Adult Health 2 Final Exam Questions
Question 1 of 5
When reconstituted, how many milligrams are in each milliliter of solution?
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.
Question 2 of 5
In a community health setting, which individual is at highest risk for contracting an HIV infection?
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.
Question 3 of 5
A client with a history of congestive heart failure is prescribed digoxin (Lanoxin). Which assessment is most important for the nurse to obtain before administering this medication?
Correct Answer: B
Rationale: The correct answer is B: Heart rate. Before administering digoxin to a client with a history of congestive heart failure, the nurse must assess the client's heart rate. Digoxin can cause bradycardia, so monitoring the heart rate is crucial to prevent potential complications. Assessing blood pressure, respiratory rate, and oxygen saturation are important assessments but are not as directly influenced by digoxin as heart rate is in this scenario. Blood pressure can be affected by various factors, including dehydration or other medications. Respiratory rate and oxygen saturation are more related to respiratory function and gas exchange, which are not the primary concerns when administering digoxin to a client with heart failure.
Question 4 of 5
A client with a diagnosis of deep vein thrombosis (DVT) is receiving anticoagulant therapy. Which instruction should the nurse provide to the client?
Correct Answer: B
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 5 of 5
A client who has just been diagnosed with tuberculosis (TB) is being discharged home. Which instruction is most important for the nurse to provide?
Correct Answer: B
Rationale: The correct answer is B: 'Take all prescribed medications as directed.' This instruction is the most important because adherence to the prescribed medication regimen is crucial in treating tuberculosis effectively and preventing the development of drug-resistant TB. While choice A is important for infection control, ensuring treatment adherence through proper medication intake takes precedence. Choice C is also essential for monitoring progress but is not as critical as ensuring medication compliance. Choice D is relevant for preventing transmission but is not as crucial as ensuring proper treatment by taking medications as directed.
