A nurse is caring for a patient with heart failure who has developed pulmonary edema. What is the nurse's priority action?

Correct Answer: B

Rationale: The correct answer is to place the patient in a high Fowler's position. This position helps improve lung expansion and oxygenation in cases of pulmonary edema by reducing venous return to the heart and enhancing respiratory mechanics. Administering a diuretic (Choice A) can be important but is not the priority over positioning in this situation. Administering oxygen (Choice C) is essential, but the priority action for improving oxygenation is the positioning of the patient. Monitoring lung sounds (Choice D) is crucial for ongoing assessment but is not the priority action when the patient is in distress with pulmonary edema.

Correct Answer: C

Rationale: Elevating the head of the bed to 30-45 degrees is the most appropriate intervention to prevent aspiration in a patient with an NG tube. This position helps reduce the risk of regurgitation and aspiration by promoting the proper flow of contents through the gastrointestinal tract and minimizing the chances of stomach contents entering the airway. Flushing the NG tube with water before each feeding may not directly prevent aspiration. Checking the placement of the NG tube is important but does not specifically address the prevention of aspiration. Providing oral care every 4 hours is essential for maintaining oral hygiene but is not directly related to preventing aspiration in a patient with an NG tube.

Correct Answer: C

Rationale: The correct answer is C. The nursing student washing her hands before glove removal after emptying a Foley bag indicates a need for further teaching. Hands should be washed after glove removal to maintain proper infection control. Choice A is correct as wearing a gown when changing the bed of an incontinent client is a standard precaution. Choice B is correct as washing hands before making contact with the client is a good practice. Choice D is correct as changing gloves between tasks and procedures is a standard precaution to prevent the spread of infection.

Correct Answer: B

Rationale: The correct answer is B: Nonmaleficence. Nonmaleficence is the ethical principle that emphasizes the obligation to do no harm, making it crucial in medical decision-making. In the context of a bone marrow transplant for a client with leukemia, the primary concern is to minimize harm and avoid causing any unnecessary suffering or adverse effects. Choices A, C, and D are incorrect: Justice relates to fairness in resource allocation and treatment decisions, Autonomy involves respecting the patient's right to make decisions about their own care, and Beneficence refers to the obligation to act in the patient's best interest and promote their well-being, which may involve some level of risk or harm for overall benefit.

Correct Answer: B

Rationale: When a client expresses doubts about a procedure after signing the consent form, it is crucial to stop the surgery and consult with the surgeon. This is important to ensure that the client's concerns are addressed, and there is a clear understanding of the procedure. Reassuring the client and proceeding with the surgery (choice A) may violate the client's autonomy and right to informed consent. Proceeding with the surgery but documenting the concerns (choice C) is not sufficient as the client's doubts should be resolved before proceeding. Postponing the surgery until further clarification is provided (choice D) may be necessary, but the immediate step should be to consult with the surgeon to address the client's concerns.
