Nursing Elites

1. An adult client undergoes various diagnostic tests to determine the pumping ability of the heart. The nurse notes that the results of these tests indicate that the client's cardiac output is 5 L/min. The nurse makes which conclusion?

• A. The client has a low cardiac output.
• B. The client has a high cardiac output.
• C. The client has a normal cardiac output.
• D. The client will need a blood transfusion.

Correct answer: C

Rationale: A cardiac output of 5 L/min falls within the normal range for a resting adult, which typically ranges between 4 and 6 L/min. Cardiac output is calculated as the stroke volume (volume of blood in each systole) multiplied by the heart rate. Therefore, a cardiac output of 5 L/min is considered normal. Choices A and B are incorrect as they misinterpret the result as either low or high, which is not the case based on the provided information. Choice D is unrelated to the client's cardiac output and thus incorrect.

2. A healthcare professional reviewing a client's record notes documentation that the client has melena. How does the healthcare professional detect the presence of melena?

• A. By checking the client's urine for blood
• B. By checking the client's stool for blood
• C. By checking the client's urine for a decrease in output
• D. By checking the client's bowel movements for diarrhea

Correct answer: B

Rationale: Melena' is the term used to describe abnormal black tarry stool that has a distinctive odor and contains digested blood. It usually results from bleeding in the upper gastrointestinal tract and is often a sign of peptic ulcer disease or small bowel disease. The presence of melena is detected by checking the client's stool for blood. Blood in the client's urine, decreased urine output, and diarrhea are not associated with the assessment for melena.

3. During a home visit, the LPN finds a client taking Amiodarone. Which statement by the client indicates an understanding of potential drug side effects?

• A. "It is normal if I have numbing or tingling in my feet."?
• B. "I need to make sure I wear sunblock when going outdoors."?
• C. "I need to take supplemental vitamin B12."?
• D. "I should avoid eating leafy vegetables."?

Correct answer: B

Rationale: The correct answer is B. Amiodarone can cause increased photosensitivity, making it essential for the client to wear sunblock when exposed to sunlight. Choice A is incorrect because numbing or tingling in the feet is not a common side effect of Amiodarone. Choice C is unrelated as the drug does not typically require supplemental vitamin B12. Choice D is also incorrect as there is no need to avoid leafy vegetables specifically due to Amiodarone.

4. Ms. Petty is having difficulty falling asleep. Which of the following measures promote sleep?

• A. exercising vigorously for 20 minutes each night beginning at 9:30 p.m.
• B. taking a cool shower and drinking a hot cup of tea
• C. watching TV nightly until midnight
• D. getting a back rub and drinking a glass of warm milk

Correct answer: D

Rationale: The correct answer is getting a back rub and drinking a glass of warm milk. These measures are relaxation techniques that can help promote sleep by calming the body and mind. Exercising vigorously right before bedtime, as mentioned in choice A, can increase arousal and make it harder to fall asleep. Choice B, taking a cool shower and drinking a hot cup of tea, involves temperature changes that might not be conducive to sleep. Watching TV until midnight, as in choice C, exposes the individual to blue light and mental stimulation, both of which can disrupt the natural sleep-wake cycle.

5. How often should the intravenous tubing on total parenteral nutrition solutions be changed?

• A. every 24 hours
• B. every 36 hours
• C. every 48 hours
• D. every 72 hours

Correct answer: A

Rationale: The correct answer is to change the intravenous tubing on total parenteral nutrition solutions every 24 hours. This frequency is necessary due to the high risk of bacterial growth associated with TPN solutions. Changing the tubing every 24 hours helps prevent contamination and bloodstream infections. Choices B, C, and D are incorrect because waiting longer intervals increases the risk of introducing harmful bacteria into the patient's system, leading to potentially severe complications.
