Correct Answer: C

Rationale: In Erikson's theory of development, toddlers struggle to assert independence. They often use the word 'no' even when they mean yes. This stage is called autonomy versus shame and doubt. The child's behavior of saying 'no' and resisting directions reflects the developmental need for independence, not trust (option A), initiative (option B), or self-esteem (option D). Trust is typically associated with early infancy, initiative with preschool age, and self-esteem with later childhood and adolescence.

Correct Answer: D

Rationale: When a client is experiencing negative side effects associated with chemotherapy, addressing their psychosocial needs is crucial. One effective intervention is to determine the levels of support from significant others. This involves assessing the family, spouse, or friends who can provide help and support to the client when healthcare providers are not present. By identifying and organizing these resources, the nurse can help alleviate fears about the future, prepare caregivers for the client's needs, and facilitate a smoother transition for the client upon discharge. Reading discharge instructions, providing medications, or giving self-care instructions, although important, do not directly address the psychosocial needs of the client during this challenging time.

Correct Answer: C

Rationale: A client with a severe vitamin C deficiency has a condition called scurvy. Scurvy is characterized by symptoms such as bleeding gums, loose teeth, poor wound healing, and easy bruising. The correct answer is 'Bleeding gums and loose teeth' because these are classic signs of scurvy due to vitamin C deficiency. Choice A ('Cracks at the corners of the mouth') is more indicative of a deficiency in B vitamins, specifically riboflavin. Choice B ('Altered mental status') is not typically associated with vitamin C deficiency but can occur with other conditions like vitamin B12 deficiency. Choice D ('Anorexia and diarrhea') are not common symptoms of vitamin C deficiency, as they are more commonly associated with other gastrointestinal issues or deficiencies in different nutrients.

Correct Answer: A

Rationale: Infants typically double their birth weight by 6 months of age as part of normal growth and development. This doubling of weight is a common milestone used by healthcare providers to assess a baby's growth progress. Tripling the birth weight or adding 2 pounds each month would result in excessive weight gain, which is not typical or healthy for an infant. Similarly, gaining 6 ounces each week would also lead to rapid and abnormal weight gain, making it an incorrect choice.

Correct Answer: C

Rationale: A hydrocele is a collection of fluid in the scrotum that results from a patent tunica vaginalis. Illumination of the scrotum with a pocket light demonstrates the clear fluid. In most cases, the fluid reabsorbs within the first few months of life and no treatment is necessary. Massaging the groin area (Choice A) is not recommended as it will not help in the resolution of the hydrocele. Referral to a surgeon (Choice B) is not necessary at this stage since hydroceles often resolve on their own in infants. Keeping the infant in a flat, supine position (Choice D) does not aid in the reabsorption of fluid and is not a recommended intervention for hydrocele management.
