Which of the following measures will not help correct the patient's condition

Correct Answer: C

Rationale: Frequent oral care is important for overall oral health and cleanliness, but it will not directly help correct the patient's fluid imbalance. The patient's condition likely requires direct fluid replacement to address the fluid loss and restore balance. A, B, and D are focused on fluid replacement strategies which are more crucial in correcting the patient's condition. Offering a large amount of oral fluid intake to replace lost fluids, giving enteral or parenteral fluid, and giving small volumes of fluid at frequent intervals are all appropriate measures that can help correct the patient's condition by addressing the underlying fluid imbalance.

Correct Answer: A

Rationale: Narcotic analgesics, when given in high doses, can depress the respiratory rate and cough reflex in patients. Laryngectomy patients have had their larynx removed and may already have compromised respiratory function. Therefore, giving narcotics in low doses helps to minimize the risk of further respiratory depression in these patients. It is important to closely monitor respiratory status when administering narcotics to laryngectomy patients to prevent potential complications.

Correct Answer: A

Rationale: The nurse should examine the entire system and tubing for air leaks when observing vigorous bubbling in the water-seal chamber of a chest-drainage system. Vigorous bubbling indicates that there is air escaping from the system, which can lead to suboptimal drainage and potential complications. By identifying and correcting any air leaks, the nurse can ensure the chest-drainage system functions effectively, allowing for proper drainage and the prevention of complications such as pneumothorax. Lowering the level of suction or asking the patient to cough forcefully would not address the underlying issue of air leaks and may not resolve the problem effectively.

Correct Answer: A

Rationale: Prophylactic antibiotics are given to prevent the recurrence or complications of endocarditis in patients with a history of the condition. Endocarditis is an infection of the inner lining of the heart chambers and valves. One of the serious complications of endocarditis is the formation of vegetative emboli, which are clusters of bacteria and fibrin that can break off and travel through the bloodstream, potentially causing blockages in various organs. By preventing endocarditis, the antibiotics also help reduce the risk of vegetative emboli formation during surgical procedures or other situations where bacteria may enter the bloodstream. Therefore, the nurse's explanation to the patient about the prophylactic antibiotics is focused on preventing complications related to endocarditis, including the formation of vegetative emboli.

Correct Answer: C

Rationale: Immunity to a disease after recovery is possible because the first exposure to the pathogen has stimulated the formation of memory cells. Memory cells are a type of immune cell that "remembers" the specific pathogen encountered during the initial infection. When the same pathogen tries to infect the individual again, these memory cells quickly recognize the pathogen and mount a faster and stronger immune response, leading to a quicker recovery and preventing the person from getting sick again from the same pathogen. This immune memory is the basis of acquired immunity, providing long-lasting protection against future infections by the same pathogen.
