A nurse is caring for a client who has depression and reports taking St. John's wort along with citalopram. The nurse should monitor the client for which of the following conditions as a result of an interaction between these substances?

Correct Answer: A

Rationale: The correct answer is A: Serotonin syndrome. When a client takes St. John's wort, a herbal supplement, along with citalopram, a selective serotonin reuptake inhibitor (SSRI), there is a risk of developing serotonin syndrome. Serotonin syndrome is a potentially life-threatening condition characterized by symptoms such as confusion, agitation, fever, sweating, shivering, tremors, muscle rigidity, and in severe cases, seizures and coma. It is crucial for the nurse to monitor the client for these symptoms. Choices B, C, and D are incorrect because tardive dyskinesia is associated with long-term use of antipsychotic medications, pseudo-parkinsonism is a side effect of antipsychotic medications like haloperidol, and acute dystonia is a side effect of antipsychotic medications characterized by sustained muscle contractions.

Correct Answer: A

Rationale: The correct answer is A: Pregabalin. Pregabalin is a first-line medication for treating pain in clients with fibromyalgia. It works by decreasing the number of pain signals sent out by damaged nerves. Choice B, Lorazepam, is a benzodiazepine used for anxiety and not indicated for fibromyalgia pain. Choice C, Colchicine, is used to treat gout by reducing inflammation and not indicated for fibromyalgia. Choice D, Codeine, is an opioid analgesic that is not typically recommended for fibromyalgia due to concerns about tolerance and dependence.

Correct Answer: A

Rationale: Correct answer: Applying zinc oxide ointment to the irritated area is the most appropriate action for diaper dermatitis. Zinc oxide is a barrier cream that helps protect the skin and promote healing. Choice B is incorrect because using store-bought baby wipes may contain chemicals or fragrances that can further irritate the skin. Choice C is incorrect as talcum powder can also worsen the condition by drying out the skin. Choice D is incorrect because a warm compress is not typically used for diaper dermatitis; it may provide relief for other conditions but is not the best option for diaper dermatitis.

Correct Answer: C

Rationale: The correct precaution to implement when caring for a client with Clostridium difficile infection is to wear a gown and gloves when providing care. Clostridium difficile is primarily spread through contact with feces, so wearing personal protective equipment like gowns and gloves is crucial in preventing the spread of the infection. Placing the client in a negative pressure room (Choice A) is not necessary for Clostridium difficile. While wearing an N95 respirator mask (Choice B) is important for airborne precautions, it is not required for Clostridium difficile. Placing a face mask on the client (Choice D) is not a standard precaution for preventing the spread of Clostridium difficile.

Correct Answer: D

Rationale: Urine output less than 30 mL/hr is indicative of decreased kidney function, potentially due to inadequate perfusion or other complications post-aneurysm resection. This finding requires immediate reporting to prevent further complications such as acute kidney injury. Serosanguineous drainage on the dressing, abdominal distention, and absent bowel sounds are also important postoperative assessments but are not as critical as impaired kidney function in this scenario.
