NCLEX PN Exam Cram
1. A 15-year-old high school wrestler has been taking diuretics to lose weight to compete in a lower weight class. Which of the following medical tests is most likely to be given?
- A. Lab values of Potassium and Sodium
- B. Lab values of Glucose and Hemoglobin
- C. ECG
- D. CT scan
Correct answer: A
Rationale: Diuretics can disrupt the sodium and potassium balance, potentially leading to cardiac complications. Monitoring the lab values of potassium and sodium is crucial to assess electrolyte imbalances due to diuretic use. Testing glucose and hemoglobin levels is not directly related to diuretic use in this context. An ECG would be indicated if there were signs or symptoms of cardiac abnormalities, but it is not the primary test to monitor the effects of diuretics. A CT scan is not typically used to assess electrolyte imbalances caused by diuretics.
2. A patient has recently been prescribed Zidovudine (Retrovir). The patient has AIDS. Which of the following side effects should the patient specifically watch out for?
- A. Weakness and SOB
- B. Fever and anemia
- C. Hypertension and SOB
- D. Fever and hypertension
Correct answer: B
Rationale: The correct answer is 'Fever and anemia.' Zidovudine (Retrovir) is known to cause anemia as a side effect due to its impact on the bone marrow. Fever is also a common side effect associated with Zidovudine use. Therefore, the patient should watch out for these specific side effects. Choice A (Weakness and SOB) is incorrect as shortness of breath (SOB) is not a commonly reported side effect of Zidovudine. Choice C (Hypertension and SOB) and Choice D (Fever and hypertension) are unrelated to the known side effects of Zidovudine, making them incorrect.
3. A client receives a cervical intracavity radium implant as part of her therapy. A common side effect of a cervical implant is:
- A. creamy, pink-tinged vaginal drainage.
- B. stomatitis.
- C. constipation.
- D. xerostomia.
Correct answer: A
Rationale: The correct answer is 'creamy, pink-tinged vaginal drainage.' This side effect persists for 1 to 2 months after the removal of a cervical implant. Diarrhea, not constipation, is usually a side effect of cervical implants. Stomatitis and xerostomia are local side effects of radiation to the mouth, not associated with cervical implants. Therefore, choices B, C, and D are incorrect.
4. The nurse is caring for a client admitted with Class III/IV Pulmonary Hypertension. The nurse explains to the client that Lanoxin is being administered to the client in order to:
- A. Manage peripheral edema
- B. Improve right ventricular function
- C. Increase pulmonary pressure
- D. Constrict the pulmonary vessels
Correct answer: B
Rationale: The correct answer is to improve right ventricular function. Lanoxin, also known as digoxin, is a cardiac glycoside that works by slowing the heart rate and increasing myocardial contractility, especially in the ventricles. This action helps improve the efficiency of the heart's pumping function, particularly the right ventricle in conditions like pulmonary hypertension. Choice A, managing peripheral edema, is not directly related to Lanoxin's mechanism of action. Choice C, increasing pulmonary pressure, is incorrect as Lanoxin is not used to increase pressure in the pulmonary circulation. Choice D, constricting the pulmonary vessels, is incorrect as Lanoxin does not cause vasoconstriction in the pulmonary vessels but rather acts on the heart's contractility.
5. What are the major electrolytes in the extracellular fluid?
- A. potassium and chloride
- B. potassium and phosphate
- C. sodium and chloride
- D. sodium and phosphate
Correct answer: C
Rationale: The correct answer is sodium and chloride. These two electrolytes are the major components of extracellular fluid. Potassium and phosphate (Choice B) are not the major electrolytes in the extracellular fluid. Potassium is primarily an intracellular ion, and phosphate is more abundant in the intracellular fluid and bones. Sodium and phosphate (Choice D) are also not the major electrolytes in the extracellular fluid. Chloride plays a crucial role in maintaining electrolyte balance and is predominantly found in extracellular fluid alongside sodium.
