Which of the following would the nurse teach the patient is the most common site for ear infections?

Correct Answer: B

Rationale: The most common site for ear infections is the middle ear. This area is prone to infections, especially in children, due to the Eustachian tube being shorter and more horizontal compared to adults. The middle ear is connected to the upper respiratory tract, allowing bacteria or viruses to easily travel and cause infections in this area. Symptoms of a middle ear infection include ear pain, fluid buildup, and possible hearing loss. Treatment may involve antibiotics and pain relief medications, and in some cases, surgical intervention may be necessary to drain the fluid.

Correct Answer: A

Rationale: Anthropometric measurements, such as height, weight, body mass index (BMI), and waist circumference, are essential in assessing the nutritional health of a patient with Crohn's disease. These measurements provide objective data about the patient's nutritional status, body composition, and risk for malnutrition. Monitoring changes in these measurements over time can help identify nutritional deficiencies, weight loss, or malnutrition in patients with Crohn's disease. Dry skin, bleeding gums, and facial rubor can be symptoms of other health conditions, but anthropometric measurements directly assess the nutritional health of the patient.

Correct Answer: C

Rationale: When using crutches after an above the knee amputation, it is important for the client to support their weight primarily on their elbows. Placing the weight on the elbows helps to prevent pressure on the axilla (armpit area), which can lead to nerve damage and discomfort. Supporting weight on the elbows also provides better stability and control while using crutches, allowing the client to move more safely and comfortably. Additionally, distributing the weight onto the elbows helps to avoid potential strain and injury to the hands or upper arms.

Correct Answer: A

Rationale: In this situation where Mr. Mariano has an open fracture of the left humerus, the nurse's critical assessment finding should be the status of the client's tetanus immunization. An open fracture poses a risk of infection, and tetanus is a concern due to the potential exposure to bacteria from the environment causing tetanus. Tetanus is a serious bacterial infection that affects the nervous system and can be fatal if not treated promptly. Knowing the client's tetanus immunization status will help determine the need for a tetanus booster to prevent this potentially life-threatening infection. Blood alcohol level, support systems at home, and voiding time are important assessments as well, but in the case of an open fracture, the priority is to assess the risk of tetanus infection.

Correct Answer: A

Rationale: The circulating nurse is responsible for ensuring the cleanliness, proper temperature, humidity, and lighting in the operating room. The circulating nurse plays a crucial role in maintaining the overall environment and ensuring that it meets the necessary standards for the safety and well-being of the patient and the surgical team. They are in charge of coordinating and overseeing all aspects of the operating room environment, including maintaining a sterile field, assisting with instrument setup, and ensuring that all equipment is functioning properly. Additionally, the circulating nurse manages communication within the operating room and ensures that all necessary supplies are available during the surgical procedure. It is within the circulating nurse's scope of practice to take charge of these responsibilities to create an optimal operating room environment.
