1. Which of the following lab values is associated with a decreased risk of cardiovascular disease?

A. high HDL cholesterol
B. low HDL cholesterol
C. low total cholesterol
D. low triglycerides

Correct answer: B

Rationale: High HDL cholesterol is associated with a decreased risk of cardiovascular disease because HDL cholesterol is known as 'good' cholesterol. It helps remove other forms of cholesterol, like LDL cholesterol, from the bloodstream, reducing the risk of plaque buildup in the arteries. Low HDL cholesterol (Choice B) is actually a risk factor for cardiovascular disease because it means there is less of the 'good' cholesterol to perform its protective functions. Low total cholesterol (Choice C) and low triglycerides (Choice D) are not necessarily associated with a decreased risk of cardiovascular disease, as the balance and types of cholesterol play a more crucial role in heart health.

2. Which of the following statements from a client may indicate that they are at a higher risk for a fall?

A. "I would like to get out of bed but would like to put on my non-skid socks first."?
B. "Can you make sure the two bedrails are raised before leaving the room?"?
C. "I think I'm ready to walk a longer distance with the cane today."?
D. "I need to get out of bed to go to the bathroom now. I cannot find my glasses but cannot wait."?

Correct answer: D

Rationale: The correct answer is 'I need to get out of bed to go to the bathroom now. I cannot find my glasses but cannot wait.' This statement indicates that the client is in a hurry and unable to find their glasses, which could increase the risk of a fall due to impaired vision. Choice A about putting on non-skid socks shows the client's awareness of fall prevention, reducing the risk. Choice B demonstrates the client's request for bedrails to be raised, which is a safety measure, reducing the risk as well. Choice C suggests the client's readiness to walk a longer distance with a cane, indicating progress in mobility but not necessarily a higher fall risk.

3. A health care provider repeatedly asks a nurse to write his verbal prescriptions in his clients' charts after he makes his rounds. The nurse is uncomfortable with writing the prescriptions and explains this to the health care provider, but the health care provider tells the nurse that she will be reported if she does not write the prescriptions. How should the nurse manage this conflict?

A. Stating to the health care provider, 'I don't really care whether you report me. I am not writing your prescriptions.'
B. Fulfilling the health care provider's request
C. Discussing the situation with the nurse manager
D. Reporting the health care provider to the chief of medicine at the hospital

Correct answer: C

Rationale: When a conflict arises, it is most appropriate to try resolving the conflict directly. In this situation, the nurse has tried to explain why she is uncomfortable with the health care provider's request but has been unable to resolve the conflict. The nurse would then most appropriately use organizational channels of communication and discuss the issue with the nurse manager, who would then proceed to resolve the conflict. The nurse manager may attempt to discuss the situation with the health care provider or seek assistance from the nursing supervisor. Fulfilling the health care provider's request and writing the prescriptions in the clients' charts ignores the issue. Reporting the health care provider to the chief of medicine is inappropriate because the nurse should use the appropriate organizational channels of communication to resolve the conflict. Stating 'I don't really care whether you report me. I am not writing your prescriptions.' is an inappropriate statement and will result in further conflict between the nurse and health care provider.

4. A nurse calls a health care provider to report that a client with congestive heart failure (CHF) is exhibiting dyspnea and worsening of wheezing. The health care provider, who is in a hurry because of a situation in the emergency department, gives the nurse a telephone prescription for furosemide (Lasix) but does not specify the route of administration. What is the appropriate action on the part of the nurse?

A. Calling the health care provider who gave the telephone prescription to clarify the prescription
B. Administering the medication orally and clarifying the prescription once the health care provider has finished caring for the client in the emergency department
C. Calling the nursing supervisor for assistance in determining the route of administration
D. Administering the medication intravenously because this route is generally used for clients with CHF

Correct answer: A

Rationale: Telephone prescriptions involve a health care provider dictating a prescribed therapy over the telephone to the nurse. The nurse must clarify the prescription by repeating it clearly and precisely to the health care provider. The nurse then writes the prescription on the health care provider's prescription sheet or enters it into the electronic medical record. It is crucial not to interpret an unclear prescription or administer a medication by a route that has not been expressly prescribed. In this case, the nurse should call the health care provider who gave the telephone prescription to clarify the prescription, ensuring the correct route of administration is specified. Options B, C, and D are incorrect because administering the medication without clarification, seeking assistance from the nursing supervisor, or choosing an arbitrary route of administration can compromise patient safety and violate medication administration protocols.

5. What information does the healthcare provider remember regarding do-not-resuscitate (DNR) orders in this scenario?

A. That a DNR order may be written by a healthcare provider
B. That everything possible must be done if the client stops breathing
C. That medications only may be given to the client if the client stops breathing
D. That life support measures will have to be implemented if the client stops breathing

Correct answer: A

Rationale: In a situation where a client has no family members and the client's wife is mentally incompetent, the healthcare provider may write a DNR order if it is deemed medically certain that resuscitation would be futile. A DNR order is a medical directive that instructs healthcare providers not to perform CPR if a patient's heart stops or if the patient stops breathing. Option A is correct because a DNR order can indeed be issued by a healthcare provider under certain circumstances, as it is a medical decision. Options B, C, and D are incorrect as they do not accurately reflect the concept of DNR orders and the decision-making process involved in such situations.
