Adult Health 2 Final Exam

Correct Answer: A

Rationale: Corrected Rationale: Redness and warmth over the affected area are classic signs of inflammation, which commonly occur in deep vein thrombosis (DVT) due to the obstruction of blood flow. These symptoms result from the body's inflammatory response to the blood clot. Choices B, C, and D are less indicative of DVT. Decreased peripheral pulses may occur in arterial insufficiency rather than DVT. Cyanosis of the toes indicates decreased oxygenation and is more characteristic of arterial issues. Muscle cramps in the calf are nonspecific and can be caused by various conditions, not solely DVT.

Correct Answer: D

Rationale: After reconstitution, the concentration of the cefazolin solution is 400 mg/mL. This calculation is derived by dividing the total milligrams in the vial (1000 mg) by the total volume after reconstitution (2.5 mL). Therefore, each milliliter of the solution contains 400 mg of cefazolin. Choices A, B, and C are incorrect as they do not match the correct calculation based on the information provided.

Correct Answer: B

Rationale: The correct answer is B: 'It ensures clearer imaging by emptying the stomach.' Fasting before an abdominal ultrasound is essential to empty the stomach, allowing for better visualization of the abdominal organs. This improves the quality of the imaging and enhances diagnostic accuracy. Choices A, C, and D are incorrect because reducing intestinal gases, preventing aspiration, and being a standard procedure for surgical interventions are not the primary reasons for fasting before an abdominal ultrasound.

Correct Answer: D

Rationale: When managing hypertension, it is crucial to adopt comprehensive dietary changes. This includes reducing sodium intake to help lower blood pressure, increasing potassium intake to counteract the effects of sodium and help regulate blood pressure, and limiting alcohol consumption as excessive alcohol can raise blood pressure. Therefore, emphasizing all the options provided (A, B, and C) is essential in effectively managing hypertension and reducing overall cardiovascular risk. Choices A, B, and C are not individually sufficient as a single dietary modification but collectively work together to support blood pressure management.

Correct Answer: C

Rationale: The correct intervention for a client experiencing difficulty expectorating thick secretions due to pneumonia is to encourage increased fluid intake. Increasing fluid intake helps to thin secretions, making them easier to expectorate. Administering antibiotics (Choice A) is important in treating pneumonia but does not directly address the issue of thick secretions. Chest physiotherapy (Choice B) may help in some cases, but increasing fluid intake is a more straightforward and effective intervention. Providing humidified oxygen (Choice D) can help with oxygenation but does not directly address the problem of thick secretions.
