NCLEX-RN Exam Practice Questions

Extract:


Question 1 of 5

The client is admitted with a diagnosis of gestational trophoblastic disease. Which vital sign change is most likely to be observed?

Correct Answer: A

Rationale: Gestational trophoblastic disease can cause maternal tachycardia due to elevated hCG or bleeding. Fetal bradycardia is not relevant (no viable fetus) and hypotension is less common unless hemorrhage occurs.

Question 2 of 5

The client is receiving a continuous infusion of insulin for diabetic ketoacidosis. Which laboratory value should the nurse monitor most closely?

Correct Answer: A

Rationale: Insulin therapy in diabetic ketoacidosis shifts potassium into cells, risking hypokalemia, which can cause arrhythmias. Sodium, BUN, and A1C are monitored but are less critical during acute treatment.

Question 3 of 5

The nurse caring for a client with a head injury would recognize which assessment finding as the most indicative of increased ICP?

Correct Answer: D

Rationale: Papilledema (optic disc swelling) is a specific sign of increased ICP due to pressure on the optic nerve. Vomiting (
A), headache (
B), and dizziness (
C) are less specific and occur in other conditions.

Question 4 of 5

The primary reason that an increase in heart rate (100 bpm) detrimental to the client with a myocardial infarction (MI) is that:

Correct Answer: D

Rationale: Decreased stroke volume and blood pressure will occur secondary to decreased diastolic filling. Tachycardia primarily decreases diastole; systolic time changes very little. Contractility decreases owing to the decreased filling time and decreased time for fiber lengthening. Decreased O2 supply due to decreased time for filling of the coronary arteries increases ischemia and infarct size. Tachycardia primarily robs the heart of diastolic time, which is the primary time for coronary artery filling.

Question 5 of 5

A client with thrombocytopenic purpura is being treated with Neumega (oprelvekin). Which of the following indicates a favorable response to the medication?

Correct Answer: A

Rationale: Neumega (oprelvekin) stimulates platelet production. A platelet count of 150 000/cu.mm indicates a favorable response as it is within the normal range (150 000-450 000/cu.mm). The other options reflect white blood cell or red blood cell indices not platelet counts.
