A client with metastatic cancer of the colon experiences severe vomiting following each administration of chemotherapy. Which action, if taken by the nurse, is most appropriate?
- A. Have the patient eat large meals when nausea is not present
- B. Offer dry crackers and carbonated fluids during chemotherapy
- C. Administer prescribed antiemetics 1 hour before the treatments
- D. Give the patient two ounces of a citrus fruit beverage during treatments
Correct Answer: C
Rationale: Chemo's gut punch severe vomiting bows to preemptive antiemetics, given 1 hour before, blunting nausea's peak, the most effective move per oncology standards. Big meals overload; crackers help post-, not during; citrus risks acid reflux. Nurses time antiemetics, syncing with chemo's onslaught, a proactive strike to ease this metastatic misery, trumping reactive nibbles or sips.
Dexmedetomidine:
- A. Is recognized as an α₠receptor agonist.
- B. Increases the minimum alveolar concentration of volatile agents.
- C. Causes bradycardia.
- D. Has a loading dose of 0.5-1.0 μg kgâ»Â¹.
Correct Answer: C
Rationale: Dexmedetomidine is a highly selective α₂-adrenergic receptor agonist, not αâ‚, used for sedation with minimal respiratory depression. It reduces the minimum alveolar concentration of volatile anesthetics by enhancing sedation and analgesia, not increasing it. Bradycardia is a well-known side effect due to its sympatholytic action, decreasing heart rate via vagal stimulation and reduced catecholamine release. The standard loading dose is indeed 0.5-1.0 μg kgâ»Â¹ over 10 minutes, followed by infusion, aligning with clinical protocols. At high infusion rates, respiratory depression is unlikely, distinguishing it from opioids. Bradycardia's prominence as a side effect stems from its mechanism activation of α₂ receptors in the brainstem and periphery inhibits sympathetic outflow, making it a critical consideration in perioperative management, especially in patients with cardiovascular comorbidities.
While performing an admission assessment for a client, the nurse notes that the client has varicose veins with ulcerations and lower extremity edema with a report of a feeling of heaviness. Which of the following nursing diagnoses should the nurse identify as the priority in the client's care?
- A. Ineffective peripheral tissue perfusion
- B. Alteration in body image
- C. Impaired skin integrity
- D. Alteration in activity tolerance
Correct Answer: C
Rationale: Varicose veins with ulcerations, edema, and heaviness scream venous stasis impaired skin integrity tops the list as open sores risk infection, a pressing threat needing immediate wound care. Ineffective perfusion drives the issue, but skin breakdown's acuity trumps. Body image matters emotionally, less urgently. Activity tolerance lags behind active complications. Nurses prioritize skin integrity, addressing ulcers' vulnerability, a direct care focus to halt deterioration in this chronic venous picture, aligning with safety and healing goals.
A patient with a diagnosis of gastric cancer has been unable to tolerate oral food and fluid intake and her tumor location precludes the use of enteral feeding. What intervention should the nurse identify as best meeting this patient's nutritional needs?
- A. Administration of parenteral feeds via a peripheral IV
- B. TPN administered via a peripherally inserted central catheter
- C. Insertion of an NG tube for administration of feeds
- D. Maintaining NPO status and IV hydration until treatment completion
Correct Answer: B
Rationale: Gastric cancer blocking oral and enteral routes needs TPN via a PICC delivering calories and protein centrally, bypassing the gut. Peripheral IV can't handle TPN's osmolarity veins fry. NG's out with tumor placement. NPO with just fluids starves her long-term. Nurses in oncology peg TPN as the lifeline, keeping strength up when cancer chokes other options.
Which of the following statements is INCORRECT? The treatment of diabetes in traditional Chinese medicine involves
- A. Formula for Diabetes (Xiaoke Fang) for the Upper Type: Heat in the Lung which consumes Body Fluid
- B. Jade Maid Decoction (Yunu Jiang) for the Middle Type: excessive Heat in the Stomach
- C. Six Ingredients Rehmannia Pill (Liuwei Dihuang Wan) for the Lower Type: excessive of Kidney Yin and excessive of Yin and Yang
- D. Yam (Dioscorea opposita)
Correct Answer: C
Rationale: Traditional Chinese diabetes care Upper, Middle, Lower types nails Lung heat, Stomach fire, but Kidney's Yin deficiency, not excess Yin-Yang, flops. Xiaoke Fang, Yunu Jiang fit; Liuwei Dihuang Wan balances, doesn't overdo; yam's a lone root, not typed. Clinicians spot this, a chronic TCM misstep.
