A client being seen in the emergency department for complaints of chest pain confides in the nurse about regular use of cocaine as a recreational drug. The nurse takes which important action in delivering holistic nursing care to this client?
- A. Reports the client to the police for illegal drug use
- B. Explains to the client the damage that cocaine does to the heart
- C. Tells the client it is imperative to stop before myocardial infarction occurs
- D. Teaches about the effects of cocaine on the heart and offers a referral for further help
Correct Answer: D
Rationale: In this scenario, the nurse should prioritize educating the client about the effects of cocaine on the heart and provide a referral for further help. This approach is crucial in addressing the root cause of the client's health issues and supporting them in making informed decisions about their health. Reporting the client to the police or simply explaining the damage without offering solutions may not effectively address the client's needs or promote holistic care.
The client with Raynaud's phenomenon is being taught by the nurse about preventing episodes. Which instruction should the nurse reinforce?
- A. Wear gloves in cold weather.
- B. Avoid caffeine and chocolate.
- C. Increase intake of vitamin C.
- D. Use a heating pad for warmth.
Correct Answer: A
Rationale: Wearing gloves in cold weather is essential for preventing vasoconstriction and subsequent episodes of Raynaud's phenomenon. Cold temperatures can trigger vasospasms in individuals with Raynaud's, and wearing gloves helps maintain warmth and prevent the constriction of blood vessels in the extremities, reducing the likelihood of an episode.
A client is admitted with an arterial ischemic leg ulcer. The nurse expects to note that this ulcer has which typical characteristic?
- A. Dark pink base
- B. Deep and painful
- C. Accompanied by very slight pain
- D. Brown pigmentation of surrounding skin
Correct Answer: B
Rationale: Arterial ischemic ulcers are typically characterized by being deep and painful, often with a pale or necrotic base. The lack of adequate blood flow leads to tissue damage, resulting in these ulcers having a deep appearance and causing significant pain to the individual. The other options are not commonly associated with arterial ischemic ulcers; a dark pink base, very slight pain, or brown pigmentation of surrounding skin are not typical features of this type of ulcer.
