ATI Exit Exam RN

Correct Answer: C

Rationale: The Mantoux skin test, also known as the Tuberculin Skin Test (TST), is used to confirm tuberculosis (TB) infection. This test involves injecting a small amount of tuberculin protein derivative under the top layer of the skin and then evaluating the immune system's response to the protein. A positive reaction indicates exposure to the TB bacteria. Chest X-rays are used to detect abnormalities in the lungs caused by TB but are not confirmatory. Sputum culture is used to identify the presence of TB bacteria in the sputum. MRIs are not typically used as a primary diagnostic tool for TB.

Correct Answer: D

Rationale: Ambulating the client on the first postoperative day is crucial to prevent complications like deep vein thrombosis and aid in the recovery process. Elevating the legs while in bed can help with circulation but is not as effective in preventing complications related to immobility post-surgery. Repositioning every 2 hours is important for preventing pressure ulcers but does not directly address postoperative care. Maintaining bed rest for the first 24 hours postoperatively can increase the risk of complications associated with immobility, making early ambulation a more appropriate intervention.

Correct Answer: C

Rationale: When administering enoxaparin for the prevention of DVT, the nurse should inject the medication into the lateral abdominal wall. This site is preferred for subcutaneous injections of enoxaparin to reduce the risk of bleeding or injury. Expelling air bubbles, massaging the injection site, or administering an NSAID for discomfort are not appropriate actions and could lead to complications or ineffective medication delivery.

Correct Answer: A

Rationale: The best method to monitor fluid balance in a patient receiving diuretics is to monitor daily weight. Daily weighing is a precise way to assess changes in fluid status as it reflects variations in total body water. Monitoring intake and output (choice B) is also important but may not provide as accurate a measurement as daily weight. Monitoring blood pressure (choice C) is essential but does not directly measure fluid balance. Monitoring edema (choice D) is helpful to assess fluid status visually but may not be as sensitive as daily weight measurements in detecting subtle changes in fluid balance.

Correct Answer: A

Rationale: The correct answer is to administer IV fluids. This intervention is the priority as it helps rapidly restore hydration in patients with dehydration by delivering fluids directly into the bloodstream. Monitoring intake and output (choice B) is important but comes after providing immediate fluid resuscitation. Administering oral fluids (choice C) may not be sufficient for a patient with dehydration who requires rapid rehydration. Providing electrolyte replacement (choice D) is essential but often follows fluid resuscitation to correct any electrolyte imbalances resulting from dehydration.
