Correct Answer: A

Rationale: Variable decelerations can indicate cord compression as they are caused by umbilical cord compression or prolapse. This pattern shows an abrupt decrease in heart rate with an erratic shape, often resembling a V or W. Early decelerations (choice B) are typically caused by head compression during contractions and are considered benign. Bradycardia (choice C) is a consistent low heart rate below 110 bpm and is not specific to cord compression. Tachycardia (choice D) is an abnormally high heart rate above 160 bpm and is not associated with cord compression.

Correct Answer: C

Rationale: The correct answer is to inform the client that they can lie down in about 30 minutes. After administering medication through an NG tube, it is recommended that the client remains upright for about 30 minutes to ensure proper absorption of the medications. Option A is incorrect as waiting for 1 hour is unnecessary. Option B is incorrect as the specified timeframe and condition given are not standard practice for lying down after NG tube medication administration. Option D is incorrect as it lacks guidance on the appropriate waiting time and does not emphasize the importance of waiting before lying down for optimal medication absorption.

Correct Answer: A

Rationale: The correct action for the nurse to take when sensing a tingling sensation while lowering the bed with a comatose client is to unplug the bed's power source. This should be the initial step as there may be a fault in the bed's grounding. Removing the client from the bed immediately is not safe until the electrical issue is resolved. Notifying the biomedical department is important but should come after ensuring the immediate safety of the client. Turning off the oxygen is not necessary unless there is a specific issue related to oxygen delivery, which is not indicated in this scenario.

Correct Answer: A

Rationale: The correct answer is 'Impaired Physical Mobility.' As Parkinson's disease progresses, clients may experience a shuffling gait and rigidity, leading to impaired physical mobility. This nursing diagnosis is relevant to address the functional limitations that may arise. 'Dysreflexia' is not typically associated with Parkinson's disease but rather with spinal cord injuries. 'Hypothermia' is a condition of abnormally low body temperature and is not a common complication of Parkinson's disease. 'Impaired Dentition' refers to dental issues and is not directly related to the progression of Parkinson's disease.

Correct Answer: A

Rationale: A high ammonia level can lead to hepatic encephalopathy, which includes symptoms like confusion, disorientation, and can progress to coma. Coma is a severe condition of unconsciousness. Edema is swelling caused by excess fluid trapped in body tissues, not typically associated with high ammonia levels. Hypoxia is a condition of inadequate oxygen supply to tissues and organs, not directly related to high ammonia levels. Polyuria is excessive urination, which is not a typical sign of high ammonia levels.
