Correct Answer: A

Rationale: As Parkinson's disease progresses and complications develop, impaired physical mobility is a relevant nursing diagnosis due to symptoms like a shuffling gait and rigidity that can impair movement. Dysreflexia is not typically associated with Parkinson's disease; it is more commonly seen in spinal cord injuries. Hypothermia is a condition of low body temperature and is not directly related to Parkinson's disease progression. Impaired Dentition involves issues with teeth and oral health, which are not specific to Parkinson's disease complications.

Correct Answer: B

Rationale: When cleaning a client's PEG tube, the nurse should perform tasks that focus on gentle cleaning and avoiding potential irritants. Choice A is correct as gently removing crusty drainage helps maintain hygiene. Choice C is important to prevent skin irritation and infection. Choice D is appropriate for cleaning the area. Choices B and D are incorrect. Choice B is incorrect because pulling the tube in multiple directions can lead to dislodgement or injury. Choice B is incorrect as talcum powder may irritate the stoma, and it is generally not recommended near PEG tubes.

Correct Answer: B

Rationale: Correct! When sizing an oropharyngeal airway, the nurse should measure from the corner of the client's mouth to the tragus of the ear. This measurement ensures that the airway is the appropriate length to reach the pharynx without being too long or too short. Choices B, C, and D are incorrect as they do not provide the correct anatomical landmarks for determining the size of an oropharyngeal airway. Measuring from the corner of the mouth to the tragus of the ear is a standard method to ensure proper airway size and prevent complications during airway management.

Correct Answer: A

Rationale: The correct instruction for a client undergoing mammography is not to use underarm deodorant. Underarm deodorant can cause confusing shadows on the X-ray film, affecting the accuracy of the mammogram. Choices B, C, and D are incorrect. While wearing comfortable clothing is advisable, it is not the primary instruction for mammography. Avoiding caffeine and bringing a list of current medications are not specific instructions related to mammography preparation and are therefore not the correct answers.

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.
