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. How should a healthcare provider monitor a patient receiving heparin therapy?
- A. Monitor aPTT
- B. Monitor platelet count
- C. Monitor sodium levels
- D. Monitor calcium levels
Correct answer: A
Rationale: The correct answer is to monitor aPTT (activated partial thromboplastin time) when a patient is receiving heparin therapy. aPTT monitoring is essential for assessing the therapeutic effectiveness of heparin, ensuring the patient is within the desired therapeutic range to prevent both clotting and bleeding. Monitoring platelet count (Choice B) is important for assessing for heparin-induced thrombocytopenia but is not the primary monitoring parameter for heparin therapy. Monitoring sodium levels (Choice C) and calcium levels (Choice D) are not directly related to assessing the therapeutic effectiveness or potential side effects of heparin therapy.
3. A nurse is teaching a client who has chronic kidney disease about managing protein intake. Which of the following statements should the nurse include in the teaching?
- A. You should consume more plant-based protein.
- B. You should increase your intake of animal protein.
- C. You should increase your intake of high-protein foods.
- D. You should limit your intake of high-protein foods.
Correct answer: D
Rationale: The correct answer is D: "You should limit your intake of high-protein foods." Clients with chronic kidney disease should reduce their intake of high-protein foods to lessen the workload on the kidneys and prevent further kidney damage. Choices A, B, and C are incorrect because increasing intake of either plant-based or animal protein or high-protein foods can exacerbate kidney issues in individuals with chronic kidney disease.
4. What is the best initial action when a patient presents with confusion?
- A. Administer IV fluids
- B. Perform a neurological assessment
- C. Administer electrolytes
- D. Prepare for a CT scan
Correct answer: B
Rationale: When a patient presents with confusion, the best initial action is to perform a neurological assessment. This assessment helps in identifying potential causes of confusion such as neurological issues, infections, metabolic abnormalities, or medication side effects. Administering IV fluids (Choice A) may be necessary based on assessment findings, but it is not the first step. Administering electrolytes (Choice C) would also depend on the assessment results. Preparing for a CT scan (Choice D) may be indicated later in the diagnostic process but is not the initial action when a patient presents with confusion.
5. A healthcare professional is reviewing the laboratory results of a client who has rheumatoid arthritis. Which of the following findings should be reported to the provider?
- A. WBC count 8,000/mm3
- B. Platelets 150,000/mm3
- C. Aspartate aminotransferase 10 units/L
- D. Erythrocyte sedimentation rate 75 mm/hr
Correct answer: D
Rationale: The correct answer is D. A high erythrocyte sedimentation rate (ESR) of 75 mm/hr indicates inflammation, which is common in rheumatoid arthritis. Elevated ESR levels are often seen in inflammatory conditions like rheumatoid arthritis. Options A, B, and C are within the normal range and are not typically indicative of active inflammation associated with rheumatoid arthritis. Therefore, the nurse should report the elevated ESR level to the provider for further evaluation and management.
