Immunocompromised patients are best nursed using:

Correct Answer: C

Rationale: The correct answer is C: Reverse barrier nursing. Immunocompromised patients need protection from infections. Reverse barrier nursing involves protecting the patient from potential infections by wearing personal protective equipment (PPE) to prevent the spread of pathogens. This method is crucial as it helps reduce the risk of infections in immunocompromised patients. Barrier nursing (choice A) involves protecting healthcare workers from patient infections, not the other way around. Intensive care nursing (choice B) focuses on critically ill patients but does not specifically address the unique needs of immunocompromised patients. Isolation nursing (choice D) may involve physical separation but does not necessarily incorporate the comprehensive protective measures of reverse barrier nursing.

Correct Answer: A

Rationale: The correct answer is A: Acute asthma. A 7-year-old client with tachypnea, afebrile status, and a nonproductive cough is more likely to have acute asthma. Asthma commonly presents with these symptoms in children. Tachypnea is a common sign of asthma due to airway inflammation and narrowing. The absence of fever and productive cough makes bronchial pneumonia less likely. COPD and emphysema are typically seen in adults and are rare in children, making them incorrect choices for this age group and presentation.

Correct Answer: B

Rationale: Correct Answer: B Rationale: 1. Nurse Trish's first response should be to cover the wound with a saline-soaked sterile dressing to prevent infection and keep the exposed tissues moist. 2. This action helps protect the wound and organs from further damage or contamination. 3. It is important to maintain the sterility of the dressing to minimize the risk of infection. 4. Calling the physician can be the next step after stabilizing the wound with the dressing. 5. Taking blood pressure and pulse is important but not the immediate priority in this situation. 6. Pulling the dehiscence closed is contraindicated as it can cause further harm and should not be attempted by the nurse.

Correct Answer: C

Rationale: The correct answer is C: Chronic obstructive bronchitis. A 56-year-old client with chronic cough, peripheral edema, and cyanotic nail beds likely has chronic obstructive bronchitis due to the presence of chronic cough and cyanosis, which are common symptoms. Peripheral edema can be seen in advanced stages. ARDS (choice A) is typically seen in acute conditions, not chronic. Asthma (choice B) usually presents with wheezing and shortness of breath, not peripheral edema. Emphysema (choice D) is characterized by shortness of breath and barrel chest, not peripheral edema or cyanosis.

Correct Answer: A

Rationale: The correct answer is A: Keep a closed sterile drainage system. This is crucial to prevent infection by maintaining a closed system, reducing the risk of introducing bacteria into the bladder. The closed system prevents ascending infection. Choice B is incorrect because routine catheter irrigation can introduce pathogens into the bladder. Choice C is incorrect because keeping the bag lower than the bed can lead to reflux of urine back into the bladder, increasing the risk of infection. Choice D is incorrect because while measuring intake and output is important for monitoring fluid balance, it is not a direct safety measure for catheter care.
