1. The healthcare provider prescribes Cytovene 375 mg every 12 hours to infuse over 90 minutes. The pharmacy delivers Cytovene 375 mg in a 150 mL IV bag. How many ml/hour should the nurse program the infusion pump?
- A. 50 ml/hour.
- B. 75 ml/hour.
- C. 100 ml/hour.
- D. 125 ml/hour.
Correct answer: C
Rationale: To infuse 150 mL over 90 minutes, the pump should be set to 100 ml/hour (150 mL / 1.5 hours). This rate ensures that the medication is delivered at the proper rate as prescribed. Choices A, B, and D are incorrect because they do not reflect the correct calculation based on the volume of the IV bag and the infusion duration provided in the question.
2. A client with diabetes mellitus is experiencing polyuria, polydipsia, and polyphagia. What do these symptoms indicate?
- A. Hypoglycemia
- B. Diabetic ketoacidosis (DKA)
- C. Hyperosmolar hyperglycemic state (HHS)
- D. Insulin shock
Correct answer: B
Rationale: Polyuria, polydipsia, and polyphagia are classic signs of diabetic ketoacidosis (DKA), which occurs due to a combination of hyperglycemia and ketone production. Hypoglycemia (Choice A) is characterized by low blood sugar levels, leading to symptoms like confusion, shakiness, and sweating, which are different from the symptoms described in the scenario. Hyperosmolar hyperglycemic state (HHS) (Choice C) typically presents with severe hyperglycemia, dehydration, and altered mental status, rather than the triad of symptoms mentioned. Insulin shock (Choice D) refers to a severe hypoglycemic reaction due to excessive insulin, manifesting with confusion, sweating, and rapid heartbeat, not the symptoms seen in the client with diabetes mellitus described in this scenario.
3. A community hit by a hurricane has suffered mass destruction and flooding. Several facilities are not functioning, and the area is contaminated with human excretions. The nurse is developing a plan of care for clients diagnosed with cholera after an outbreak. Which intervention has the highest priority?
- A. Administer prophylactic antibiotics as prescribed.
- B. Provide fluid and electrolyte replacement.
- C. Isolate all infectious diarrhea victims.
- D. Administer cholera vaccine.
Correct answer: B
Rationale: Providing fluid and electrolyte replacement is the highest priority to prevent dehydration and shock in clients with cholera. Administering prophylactic antibiotics may be necessary but is not the highest priority. Isolating infectious diarrhea victims is important for preventing the spread of infection, but addressing fluid and electrolyte imbalances takes precedence. Administering a cholera vaccine is preventive and not the immediate priority in treating clients already diagnosed with cholera.
4. A client who had a radical neck dissection returns to the surgical unit with 2 JP drains in the right side of the incision. One JP tube is open and has minimal drainage. Which action should the nurse take to increase drainage into the JP?
- A. Reinforce the incisional dressings and assess behind the neck for drainage.
- B. Place the client in a right lateral side-lying position and elevate the head of the bed.
- C. Irrigate the JP tubing with 1 ml NSS, then close the opening with its tab.
- D. Compress the bulb with the tab open and then reinsert the tab into its opening.
Correct answer: D
Rationale: Compressing the bulb with the tab open creates suction, which helps increase drainage into the JP drain. This action can aid in removing accumulated fluids from the surgical site. Reinforcing the incisional dressings and assessing behind the neck for drainage (Choice A) is not directly related to increasing drainage into the JP. Placing the client in a right lateral side-lying position and elevating the head of the bed (Choice B) may not directly impact drainage into the JP drain. Irrigating the JP tubing with 1 ml NSS and then closing the opening with its tab (Choice C) is unnecessary and could introduce contaminants into the drain.
5. A client is admitted to the emergency department with symptoms of arm numbness, chest pain, and nausea/vomiting. The examining healthcare provider believes that the client has experienced an acute myocardial infarction (AMI) within the past three hours and would like to initiate tissue plasminogen activator (tPA) therapy. Which client history findings contraindicate the use of tPA?
- A. Treats hypoglycemia with an oral hypoglycemic agent.
- B. Had a cerebrovascular hemorrhage 2 months ago.
- C. Current age 65, father died of MI at 55.
- D. Report of being intolerant of medication that contains aspirin.
Correct answer: B
Rationale: A history of cerebrovascular hemorrhage is a contraindication for tPA therapy due to the risk of bleeding. Choice A is incorrect because treating hypoglycemia with an oral hypoglycemic agent is not a contraindication for tPA therapy. Choice C is incorrect as age and family history of MI do not contraindicate the use of tPA. Choice D is incorrect as being intolerant of medication containing aspirin is not a contraindication for tPA therapy.
