An unresponsive male victim of a diving accident is brought to the emergency department where it is determined that immediate surgery is required to save his life.

The client is accompanied by a close friend, but no family members are available.

Which action should the nurse take first?

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:

Fresh or frozen vegetables without sauce. Rationale: Fresh or frozen vegetables without sauce are excellent choices for a client with hypertension. These foods are low in sodium and can help manage blood pressure effectively. The absence of added sauces ensures that there is no hidden sodium content.

Choice B rationale:

Fruits without sauce. Rationale: Fruits without sauce are also suitable for clients with hypertension. They are naturally low in sodium and provide essential nutrients that can support blood pressure control. The absence of sauce ensures that no additional sodium is added.

Choice C rationale:

Pickled olives. Rationale: Pickled olives are high in sodium due to the pickling process. Therefore, they are not recommended for clients with hypertension as they can lead to an increase in blood pressure.

Choice D rationale:

Canned soup. Rationale: Canned soup often contains high levels of sodium, which is not suitable for clients with hypertension. Excessive sodium intake can contribute to elevated blood pressure and should be avoided.

Choice E rationale:

Cottage cheese. Rationale: Cottage cheese is generally considered acceptable for clients with hypertension, especially if it is the low-sodium or reduced-sodium variety. However, it is not as strongly recommended as fresh or frozen vegetables and fruits without sauce.
