A nurse is preparing to collect a stool specimen from a client for laboratory testing. Which of the following actions should the nurse take when collecting the specimen?
Wait for 4 hr before sending the specimen to the laboratory.
Avoid collecting the specimen from areas of the stool that contain blood.
Transfer the specimen to a cup without it touching the outside of the container.
Collect at least 7.62 cm (3 in) of the client's stool.
The Correct Answer is C
A. Wait for 4 hr before sending the specimen to the laboratory: Delaying the transport of stool specimens can affect test results by allowing bacterial growth or degradation of components. Specimens should be sent promptly or refrigerated if there is a delay.
B. Avoid collecting the specimen from areas of the stool that contain blood: If testing for occult blood or infection, areas with blood should be included because they provide important diagnostic information, so avoiding them is incorrect.
C. Transfer the specimen to a cup without it touching the outside of the container: Maintaining specimen integrity and preventing contamination is essential. The nurse should ensure the stool does not contact the outside of the container to avoid spreading pathogens and ensure accurate testing.
D. Collect at least 7.62 cm (3 in) of the client's stool: Collecting such a large amount is unnecessary; usually a smaller amount (about 1 inch or walnut size) is sufficient for testing, so this choice is incorrect.

Correct Answer is ["B","A","C","D"]
Explanation
A. Check the client's gastric residual: After confirming tube placement, gastric residual is assessed to evaluate delayed gastric emptying, which could increase the risk of aspiration. This is done before administering medications or feedings.
B. Verify the tube placement: Tube placement is verified first to ensure the medication is delivered into the stomach and not the lungs. This prevents aspiration and other complications associated with incorrect tube placement.
C. Pour the medication into the syringe and allow it to flow by gravity: Once placement is confirmed and residual checked, the medication is administered via gravity through the syringe to minimize pressure on the NG tube and promote safe delivery.
D. Clamp the NG tube for 20 to 30 min: After administering the medication, the NG tube is clamped to allow for medication absorption before suction is resumed. Immediate suctioning would remove the medication before it can take effect.
Correct Answer is C
Explanation
A. Headache: Headache can occur during a transfusion reaction but is usually a less urgent symptom. It should be monitored but is not the highest priority.
B. Urticaria: Urticaria (hives) often indicates a mild allergic reaction to the transfusion. It requires intervention but is generally not immediately life-threatening.
C. Dyspnea: Dyspnea signals possible respiratory distress, which may indicate a severe transfusion reaction such as anaphylaxis or transfusion-related acute lung injury (TRALI). This requires immediate attention and reporting to prevent respiratory failure.
D. Hyperthermia: A fever during transfusion suggests a febrile non-hemolytic reaction or infection risk, which is important but typically not as urgent as respiratory distress.
