A client has been taking a drug (Drug A) that is highly metabolized by the cytochrome P-450 system. He has been on this medication for 6 months. At this time, he is started on a second medication (Drug B) that is an inducer of the cytochrome P-450 system. You should monitor this client for:
- A. increased therapeutic effects of Drug A.
- B. increased adverse effects of Drug B.
- C. decreased therapeutic effects of Drug A.
- D. decreased therapeutic effects of Drug B.
Correct Answer: C
Rationale: When a client is taking a drug (Drug A) metabolized by the cytochrome P-450 system and is then started on another drug (Drug B) that induces this system, the metabolism of Drug A is increased. This results in decreased therapeutic effects of Drug A as it is broken down more rapidly. Monitoring is required to address potential reduced efficacy. The therapeutic effect of Drug A is diminished, not enhanced. Inducing the cytochrome P-450 system does not directly increase the adverse effects of Drug B. Although Drug B is an inducer, its therapeutic effects are not decreased as it is not metabolized faster.

How can the nurse promote relief of muscle pain, spasms, and tension?
- A. Encouraging the client to continue their activities as usual.
- B. Immobilizing the client.
- C. Applying heat, cold, pressure, or vibration to the painful area.
- D. Administering pain medication as needed to ease the muscle.
Correct Answer: C
Rationale: To promote relief of muscle pain, spasms, and tension, the nurse should consider applying heat, cold, pressure, or vibration to the painful area. These interventions can help alleviate pain associated with muscle tension, pain, or spasms. Choice A is incorrect because encouraging the client to continue their activities as usual may exacerbate the pain. Choice B is incorrect as immobilizing the client may not address the underlying issue and could potentially lead to further complications. Choice D is also incorrect because while pain medication can be used, it is not the first-line treatment for muscle pain, spasms, and tension.
A patient has been diagnosed with Guillain-Barre Syndrome. Which of the following statements is the most applicable when discussing the impairments with Guillain-Barre Syndrome with the patient?
- A. Guillain-Barre Syndrome improves in almost all cases within 5 years.
- B. Guillain-Barre Syndrome causes limited sensation in the abdominal region.
- C. Guillain-Barre Syndrome causes muscle weakness in the legs.
- D. Guillain-Barre Syndrome affects breathing in severe cases.
Correct Answer: C
Rationale: The correct statement is that Guillain-Barre Syndrome causes muscle weakness in the legs. This muscle weakness typically starts in the legs and can progress to the upper body. Choice A is incorrect as while most cases do improve, the recovery time can vary. Choice B is incorrect as Guillain-Barre Syndrome primarily affects muscle weakness rather than sensation. Choice D is incorrect as severe cases of Guillain-Barre Syndrome can lead to respiratory muscle weakness, impacting breathing.
A violation of a patient's confidentiality occurs if two nurses are discussing client information in which of the following scenarios?
- A. With a physical therapist treating the patient
- B. With a social worker planning for discharge
- C. With another nurse on duty to plan for break time
- D. In the hallway outside the patient's room
Correct Answer: D
Rationale: The correct answer is 'In the hallway outside the patient's room.' Discussing client information in a public area like a hallway can potentially breach patient confidentiality as it increases the risk of unauthorized individuals overhearing sensitive information. Choices A, B, and C involve discussing client information with other healthcare professionals in appropriate settings, which are more likely to maintain patient confidentiality compared to discussing in a public space like a hallway. Option D is the correct choice because it highlights a scenario where patient information is at higher risk of exposure to unauthorized individuals, hence violating patient confidentiality.
What is the most effective strategy to assist a client in recognizing and using personal strength?
- A. Encouraging the client's self-identification of strengths.
- B. Promoting the client's active external thinking.
- C. Listening to the client and providing advice as needed.
- D. Assisting the client in maintaining an external locus of control.
Correct Answer: A
Rationale: Encouraging the client to identify their own strengths is empowering and helps build self-awareness and self-confidence. This strategy promotes autonomy and self-efficacy, enabling the client to recognize and utilize their personal strengths effectively. Option B, promoting the client's active external thinking, is vague and not directly related to recognizing personal strengths. Option C, listening to the client and providing advice as needed, focuses more on the nurse's role rather than empowering the client to recognize their strengths independently. Option D, assisting the client in maintaining an external locus of control, goes against the goal of helping the client recognize and utilize their internal strengths.
Which of the following injuries, if demonstrated by a client entering the Emergency Department, is the highest priority?
- A. open leg fracture
- B. open head injury
- C. stab wound to the chest
- D. traumatic amputation of a thumb
Correct Answer: C
Rationale: A stab wound to the chest might result in lung collapse and mediastinal shift that, if untreated, could lead to death. Treatment of an obstructed airway or a chest wound is a higher priority than hemorrhage. The principle of ABC (airway, breathing, and circulation) prioritizes care decisions. In this scenario, the stab wound to the chest poses the highest risk to the client's life as it can lead to severe complications such as lung collapse and mediastinal shift. Addressing this injury promptly is crucial to prevent further harm or potential fatality. Open leg fracture, open head injury, and traumatic amputation of a thumb, while serious, do not pose an immediate life-threatening risk compared to a stab wound to the chest.
