Correct Answer: D

Rationale: Notifying the provider of the client's shellfish allergy is crucial to prevent a potential reaction from the contrast dye. While attaching a wristband indicating the allergy may be necessary, the priority is to inform the provider. Asking the client about other foods causing a similar reaction or notifying the dietary department, although important, are not the priority in this situation.

Correct Answer: B

Rationale: The correct nursing action for a client experiencing short-term memory loss after ECT is to offer frequent orientation and reassurance. This helps the client feel supported and aids in memory retention. Providing cognitive-behavioral therapy (Choice A) may be beneficial for other conditions but is not the primary intervention for memory loss post-ECT. Administering a sedative (Choice C) is not recommended as it may further affect memory recall. Referring the client to a neurologist (Choice D) for further evaluation is not the initial action needed; offering support and orientation should be the first approach to manage memory issues post-ECT.

Correct Answer: C

Rationale: The correct action for the nurse to take is to withdraw 3 to 5 ml of urine from the port for an accurate culture and sensitivity test. Wiping the area around the needleless port with sterile water (Choice A) is not necessary when obtaining a urine specimen. Inserting the syringe into the needleless port at a 60-degree angle (Choice B) is incorrect as it does not align with the correct procedure for obtaining a urine specimen. Donning sterile gloves (Choice D) is a good practice but not the immediate action required for obtaining a urine specimen.

Correct Answer: D

Rationale: The correct answer is to palpate the radial pulse in the left arm. When the antecubital insertion site is on the left side, it is important to assess the radial pulse on the same side to monitor circulation accurately. Palpating the brachial pulse in the right or left arm or the radial pulse in the right arm would not provide direct information about the circulation related to the catheterization site.

Correct Answer: D

Rationale: The recommended approach for handling aggressive behavior in a mental health setting is to maintain eye contact, offer clear choices, and set boundaries. This approach can help de-escalate the situation by establishing communication and structure. Choice A is incorrect as encouraging physical activity may not be suitable during an aggressive episode. Choice B is incorrect because avoiding eye contact can hinder communication and resolution. Choice C is also incorrect as pharmacological interventions should not be the immediate go-to method for managing aggression unless absolutely necessary.
