Nursing Elites

1. What is the therapeutic range for carbamazepine (Tegretol)?

• A. 7-12 mcg/mL
• B. 4-10 mcg/mL
• C. 10-14 mcg/mL
• D. 1-5 mcg/mL

Correct answer: B

Rationale: The therapeutic range for carbamazepine (Tegretol) is 4-10 mcg/mL. This range is established based on the optimal balance between effectiveness and safety. Choices A, C, and D are outside the therapeutic range for carbamazepine, which could lead to suboptimal treatment outcomes or increased risk of toxicity. Choice B (4-10 mcg/mL) is the correct range recommended for therapeutic efficacy while minimizing adverse effects.

2. 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.

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. The LPN is taking care of a client who is on Phenelzine (Nardil) for depression. Which meal would the nurse encourage the client to avoid?

• A. steak and potatoes
• B. prosciutto and cheese plate
• C. orange juice and toast
• D. carbonated water, shrimp and rice

Correct answer: B

Rationale: The correct answer is 'prosciutto and cheese plate.' Phenelzine (Nardil) is an MAOI (Monoamine Oxidase Inhibitor), and clients on these drugs should avoid foods high in tyramine due to the risk of dangerous elevations in blood pressure. Prosciutto and aged cheeses are examples of foods rich in tyramine, so they should be avoided. Choices A, C, and D do not contain high levels of tyramine and are considered safe to consume while on Phenelzine.

5. 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.
