Adult Health 2 Final Exam

Correct Answer: D

Rationale: Assessing the client's lung sounds is the most appropriate initial action when a postoperative client complains of sudden shortness of breath. This step helps the nurse evaluate the respiratory status and detect abnormalities such as decreased breath sounds or crackles, which could indicate a serious condition like a pulmonary embolism. Administering oxygen (Choice A) may be necessary but should come after assessing the lung sounds to ensure the appropriate intervention. Calling the healthcare provider (Choice B) or preparing for a chest x-ray (Choice C) can be important subsequent actions based on the findings from the lung sound assessment, but they are not the first priority in this situation.

Correct Answer: A

Rationale: After reconstitution, the concentration of cefazolin solution is calculated by dividing the total amount of drug (600 mg) by the total volume after reconstitution (2.5 mL). This gives 600 mg / 2.5 mL = 240 mg/mL. However, the question asks for the concentration in each milliliter of solution after reconstitution, so we need to consider the final volume of 2.5 mL. Therefore, 240 mg/mL * 2.5 mL = 600 mg, which means each milliliter contains 240 mg of cefazolin. Therefore, after reconstitution, there are 400 mg of cefazolin in each milliliter of solution. Choices B, C, and D are incorrect as they do not accurately reflect the concentration after reconstitution.

Correct Answer: C

Rationale: The correct answer is C. Substance abuse, particularly using shared inhalation equipment like needles and pipes for drug inhalation, significantly increases the risk of contracting HIV. Choice A, the 17-year-old with multiple sexual partners, poses a risk of HIV transmission through sexual contact, but it is lower compared to the direct risk associated with sharing drug paraphernalia. Choice B, the 34-year-old homosexual in a monogamous relationship, is at lower risk since being in a monogamous relationship reduces exposure to HIV. Choice D, the 45-year-old who received blood transfusions, is also at lower risk as blood transfusions are now screened for HIV, decreasing the likelihood of transmission through this route.

Correct Answer: C

Rationale: The correct answer is to notify the surgeon. Redness and swelling at a wound site can indicate an infection, which may require medical intervention. Applying an ice pack (choice A) is not appropriate without further assessment. While documenting the findings and monitoring (choice B) is important, it should be accompanied by notifying the surgeon for further evaluation. Cleaning the wound with sterile saline (choice D) may not be sufficient if an infection is present, so immediate communication with the surgeon is crucial.

Correct Answer: A

Rationale: The correct first action for a client with a cast experiencing numbness and tingling in the affected limb is to check for tightness of the cast. Numbness and tingling can indicate compromised circulation, and a tight cast may be causing this. Checking the cast for tightness is essential to ensure it is not impeding circulation. Elevating the limb, applying ice, or notifying the physician can be subsequent actions depending on the assessment findings after checking the cast. Elevating the limb might help improve circulation, applying ice is not indicated for numbness and tingling, and notifying the physician can be done if the issue persists after addressing the immediate concern of cast tightness.
