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. The doctor has ordered 20 cc per hour of normal saline intravenously for your pediatric patient. You will be using pediatric intravenous tubing that delivers 60 cc per drop. How many drops per minute will you administer using this pediatric intravenous set?

• A. 30 drops per minute
• B. 25 drops per minute
• C. 20 drops per minute
• D. 22 drops per minute

Correct answer: C

Rationale: To calculate the drops per minute, first convert the ordered amount to drops per minute. 20 cc per hour equals 20 drops per hour with 60 cc per drop tubing, which is equivalent to 20 drops per hour * 60 cc per drop = 1200 drops per hour. To find drops per minute, divide 1200 by 60 (minutes in an hour), which equals 20 drops per minute. Therefore, the correct answer is 20 drops per minute. Choices A, B, and D are incorrect as they do not reflect the correct calculation based on the provided information.

3. What is the main objective of palliative care?

• A. To cure the disease
• B. To provide relief from symptoms and improve quality of life
• C. To extend hospital stays
• D. To focus solely on treatment

Correct answer: B

Rationale: The main objective of palliative care is to provide relief from symptoms and improve quality of life. Palliative care focuses on enhancing the quality of life for patients facing serious illnesses by providing relief from symptoms such as pain, stress, and other physical and emotional issues. Choice A is incorrect because palliative care does not aim to cure the disease but rather to manage symptoms. Choice C is incorrect as the goal of palliative care is not to extend hospital stays unnecessarily but to improve the patient's well-being. Choice D is incorrect as palliative care is not solely focused on treatment but takes a holistic approach to care that includes addressing physical, emotional, social, and spiritual needs.

4. The doctor has ordered 500 mg of a medication PO once a day. The tablets on hand are labeled as 1 tablet = 250 mg. How many tablets will you administer to your patient?

• A. 1 Tablet
• B. 2 Tablets
• C. 3 Tablets
• D. 4 Tablets

Correct answer: B

Rationale: To calculate the number of tablets needed, divide the total dosage prescribed (500 mg) by the dosage per tablet (250 mg per tablet). 500 mg / 250 mg per tablet = 2 tablets. Therefore, the correct answer is 2 tablets. Choices A, C, and D are incorrect as they do not accurately reflect the correct calculation based on the provided information.

5. Which of the following best describes evidence-based practice?

• A. Using outdated research
• B. Relying on personal experience alone
• C. Integrating clinical expertise with the best available evidence
• D. Disregarding patient preferences

Correct answer: C

Rationale: Evidence-based practice involves integrating clinical expertise with the best available evidence to make informed decisions about patient care. Choice A is incorrect as evidence-based practice relies on current and relevant research. Choice B is incorrect as it emphasizes the importance of not relying solely on personal experience. Choice D is incorrect as patient preferences play a significant role in evidence-based practice.
