The patient should be taught that an improvement in symptoms will likely be noticed within
- A. 48 hours.
- B. a week to 10 days.
- C. 2 to 3 weeks.
- D. 4 to 6 weeks.
Correct Answer: C
Rationale: When taking isoniazid and rifampin for active tuberculosis, patients should be taught that an improvement in symptoms will likely be noticed within 2 to 3 weeks. Choice A (48 hours) is too soon to expect significant improvement in symptoms. Choice B (a week to 10 days) is also too early for noticeable improvement with this medication regimen. Choice D (4 to 6 weeks) is too far out to expect a noticeable improvement in symptoms.

A patient's antiretroviral therapy has not been as efficacious as her care team had predicted, and maraviroc (Selzentry) has consequently been added to her drug regimen. The nurse should recognize this drug as belonging to what category of antiretroviral?
- A. Fusion protein inhibitors
- B. Protease inhibitors
- C. CCR5 antagonists
- D. Integrase strand transfer inhibitors

Which patient is most likely to be diagnosed with complex regional pain syndrome II (CRPS II)?
- A. A patient who has experienced a spinal cord injury and reports severe, burning pain in his legs.
- B. A patient who reports severe pain in her hand following a surgery for carpal tunnel syndrome.
- C. A patient who develops pain in his foot following a fracture and immobilization with a cast.
- D. A patient who experiences chronic pain and swelling in his arm following a brachial plexus injury.
Correct Answer: D
Rationale: Complex regional pain syndrome II (CRPS II) typically occurs after an injury to a peripheral nerve. In this case, a brachial plexus injury involves damage to the nerves that control muscles in the arm and hand, leading to chronic pain and swelling. Choices A, B, and C describe pain related to other conditions such as spinal cord injury, carpal tunnel surgery, and fracture immobilization, which are not typically associated with CRPS II.
A patient who was frequently homeless over the past several years has begun a drug regimen consisting solely of isoniazid (INH). What is this patient's most likely diagnosis?
- A. Active tuberculosis
- B. Latent tuberculosis
- C. Mycobacterium avium complex
- D. Human immunodeficiency virus
Correct Answer: A
Rationale: The correct answer is A: Active tuberculosis. Given the patient's history of homelessness and initiation of isoniazid (INH) treatment, the most likely diagnosis is active tuberculosis. Isoniazid is a first-line medication used in the treatment of active tuberculosis. Latent tuberculosis (choice B) would not typically necessitate treatment with isoniazid alone. Mycobacterium avium complex (choice C) is not typically treated with isoniazid alone. Human immunodeficiency virus (choice D) is a risk factor for developing tuberculosis but is not the primary diagnosis in this patient scenario.
When administering an immunization, which of the following medications should be available?
- A. Diphenhydramine (Benadryl)
- B. Hydroxyzine (Vistaril)
- C. Physostigmine
- D. Epinephrine
Correct Answer: D
Rationale: When administering an immunization, it is essential to have epinephrine available in case of an allergic reaction such as anaphylaxis. Epinephrine is the medication of choice for treating severe allergic reactions due to its ability to reverse the symptoms rapidly. Diphenhydramine and hydroxyzine are antihistamines that can help manage mild allergic reactions but are not the primary medications for severe reactions like anaphylaxis. Physostigmine is not indicated for managing allergic reactions and is used for specific conditions such as anticholinergic toxicity.
A nurse practitioner is assessing a 7-year-old boy who has been brought to the clinic by his mother, who is concerned about her son's increasingly frequent, severe headaches. Which of the nurse's questions is least likely to yield data that will confirm or rule out migraines as the cause of his problem?
- A. Does your son have a family history of migraines?
- B. When your son has a headache, does he ever have nausea and vomiting as well?
- C. Does your son have any food allergies that have been identified?
- D. Is your son generally pain-free during the intervals between headaches?
Correct Answer: C
Rationale: The correct answer is C. In assessing a child for migraines, asking about food allergies is least likely to yield data that will confirm or rule out migraines as the cause of his headaches. Food allergies are unrelated to the typical symptoms and triggers of migraines, such as family history, associated symptoms like nausea and vomiting, and pain-free intervals between headaches. Therefore, in this scenario, focusing on food allergies is less relevant for identifying migraines as the cause of the boy's headaches.
