Correct Answer: A

Rationale: The correct answer is A. For an EEG, it is essential that the client's hair is clean, without any products like hairspray or gel, to ensure good electrode contact with the scalp. Choice B is not a concern as having breakfast is allowed before the test. Choice C, not taking an anticonvulsant, might be required for certain types of EEGs to capture accurate brain activity. Choice D, not drinking coffee, is not a specific requirement for an EEG preparation.

Correct Answer: D

Rationale: The correct interventions to promote kidney health in an older adult client include ensuring adequate fluid intake to maintain hydration and leaving the bathroom light on at night to promote safe ambulation. Adequate hydration supports kidney function and helps prevent urinary tract infections. Encouraging the use of the toilet every 6 hours is not specific to kidney health and may not be individualized to the client's needs. Providing thorough perineal care after each voiding is important for hygiene but not directly related to promoting kidney health. Assessing for urinary retention and urinary tract infections is crucial but falls under assessment rather than interventions for promoting kidney health specifically.

Correct Answer: A

Rationale: For a bladder training program to succeed in a client with urge incontinence, the client must be alert, aware, and able to resist the urge to urinate. Habit training will work best for a confused client. This includes going to the bathroom (or being assisted to the bathroom) at set times. The other clients may benefit from other types of bladder training. A confused client may need structured assistance to establish a regular bathroom routine, which can help manage urge incontinence effectively. Clients with diabetes mellitus, kidney failure, or arthritis may require different strategies tailored to their specific conditions.

Correct Answer: D

Rationale: Sulfonamides, like trimethoprim-sulfamethoxazole (TMP-SMX), can potentiate the anticoagulant effects of warfarin (Coumadin). To monitor the patient's response and prevent adverse effects, the healthcare professional should request coagulation studies, such as International Normalized Ratio (INR) levels. Choosing a decreased dose of TMP-SMX would not address the potential drug interaction between TMP-SMX and warfarin. Opting for a different antibiotic is not necessary if the interaction can be managed by monitoring. Increasing the dose of warfarin without monitoring could lead to excessive anticoagulation and adverse events, so it's not the appropriate action in this scenario.

Correct Answer: B

Rationale: The correct answer is B: Ketone bodies present. Ketone bodies in urine indicate abnormal metabolism, specifically the incomplete breakdown of fatty acids. Normally, there should be no ketones present in urine. Ketone bodies are produced when the body uses fat sources instead of glucose for cellular energy. A pH range between 4.6 and 8, a specific gravity between 1.005 and 1.030, and clear yellow color in urine are considered normal findings for a female client's urinalysis. Therefore, options A, C, and D are within normal ranges and not indicative of abnormal results in the urinalysis.
