Correct Answer: D

Rationale: The correct answer is to change the appliance twice each week. Changing the appliance too frequently can irritate the skin around the stoma, while not changing it often enough can lead to infection. Changing the appliance twice a week helps to maintain hygiene without causing irritation. Choices A, B, and C are incorrect because changing the appliance daily can cause irritation, cleaning the stoma once a day may not be sufficient for proper hygiene, and avoiding changing the appliance for a week can increase the risk of infection and skin breakdown.

Correct Answer: A

Rationale: The correct answer is A: 'Drooping eyelids.' Ptosis, characterized by drooping of the eyelid, is a classic symptom seen in myasthenia gravis. This occurs due to muscle weakness, particularly in the muscles that control eyelid movement. Choice B, 'Unequal pupils,' is not associated with ptosis and may indicate other neurological issues. Choice C, 'Facial twitching,' is not a typical sign of ptosis but could be related to other conditions like nerve irritation. Choice D, 'Facial droop,' is more commonly seen in conditions affecting the facial nerve, like Bell's palsy, and is not a characteristic feature of myasthenia gravis.

Correct Answer: A

Rationale: The correct technique for measuring blood pressure involves placing the cuff at heart level to ensure accurate readings. Listening for Korotkoff sounds helps determine the systolic and diastolic pressures. Choice B is incorrect as inflating the cuff to 180 mmHg is excessive and can lead to inaccurate readings. Choice C is incorrect as it is unnecessary to measure blood pressure on both arms unless there is a specific medical reason to do so. Choice D is incorrect as monitoring pulse rate and applying pressure to the brachial artery are not part of the standard blood pressure measurement technique.

Correct Answer: A

Rationale: When educating a patient with hypertension about lifestyle modifications, reducing sodium intake is crucial as excess sodium can contribute to high blood pressure. While increasing physical activity is beneficial for overall health, it is not the primary lifestyle modification specifically targeted at hypertension. Quitting smoking and avoiding alcohol are important for general health but are not the first-line lifestyle modifications recommended for hypertension. Therefore, the correct answer is to reduce sodium intake.

Correct Answer: C

Rationale: When dealing with a physically assaultive client, the initial priority is to focus on restoring the client's self-control and preventing further escalation. Restricting the client to the room (choice A) may escalate the situation and is not the initial priority. Placing the client under one-to-one supervision (choice B) is important but comes after ensuring the client's self-control. Clearing the immediate area of other clients (choice D) is essential for safety but is not the initial priority when compared to restoring the client's self-control.
