Rationale: The least helpful question in obtaining information regarding intussusception is "Describe his usual diet."? This question is least relevant to the specific symptoms and presentation of intussusception. Choices A, B, and D are more directly related to symptoms commonly associated with intussusception and can provide important diagnostic clues. Asking about pain, vomit appearance, and changes in abdominal size can help in assessing the severity and progression of the condition, making them more crucial questions to ask in this scenario. Pain is a cardinal symptom of intussusception, changes in vomit appearance may indicate gastrointestinal issues, and alterations in abdominal size can signify the presence of a mass or obstruction, all of which are pertinent in diagnosing and managing intussusception.

Correct Answer: B

Rationale: The correct answer is B: 'Egg white should not be given to my infant because of the risk for an allergy.' Egg white, even in small quantities, is not recommended for infants until the end of the first year of life due to its common allergenic potential. Choice A is incorrect because while meats are important for iron, they are not typically introduced to infants until around 6-8 months. Choice C is incorrect because food should never be mixed with formula in the bottle as it may lead to feeding difficulties and inaccurate monitoring of intake. Choice D is incorrect because fluoride supplementation may be required around 6 months depending on the infant's fluoride intake from water. Introducing solid foods like rice cereal, fruits, or vegetables is usually done around 5-6 months, following healthcare provider recommendations.

Correct Answer: B

Rationale: When caring for a client with Multiple Drug Use, it is important to understand that individuals may use more than one drug simultaneously or sequentially to enhance the effect of a particular drug or to relieve withdrawal symptoms. This practice is common among substance users. For example, heroin users may also consume alcohol, marijuana, or benzodiazepines. Combining drugs can have various effects, such as intensifying intoxication or alleviating withdrawal symptoms. It is crucial to recognize that multiple drug use can complicate assessment and intervention due to the diverse effects of different substances on the client's health. Option A is incorrect as multiple drug use is indeed common, not uncommon. Option C is incorrect because combining alcohol and barbiturates can be dangerous due to their combined depressant effects. Option D is incorrect because multiple drug use complicates assessment and intervention rather than making them easier, as the effects of different drugs on the client need to be carefully considered.

Correct Answer: C

Rationale: Carbamazepine (Tegretol) can suppress the bone marrow, leading to a decrease in the white blood cell count. A laboratory value of WBC 2,000 per cubic millimeter indicates a serious side effect of the drug. Choices A and D are within normal limits, while choice B is at the lower limit of normal. Therefore, choices A, B, and D are incorrect.

Correct Answer: C

Rationale: The correct answer is C, 'sociocultural indicator.' This client's reluctance to make new friends after experiencing a traumatic event like losing a child is a clear sign of sociocultural stress. Sociocultural stress can impact a person's social interactions, relationships, and cultural practices. Choices A, B, and D are incorrect. Choice A, 'emotional indicator,' would focus on emotional responses directly related to stress. Choice B, 'spiritual indicator,' refers to stress related to spiritual beliefs, practices, or values, which is not evident in this scenario. Choice D, 'intellectual indicator,' is not a recognized category of stress indicators in this context.
