The practical nurse (PN) is auscultating a client’s lung sounds and hears a high-pitched, continuous, musical sound during breathing. Which description should the PN use to document this sound?

Choice A rationale:

The combination of trimethoprim and sulfamethoxazole has a synergistic effect, which means that the two drugs work together to inhibit bacterial growth more effectively than either drug alone. This combination is commonly used to treat urinary tract infections (UTIs) caused by susceptible bacteria.

Choice B rationale:

The combination of trimethoprim and sulfamethoxazole does not have an additive effect that reduces the dosage and frequency of administration of each drug. Instead, it is prescribed as a fixed combination with specific dosages of each drug.

Choice C rationale:

The combination of trimethoprim and sulfamethoxazole does not have an antagonistic effect that prevents the development of resistance to either drug. In fact, the combination is chosen because it covers a broader spectrum of bacteria and reduces the likelihood of resistance development.

Choice D rationale:

The combination of trimethoprim and sulfamethoxazole does not have a selective effect that targets only the bacteria causing the UTI and spares the normal flora. It affects a wide range of bacteria, including both pathogenic and normal flora.

Choice A rationale:

Assigning a client who is one day postoperative for a laparoscopic cholecystectomy to the practical nurse (PN) is appropriate. This procedure is minimally invasive, and the client is likely stable, requiring routine postoperative care such as wound assessment, pain management, and monitoring for any signs of complications.

Choice B rationale:

An older client who is one day postoperative with a colostomy for colon cancer may have complex postoperative needs, including colostomy care, monitoring for complications, and pain management. This level of care is usually within the scope of the registered nurse (RN) rather than a practical nurse (PN).

Choice C rationale:

An older adult who is scheduled for foot amputation due to diabetes complications is likely to have complex care needs, including wound care, diabetes management, and potential complications. This client would require the expertise of an RN rather than a PN.

Choice D rationale:

An adult with alcoholism, cirrhosis, and hepatic encephalopathy may have complex medical and psychosocial issues that require specialized nursing care. This client's condition is not appropriate for a practical nurse (PN) to manage, and the care should be provided by an RN or other specialized healthcare provider.
