Question 1 of 5

How often should intravenous tubing for TPN solutions be changed?

Correct Answer: A

Rationale: The correct answer is A (Every 24 hours) because TPN solutions are at high risk for contamination, making it crucial to change the tubing frequently to prevent infection. Changing the tubing every 24 hours helps maintain sterility and reduces the risk of microbial growth. Choices B, C, and D are incorrect because prolonging the tubing change interval increases the likelihood of bacterial colonization and poses a higher risk of infection for the patient receiving TPN. It is essential to adhere to the recommended 24-hour tubing change frequency to ensure patient safety and minimize the potential for complications.

Question 2 of 5

What is the appropriate intervention for a client with suspected genitourinary trauma and visible blood at the urethral meatus?

Correct Answer: D

Rationale: The correct answer is D: Urologist consult. This is the appropriate intervention for a client with suspected genitourinary trauma and visible blood at the urethral meatus because a urologist is an expert in diagnosing and managing issues related to the genitourinary system. They can perform a thorough evaluation, order appropriate tests (such as imaging studies), and provide the necessary treatment for any potential trauma. Option A (Insert a Foley catheter) could worsen the trauma if there is an underlying injury. Option B (In and out catheter specimen) and Option C (Voided urine specimen) focus on specimen collection and do not address the potential trauma, making them inappropriate interventions in this situation. Consulting a urologist ensures proper assessment and management of the suspected genitourinary trauma.

Question 3 of 5

What is the proper hand position when performing chest vibration?

Correct Answer: B

Rationale: The correct hand position for performing chest vibration is to spread the fingers. This allows for a larger surface area of contact with the chest, promoting effective transmission of vibrations to loosen chest secretions. Flattening the hands would reduce the effectiveness of the vibrations by limiting contact area. Cupping the hands creates a smaller contact area and may concentrate the pressure too much in one spot, potentially causing discomfort or injury. Therefore, spreading the fingers is the optimal hand position for chest vibration technique.

Question 4 of 5

What assessment should the nurse perform when a client is wearing a cast?

Correct Answer: A

Rationale: The correct answer is A because capillary refill, warm toes, and no discomfort indicate good circulation and nerve function under the cast. This assessment helps detect any complications like impaired circulation or nerve damage. Posterior tibial pulses and moisture are not directly related to cast assessment. Pain threshold is subjective and does not provide objective information. Discomfort of the metacarpals is specific and not a comprehensive assessment.

Question 5 of 5

What precaution should be taken when administering intravenous electrolyte solutions?

Correct Answer: C

Rationale: Correct Answer: C Rationale: 1. Preventing infiltration of calcium is crucial to avoid tissue necrosis and sloughing. 2. Infiltration of calcium can lead to severe tissue damage and potential harm to the patient. 3. Monitoring for signs of infiltration during administration of electrolyte solutions is essential. 4. Administering calcium-containing solutions cautiously can prevent serious complications. 5. Ensuring proper placement of the IV line and monitoring for any signs of infiltration is key. Summary: A: Infusing hypertonic solutions rapidly can lead to adverse effects, such as fluid overload. B: Limiting potassium to 80 mEq per liter is important, but not directly related to preventing calcium infiltration. D: Reevaluating digitalis dosage is important in clients receiving electrolyte solutions but not directly related to preventing calcium infiltration.
