Correct Answer: A

Rationale: The priority nursing diagnosis for a client on a mechanical ventilator receiving vecuronium bromide is 'Impaired communication related to paralysis of skeletal muscles.' Vecuronium is a skeletal muscle relaxant that causes diaphragmatic paralysis, leading to the inability of the client to communicate effectively. This is a crucial nursing concern as it impacts the client's ability to express needs and participate in care. Option B 'High risk for infection related to increased intracranial pressure' is not the priority in this scenario as the client's condition is related to the effects of the medication and mechanical ventilation, not directly to increased intracranial pressure. Option C 'Potential for injury related to impaired lung expansion' is important but not the priority over impaired communication. Option D 'Social isolation related to inability to communicate' is not the priority nursing diagnosis in this situation as it focuses more on psychosocial aspects rather than the immediate physiological concern of communication impairment.

Correct Answer: A

Rationale: The correct answer is A: 'Chemotherapy affects the cells of the body that grow rapidly, both normal and malignant.' Chemotherapy targets rapidly dividing cells, which include not only cancer cells but also healthy cells like those in hair follicles. This leads to alopecia (hair loss) as a common side effect. Choice B is incorrect as alopecia is primarily associated with chemotherapy and not long-term steroid therapy. Choice C is incorrect because while hair may grow back after chemotherapy, it may not always be to the same extent or thickness. Choice D is incorrect as chemotherapy-induced hair loss is often temporary and reversible, not permanent alterations in hair follicles.

Correct Answer: B

Rationale: Parkinson's Disease, a common neurologic progressive disorder in older clients, is characterized by symptoms such as shuffling gait, masklike facial expression, and tremors of the head and hands. Choice A is incorrect as symptoms like loss of short-term memory, facial tics, and constant writhing movements are not typically associated with Parkinson's disease. Choice C is incorrect as extreme muscular weakness, easy fatigability, and ptosis are more indicative of other conditions like myasthenia gravis. Choice D is incorrect as numbness of the extremities, loss of balance, and visual disturbances are not classic symptoms of Parkinson's disease.

Correct Answer: C

Rationale: The most important information to provide a post-menopausal female client regarding mammograms is that yearly mammograms should be done regardless of previous normal screenings. It is crucial for post-menopausal women to continue regular mammograms as they are at a higher risk for breast cancer. Option A is incorrect as breast self-examinations are still recommended in addition to mammograms. Option B is not the most important information compared to the importance of regular mammograms. Option D is not the most important advice for all post-menopausal females but specifically for those at high risk, indicating a more targeted approach.

Correct Answer: D

Rationale: The most useful information for the nurse when planning activities for a socialization group for older residents of a long-term facility would be the usual activity patterns of each resident. An older person's level of activity is a determining factor in adjustment to aging, as described by the Activity Theory of Aging. By understanding the usual activity patterns of each resident, the nurse can tailor activities that cater to their interests and abilities, promoting social engagement and overall well-being. The other options, such as the length of time residing at the facility, a brief description of family life, or the age of each resident, may provide some insights but do not directly relate to planning activities that support adjustment to aging and socialization within the group.
