Nursing Elites

1. A nurse reviews the electrolyte results of an assigned client and notes that the potassium level is 5.4 mEq/L. Which of the following would the nurse expect to note on the electrocardiogram as a result of the laboratory value?

• A. ST depression
• B. Inverted T wave
• C. Prominent U wave
• D. Tall peaked T waves

Correct answer: D

Rationale: The correct answer is 'Tall peaked T waves.' Tall peaked T waves are characteristic ECG changes associated with hyperkalemia. In hyperkalemia, the elevated potassium levels affect the myocardium, leading to changes in the ECG. ST depression (Choice A) is more commonly associated with myocardial ischemia or infarction. Inverted T wave (Choice B) is seen in conditions like myocardial ischemia or CNS events. Prominent U wave (Choice C) is typically associated with hypokalemia or certain medications. Therefore, in this scenario, the nurse would expect to note tall peaked T waves on the electrocardiogram due to the elevated potassium level.

2. Which statement about glaucoma is true and accurate?

• A. Acute angle-closure glaucoma is an ocular emergency.
• B. Acute angle-closure glaucoma leads to the loss of peripheral vision and tunnel vision.
• C. Primary open-angle glaucoma leads to eye pain, nausea, and vomiting, blurry vision, and halos.
• D. Bubbles are implanted to protect the retina from glaucoma.

Correct answer: A

Rationale: The correct answer is A: 'Acute angle-closure glaucoma is an ocular emergency.' Acute angle-closure glaucoma is indeed considered an ocular emergency that requires immediate attention to prevent vision loss. Choice B is incorrect because acute angle-closure glaucoma commonly presents with symptoms like severe eye pain, headache, blurred vision, and halos around lights. Choice C is incorrect as these symptoms are more indicative of acute angle-closure glaucoma rather than primary open-angle glaucoma. Choice D is incorrect since bubbles are not typically used to protect the retina from glaucoma; treatment usually involves medications, laser therapy, or surgery to manage intraocular pressure.

3. A nurse is preparing a client for surgery. The client has signed the consent form but tells the nurse that she has reconsidered because she is worried about the pain. Which of the following responses by the nurse is appropriate?

• A. If you have the procedure now, you won't have to deal with pain and disability later.
• B. You'll be fine. You'll receive a prescription for pain medication.
• C. Why didn't you discuss your concerns with your provider?
• D. I understand and it's not too late to change your mind.

Correct answer: D

Rationale: The appropriate response acknowledges the client's concern and confirms that they have the right to change their mind.

4. What is the normal sodium level in the body?

• A. 135 to 145 milliequivalents per liter.
• B. 3 to 5 milliequivalents per liter.
• C. 135 to 145 microequivalents per liter.
• D. 3 to 5 microequivalents per liter.

Correct answer: A

Rationale: The correct answer is A: 135 to 145 milliequivalents per liter. The normal range for sodium levels in the body is expressed in milliequivalents per liter, not microequivalents. Choice B and D provide a significantly lower range which is not within the normal values for sodium. Choice C incorrectly states 'microequivalents' instead of the correct unit 'milliequivalents'. Therefore, A is the correct answer.

5. A charge nurse making rounds observes that an assistive personnel (AP) has applied wrist restraints to a client who is agitated and does not have a prescription for restraints. Which of the following actions should the nurse take first?

• A. Remove the restraints from the client's wrists
• B. Review the chart for nonrestraint alternatives for agitation
• C. Speak with the AP about the incident
• D. Inform the unit manager of the incident

Correct answer: A

Rationale: The correct action for the nurse to take first is to remove the restraints from the client's wrists. Restraints should not be applied without a prescription due to the risk of harm to the client. Removing the restraints promptly is a priority to ensure the client's safety. Reviewing nonrestraint alternatives, speaking with the AP, and informing the unit manager can follow after ensuring the client's immediate safety by removing the restraints.
