RN NCLEX Practice Test Questions
Extract:
Question 1 of 5
The nurse is teaching a client with a history of lactose intolerance about dietary modifications. The nurse should tell the client to avoid:
Correct Answer: A
Rationale: Dairy products contain lactose, which causes gastrointestinal symptoms in lactose intolerance, so they should be avoided.
Question 2 of 5
A client is experiencing muscle weakness and lethargy. His serum K+ is 3.2. What other symptoms might he exhibit?
Correct Answer: B
Rationale: Low potassium (3.2) causes dysrhythmias due to its role in cardiac muscle activity. The other symptoms are not associated with hypokalemia.
Question 3 of 5
The doctor has prescribed aspirin 325 mg daily for a client with transient ischemic attacks. The nurse explains that aspirin was prescribed to:
Correct Answer: D
Rationale: Aspirin reduces platelet aggregation, preventing clot formation in transient ischemic attacks, reducing stroke risk. It does not prevent headaches, boost coagulation, or directly prevent anoxia.
Question 4 of 5
A client has just received an epidural block. She is laboring on her right side. The nurse notes that her blood pressure has dropped from 132/68 to 78/42 mm Hg. The nurse's first action would be to:
Correct Answer: D
Rationale: Nursing measures to support fetal oxygenation and promote maternal blood pressure would precede calling the physician. Systolic pressures below 100 mm Hg or a reduction in the systolic pressure of >30% necessitate treatment. Assessing the blood pressure in 5 minutes may allow for further fetal and/or maternal compromise. Turning the client on her left side will promote uteroplacental perfusion and is appropriate. Oxytocin (Pitocin) increases the strength of uterine contractions and may cause maternal hypotension; thus it is an inappropriate drug for use in this clinical situation. IV fluids would be increased to expand the circulating blood volume and promote increased blood pressure. Turning the mother to her left lateral side promotes uteroplacental perfusion. IV fluids are administered to increase the circulating blood volume, and O2 is administered to promote fetal oxygenation and decrease the nausea accompanying the hypotension.
Question 5 of 5
A child has a nursing diagnosis of fluid volume excess related to compromised regulatory mechanisms. Which of the following nursing interventions is the most accurate measure to include in his care?
Correct Answer: A
Rationale: Although all of these interventions are important aspects of care, weight is the most sensitive indicator of fluid balance. Although monitoring intake and output is important, weight is a more accurate indicator of fluid status. Urine specific gravity does not necessarily indicate fluid volume excess. Edema may not be apparent, yet the client may have fluid volume excess.
