Nursing Elites

1. Which diagnostic test is used to confirm tuberculosis (TB) infection?

• A. Chest X-ray
• B. Sputum culture
• C. Skin test (Mantoux)
• D. MRI

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.

2. A client with chronic kidney disease is being taught by a nurse about managing protein intake. Which of the following instructions should the nurse include?

• A. You should increase your intake of high-protein foods.
• B. You should limit your intake of high-protein foods.
• C. You should avoid all protein sources to prevent further kidney damage.
• D. You should increase your intake of animal protein.

Correct answer: B

Rationale: The correct answer is B: 'You should limit your intake of high-protein foods.' Clients with chronic kidney disease should restrict their intake of high-protein foods to lessen the workload on the kidneys and prevent further kidney damage. Option A is incorrect as increasing intake of high-protein foods can exacerbate the condition. Option C is incorrect as avoiding all protein sources is not advisable, as some proteins are essential for overall health. Option D is incorrect as increasing the intake of animal protein can put more strain on the kidneys due to the metabolites produced during protein breakdown.

3. A healthcare professional is reviewing the laboratory values of a client who has cirrhosis. Which of the following findings should the healthcare professional report to the provider?

• A. Ammonia 75 mcg/dL
• B. Sodium 142 mEq/L
• C. Calcium 9.5 mg/dL
• D. Bilirubin 2.5 mg/dL

Correct answer: D

Rationale: An elevated bilirubin level in clients with cirrhosis indicates worsening liver function and potential complications. It is crucial to report this finding promptly as it may require immediate medical intervention. Elevated ammonia levels (choice A) are also concerning in cirrhosis, indicating hepatic encephalopathy, but bilirubin levels are more specific to liver function in this context. Choices B and C are within normal ranges and are not typically of immediate concern in cirrhosis.

4. What is the best intervention for a patient with dehydration?

• A. Administer IV fluids
• B. Provide oral fluids
• C. Encourage fluid intake
• D. Administer electrolytes

Correct answer: A

Rationale: Administering IV fluids is the best intervention for a patient with dehydration because it is the fastest and most effective way to rehydrate the body. IV fluids can quickly restore fluid volume and electrolyte balance in severe cases of dehydration. Providing oral fluids or encouraging fluid intake may not be sufficient for patients with moderate to severe dehydration, as they may have impaired gastrointestinal absorption. While electrolytes are essential for rehydration, administering them alone without fluid replacement may not address the primary issue of fluid loss in dehydration.

5. What is the primary action when caring for a patient with a stage 3 pressure ulcer?

• A. Apply a hydrocolloid dressing
• B. Provide wound debridement
• C. Change the dressing daily
• D. Apply moist gauze to the ulcer

Correct answer: A

Rationale: The correct answer is to apply a hydrocolloid dressing. This type of dressing helps maintain a moist environment that is conducive to healing in stage 3 pressure ulcers. Providing wound debridement (choice B) is more suitable for higher stages of pressure ulcers where there is necrotic tissue. Changing the dressing daily (choice C) may be necessary but is not the primary action for a stage 3 pressure ulcer. Applying moist gauze (choice D) is not the recommended approach as it does not provide the same benefits as a hydrocolloid dressing.
