NCLEX PN Exam Cram
1. A 46-year-old has returned from a heart catheterization and wants to get up to start walking 3 hours after the procedure. The nurse should:
- A. Tell the patient to remain with the leg straight for at least another hour and check the chart for activity orders.
- B. Allow the patient to begin limited ambulation with assistance.
- C. Recommend a physical therapy consultation for ambulation.
- D. Tell the patient to remain with the leg straight for another 6 hours and check the chart for activity orders.
Correct answer: A
Rationale: The correct answer is to tell the patient to remain with the leg straight for at least another hour after a heart catheterization before starting ambulation. This period allows for proper healing and reduces the risk of complications such as bleeding or hematoma formation at the catheter insertion site. Starting ambulation too soon can disrupt the healing process and lead to adverse events. Choice B is incorrect because limited ambulation should not be initiated shortly after the procedure as it may increase the risk of complications. Choice C is incorrect as physical therapy consultation is not typically necessary for initial ambulation post-heart catheterization; this can be managed by nursing staff. Choice D is incorrect as keeping the leg straight for 6 hours is excessive and unnecessary, potentially leading to complications such as deep vein thrombosis due to prolonged immobility.
2. A client has a 10% dextrose in water IV solution running. He is scheduled to receive his antiepileptic drug, phenytoin (Dilantin), at this time. The nurse knows that the phenytoin:
- A. is given after the D10W is finished.
- B. should be given at the time it is due in the medication port closest to the client.
- C. can be piggybacked into the D10W solution now.
- D. is incompatible with dextrose solutions.
Correct answer: D
Rationale: Phenytoin is incompatible with dextrose solutions as they will precipitate when mixed together. Therefore, it should not be piggybacked into the D10W solution or given through the same port. Instead, normal saline should be used to flush before and after administering phenytoin to prevent any interaction with the dextrose solution. Delaying the administration of an antiepileptic drug like phenytoin to maintain therapeutic blood levels is not recommended, so it should not be given after the D10W is finished or based on the medication port closest to the client. Choice A is incorrect because administering phenytoin after the D10W is finished is not the correct approach due to the incompatibility with dextrose solutions. Choice B is incorrect as the timing of phenytoin administration should not be based on the medication port closest to the client but on compatibility considerations. Choice C is incorrect as piggybacking phenytoin into the D10W solution is not advisable due to the incompatibility issue.
3. A 55-year-old female asks a nurse the following, “Which mineral/vitamin is the most important to prevent the progression of osteoporosis?” The nurse should state:
- A. Potassium
- B. Magnesium
- C. Calcium
- D. Vitamin B12
Correct answer: C
Rationale: The correct answer is C: Calcium. Calcium is essential for maintaining bone health and is crucial in preventing osteoporosis. Adequate calcium intake, along with vitamin D, is vital for bone strength. While other minerals and vitamins are also important for overall health, in the context of preventing osteoporosis, calcium plays a primary role. Potassium (Choice A), Magnesium (Choice B), and Vitamin B12 (Choice D) are important for various bodily functions but are not as directly linked to preventing osteoporosis as calcium.
4. Which instruction should be given in a health education class regarding testicular cancer?
- A. All males should perform a testicular exam after a warm bath or shower.
- B. Testicular exams should be performed on a daily basis.
- C. Reddening or darkening of the scrotum is a normal finding.
- D. Testicular exams should be performed after a warm bath or shower.
Correct answer: D
Rationale: The correct instruction for testicular cancer education is that testicular exams should be performed after a warm bath or shower as it relaxes the scrotum and makes the exam easier. Testicular exams should be done monthly by all men starting around age 15, not after the age of 30 (Choice A) or on a daily basis (Choice B), which is unnecessary and may lead to unnecessary anxiety. Reddening or darkening of the scrotum is not a normal finding (Choice C) and should be reported to a healthcare provider for further evaluation.
5. Which of the following arterial blood gas values indicates a patient may be experiencing a condition of metabolic acidosis?
- A. PaO2 90 mm Hg
- B. Bicarbonate 15 mEq/L
- C. CO2 47 mm Hg
- D. pH 7.34
Correct answer: B
Rationale: The correct answer is B: Bicarbonate 15 mEq/L. In metabolic acidosis, the bicarbonate levels are lower than normal. A bicarbonate value of 15 mEq/L indicates a deficit in the buffer system, contributing to the acidosis. Choices A, C, and D are incorrect. Choice A, PaO2 90 mm Hg, reflects oxygen partial pressure and is not directly related to metabolic acidosis. Choice C, CO2 47 mm Hg, represents carbon dioxide levels and is more indicative of respiratory status. Choice D, pH 7.34, falls within the normal range (7.35-7.45) and does not confirm metabolic acidosis.
