HESI 799 RN Exit Exam
1. A client with chronic kidney disease (CKD) is scheduled for hemodialysis. Which laboratory value should the nurse report to the healthcare provider before the procedure?
- A. Serum potassium of 5.5 mEq/L
- B. Hemoglobin of 10 g/dl
- C. Potassium of 6.0 mEq/L
- D. Blood glucose of 200 mg/dl
Correct answer: C
Rationale: The correct answer is C: Potassium of 6.0 mEq/L. A potassium level of 6.0 mEq/L is dangerously high in a client with CKD, and it should be reported before hemodialysis to prevent cardiac complications. High potassium levels can lead to life-threatening arrhythmias. Choices A, B, and D are not the most critical values to report before hemodialysis. While a serum potassium level of 5.5 mEq/L is slightly elevated, it is not as urgent as a level of 6.0 mEq/L in this context. Hemoglobin of 10 g/dl and blood glucose of 200 mg/dl are important parameters to monitor but are not as immediately concerning before hemodialysis compared to a high potassium level.
2. How can a nurse best help a client undergoing a bone marrow aspiration and biopsy, along with two upset family members, manage anxiety during the procedure?
- A. Allow the client's family to stay for emotional support.
- B. Accompany the client silently.
- C. Encourage the client to take slow, deep breaths to promote relaxation.
- D. Provide the client an opportunity to verbalize emotions.
Correct answer: C
Rationale: Encouraging the client to take slow, deep breaths is an effective way for the nurse to help the client manage anxiety during the bone marrow aspiration and biopsy procedure. Slow, deep breathing can promote relaxation and help reduce anxiety levels. Choice A, allowing the client's family to stay for emotional support, may provide comfort but does not address a direct intervention to help manage anxiety. Choice B, staying with the client silently, may not actively help the client address their anxiety. Choice D, allowing the client to express feelings, is important but may not directly address anxiety management during the procedure.
3. Which dietary instruction is most important for a client with renal disease?
- A. Avoid all protein-rich foods.
- B. Limit fluid intake to 1500 ml/day.
- C. Increase potassium intake to prevent weakness.
- D. Eat small, frequent meals high in carbohydrates.
Correct answer: B
Rationale: The most important dietary instruction for a client with renal disease is to limit fluid intake to 1500 ml/day. This is essential to prevent fluid overload, manage electrolyte balance, and reduce strain on the kidneys. Choice A is incorrect because while protein restriction may be necessary in some cases, avoiding all protein-rich foods is not recommended as some protein intake is essential for overall health. Choice C is incorrect because increasing potassium intake is generally not advised for clients with renal disease, as they often need to limit potassium intake. Choice D is also incorrect because while consuming small, frequent meals may be helpful, emphasizing a diet high in carbohydrates is not typically the primary focus for clients with renal disease.
4. What is the primary method of asexual reproduction used by most bacteria?
- A. Meiosis
- B. Mitosis
- C. Binary fission
- D. Interphase
Correct answer: C
Rationale: The correct answer is C: Binary fission. This is the main process through which most bacteria reproduce asexually. During binary fission, a single cell divides into two identical cells, each containing a copy of the genetic material. Choices A and B, meiosis and mitosis, are processes involved in sexual reproduction and are not used by bacteria for asexual reproduction. Choice D, interphase, is a stage of the cell cycle where the cell prepares for division and is not a method of reproduction.
5. When should the LPN/LVN encourage the laboring client to begin pushing?
- A. When there is only an anterior or posterior lip of the cervix left.
- B. When the client describes the need to have a bowel movement.
- C. When the cervix is completely dilated.
- D. When the cervix is completely effaced.
Correct answer: C
Rationale: The LPN/LVN should encourage the laboring client to begin pushing when the cervix is completely dilated to 10 centimeters. Pushing before full dilation can lead to cervical injury and ineffective labor progress. By waiting for complete dilation, the client can push effectively, aiding in the descent of the baby through the birth canal. Choices A, B, and D are incorrect because pushing before complete dilation can be harmful and may not effectively help in the descent of the baby. The presence of an anterior or posterior lip of the cervix, the urge to have a bowel movement, or complete effacement of the cervix are not indicators for the initiation of pushing during labor.
