Correct Answer: D

Rationale: When educating an obese client about nutritional needs and weight loss, it is crucial to emphasize a holistic approach that involves understanding food and food products, fostering a positive mental attitude, and incorporating adequate exercise. Initiating a fast weight-loss diet is not advisable due to potential health risks and lack of long-term sustainability. Therefore, this option stands out as the exception and should not be part of the client's learning. Choices A, B, and C are essential components of a healthy weight-loss plan and should be included in the client's education.

Correct Answer: D

Rationale: The best action for the nurse to take to help a hospitalized toddler maintain a sense of control and security and ease feelings of helplessness and fear is to keep hospital routines as similar as possible to those at home. By incorporating the toddler's usual rituals and routines from home into nursing care activities, the nurse can reduce the stress of hospitalization. This approach gives the toddler a sense of familiarity, control, and security, which can alleviate feelings of helplessness and fear. Allowing the toddler to play with other children in the nursing unit playroom and selecting toys are beneficial activities, but maintaining hospital routines similar to those at home is the most effective way to support the toddler's emotional well-being during hospitalization.

Correct Answer: B

Rationale: According to Erikson's theory of psychosocial development, infants struggle to establish a sense of basic trust rather than a sense of basic mistrust in their world, their caregivers, and themselves. If provided with consistent satisfying experiences that are delivered in a timely manner, infants come to rely on the fact that their needs are met and that, in turn, they will be able to tolerate some degree of frustration and discomfort until those needs are met. This sense of confidence is an early form of trust and provides the foundation for a healthy personality. Therefore, options A, C, and D are incorrect as they do not align with Erikson's theory that emphasizes the importance of infants trusting that their needs will be met.

Correct Answer: B

Rationale: The correct answer is Teres major. The Rotator Cuff consists of Teres Minor, Infraspinatus, Supraspinatus, and Subscapularis muscles, not Teres major. Teres major is not part of the rotator cuff, so it cannot be considered as possibly being torn. The other choices, Teres minor, Supraspinatus, and Infraspinatus, are all part of the Rotator Cuff and could potentially be torn in this patient's case.

Correct Answer: A

Rationale: The correct answer is 0.9% sodium chloride. Normal saline is 0.9% sodium chloride, which has the same osmolarity as blood and does not cause cell lysis. Choices 2 and 3, 5% dextrose in water solution and sterile water, are hypotonic solutions that can lead to cell lysis. Choice 4, heparin sodium, is an anticoagulant and is not used for flushing IV devices before and after blood administration.
