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)? (Select All that Apply.)
Correct Answer: A,C,F
Rationale: The correct answers are A, C, and F. A: Doxycycline may cause tooth discoloration due to deposition in developing teeth. C: Antacids can decrease doxycycline absorption. F: Doxycycline can result in photosensitivity reactions. B, D, and E are incorrect. B: Doxycycline is safe during lactation. D: Doxycycline does not typically cause hyperglycemia. E: Doxycycline can be given to pediatric patients over 8 years old.
Question 2 of 5
A client exposed to anthrax has presented to the healthcare setting. Which of the following medications below is the treatment for this biological exposure?
Correct Answer: B
Rationale: The correct answer is B: ciprofloxacin (Cipro). Anthrax is caused by Bacillus anthracis, and ciprofloxacin is an antibiotic effective against this bacterium. It inhibits bacterial DNA gyrase, leading to cell death. Nystatin (
A) is an antifungal used for Candida infections, not bacterial infections like anthrax. Metronidazole (
C) is an antibiotic used for anaerobic bacteria and protozoal infections, not anthrax. Amoxicillin/clavulanate (
D) is a broad-spectrum antibiotic but not specifically indicated for anthrax.
Question 3 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: B
Rationale:
Correct
Answer: B - This medication should be taken with a straw to avoid discoloration of the teeth.
Rationale:
1. Iron supplements can stain teeth due to their high iron content.
2. Using a straw helps bypass direct contact with teeth, reducing the risk of discoloration.
3. Antacids can decrease iron absorption, so taking iron with antacids (Option
A) is incorrect.
4. Milk contains calcium, which can inhibit iron absorption, making Option C incorrect.
5. Taking iron at night (Option
D) does not impact discoloration and is not recommended for constipation prevention.
Question 4 of 5
A client presents to the clinic with intense itching at night and diagnosed with Pinworms. The nurse anticipates the client would be placed on which medication to treat this condition?
Correct Answer: D
Rationale: The correct answer is D: mebendazole (Vermox). Mebendazole is an anthelmintic medication commonly used to treat pinworm infections. It works by preventing the worms from absorbing sugars essential for their survival, ultimately leading to their death. Zidovudine (Retrovir) is an antiretroviral drug used to treat HIV, not pinworms. Ketoconazole (Nizoral) is an antifungal medication used to treat fungal infections, not pinworms. Metronidazole (Flagyl) is an antibiotic used to treat bacterial and parasitic infections, but it is not typically used for pinworms. In summary, mebendazole is the appropriate choice for treating pinworms due to its specific mechanism of action against these parasites, making it the correct answer.
Question 5 of 5
A client with a organ transplant has been placed on methotrexate (Rheumatrex). Which of the following mechanism of actions below describes this medication?
Correct Answer: B
Rationale: The correct answer is B: Inhibits replication by blocking folic acid synthesis. Methotrexate works by inhibiting dihydrofolate reductase, an enzyme involved in the synthesis of folic acid, which is essential for DNA replication. By blocking this enzyme, methotrexate interferes with the production of DNA and RNA, leading to the suppression of cell proliferation. This mechanism makes it effective in treating conditions like autoimmune diseases and cancer.
Choices A, C, and D are incorrect because methotrexate does not directly target helper T cells, prevent DNA and RNA synthesis, or act as an estrogen blocker.
