ATI RN Custom Exams Set 2

Correct Answer: C

Rationale: The correct answer is C: 'Maintain the health of the Army and preserve its combat effectiveness.' This mission statement reflects the primary goal of the Army Medical Department, which is to ensure that military personnel remain healthy and fit for duty to preserve the Army's fighting strength. Choices A, B, and D are incorrect because they do not capture the core purpose of the Army Medical Department, which is focused on the health and readiness of the military forces, rather than performing annual physical examinations, responding to disasters, or providing education and training.

Correct Answer: D

Rationale: The correct answer is Vitamin K. Prolonged antibiotic use can disrupt the gut flora, leading to Vitamin K deficiency and an increased risk of bleeding. Vitamin A deficiency is not commonly associated with antibiotic use. Similarly, Vitamin B6 and Vitamin C deficiencies are not typically linked to prolonged antibiotic use.

Correct Answer: D

Rationale: In situations where a client is unable to sign the consent form, obtaining a telephone consent from a family member witnessed by two healthcare providers is the appropriate action to ensure informed consent is obtained. Option A is not necessary and involves legal proceedings. Option B is not ethical as the nurse cannot sign the consent on behalf of the client. Option C is unsafe and violates the client's rights by proceeding without proper consent.

Correct Answer: B

Rationale: Clients who smoke require more vitamin C due to increased oxidative stress and depletion of vitamin C. Smoking leads to higher levels of oxidative stress in the body, which in turn increases the utilization of vitamin C to counteract the damage caused by free radicals. Choices A, C, and D do not directly impact the body's need for vitamin C as smoking does.

Correct Answer: D

Rationale: The correct answer is to administer the Coumadin along with the heparin drip as ordered. Heparin and warfarin are often given together initially because warfarin takes a few days to become effective. Discontinuing the heparin drip before initiating Coumadin can increase the risk of clot formation. Checking the client's INR before starting Coumadin is important but not the immediate action required. Clarifying the order with the healthcare provider is not necessary as both medications are commonly used together.
