Correct Answer: A

Rationale: Paralytic ileus is a condition where there is a temporary paralysis of the bowel, leading to absent bowel sounds and abdominal distention. This occurs because the bowel is not functioning properly to propel contents, resulting in a lack of bowel sounds. Absent bowel sounds with distention are typical findings in paralytic ileus. Hyperactive bowel sounds with pain are more indicative of increased motility and are not expected in paralytic ileus. Normal bowel sounds with cramping may be seen in other conditions, such as gastroenteritis. Diminished bowel sounds with tenderness are not typical findings in paralytic ileus.

Correct Answer: A

Rationale: When an irregular pulse is detected, it is essential to count the apical pulse rate for a full minute to accurately determine the rhythm. This ensures a comprehensive assessment and helps in identifying any potential issues or abnormalities. Rechecking the pulse at the same site after 5 minutes (Choice B) may not provide an immediate understanding of the irregularity. Measuring the client's blood pressure (Choice C) is important but not directly related to addressing the irregular pulse. Recording the irregularity and continuing with other vital signs (Choice D) may overlook a potentially serious cardiac issue that requires immediate attention.

Correct Answer: C

Rationale: The correct technique for using a flow-oriented incentive spirometer involves breathing in slowly and deeply to raise the ball or piston. This action helps to expand the lungs and improve lung function. Option A is incorrect as coughing deeply after each use is not part of using the spirometer. Option B is incorrect as holding the breath for 10 seconds is not the correct instruction for using the spirometer. Option D is incorrect as exhaling forcefully before using the spirometer is not the appropriate step in using this device.

Correct Answer: D

Rationale: A fever of 101.5°F (38.6°C) in a client undergoing chemotherapy is a significant finding that may indicate an underlying infection, which can be life-threatening due to the client's compromised immune system. Prompt reporting and intervention are crucial to prevent complications. Mild nausea, hair loss, and increased fatigue are common side effects of chemotherapy and are expected findings that do not typically require immediate reporting unless they are severe or significantly impacting the client's well-being. Therefore, the LPN/LVN should prioritize reporting the fever over the other options.

Correct Answer: A

Rationale: When a client is using a nasal cannula for oxygen therapy, the areas prone to skin damage are the tops of the ears and around the nostrils. The pressure exerted by the cannula on these areas can lead to skin breakdown, so it is important for the nurse to observe these sites for any signs of damage. The correct answer is 'Tops of the ears.' Choices 'Bridge of the nose' and 'Over the cheeks' are not typically areas where skin damage related to the cannula would occur, making them incorrect choices.
