Correct Answer: D

Rationale: The correct answer is D because a dyspneic patient with a tracheostomy may have difficulty speaking due to impaired airflow and mobility of the tongue. In this case, using alternative communication methods such as writing or using communication boards would be more effective. Choice A is incorrect because being blind does not directly impact communication in this scenario. Choice B is incorrect as hunger, alertness, and self-esteem do not relate to the communication challenges presented. Choice C is incorrect as depression, while important to consider, is not the primary factor impacting communication in this case.

Correct Answer: D

Rationale: The correct answer is D: Obese. This classification is based on the Body Mass Index (BMI) calculation, which takes into account weight and height. A BMI above 30 is considered obese, indicating excess body fat. Other choices are incorrect because they do not align with the BMI criteria for obesity. Choice A is incorrect as normal weight falls within a specific BMI range. Choice B is incorrect for individuals with a BMI below the normal range. Choice C is incorrect for individuals with a BMI between the overweight and obese categories.

Correct Answer: C

Rationale: The correct answer is C: Monitoring the integrity of the surgical site. This is the priority intervention as it ensures early detection of any complications like infection or bleeding. The nurse should assess for signs of infection, such as redness, swelling, or drainage, and monitor for any changes in the wound appearance. Placing the patient in high Fowler's position (A) may be beneficial for comfort but is not the priority. Administering sitz baths (B) may be helpful for comfort but should not be the priority over monitoring the surgical site. Avoiding analgesics (D) unless the pain is unbearable is not appropriate as pain management is essential for the patient's comfort and recovery.

Correct Answer: D

Rationale: The correct answer is D: Isolate affected residents from residents who have not developed conjunctivitis. This is the most appropriate action to prevent the spread of viral conjunctivitis in a long-term care facility. By isolating affected residents, the nurse can minimize the risk of transmission to other residents. Choice A is incorrect because prophylactic antibiotics are not effective against viral conjunctivitis. Choice B is also incorrect as normal saline does not treat viral conjunctivitis but may provide comfort. Choice C is unnecessary as viral conjunctivitis is typically diagnosed clinically and does not require culture testing.

Correct Answer: A

Rationale: The correct answer is A: Rinsing the ears with normal saline after swimming. This is because rinsing with normal saline helps to remove excess moisture and debris, preventing bacterial growth that can lead to otitis externa. Avoiding loud noises (B) is important for overall ear health but does not specifically prevent otitis externa. Instilling antibiotic ointments regularly (C) is not recommended as it can disrupt the ear's natural flora. Avoiding cotton swabs (D) is important to prevent injury but does not directly prevent otitis externa.
