Correct Answer: D

Rationale: A client can receive the MMR vaccine if he or she has a cold without a fever since it does not preclude vaccination. Pregnant women and immunocompromised individuals cannot receive the MMR vaccine because the rubella component is a live virus that may cause birth defects and/or disease. Being allergic to neomycin is also a contraindication as per the American Academy of Pediatrics guidelines. Individuals who have experienced anaphylactic reactions to neomycin should not receive the measles vaccine. Therefore, option D 'has a cold' is the correct choice, as the presence of a simple cold does not prevent the client from receiving the MMR vaccine.

Correct Answer: B

Rationale: In this scenario, since the couple has indicated that their family-planning goals have been met, a permanent method of contraception like sterilization would be most suitable. Sterilization offers long-term effectiveness and convenience once the decision to stop having children is made. Options like the diaphragm, male condom, or spermicide are more suitable for temporary contraception or when the family-planning goals have not yet been achieved. Therefore, the correct answer is sterilization, as it aligns with the couple's need for a convenient and permanent birth control method.

Correct Answer: C

Rationale: The correct answer is 'confidence in subordinates.' If a delegator has confidence in their subordinates' abilities, they are more likely to delegate tasks. Reasons why nurses are 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, having confidence in subordinates is not a common reason for reluctance to delegate.

Correct Answer: B

Rationale: The correct answer is B: secondary prevention. The client is currently receiving secondary prevention care. Secondary prevention focuses on early detection of disease, prompt intervention, and health maintenance for clients experiencing health problems. In this case, the electrolyte imbalance is a health problem that requires treatment to prevent further complications. Choices A, C, and D are incorrect because primary prevention is focused on health promotion and specific protections against illness before it occurs, tertiary prevention is aimed at helping rehabilitate clients after the illness is diagnosed and treated, and health promotion is a broader concept that includes activities aimed at improving overall health and well-being rather than targeting a specific health problem like an electrolyte imbalance.

Correct Answer: A

Rationale: School-age children are capable of taking responsibility for their own dental hygiene. Establishing good oral health habits during childhood can lead to a lifetime of cavity prevention. The nurse advises the parents that their children should brush with fluoride toothpaste and floss between their teeth after meals and before bedtime. This routine helps maintain good oral health and teaches children the importance of dental care. Choice A is the correct answer as it emphasizes both brushing and flossing after meals and at bedtime, which are crucial for effective dental care. Choices B, C, and D are incorrect as they do not stress the significance of both brushing and flossing after meals, which is essential for proper oral hygiene.
