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 who is at 36 weeks of gestation is being taught about nonstress testing. Which of the following statements should the nurse include in the teaching?

• A. This test will determine the length of your cervix.
• B. You will have your blood pressure taken frequently during the test.
• C. You should press the handheld button when you feel your baby move.
• D. This test will take about 5 minutes to complete.

Correct answer: C

Rationale: The correct answer is C. In a nonstress test, the client is required to press a handheld button whenever fetal movement is felt, which is then recorded on the monitor. This action helps assess the baby's heart rate in response to its movements, providing valuable information about the baby's well-being. Choices A, B, and D are incorrect because the nonstress test does not involve determining the length of the cervix, monitoring blood pressure, or being completed in 5 minutes. These aspects are not part of the nonstress testing procedure and are unrelated to the purpose of the test.

3. A nurse is delegating the ambulation of a client who had knee arthroplasty 5 days ago to an AP. Which of the following information should the nurse share with the AP?

• A. The roommate is up independently
• B. The client ambulates with his slippers on over his antiembolic stockings
• C. The client uses a front-wheeled walker when ambulating
• D. The client had pain meds 30 minutes ago

Correct answer: C

Rationale: The correct answer is C. After knee arthroplasty, it is essential for the client to use a front-wheeled walker when ambulating to ensure stability and prevent falls. Sharing this information with the assistive personnel (AP) is crucial for the client's safety and proper rehabilitation. Choices A, B, and D are incorrect because the roommate's independence, the client's footwear over stockings, and the timing of pain medication administration are not directly related to the safe ambulation of a client post-knee arthroplasty.

4. 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.

5. A nurse is caring for a client who has diabetes mellitus and is experiencing hypoglycemia. Which of the following findings should the nurse expect?

• A. Bradycardia
• B. Tachycardia
• C. Hypotension
• D. Diaphoresis

Correct answer: A

Rationale: Corrected Rationale: Bradycardia is a common sign of hypoglycemia due to the body's response to low blood sugar. During hypoglycemia, the body releases epinephrine, leading to sympathetic nervous system activation. This can result in bradycardia as a compensatory mechanism to preserve glucose for vital organs such as the brain. Tachycardia, hypotension, and diaphoresis are more commonly associated with hypoglycemia when it progresses to severe stages and the body's compensatory mechanisms are overwhelmed.
