Nursing Elites

1. To obtain a sterile urine specimen from a client with a Foley catheter, the nurse begins by applying a clamp to the drainage tubing distal to the injection port. What does the nurse do next?

• A. Clamp another section of the tube to create a fixed sample section for retrieval.
• B. Insert a syringe into the injection port and aspirate the quantity of urine required.
• C. Clean the injection port cap of the drainage tubing with povidone-iodine solution.
• D. Withdraw 10 mL of urine and discard it; then withdraw 10 mL more for the sample.

Correct answer: C

Rationale: After clamping the drainage tubing, the next step in obtaining a sterile urine specimen from a client with a Foley catheter is to clean the injection port cap of the drainage tubing with povidone-iodine solution. This cleaning step helps prevent contamination of the urine sample. Clamping another section of the tube isn't necessary and may not be a standard practice. Inserting a syringe into the injection port to aspirate urine isn't the correct step at this point. Withdrawing 10 mL of urine and discarding it before collecting the sample isn't appropriate and may lead to an inaccurate sample.

2. A nurse is caring for several clients with dehydration. The nurse assesses the client with which finding as needing oxygen therapy?

• A. Tenting of skin on the back of the hand
• B. Increased urine osmolarity
• C. Weight loss of 10 pounds
• D. Pulse rate of 115 beats/min

Correct answer: D

Rationale: The correct answer is the pulse rate of 115 beats/min. A rapid pulse rate is a sign of compensatory mechanisms in response to dehydration, indicating that the body is trying to deliver oxygen more efficiently. Oxygen therapy may be needed to support the increased oxygen demand. Tenting of skin on the back of the hand is a classic sign of dehydration due to decreased skin turgor. Increased urine osmolarity and weight loss are also indicators of dehydration, but they do not directly suggest a need for oxygen therapy.

3. What intervention is most important to teach the client about identifying the onset of dehydration?

• A. Measuring abdominal girth
• B. Converting ounces to milliliters
• C. Obtaining and charting daily weight
• D. Selecting food items with high water content

Correct answer: C

Rationale: The correct answer is C: Obtaining and charting daily weight. Monitoring daily weight is crucial in identifying the onset of dehydration as weight loss can be an early sign. Measuring abdominal girth (choice A) is not the most reliable method for detecting dehydration. Converting ounces to milliliters (choice B) and selecting food items with high water content (choice D) may be important for overall hydration but are not the most critical interventions for identifying the onset of dehydration.

4. The healthcare provider is assessing a client before surgery. Which assessments contraindicate the client from having surgery as scheduled? (Select one that does not apply.)

• A. Potassium level of 2.8 mEq/L
• B. International normalized ratio (INR) of 4
• C. Prothrombin time (PT) of 30 seconds
• D. Positive pregnancy test

Correct answer: C

Rationale: The correct answer is C: Prothrombin time (PT) of 30 seconds. A low potassium level (choice A) and an elevated INR (choice B) indicate potential bleeding risks during surgery. A positive pregnancy test (choice D) in a female client can lead to complications during surgery. However, a Prothrombin time of 30 seconds is within the normal range and does not contraindicate the client from having surgery as scheduled.

5. When obtaining a client’s vital signs, the nurse assesses a blood pressure of 134/88 mm Hg. What is the nurse’s best intervention?

• A. Call the healthcare provider and report the finding.
• B. Reassess the client’s blood pressure at the next follow-up appointment.
• C. Administer an additional antihypertensive medication to the client.
• D. Teach the client lifestyle modifications to decrease blood pressure.

Correct answer: D

Rationale: The correct answer is to teach the client lifestyle modifications to decrease blood pressure. A blood pressure reading of 134/88 mm Hg falls within the prehypertension range. The initial approach to managing prehypertension involves lifestyle modifications such as dietary changes, exercise, and stress reduction techniques. Calling the healthcare provider without attempting non-pharmacological interventions first is premature. Reassessing blood pressure at the next follow-up appointment may delay necessary interventions. Administering additional antihypertensive medication is not indicated at this stage as lifestyle modifications are the first line of treatment for prehypertension.
