Correct Answer: C

Rationale: The correct action the nurse should take when caring for a child with cystic fibrosis receiving postural drainage is to hold the hand flat to perform percussion. This technique allows for effective chest physiotherapy. Choice A is incorrect because postural drainage should be performed before meals to prevent vomiting during the procedure. Choice B is incorrect because bronchodilators are typically administered before postural drainage to help open up the airways. Choice D is incorrect as the frequency of postural drainage may vary depending on the individual's condition, so performing it twice a day may not be appropriate for all patients.

Correct Answer: D

Rationale: The correct answer is D: Whole milk. Clients with cholecystitis should avoid high-fat foods, and whole milk contains high levels of fat. Bananas, oatmeal, and brown rice are generally considered safe for clients with cholecystitis as they are low in fat and easily digestible. Bananas are a good source of potassium, oatmeal is high in fiber, and brown rice provides complex carbohydrates. Therefore, the nurse should advise the client to avoid whole milk but can recommend the other choices as part of a balanced diet for cholecystitis.

Correct Answer: A

Rationale: The correct statement for the nurse to make is to advise the client to check the oxygen equipment daily for proper function. This is crucial to ensure the client's home oxygen therapy is working effectively and safely. Choice B is incorrect because adjusting the oxygen flow rate without healthcare provider guidance can be dangerous. Choice C is incorrect as oxygen tanks should be stored upright, not lying flat. Choice D is incorrect and unsafe advice, as smoking near an oxygen source can lead to a fire hazard.

Correct Answer: A

Rationale: The correct answer is A: Canned soup. Canned soups are usually high in sodium, which can increase blood pressure and should be avoided by clients with hypertension. Lean cuts of beef, bananas, and baked chicken are healthier options for individuals with hypertension as they are lower in sodium and can be included in a balanced diet to manage blood pressure levels.

Correct Answer: D

Rationale: The correct answer is D. Developing a system for staff members to report safety concerns in the client care environment is crucial to promoting client advocacy and ensuring client safety. This action empowers staff to identify and address potential safety issues, ultimately enhancing the quality of care provided. Choices A, B, and C are incorrect. Choice A suggests implementing paternalism, which involves making decisions for clients without their input, contradicting the principles of client advocacy. Choice B focuses on informed consent procedures, which are important but do not directly relate to promoting client advocacy among staff. Choice C, sharing personal experiences, may not always align with professional boundaries and can potentially bias clients' decision-making processes.
