Basic Adult Health Care NCLEX Questions Questions
Extract:
Question 1 of 5
A nurse is assigned to a client with venous thrombus. The nurse identifies a nursing diagnosis of Impaired physical mobility related to pain. Which should the nurse do first?
Correct Answer: A
Rationale: Elevating the legs (without knee flexion) promotes venous return, reducing pain and swelling in venous thrombus, addressing impaired mobility. Elevating with a pillow under the knees may impede flow, fluids are secondary, and massaging risks dislodging the thrombus.
Question 2 of 5
Lifestyle influences that are considered risk factors for colorectal cancer include:
Correct Answer: C
Rationale: A high-fat, low-fiber diet is a well-established risk factor for colorectal cancer, as it slows digestion and increases exposure to potential carcinogens in the colon.
Question 3 of 5
When using a Doppler instrument to assess peripheral pulses, the correct placement of the transducer is important because it is difficult to differentiate between:
Correct Answer: B
Rationale: Doppler ultrasound can detect both arterial (pulsatile) and venous (continuous) blood flow, but incorrect transducer placement may confuse these signals. Differentiating arterial from venous flow is critical in PVD assessment to confirm arterial patency. Capillary or arteriole flow is less relevant in this context.
Question 4 of 5
Which of the following complications is associated with mechanical ventilation?
Correct Answer: D
Rationale: Mechanical ventilation increases the risk of pulmonary emboli due to immobility and hypercoagulability. Gastrointestinal hemorrhage, immunosuppression, and increased cardiac output are less directly related.
Question 5 of 5
The nurse should instruct a young female adult with sickle cell anemia to do which of the following? Select all that apply.
Correct Answer: A,B,D
Rationale: Sickle cell anemia requires preventive measures to avoid crises. Drinking fluids in hot weather prevents dehydration, a trigger for sickling. Avoiding high-altitude cities reduces hypoxia risk, another trigger. Pregnancy increases the risk of crises due to increased metabolic demands. The statement about being homozygous for HbS is incorrect, as it indicates sickle cell disease, not the trait. Flying on commercial airlines is generally safe if the client is stable.
