NCLEX Practice Test: Video 2 Answers (25 Questions)

Question 1

The primary purpose for using a CPM machine for the client with a total knee repair is to help:

Accepted Answer

Promote flexion of the artificial joint

Answer

A Continuous Passive Motion (CPM) machine is used after total knee repair to gently and continuously move the knee joint. Its primary purpose is to prevent stiffness and scar tissue formation, thereby promoting and maintaining the range of motion, particularly flexion, of the artificial joint. This helps in early rehabilitation and improves long-term joint function.

Question 2

Which of the following conditions is most likely related to the development of renal calculi?

Accepted Answer

Gout

Answer

Gout is a metabolic disorder characterized by elevated levels of uric acid in the blood. High uric acid concentrations can lead to the formation of uric acid crystals, which can precipitate in the kidneys and form renal calculi (kidney stones). Therefore, gout is a significant risk factor for developing uric acid kidney stones.

Question 3

The nurse is admitting a client with a suspected duodenal ulcer. The client will most likely report that his abdominal discomfort lessens when he:

Accepted Answer

Eats a meal

Answer

Duodenal ulcer pain is typically described as burning or gnawing, occurring 2-3 hours after a meal or waking the patient at night. The pain is characteristically relieved by eating food, which buffers stomach acid, or by taking antacids. This temporary relief distinguishes it from gastric ulcer pain, which often worsens with food.

Question 4

The physician has scheduled a Whipple procedure for a client with pancreatic cancer. The nurse recognizes that the client’s cancer is located in:

Accepted Answer

The head of the pancreas

Answer

The Whipple procedure, also known as a pancreaticoduodenectomy, is a complex surgical operation primarily performed to remove tumors in the head of the pancreas. This procedure also involves removing parts of the duodenum, gallbladder, and bile duct, making it a major surgery for cancers located specifically in this region.

Question 5

The LPN is reviewing the lab results of an elderly client when she notes a specific gravity of 1.006. The nurse recognizes that:

Accepted Answer

The client has a normal specific gravity.

Answer

The normal range for urine specific gravity is typically 1.005 to 1.030. A specific gravity of 1.006 falls within this normal range, indicating that the client's urine concentration is appropriate. This value does not suggest impaired renal function, dehydration, or fluid overload.
