1. When a client needs oxygen therapy, what is the highest flow rate that oxygen can be delivered via nasal cannula?

A. 2 liters/minute
B. 4 liters/minute
C. 6 liters/minute
D. 8 liters/minute

Correct answer: C

Rationale: The correct answer is 6 liters/minute. When a client requires oxygen therapy, the maximum flow rate that oxygen can be delivered via nasal cannula is 6 liters/minute. Nasal cannula can effectively deliver oxygen up to 6 liters/minute. Flow rates exceeding 6 liters/minute may lead to drying of the nasal passages and discomfort for the client. Higher flow rates, like 8 liters/minute, should be administered using a mask to ensure sufficient oxygenation. Options A, B, and D are incorrect as they indicate flow rates that surpass the recommended maximum for nasal cannula delivery.

2. A nurse discovers that another nurse has administered an enema to a client even though the client told the nurse that he did not want one. Which is the most appropriate action for the nurse to take?

A. Report the incident to the nursing supervisor
B. Confront the nurse who gave the enema and inform the nurse that she may face charges of battery
C. Tell the client that the nurse did the right thing in giving the enema
D. Contact the client's health care provider

Correct answer: A

Rationale: Battery is any intentional touching of a client without the client's consent, which violates the client's rights. If a nurse discovers such an incident, they should report it to the nursing supervisor. Confronting the nurse and threatening charges of battery could lead to unnecessary conflict. Telling the client that the nurse did the right thing is incorrect as it goes against the client's wishes. While the health care provider may need to be notified eventually, the first step should be reporting the incident to the nursing supervisor to address the violation appropriately.

3. A nursing student is assigned to care for a client who requires a total bed bath. When the student explains to the client that she is going to gather supplies to administer the bath, the client states, 'I don't want a bath. I've been up all night, and I'm clean enough.' The student reports the client's refusal to the nurse. Which action by the nurse is appropriate?

A. Telling the nursing student to persuade the client to have a bath so that the evening shift staff will not have to do it
B. Telling the nursing student to allow the client to rest
C. Telling the client that the refusal of care will be informed to the health care provider
D. Telling the nursing student to give the client the bath anyway

Correct answer: B

Rationale: The client has the right to refuse a treatment or procedure, and if the client does refuse, the nurse must respect the client's decision. Therefore, the nurse would allow the client to rest. Persuading the client to have a bath and giving the bath anyway are both inappropriate as they violate the client's rights. Informing the health care provider of the refusal of care can be discussed with the client if needed, but the immediate action should be to respect the client's wishes and allow them to rest.

4. Which of the following scenarios are considered violations of HIPAA laws?

A. Discussing discharge plans with a client in a multi-bed recovery room with the curtain drawn around the client's bed.
B. Looking up the medical information of a friend without permission.
C. Checking on your spouse's medical record because you are listed as her power of attorney.
D. Avoiding conversations about clients while in line in the cafeteria with a mutual caregiver of that client.

Correct answer: C

Rationale: Scenarios B and C are considered violations of HIPAA laws. Looking up the medical information of a friend who is not in your care, even with permission, is a violation of HIPAA as the friend is not your patient. Checking on your spouse's medical record, even as a power of attorney, is a violation unless it is directly related to caregiving decisions. Discussing discharge plans with a client in a multi-bed recovery room with the curtain drawn around the client's bed is not a violation of HIPAA. This scenario is considered an 'incidental disclosure' and is not a breach of HIPAA privacy rules. Avoiding conversations about clients while in line in the cafeteria with a mutual caregiver of that client is actually a good practice as it maintains client confidentiality.

5. Which of the following neurological disorders is characterized by writhing, twisting movements of the face and limbs?

A. epilepsy
B. Parkinson's
C. multiple sclerosis
D. Huntington's chorea

Correct answer: D

Rationale: Huntington's chorea is characterized by writhing, twisting movements of the face and limbs, known as chorea. This disorder is caused by a genetic mutation affecting specific brain cells. Epilepsy presents with seizures, Parkinson's with tremors and rigidity, and multiple sclerosis with central nervous system issues. The specific description of writhing and twisting movements aligns with Huntington's chorea, making it the correct answer. Choices A, B, and C are incorrect as they describe different neurological disorders with distinct symptoms that do not match the writhing, twisting movements characteristic of Huntington's chorea.
