Correct Answer: A

Rationale: The correct answer is 'A: Ineffective breathing pattern.' When a client presents with insomnia, assessing for underlying causes is crucial. Sleep apnea, an airway issue, may be a contributing factor to the client's insomnia, making 'Ineffective breathing pattern' the priority. 'Disturbed sensory perception' focuses on alterations in touch, taste, or vision, which are not directly related to insomnia. 'Ineffective coping' addresses a client's inability to manage stress, which, although important, is not the priority in this case. 'Sleep deprivation' is a consequence of insomnia rather than a primary nursing diagnosis.

Correct Answer: C

Rationale: The most important goal for a client admitted to the cardiac rehabilitation unit is the identification of lifestyle changes. This is crucial in promoting cardiovascular health and preventing future cardiac issues. Lifestyle changes such as diet modifications, exercise routines, smoking cessation, and stress management play a significant role in improving the overall cardiovascular well-being of the patient. While reducing anxiety, referring to community resources, and verbalizing energy-conservation techniques are all important aspects of care, identifying lifestyle changes is the primary focus in helping the client achieve long-term cardiovascular wellness.

Correct Answer: B

Rationale: The correct answer is 'Confusion and fatigue.' Lidocaine Hydrochloride, when taken in excess, can lead to symptoms such as confusion and fatigue. It affects the central nervous system, leading to these cognitive and physical impairments. Choice A ('Memory loss and lack of appetite') is incorrect because memory loss is not a common symptom of Lidocaine Hydrochloride overdose, and lack of appetite is not a typical effect. Choice C ('Heightened reflexes') is incorrect as Lidocaine Hydrochloride overdose usually depresses reflexes rather than heightening them. Choice D ('Tinnitus and spasticity') is incorrect as tinnitus and spasticity are not commonly associated with Lidocaine Hydrochloride overdose.

Correct Answer: D

Rationale: In hyperemesis gravidarum, where the client experiences severe nausea and vomiting, the most likely electrolyte imbalance is hypokalemia. Potassium is abundant in the stomach, and excessive vomiting leads to potassium loss. Hypocalcemia (Choice A) is not typically associated with hyperemesis gravidarum. Hypomagnesemia (Choice B) and Hyponatremia (Choice C) are less likely to occur compared to hypokalemia in this condition.

Correct Answer: A

Rationale: The correct diet for a client with chronic cirrhosis is high calorie, low protein. Cirrhosis can lead to impaired protein metabolism, making it essential to limit protein intake. High-calorie foods help meet the client's energy needs. Choice B (High protein, high calorie) is incorrect because high protein intake can worsen hepatic encephalopathy. Choice C (Low fat, low sodium) is not the most appropriate diet for cirrhosis as the focus should be on calories and protein. Choice D (High calorie, low sodium) does not address the need to restrict protein intake, which is crucial in cirrhosis.
