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. The family of a patient who is receiving therapeutic hypothermia states they do not understand why the patient is being kept so cold. What objective information can you provide to help address their concerns?

• A. Let them talk to another patient who has had the same therapy
• B. Provide research-based information about therapeutic hypothermia
• C. Connect them with the nurse manager
• D. Call the physician and ask him to talk to the family

Correct answer: B

Rationale: Providing research-based information about the benefits of therapeutic hypothermia for their loved one will provide evidence that this is an established therapy with generally positive outcomes. Families are certainly not expected to be familiar with critical care interventions, and their concerns should be addressed with evidence-based data whenever possible. Option A is not appropriate as sharing patient information violates privacy laws and does not address the family's concerns directly. Option C may not directly provide the detailed information the family needs to understand therapeutic hypothermia. Option D involves unnecessary escalation by immediately involving the physician, when providing education and information should be the initial step in addressing the family's concerns.

3. What is the purpose of performing quality control?

• A. Create a paper trail to show that the laboratory is compliant with OSHA standards for quality control.
• B. Improve the odds that the results reported for any given test are as accurate and reliable as possible.
• C. Be required by law to be part of a quality assurance program.
• D. All of the above

Correct answer: B

Rationale: The primary purpose of performing quality control is to enhance the accuracy and reliability of test results. Quality controls are crucial for ensuring the reliability of each analyte tested. While quality control is not mandated by specific laws, accrediting bodies often require it to maintain accreditation. Creating a paper trail and legal requirements are not the primary objectives of quality control, making choices A and C incorrect. Therefore, the correct answer is to improve the accuracy and reliability of reported test results.

4. After a lengthy explanation of a medical procedure, the patient asks many questions. The physician answers all of the questions to the best of their ability. The patient then gives consent for treatment. The costly equipment and supplies are put into place, and the patient is prepared. Two minutes before the procedure is to start, the patient begins panicking and changes their mind. Which of the following situations would be the best way to avoid litigation?

• A. Document that the patient originally gave consent and proceed if the benefits of the procedure outweigh the patient's wishes.
• B. Have the patient sign a form stating that they are refusing consent. If they refuse to sign, do not proceed with the procedure.
• C. Repeat the explanation of the procedure until the patient understands that having the procedure done is the best form of treatment. Do not proceed with the procedure.
• D. Do not proceed. Document the patient's refusal, have the patient sign a refusal to consent to treatment. If the patient refuses to sign the form, have a witness available to sign.

Correct answer: D

Rationale: In this scenario, the best course of action to avoid litigation is to respect the patient's right to refuse treatment, especially when changing their mind before the procedure starts. By not proceeding with the treatment, documenting the patient's refusal, and having the patient sign a refusal to consent form, you are following proper ethical and legal procedures. If the patient refuses to sign the form, having a witness available to sign further strengthens the documentation of the patient's decision. This approach ensures that the patient's autonomy and right to make informed decisions about their healthcare are respected. Choices A, B, and C do not prioritize the patient's right to refuse treatment and could potentially lead to legal issues if treatment is carried out against the patient's wishes.

5. A client has started sweating profusely due to intense heat. His overall luid volume is low and he has developed electrolyte imbalance. This client is most likely suffering from:

• A. Malignant hyperthermia
• B. Heat exhaustion
• C. Heat stroke
• D. Heat cramps

Correct answer: B

Rationale: Heat exhaustion occurs when a person has enough diaphoresis that he becomes dehydrated. Intense sweating can cause both luid and electrolyte imbalances. Untreated heat exhaustion can lead to heat stroke, which results in organ damage, loss of consciousness, or death.
