Correct Answer: A

Rationale: Encouraging the client to use an incentive spirometer regularly is crucial in preventing postoperative complications after abdominal surgery. This action helps prevent atelectasis by promoting lung expansion and improving air exchange in the lungs, reducing the risk of respiratory complications. Assisting the client in ambulating early is important for preventing issues like deep vein thrombosis but may not directly address respiratory concerns postoperatively. Positioning the client in high Fowler's position can help with respiratory distress but is not as specific to preventing postoperative respiratory complications as using an incentive spirometer. While encouraging the client to cough and deep breathe is generally beneficial for lung expansion, using an incentive spirometer is more effective and targeted in preventing atelectasis after abdominal surgery.

Correct Answer: C

Rationale: The correct answer is C. Asking about the duration of the surgery indicates readiness to learn about the procedure. This question shows that the client is actively seeking information about the surgical process, demonstrating readiness to learn. Choices A, B, and D reflect concerns, specific requests, or statements unrelated to the learning process. They do not directly indicate readiness to absorb information about the upcoming mastectomy.

Correct Answer: C

Rationale: The correct answer is providing nasopharyngeal suctioning for a client who has pneumonia. This task falls within the practical nurse's scope of practice, as it involves direct patient care and basic interventions. Creating a plan of care for a client recovering from a stroke involves critical thinking and comprehensive assessment, which are typically responsibilities of registered nurses. Assessing a pressure injury requires specialized wound care knowledge, often performed by wound care specialists or registered nurses with wound care training. Teaching a client to use a metered-dose inhaler involves patient education and requires a thorough understanding of asthma management, making it more suitable for a registered nurse.

Correct Answer: C

Rationale: In a 2-year-old child with diarrhea and a possible ear infection, rectal temperature measurement is the most accurate reflection of core body temperature. This method provides the most reliable reading, especially in young children, as it closely reflects the core body temperature. Oral temperature may not be accurate due to the child's recent diarrhea, which can affect oral readings. Axillary temperature may not be as accurate as rectal temperature in this case. Temporal temperature measurement, although non-invasive, may not provide the most accurate core body temperature reading, especially in a child with a potential ear infection.

Correct Answer: B

Rationale: To calculate the flow rate in drops per minute (gtt/min), the formula is Total volume (mL) � Time (min) � Drop factor (gtt/mL). In this case, 1000 mL � 240 min � 20 gtt/mL = 83 gtt/min. Therefore, setting the flow rate to 83 gtt/min ensures the correct administration of the IV fluids and medication. Choices A, C, and D are incorrect as they do not align with the correct calculation based on the provided information.
