Question 2 of 5
A nurse is caring for the patient post colonoscopy. The nurse reviews the medication administration record and notes a one time dose of cefazolin was given prior to the procedure. The healthcare provider then places a new order for ampicillin/sulbactam. The nurse understands that the antibiotic given prior to surgery is considered CurativeTherapeuticProphylacticDiagnosticAdjunctiveMaintenance therapy. Meanwhile the new antibiotic is used as TherapeuticProphylacticDiagnosticAdjunctiveEmpiricMaintenance therapy.
Correct Answer: C,G
Rationale: The correct answer is C: Prophylactic and G: Empiric.
Prophylactic therapy is given to prevent infection, which aligns with the one-time dose of cefazolin before colonoscopy. Empiric therapy is prescribed based on clinical judgment without definitive evidence of infection, which is the case with the new order for ampicillin/sulbactam post-procedure.
Incorrect choices:
A: Curative - Given before surgery, not to cure an existing infection.
B: Therapeutic - Not treating a diagnosed infection.
D: Diagnostic - Not used for diagnosis.
E: Adjunctive - Not used in combination with another treatment.
F: Maintenance - Not for long-term treatment.
Question 3 of 5
A nurse is caring for a client who is prescribed tetracycline 5 grams daily PO in divided doses every 8 hr. Available is tetracycline 500 mg capsules. How many capsules should the nurse administer per dose?
Correct Answer: B
Rationale: The correct answer is B: 10 capsules.
To calculate the number of capsules per dose, divide the total daily dose (5 grams) by the dose strength of each capsule (500 mg). 5 grams = 5000 mg. 5000 mg ÷ 500 mg = 10 capsules.
Therefore, the nurse should administer 10 capsules per dose to ensure the client receives the prescribed daily dose of tetracycline. Other choices are incorrect because they do not follow the correct calculation process based on the dose strength and total daily dose.
Question 4 of 5
The nurse is administering an estrogen blocker to a client diagnosed with advanced breast cancer. Which of the following side effects will the nurse caution the client regarding?
Correct Answer: C
Rationale: The correct answer is C: Thromboembolic events. Estrogen blockers can increase the risk of blood clot formation leading to thromboembolic events such as deep vein thrombosis and pulmonary embolism. The nurse should caution the client about signs and symptoms of these events like leg swelling, chest pain, and shortness of breath.
Incorrect
Choices: A: Tendon rupture is not a common side effect of estrogen blockers. B: Estrogen blockers do not increase the risk of lymphomas. D: Photosensitivity is not associated with estrogen blockers.
Question 5 of 5
A nurse is instructing a client who is newly diagnosed with pulmonary tuberculosis (TB) about the use of antitubercular medications. Which of the following information should the nurse include in the teaching?
Correct Answer: C
Rationale: The correct answer is C: A typical course of treatment involves 6 to 12 months of consistent medication use. This is because treating pulmonary TB requires a prolonged course of antibiotics to fully eradicate the bacteria. The rationale is that TB bacteria grow slowly, so a longer duration of treatment is needed to ensure all bacteria are killed.
Choice A is incorrect because TB treatment usually lasts for a specific duration, not lifelong.
Choice B is incorrect as family members are not routinely treated unless they have active TB.
Choice D is incorrect as treatment duration is not based on Mantoux test results.
