Mock NCLEX RN Exam Questions
Extract:
Question 1 of 5
The nurse is caring for a client with a history of a retinal detachment who is scheduled for a scleral buckling procedure. The nurse should:
Correct Answer: B
Rationale: Eye drops (e.g., mydriatics) are often ordered pre-scleral buckling to dilate the pupil or reduce pressure. Flat positioning, fluid restriction, and breathing exercises are not standard.
Question 2 of 5
Diabetes mellitus is a disorder that affects 3.1 out of every 1000 children younger than 20 years old. It is characterized by an absence of, or marked decrease in, circulating insulin. When teaching a newly diagnosed diabetes client, the nurse includes information on the functions of insulin:
Correct Answer: A
Rationale: Lack of insulin causes glycogenolysis, catabolism, and hyperglycemia. Insulin promotes the conversion of glucose to glycogen for storage and regulates the rate at which carbohydrates are used by cells for energy. Insulin is anabolic in nature. Glucose stimulates protein synthesis within the tissue and inhibits the breakdown of protein into amino acids.
Question 3 of 5
A client develops an intestinal obstruction postoperatively. A nasogastric tube is attached to low, intermittent suction with orders to 'Irrigate NG tube with sterile saline q1h and prn.' The rationale for using sterile saline, as opposed to using sterile water to irrigate the NG tube is:
Correct Answer: A
Rationale: Water is a hypotonic solution and will deplete electrolytes and cause metabolic acidosis when used for nasogastric irrigation. Irrigating with saline does not cause abdominal discomfort. Severe, colicky abdominal pain is a symptom of intestinal obstruction. Irrigating with water will not cause restlessness or insomnia in the postoperative client. Restlessness and insomnia can be emotional complications of surgery. A nasogastric tube placed in the stomach is used to decompress the bowel. Irrigating with saline ensures a patent, well-functioning tube. Irrigating with saline will not increase peristalsis.
Question 4 of 5
In assessing cardiovascular clients with progression of aortic stenosis, the nurse should be aware that there is typically:
Correct Answer: D
Rationale: These signs are seen in pulmonic stenosis or in response to pulmonary congestion and edema and mitral stenosis. These signs are seen primarily in mitral stenosis or as a late sign in aortic stenosis after left ventricular failure. These signs are seen primarily in right-sided heart valve dysfunction. Left ventricular hypertrophy occurs to increase muscle mass and overcome the stenosis; left ventricular pressures increase as left ventricular volume increases owing to insufficient emptying.
Question 5 of 5
Discharge teaching was effective if the parents of a child with atopic dermatitis could state the importance of:
Correct Answer: D
Rationale: Maintaining a low-humidified environment. Avoiding furry, soft stuffed animals for play, which may increase symptoms of allergy. Avoiding showering, which irritates the dermatitis, and encouraging bathing 4 times a day in colloid bath for temporary relief. Wrapping hands in soft cotton gloves to prevent skin damage during scratching.
