Adult Health 2 Final Exam

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: A

Rationale: The correct answer is A, Vastus Lateralis. The vastus lateralis site is recommended for IM injections in small children due to its large muscle mass, making it suitable for injections in pediatric patients. Choices B, C, and D are incorrect. The radial artery is not a site for IM injections; it is a site for arterial puncture. The dorsogluteal site is not recommended for children due to potential risks, such as injury to the sciatic nerve. The rectus femoris is not typically used for IM injections in children, as other sites like the vastus lateralis are more commonly preferred.

Correct Answer: B

Rationale: The correct answer is B: 'Monitor sodium intake.' Sodium levels can affect lithium levels in the body, so it is crucial to maintain a consistent sodium intake to prevent toxicity or subtherapeutic levels. Option A is incorrect because lithium is usually recommended to be taken on an empty stomach to enhance absorption. Option C, reporting signs of weight gain, is relevant but not as critical as monitoring sodium intake. Option D, avoiding excessive caffeine intake, is important for some individuals but not as essential as monitoring sodium levels when taking lithium.

Correct Answer: D

Rationale: Administering prescribed antibiotics is crucial in treating MRSA infections. MRSA is a type of bacteria that is resistant to many antibiotics, including methicillin. Therefore, prompt administration of the appropriate antibiotics is essential to target the MRSA infection effectively. Encouraging increased oral fluids (Choice A) and providing high-protein snacks (Choice B) may be beneficial for overall recovery but are not the most important actions in treating an MRSA infection. Changing the wound dressing (Choice C) is important for wound care but does not directly address the infection caused by MRSA.

Correct Answer: B

Rationale: The correct answer is to ensure the catheter bag is always below bladder level. This positioning helps prevent backflow of urine, reducing the risk of CAUTIs. Choice A, irrigating the catheter daily, is not recommended as it can introduce pathogens into the bladder. Changing the catheter too frequently (Choice C) can increase the risk of introducing pathogens. Administering prophylactic antibiotics (Choice D) is not the primary intervention for preventing CAUTIs and can lead to antibiotic resistance.
