosporins share a similar beta-lactam ring structure with penicillins, leading to potential cross-reactivity in patients with penicillin allergies. Macrolides (
A), antiretrovirals (
B), and antimalarials (
C) do not have this structural similarity, so they are safe alternatives for patients allergic to penicillin. In summary, choosing cephalosporins for a patient with a penicillin allergy can lead to an allergic reaction due to cross-sensitivity, making it an inappropriate choice in this scenario.
Question 5 of 5
A client diagnosed with trichomoniasis is prescribed metronidazole. The nurse should instruct the client to avoid which contraindication associated with this medication?
Correct Answer: A
Rationale: The correct answer is A: Alcohol consumption. Metronidazole interacts with alcohol, causing a disulfiram-like reaction characterized by nausea, vomiting, flushing, and headache. This is due to the inhibition of acetaldehyde dehydrogenase, leading to accumulation of acetaldehyde. Tyramine-based foods, apple juice, and soybeans do not have significant interactions with metronidazole. It is important to avoid alcohol consumption to prevent adverse reactions.
