Correct Answer: B

Rationale: The correct answer is B. Gently applying pressure to the front part of the ear after administering drops helps with absorption. Pulling the ear down and back is a correct technique for adults. Snugly inserting the nozzle of the ear drop bottle or placing a cotton ball all the way into the ear canal is unnecessary and can potentially cause harm or discomfort. Therefore, choices A, C, and D are incorrect.

Correct Answer: C

Rationale: The correct answer is C. Skipping meals to lose weight may indicate an eating disorder or significant distress, which can have serious health implications. This behavior raises concerns about the adolescent's physical and mental well-being. The nurse should prioritize addressing potential eating disorders and body image issues in this situation. Choices A, B, and D, while important, do not pose an immediate risk to the adolescent's health or well-being compared to the potential consequences of disordered eating behavior.

Correct Answer: A

Rationale: The correct action for the nurse to take in this situation is to ask the client why she has changed her mind. By understanding the client's reasons for refusal, the nurse can address any concerns, provide further information, and ensure that the client's decision is respected. Proceeding with the surgery without clarifying the client's decision or notifying the surgeon immediately would not be appropriate. Documenting the client's decision is important, but it should be done after understanding the rationale behind the decision.

Correct Answer: B

Rationale: Teaching about a healthy diet is considered a primary prevention activity. Primary prevention aims to prevent the onset of a disease or health problem. Educating individuals on healthy lifestyle choices, such as diet modification, falls under primary prevention. Providing cholesterol screening (choice A) is a secondary prevention measure aimed at early detection. Offering information about antihypertensive medications (choice C) falls under secondary prevention, focusing on controlling risk factors. Developing a list of cardiac rehabilitation programs (choice D) is part of tertiary prevention, focusing on rehabilitation and improving outcomes post-disease onset.

Correct Answer: B

Rationale: Restlessness and increased mucus production are common signs of gastrointestinal issues or reflux in infants, which could explain the symptoms of spitting up and excessive gas. Increased temperature and lethargy (Choice A) are more indicative of an infection rather than gastrointestinal issues. Increased sleeping and listlessness (Choice C) are not typical signs associated with the symptoms described. Diarrhea and poor skin turgor (Choice D) are not directly related to the symptoms of spitting up and gas in this scenario.
