Correct Answer: D

Rationale: The correct action for external rotation of the shoulder involves moving the patient's arm until the thumb is upward and lateral to the head with the elbow flexed. This position maximizes external rotation at the shoulder joint. Choices A, moving the arm in a full circle, B, moving the arm across the body, and C, moving the arm behind the body with the elbow straight, do not describe external rotation and are incorrect. Therefore, Choice D is the correct action for performing external rotation.

Correct Answer: B

Rationale: The correct action for the nurse to take is to give information about advance directives to the client. By providing this information, the nurse empowers the client to make an informed decision about their care preferences. Choice A is incorrect because simply recording the lack of advance directive does not address the client's need for information. Choice C is incorrect because assuming the client wishes a full code without discussing it with them is not appropriate and may not align with the client's wishes. Choice D is incorrect as the nurse should directly address the issue with the client rather than involving another staff member.

Correct Answer: D

Rationale: When a nurse observes peristomal skin irritation while changing a client's colostomy pouch, it is crucial to ensure that the pouch is slightly larger (0.32 cm or 1/8 inch) than the stoma. This extra space helps prevent the pouch from rubbing against the stoma and causing further irritation. Option A is correct because colostomy pouches should be changed based on individual needs, not necessarily every 24 hours. Option B is incorrect because applying the pouch only when the skin barrier is completely dry ensures better adhesion. Option C is incorrect as patting the peristomal skin dry after cleaning is more gentle and less likely to cause irritation compared to rubbing.

Correct Answer: C

Rationale: The correct answer is to avoid taking antacids within 2 hours of phenytoin. Antacids can interfere with the absorption of phenytoin, reducing its effectiveness. Choice A is incorrect because phenytoin should not be taken with milk, as it may decrease its absorption. Choice B is unrelated to the medication and focuses on dental hygiene. Choice D is important but not directly related to phenytoin; it is more relevant to monitoring for adverse effects of the medication.

Correct Answer: C

Rationale: The correct immediate action for a healthcare worker who has been stuck by an exposed needle is to wash the hands thoroughly with soap and water to reduce the risk of infection. This helps to remove any potential pathogens introduced by the needle stick. Looking up the policy on needle sticks (Choice A) is important but not the immediate action required. Contacting employee health services (Choice B) and notifying the supervisor and risk management (Choice D) are crucial steps to take, but they should follow the initial step of washing the hands to mitigate the risk of infection.
