NCLEX PN Exam Cram
1. A nurse working in a surgical unit notices a patient experiencing SOB, calf pain, and warmth over the posterior calf. All of these symptoms may indicate which of the following medical conditions?
- A. Patient may have a DVT.
- B. Patient may be exhibiting signs of dermatitis.
- C. Patient may be in the late stages of CHF.
- D. Patient may be experiencing anxiety after surgery.
Correct answer: A
Rationale: The correct answer is that the patient may have a DVT (Deep Vein Thrombosis). SOB (Shortness of Breath), calf pain, and warmth over the posterior calf are classic signs and symptoms of DVT. DVT is a serious condition where a blood clot forms in a deep vein, commonly in the legs. Choices B, C, and D are incorrect because dermatitis does not typically present with these symptoms, late stages of CHF would manifest with other signs, and anxiety after surgery usually does not produce these specific symptoms.
2. Teaching about the need to avoid foods high in potassium is most important for which client?
- A. a client receiving diuretic therapy
- B. a client with an ileostomy
- C. a client with metabolic alkalosis
- D. a client with renal disease
Correct answer: D
Rationale: Clients with renal disease are predisposed to hyperkalemia and should avoid foods high in potassium. High potassium levels can further burden the kidneys and worsen the condition. Choices A, B, and C are incorrect because clients receiving diuretic therapy, with an ileostomy, or with metabolic alkalosis are at risk for hypokalemia, which is low potassium levels. Therefore, these clients should actually be encouraged to eat foods high in potassium to maintain adequate levels and prevent complications associated with hypokalemia.
3. Metformin (Glucophage) is administered to clients with type II diabetes mellitus. Metformin is an example of:
- A. an antihyperglycemic agent.
- B. a hypoglycemic agent.
- C. an insulin analogue.
- D. a pancreatic alpha cell stimulant
Correct answer: A
Rationale: Metformin is classified as an antihyperglycemic agent because it works by reducing hepatic glucose output and decreasing glucose absorption from the gut, thereby preventing hyperglycemia. Choice B, a hypoglycemic agent, is incorrect as hypoglycemic agents stimulate insulin production, which is not the mechanism of action of metformin. Choice C, an insulin analogue, is incorrect as metformin is not a type of insulin but a distinct medication. Choice D, a pancreatic alpha cell stimulant, is incorrect as metformin does not stimulate any pancreatic cells, but rather acts on the liver and gut to lower blood sugar levels.
4. Which of the following medications is a serotonin antagonist that might be used to relieve nausea and vomiting?
- A. metoclopramide (Reglan)
- B. ondansetron (Zofran)
- C. hydroxyzine (Vistaril)
- D. prochlorperazine (Compazine)
Correct answer: B
Rationale: Zofran is a serotonin antagonist commonly used to relieve nausea and vomiting by blocking serotonin receptors. Metoclopramide (Reglan) acts on dopamine receptors, hydroxyzine (Vistaril) is an antihistamine, and prochlorperazine (Compazine) is a dopamine antagonist. While these medications can also be used for nausea and vomiting, they do not primarily function as serotonin antagonists like ondansetron.
5. A nurse is assigned to do pre-operative teaching on a blind patient who is scheduled for surgery the following morning. What teaching strategy would best fit the situation?
- A. Verbal teaching in short sessions throughout the day
- B. Provide a pre-operative booklet in Braille
- C. Provide an audio recording for the client
- D. Have the blind patient's family member assist with the instruction
Correct answer: A
Rationale: For a blind patient scheduled for surgery the following morning, the best teaching strategy would be verbal teaching in short sessions throughout the day. Providing information in smaller amounts makes it easier to retain, and one-on-one teaching is most effective. Choice B, providing a pre-operative booklet in Braille, may not be as practical for last-minute teaching. Choice C, providing an audio recording, may not allow for immediate interaction and clarification. Choice D, having a family member instruct the patient, may not ensure the accuracy and clarity of the information provided.
