NCLEX PN Exam Cram
1. The PN is caring for a client with diabetes insipidus. The nurse can expect the lab work to show:
- A. elevated urine osmolarity and elevated serum osmolarity.
- B. decreased urine osmolarity and decreased serum osmolarity.
- C. elevated urine osmolarity and decreased serum osmolarity.
- D. decreased urine osmolarity and elevated serum osmolarity.
Correct answer: D
Rationale: In diabetes insipidus, the pituitary releases too much antidiuretic hormone (ADH), causing the client to produce a large amount of dilute urine (decreased osmolarity) and leading to dehydration (elevated serum osmolarity). Therefore, the correct answer is decreased urine osmolarity and elevated serum osmolarity. Choice C, elevated urine osmolarity and decreased serum osmolarity, is incorrect for diabetes insipidus, as it is more characteristic of syndrome of inappropriate ADH (SIADH). Choices A and B, elevated urine osmolarity and elevated serum osmolarity, and decreased urine osmolarity and decreased serum osmolarity, respectively, are generally not seen in diabetes insipidus, as urine and serum osmolarity typically move in opposite directions in this condition.
2. The nurse is providing post-operative care to the craniotomy client. Diabetes insipidus is suspected when the client's urine output suddenly increases significantly. Which action takes highest priority?
- A. Continue to monitor urine output
- B. Check a pulse
- C. Check a blood pressure
- D. Check level of consciousness (LOC)
Correct answer: C
Rationale: The correct answer is to check a blood pressure. Diabetes insipidus can lead to dehydration and potential hypovolemic shock due to excessive urine output. Monitoring blood pressure is crucial to assess the client's circulatory status and detect signs of shock early. Checking the blood pressure will provide essential information on perfusion, which is vital in this situation. Continuing to monitor urine output, checking a pulse, or assessing the level of consciousness are important but not as high a priority as evaluating the blood pressure in a potentially critical situation like suspected diabetes insipidus.
3. A client newly diagnosed with Diabetes Mellitus needs education. Which of the following statements should the nurse include in this education?
- A. "You can eat anything you want, but avoid foods with sugar."?
- B. "You need to lose weight, so your diet must be controlled."?
- C. "You need a diet and exercise program."?
- D. "You must reduce salt, fat, and sugar intake in your diet."?
Correct answer: C
Rationale: A client newly diagnosed with Diabetes Mellitus requires education on managing their condition. Choice C is the correct answer because it emphasizes the importance of a comprehensive approach involving both diet and exercise. This holistic approach is crucial in managing blood sugar levels and overall health for individuals with diabetes. Choice A is incorrect as it provides misleading information by suggesting that the client can eat anything as long as it doesn't contain sugar, which is not accurate for diabetes management. Choice B is not the best option as it focuses solely on weight loss rather than addressing the holistic needs of a diabetic individual. Choice D is incorrect as it suggests eliminating all salt, fat, and sugar, which is an extreme approach and not a realistic or balanced way to manage diabetes.
4. Which client should the nurse see first?
- A. Recurring crushing chest pain
- B. Needing an IV for surgery in 5 minutes
- C. Needing PCA morphine for pain control post-hysterectomy
- D. Waiting to get back to bed after sitting in a chair for 30 minutes
Correct answer: A
Rationale: The client presenting with recurring crushing chest pain should be seen first as this symptom could indicate a myocardial infarction (MI), which is a life-threatening condition requiring immediate attention. Assessing and managing potential cardiac issues take priority over other concerns like needing an IV for surgery, pain control post-hysterectomy, or assistance with mobility. While all clients require care, addressing the chest pain promptly is crucial to ensure the client's safety and well-being.
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.
