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: C

Rationale: The most crucial assessment during the preoperative period for a client with a sacular abdominal aortic aneurysm scheduled for surgical repair is the identification of peripheral pulses. During surgery, the aorta will be clamped, potentially affecting blood circulation to the kidneys and lower extremities. Therefore, it is essential for the nurse to assess peripheral pulses and monitor the return of circulation to the lower extremities postoperatively. Assessing the client's level of anxiety (Choice A) is important but not as crucial as ensuring adequate circulation. Evaluating exercise tolerance (Choice B) is not recommended preoperatively for this situation. Assessing bowel sounds and activity (Choice D) is of lesser concern compared to the critical need to monitor peripheral circulation.

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: D

Rationale: The correct answer is a fresh peach. It is the most suitable snack for a client with sodium restriction as it is naturally low in sodium. Peanut butter cookies (choice A), grilled cheese sandwich (choice B), and cottage cheese and fruit (choice C) contain higher amounts of sodium, making them unsuitable choices for someone on a low-sodium diet. Fresh fruits like peaches are excellent options for individuals on a low-sodium diet as they are not only low in sodium but also provide essential nutrients and hydration.

Correct Answer: B

Rationale: The correct answer is B: Denial. The client displaying denial refuses to acknowledge the reality of having a myocardial infarction. Rationalization (choice A) involves making excuses for behavior, not denying a condition. Projection (choice C) is attributing one's thoughts or feelings to others, not denying an illness. Conversion reaction (choice D) is converting psychological distress into physical symptoms, which is not evident in this scenario. Therefore, denial is the defense mechanism being used in this situation.
