Nursing Elites

1. What is the proper technique for obtaining a blood specimen from a central venous line?

• A. Use sterile gloves and discard the first 10 mL of blood
• B. Flush the line with heparin and then draw the specimen
• C. Draw the specimen and then administer heparin
• D. Use non-sterile gloves to reduce contamination risk

Correct answer: A

Rationale: The correct technique for obtaining a blood specimen from a central venous line is to use sterile gloves and discard the first 10 mL of blood. This practice helps ensure that the blood sample collected is not contaminated. Choice B is incorrect because flushing the line with heparin before drawing the specimen can contaminate the sample. Choice C is incorrect as administering heparin before drawing the specimen can affect the accuracy of the blood sample. Choice D is incorrect as using non-sterile gloves increases the risk of contamination, which is not recommended when obtaining a blood specimen from a central venous line.

2. A client is learning to use a cane due to left-leg weakness. Which instruction is correct?

• A. Use the cane on the stronger side of the body
• B. Maintain two points of support on the floor at all times
• C. Advance the cane and the strong leg together
• D. Advance the cane 30 to 45 cm with each step

Correct answer: B

Rationale: The correct instruction when using a cane due to leg weakness is to maintain two points of support on the floor at all times. This provides stability and support while walking. Choice A is incorrect because the cane should be used on the weaker side to provide assistance. Choice C is incorrect as the cane and weak leg should move together for support. Choice D is incorrect as advancing the cane too far with each step may compromise balance and stability.

3. What is the main symptom of left-sided heart failure?

• A. Shortness of breath
• B. Edema
• C. Increased heart rate
• D. Decreased urine output

Correct answer: A

Rationale: Shortness of breath is the main symptom of left-sided heart failure because it results from pulmonary congestion due to fluid buildup in the lungs. Edema, increased heart rate, and decreased urine output are associated with right-sided heart failure rather than left-sided heart failure.

4. The physician orders risperidone (Risperdal) for a client with Alzheimer's disease. The nurse anticipates administering this medication to help decrease which of the following behaviors?

• A. Sleep disturbances
• B. Concomitant depression
• C. Agitation and assaultiveness
• D. Confusion and withdrawal

Correct answer: C

Rationale: The correct answer is C: Agitation and assaultiveness. Risperidone is commonly prescribed for clients with Alzheimer's disease to reduce symptoms of agitation and aggressive behavior. This medication helps in managing challenging behaviors often seen in individuals with Alzheimer's. Choice A, sleep disturbances, is incorrect as risperidone is not primarily indicated for treating sleep issues in Alzheimer's patients. Choice B, concomitant depression, is also incorrect as risperidone is not the first-line treatment for depression in Alzheimer's disease. Choice D, confusion and withdrawal, is incorrect as risperidone does not directly target these symptoms in Alzheimer's patients.

5. A nurse is collecting data from a client who has Tourette syndrome. The client reports taking haloperidol 0.5 mL orally three times a day at home. Which of the following components of the prescription should the nurse question?

• A. Frequency
• B. Dosage
• C. Timing of doses
• D. Route

Correct answer: B

Rationale: The nurse should question the dosage of haloperidol as it is typically administered in milligrams (mg) and not milliliters (mL). The dosage should be expressed in a standardized unit for accuracy and to prevent medication errors. Frequency, timing of doses, and route are also important components of a prescription, but in this case, the nurse should focus on the unusual dosage form.
