Nursing Elites

1. Which of the following represents a normal serum potassium level?

• A. 1.5 mEq/L
• B. 3.0 mEq/L
• C. 4.0 mEq/L
• D. 6.0 mEq/L

Correct answer: C

Rationale: The correct answer is 4.0 mEq/L. Normal serum potassium levels typically range from 3.5-5.5 mEq/L. Choice A (1.5 mEq/L) is below the normal range, Choice B (3.0 mEq/L) is also below the normal range, and Choice D (6.0 mEq/L) is above the normal range. Therefore, the only option within the normal range is Choice C (4.0 mEq/L).

2. As part of the teaching plan for a client with type I diabetes mellitus, the nurse should include that carbohydrate needs might increase when:

• A. an infection is present.
• B. there is an emotional upset.
• C. a large meal is eaten.
• D. active exercise is performed.

Correct answer: D

Rationale: During active exercise, insulin sensitivity increases, leading to lower blood glucose levels. To balance the effect of increased insulin sensitivity, additional carbohydrates might be needed. The other choices are incorrect because: A) an infection typically raises blood glucose levels rather than increasing the need for carbohydrates; B) emotional upset can impact blood glucose but does not directly affect carbohydrate needs; C) while a large meal can raise blood glucose levels, it does not necessarily mean an increase in carbohydrate needs.

3. The nurse provides a postoperative client with an analgesic medication and darkens the room before the client goes to sleep for the night. The nurse's actions:

• A. help decrease stimuli from the cerebral cortex.
• B. stimulate hormonal changes in the brain.
• C. help the client's circadian rhythm.
• D. alert the hypothalamus in the brain.

Correct answer: A

Rationale: The nurse's actions of providing an analgesic medication and darkening the room aim to decrease stimuli from the cerebral cortex. Reduction of environmental stimuli, especially light and noise, from the cerebral cortex, which is an area of arousal, facilitates sleep. By decreasing input to this area, the client is more likely to fall asleep and stay asleep. Choices B, C, and D are incorrect because the scenario does not involve stimulating hormonal changes, influencing the circadian rhythm, or alerting the hypothalamus.

4. A nurse is taking a morning break with the unit secretary in the nurses' lounge. The unit secretary says to the nurse, 'I read in Mr. Gage's medical record that he has gonorrhea.' How should the nurse respond to the secretary?

• A. Yes, he does, but be sure not to discuss this with anyone else.
• B. Yes, that's why we've imposed contact precautions.
• C. We can't discuss a client's medical condition.
• D. Oh, really? I didn't see that!

Correct answer: C

Rationale: A client's medical condition is confidential and should never be discussed with anyone other than the client and the client's healthcare provider. Therefore, the nurse must tell the unit secretary that the client's condition is not to be discussed. Choices A and B confirm the client's disease, which is inappropriate as it breaches patient confidentiality. Choice D promotes further discussion of the client's condition, which is also inappropriate. The correct response is to firmly state, 'We can't discuss a client's medical condition,' to uphold patient privacy and confidentiality.

5. A nurse monitoring a client with a chest tube notes that there is no tidaling of fluid in the water seal chamber. After further assessment, the nurse suspects that the client's lung has reexpanded and notifies the healthcare provider. The healthcare provider verifies with the use of a chest x-ray that the lung has reexpanded, then calls the nurse to ask that the chest tube be removed. Which action should the nurse take first?

• A. Explain the procedure to the client, then remove the chest tube.
• B. Call the nursing supervisor.
• C. Inform the healthcare provider that removal of a chest tube is not a nursing procedure.
• D. Obtain petrolatum-impregnated gauze and ask another nurse to assist in removing the chest tube.

Correct answer: C

Rationale: The correct action for the nurse to take first is to inform the healthcare provider that removal of a chest tube is not a nursing procedure. Actual removal of a chest tube is the duty of a healthcare provider. If the healthcare provider insists that the nurse remove the tube, the nurse must contact the nursing supervisor. Some agencies' policies and procedures may permit an advanced practice nurse to remove a chest tube, but there is no information in the question to indicate that the nurse is an advanced practice nurse. Choice A is incorrect because the nurse should not proceed with removing the chest tube without proper authorization. Choice B is incorrect as calling the nursing supervisor should come after clarifying with the healthcare provider. Choice D is incorrect as the nurse should not begin the process of removing the chest tube without proper guidance and authorization.
