Nclex Exam Cram Practice Questions

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. All of the following clients are in need of an emergency assessment except:

A. a bleeding client who has an injury from falling debris.
B. an unresponsive client.
C. a client with an old injury.
D. a pregnant woman with imminent delivery.

Correct answer: C

Rationale: The correct answer is 'a client with an old injury.' Emergency assessments are required for immediate and life-threatening situations. Clients A, B, and D are in need of emergency assessments due to their critical conditions. Choice C, a client with an old injury, does not require an emergency assessment as it is not an acute or life-threatening situation. While the client with an old injury may still need medical attention, it does not necessitate an emergency assessment as the condition is not currently life-threatening or in need of immediate intervention.

3. How should an infant be secured in a car?

A. To hold the infant while sitting in the middle of the back seat of the car
B. To place the infant in the front seat in a rear-facing infant safety seat if the car has passenger-side air bags
C. To place the infant in a booster seat in the front seat with the shoulder and lap belts secured around the infant
D. To secure the infant in the middle of the back seat in a rear-facing infant safety seat

Correct answer: D

Rationale: The recommended way to secure an infant in a car is to place them in the middle of the back seat in a rear-facing infant safety seat. Option A is incorrect because infants should never be held while in a moving vehicle due to safety concerns. Option B is incorrect because placing an infant in the front seat with a rear-facing safety seat can be risky if the car has passenger-side airbags. Option C is incorrect as booster seats are not suitable for infants. Therefore, the correct choice is to secure the infant in the middle of the back seat in a rear-facing infant safety seat.

4. In which situation is the nurse upholding the ethical principle of fidelity?

A. Providing complete information regarding treatment options to a client with newly diagnosed cancer
B. Allowing a client to decide when to receive daily hygiene care
C. Inserting a 19-gauge intravenous catheter into a client requiring a blood transfusion
D. Contacting the health care provider about the client's request to incorporate complementary therapies for pain into the treatment plan

Correct answer: D

Rationale: Fidelity is the ethical principle of keeping promises made to clients, families, and other healthcare professionals. Contacting the health care provider about the client's request to incorporate complementary therapies for pain into the treatment plan exemplifies fidelity. By advocating for the client's preferences and ensuring their requests are addressed, the nurse demonstrates a commitment to fulfilling promises made to the client. Allowing a client to decide when to receive daily hygiene care relates to respecting autonomy, not fidelity. Inserting a 19-gauge intravenous catheter into a client needing a blood transfusion aligns with beneficence, as it involves taking action to provide necessary treatment. Providing complete information to a client with newly diagnosed cancer about treatment options reflects justice, promoting fairness and equity in healthcare by offering equal access to information and treatment choices.

5. When caring for clients with Buck’s Traction, the major areas of importance should be:

A. nutrition, elimination, comfort, safety
B. ROM exercises, transportation
C. nutrition, elimination, comfort, safety
D. elimination, safety, isotonic exercises

Correct answer: C

Rationale: When caring for clients with Buck’s Traction, the major areas of importance should be nutrition, elimination, comfort, and safety. Proper nutrition, including a diet high in protein with adequate fluids, is essential for healing and recovery. Elimination refers to maintaining regular bowel and bladder function. Comfort is crucial to ensure the patient's well-being while in traction, and safety measures should be followed to prevent complications. Choices A, B, and D are incorrect. ROM exercises are not typically a primary concern with Buck’s Traction, making choices A and B incorrect. Isotonic exercises are not specifically related to the care of a client in Buck's Traction, making choice D incorrect.
