Acyclovir is the drug of choice for which condition?
- A. HIV
- B. HSV 1 and 2 and VZV
- C. CMV
- D. influenza A viruses
Correct Answer: B
Rationale: Acyclovir is a nucleoside analog antiviral drug that is specifically effective against herpes simplex virus (HSV) types 1 and 2, as well as varicella-zoster virus (VZV). The drug works by inhibiting viral DNA synthesis. HSV and VZV are both members of the herpes virus family, and acyclovir is most commonly prescribed for infections caused by these viruses. Therefore, the correct answer is B.
Choice A (HIV) is incorrect because acyclovir is not effective against HIV. Choice C (CMV) is incorrect because acyclovir is less effective against cytomegalovirus (CMV) compared to HSV and VZV. Choice D (influenza A viruses) is incorrect because acyclovir is not indicated for the treatment of influenza viruses.

A 59-year-old patient tells the nurse that he is in the clinic to "check up on his ulcerative colitis." He has been having "black stools" in the last 24 hours. How would the nurse document his reason for seeking care?
- A. J.M. is a 59-year-old male here for "ulcerative colitis."
- B. J.M. came into the clinic complaining of black stools in the past 24 hours.
- C. J.M., a 59-year-old male, states he has ulcerative colitis and wants to have it checked up.
- D. J.M. is a 59-year-old male here for having "black stools" in the past 24 hours.
Correct Answer: D
Rationale: The correct answer is D because it accurately reflects the patient's chief complaint of having black stools in the last 24 hours, which is a concerning symptom suggestive of gastrointestinal bleeding. This documentation is specific and focused on the reason for seeking care, prioritizing the urgent nature of the symptom.
Choice A is incorrect because it does not mention the presenting symptom of black stools. Choice B is incorrect as it does not directly state the reason for seeking care. Choice C is incorrect as it focuses on the patient's self-diagnosis of ulcerative colitis rather than the current concerning symptom of black stools.
What instructions should the nurse give to a client undergoing mammography?
- A. Be sure to use underarm deodorant
- B. Do not use underarm deodorant
- C. Do not eat or drink after midnight
- D. Have a friend drive you home
Correct Answer: B
Rationale: The correct answer is B: Do not use underarm deodorant. This is important because deodorant can interfere with the mammogram results, leading to false readings. It is crucial to have a clean and uncontaminated image for an accurate diagnosis. Choice A is incorrect as it can affect the quality of the mammogram. Choices C and D are irrelevant to the mammography procedure and not necessary instructions for the client.

1. Collecting a follow-up database ensures up-to-date information.
2. It allows for monitoring of medication effectiveness and any new symptoms.
3. Checking the blood pressure is essential but needs current context.
4. Asking the patient to read her record may not provide all necessary updates.
5. The complete health history is crucial but obtaining it first may delay urgent blood pressure check.

- A. Use medical jargon to explain the procedure to ensure the patient understands.
- B. Speak loudly and slowly to make sure the patient understands.
- C. Use a professional interpreter or translation services to communicate effectively.
- D. Ask the patient's family to translate for the nurse.

Professional interpreters are trained to accurately convey information while respecting cultural nuances.
Explanation for why the other choices are incorrect:
A: Using medical jargon can confuse the patient further and hinder effective communication.
B: Speaking loudly and slowly can come across as patronizing and does not address the language barrier.

What should be the nurse's first action when caring for a client who has a suspected stroke?
- A. Assess the client's airway
- B. Administer oxygen
- C. Administer aspirin
- D. Perform a CT scan
Correct Answer: A
Rationale: The correct answer is A: Assess the client's airway. This is the first action because airway patency is the top priority in any emergency situation, including a suspected stroke. Ensuring the client can breathe effectively is crucial to prevent hypoxia and further complications. Administering oxygen (choice B) may be necessary after assessing the airway. Administering aspirin (choice C) should be done after a definitive diagnosis of an ischemic stroke. Performing a CT scan (choice D) is important for diagnosis but is not the first action to take in a suspected stroke scenario.
