Employers are required to test staff members for the following:

Correct Answer: B

Rationale: Step-by-step rationale for why the correct answer (B) is Tuberculosis: 1. Tuberculosis is an infectious disease that can spread in workplaces. 2. Employers have a duty to protect the health and safety of employees. 3. Testing for tuberculosis helps in early detection and prevention of its spread. 4. Screening for tuberculosis is a common practice in healthcare and high-risk environments. Summary: - A: Sexually-transmitted infections are not typically mandated for workplace testing. - C: Cancer is not infectious and does not pose a direct risk to coworkers. - D: HIV/AIDS testing may be required in certain healthcare settings, but tuberculosis testing is more common in workplaces.

Correct Answer: C

Rationale: The correct answer is C: Complete an addendum, and return to the hospital to add it to the report. This is the most appropriate action as it ensures the patient's information is accurately documented. By completing an addendum and returning to the hospital, you can update the patient care report with the missing information in a timely manner. This helps maintain the integrity of the patient record and ensures continuity of care. Option A is not the best choice as documenting the information on the back of the original patient care report may not be considered a formal and standardized way of updating the report, which could lead to issues with clarity and organization. Option B involves contacting the emergency department staff, which is a good step, but it does not address the issue of updating the patient care report itself. Option D is incorrect because simply leaving a copy of the patient care report at the hospital does not resolve the issue of missing important patient information. Ignoring the mistake could lead to potential errors in future patient care or legal

Correct Answer: D

Rationale: The correct answer is D: Cuffed 7-8 mm endotracheal tube. This size provides a balance between being large enough to secure the airway and small enough to pass through the nasal passage comfortably. The cuff helps to prevent air leakage and aspiration. A cuffed tube is essential for positive pressure ventilation and preventing gastric insufflation. Choices A and C are too narrow for an adult, risking airway obstruction and difficulty with ventilation. Choice B, an uncuffed tube, may not provide a secure airway and could lead to air leakage and aspiration.

Correct Answer: B

Rationale: Correct Answer: B Rationale: 1. Hypovolemia leads to decreased blood volume and potential hypothermia. 2. Administering warm normal saline helps prevent further decrease in body temperature. 3. Maintaining normal body temperature is crucial for optimal cellular function and metabolism. 4. Warm saline infusion supports the body's efforts to regulate temperature and prevent complications. Summary: A: Warm saline does not directly affect oxygen transport; oxygen binds to hemoglobin in red blood cells. C: Energy required for saline to enter circulation is not significantly impacted by its temperature. D: Cardiac output is influenced by various factors, but warming saline does not directly increase it.

Correct Answer: C

Rationale: Rationale: C: Losartan is an angiotensin II receptor blocker used to prevent blood clot formation in a-fib/pulmonary embolism, decrease MI risk in atherosclerosis, and reduce stroke risk by lowering blood pressure and improving cardiovascular outcomes. Incorrect choices: A: Nitroglycerin is a vasodilator used for angina but does not prevent blood clot formation or reduce stroke risk. B: Lotensin is an ACE inhibitor for hypertension, not specifically for preventing blood clots or reducing stroke risk. D: Streptokinase is a thrombolytic agent used to dissolve blood clots, not prevent their formation.
