Correct Answer: D

Rationale: A client can receive the MMR vaccine if he or she has a cold. A simple cold without fever does not preclude vaccination. Pregnant women and immunocompromised individuals cannot receive the MMR vaccine due to the live rubella component, which may lead to birth defects or disease. Choice C is incorrect because individuals with anaphylactic reactions to neomycin should not receive the measles vaccine according to the American Academy of Pediatrics.

Correct Answer: C

Rationale: If a delegator has confidence in their subordinates and believes a task will be performed correctly, they are more likely to delegate. Reasons nurses may be reluctant to delegate include their own lack of self-confidence, the desire to maintain authority, and getting trapped in the 'I can do it better myself' mindset. Therefore, 'confidence in subordinate' is the exception as it actually encourages delegation. The other choices are common barriers to delegation in healthcare settings.

Correct Answer: B

Rationale: Client self-determination refers to the right of clients to make their own decisions about their health care. Nursing's advocacy for clients focuses on upholding this right by supporting and respecting the autonomy and self-determination of clients. This advocacy ensures that clients are empowered to participate in decision-making regarding their health. Confidentiality, while essential, is about maintaining the privacy of client information. Malpractice insurance is a protective measure for professionals in case of errors or negligence. Health care, though crucial for enabling client self-determination, is a broad term encompassing various services and not the primary focus when discussing the client's right to autonomy.

Correct Answer: A

Rationale: The correct statement is that fat emulsions have a high energy-to-fluid-volume ratio. Fat emulsions are formulated in 10%, 20%, and 30% solutions and supply 1.1, 2, and 3 kilocalories, respectively, for each milliliter. In comparison, a milliliter of 5% dextrose only supplies 0.17 kilocalories. Choices B, C, and D are incorrect. Choice B is false because fat emulsions are essentially pH neutral and isotonic, not hypertonic. Choice C is incorrect because fat emulsions are not basic solutions; they are essentially pH neutral. Choice D is incorrect as fat emulsions are not alkaline; they are pH neutral, making them compatible with most medications.

Correct Answer: B

Rationale: The correct answer is 'the child being shaken.' In cases of suspected child abuse, bruises on both upper arms can be indicative of a child being shaken, as children who are shaken are frequently grasped by both upper arms. The presentation of a 10-month-old child being difficult to awaken, along with bruises on the upper arms, raises concern for inflicted injury. Symptoms of brain injury associated with shaking include a decreased level of consciousness. Choices A, C, and D are less likely in this scenario as they do not align with the concerning signs of suspected abuse indicated by the bruises and the child's altered level of consciousness.
