Nursing Elites

1. A client must use a non-rebreathing oxygen mask. Which of the following statements is true regarding this type of mask?

• A. A non-rebreather can provide an FiO2 of 40%.
• B. A client should breathe through his or her mouth when using a non-rebreather.
• C. A non-rebreather offers a reservoir from which the client inhales.
• D. The mask of a non-rebreather should be changed every 3 hours.

Correct answer: A

Rationale: A non-rebreather mask is used for supplemental oxygen delivery for clients experiencing breathing difficulties. The non-rebreather mask includes a one-way valve that allows exhaled air to escape, preventing the rebreathing of carbon dioxide. The client inhales oxygenated air from a reservoir bag attached to the mask, providing high-concentration oxygen therapy. A non-rebreather mask can deliver FiO2 levels of up to 90%, making it an effective intervention for clients requiring high oxygen concentrations. Therefore, the statement that 'A non-rebreather can provide an FiO2 of 40%' is correct. Choices B, C, and D are incorrect because clients should breathe through their nose and mouth, the mask offers a reservoir for inhaling oxygen, and the mask should be assessed and potentially replaced if soiled or damaged, not routinely changed every 3 hours.

2. An occupational health nurse works at a manufacturing plant where there is potential exposure to inhaled dust. Which action, if recommended by the nurse, will be most helpful in reducing the incidence of lung disease?

• A. Treat workers with pulmonary fibrosis.
• B. Teach about symptoms of lung disease.
• C. Require the use of protective equipment.
• D. Monitor workers for coughing and wheezing.

Correct answer: C

Rationale: Prevention of lung disease requires the use of appropriate protective equipment such as masks to reduce exposure to inhaled dust, which is a significant risk factor for lung disease. Teaching about symptoms of lung disease, treating workers with pulmonary fibrosis, and monitoring for coughing and wheezing are important actions for early recognition and treatment of lung disease. However, the most effective strategy to prevent lung damage in this scenario is to require the use of protective equipment to minimize exposure to harmful substances.

3. Which of the following situations warrants a measurement for orthostatic hypotension?

• A. A 36-year-old male with a spinal injury
• B. An 86-year-old female with significantly altered mental status
• C. A 58-year-old female with near-syncope
• D. A 41-year-old male with acute deep vein thrombosis

Correct answer: C

Rationale: The correct answer is a 58-year-old female with near-syncope. Orthostatic hypotension is a drop in blood pressure of greater than 20 mmHg systolic when moving from a sitting or lying position to standing. Patients at higher risk include those with syncope or near-syncope, symptomatic hypovolemia, and those prone to falls. The other choices are less likely to present with orthostatic hypotension. A spinal injury, altered mental status, and acute deep vein thrombosis are not directly associated with the immediate need for orthostatic hypotension measurement.

4. Your patient has been diagnosed with herpes simplex virus 2. Which of the following would NOT be included in your teaching of this patient?

• A. If you have symptoms, you should avoid sexual contact with other individuals.
• B. With treatment, this condition can be cured.
• C. This disease is highly contagious.
• D. You may experience tingling in the skin before an active outbreak occurs.

Correct answer: B

Rationale: The correct answer is 'With treatment, this condition can be cured.' The treatment for herpes simplex virus (HSV) is symptomatic and palliative, aimed at managing symptoms rather than curing the infection. HSV is highly contagious, so sexual contact should be avoided during active outbreaks to prevent transmission. Many patients experience a tingling sensation in the skin before an active outbreak, known as a prodrome. Educating the patient that the condition is not curable but manageable with treatment is vital to set realistic expectations and promote proper management of the disease.

5. OSHA has very strict standards for hospital employees who may encounter hazardous materials or patients who have been exposed to them. These regulations include all of the following EXCEPT:

• A. Respiratory protection must be provided to all employees who might be exposed.
• B. Training on respiratory protection must be provided.
• C. Employers must provide personal protective equipment to all employees.
• D. All ED personnel must be trained in decontamination procedures.

Correct answer: D

Rationale: OSHA regulations for hospital employees dealing with hazardous materials or exposed patients require respiratory protection for potentially exposed employees, training on respiratory protection, and the provision of personal protective equipment. However, not all ED personnel are required to be trained in decontamination procedures. While all ED staff should have a basic understanding of hazmat situations, specific training in decontamination procedures is only necessary for those who will be directly involved in the decontamination process. Therefore, the correct answer is that all ED personnel must be trained in decontamination procedures, as this is not a mandatory requirement under OSHA regulations for hospital employees who may encounter hazardous materials or exposed patients.
