Correct Answer: D

Rationale: When obtaining a urine specimen from a female infant, securing the pediatric urine collector bag to the perineum is the most appropriate intervention. This method allows for non-invasive collection of urine without causing discomfort or distress to the infant. Placing the wet diaper in a biohazard specimen bag (Choice A) is incorrect as it does not involve collecting a fresh urine sample. Using a catheter (Choice B) is invasive and not typically necessary for routine urine specimen collection from infants. Collecting the urinary stream in mid-air when the infant cries (Choice C) is not a reliable or hygienic method of obtaining a urine specimen.

Correct Answer: B

Rationale: In a client with a C-6 spinal injury exhibiting shallow respirations and dyspnea, these signs could indicate respiratory compromise and potential respiratory failure. Intubation with an endotracheal tube may be necessary to secure the airway and support adequate oxygenation. Placing the client in reverse Trendelenburg position, administering pain medication, or instructing on deep breathing exercises would not directly address the urgency of the respiratory distress in this situation, making them incorrect choices.

Correct Answer: B

Rationale: The correct instruction the nurse should include in the client's teaching plan is to empty the ostomy pouch when it is one-third full. This practice helps prevent leakage and skin irritation by maintaining an appropriate pouching system. Changing the ostomy appliance daily (Choice A) is not necessary unless leakage or other issues occur. Rinsing the ostomy pouch with warm water (Choice C) is not a recommended practice as it may cause damage to the pouch. Applying a skin barrier to the peristomal skin (Choice D) is important but not the most crucial instruction in this scenario.

Correct Answer: A

Rationale: The correct answer is A. Rifampin (Rifadin) commonly causes a reddish-orange discoloration of body fluids, including urine, sweat, saliva, and tears. This is a harmless side effect but should be reported to the healthcare provider for monitoring. Choices B, C, and D are not typically associated with rifampin therapy. Bloody or blood-tinged urine may indicate other issues such as urinary tract infection or kidney problems, blurring of vision may suggest eye problems, and significant weight gain could be related to various health conditions unrelated to rifampin.

Correct Answer: A

Rationale: In a client with heart failure presenting with worsening dyspnea and pink, frothy sputum (indicating pulmonary edema), the priority action for the nurse is to administer oxygen. Oxygen therapy helps improve oxygenation and alleviate dyspnea by increasing the oxygen supply to the lungs. Performing chest physiotherapy, elevating the head of the bed, or obtaining a sputum specimen are not the initial actions indicated in this situation and may delay addressing the client's immediate need for improved oxygenation.
